San Antonio Certificate of Occupancy Search: BuildSA, Address Lookup, and Verification

A San Antonio Certificate of Occupancy search can help determine whether City of San Antonio records show an approved business use, commercial tenant-space occupancy, change of use, name update, Temporary Certificate of Occupancy, Certificate of Completion, inspection history, or related permit activity for a property in San Antonio, Texas, United States.

San Antonio occupancy information is distributed across the City’s Certificate of Occupancy resources, BuildSA, current permit and inspection records, Development Services, historical permit data, zoning tools, and separate Bexar County systems for unincorporated property. This guide explains how to search by address or record number, when a new CO is required, when an existing certificate can be updated, how temporary occupancy differs from final approval, and why the official document must be compared with zoning, permits, inspections, licenses, and the proposed business operation.

What a San Antonio Certificate of Occupancy means

A City of San Antonio Certificate of Occupancy, commonly abbreviated as CO or C of O, documents that a building, structure, commercial tenant space, or portion of a building has been approved for a specified occupancy or business use under the applicable City process.

The City requires a Certificate of Occupancy for businesses operating inside San Antonio. A building or commercial space should not be used or occupied before Development Services issues the applicable certificate.

In a multi-tenant building, each tenant space must have its own occupancy approval based on the use approved for that specific suite. A certificate for the shell building, another tenant, another suite, or the overall property may not establish approval for the business location under review.

A reliable San Antonio CO review should match the certificate to the correct:

• street address;
• building, floor, suite, and unit;
• property owner or permit contact;
• business or DBA name;
• approved business use;
• building-code occupancy classification;
• floor area and occupant load;
• building and trade permits;
• fire and life-safety requirements;
• inspection history;
• date and type of approval.

The existence of a CO does not mean that every possible business can operate at the property. The proposed operation may still require zoning confirmation, remodeling permits, trade permits, fire approval, health permits, alcohol approval, professional licensing, parking review, or another regulatory process.

When a San Antonio Certificate of Occupancy is required

A San Antonio Certificate of Occupancy process may be required when:

• a newly constructed commercial building will be occupied;
• an individual tenant finish-out is completed;
• a commercial tenant space will begin operating;
• the business use changes;
• the occupancy classification changes;
• the premises are remodeled or reconfigured in a way affecting occupancy;
• the business expands into another suite or portion of the building;
• the existing certificate cannot be verified as valid for the proposed use;
• a regulated business type requires a new application under City rules;
• a temporary or phased occupancy request is needed during construction.

A change in ownership or tenant does not always require a completely new certificate when the approved business use and occupancy classification remain substantially the same. In that situation, an update or name-change request may be appropriate.

The distinction depends on the actual use of the premises—not simply the company name, industry description, or what the previous tenant appeared to do.

Confirm the jurisdiction and tenant space first

A mailing address containing “San Antonio” does not automatically establish that the property is inside San Antonio city limits or that the City of San Antonio issued the applicable occupancy record.

The wider San Antonio market includes:

• property inside the City of San Antonio;
• unincorporated Bexar County;
• other incorporated municipalities in Bexar County;
• property within an extraterritorial jurisdiction;
• special districts and utility-service areas;
• locations subject to separate county, fire, floodplain, infrastructure, or environmental review.

Before searching or interpreting a CO, confirm:

• the complete postal address;
• the municipal boundary;
• the county;
• the parcel and legal property description;
• the building number;
• the floor, suite, lease space, or unit;
• the former business use;
• the proposed business use;
• whether the premises were divided, combined, expanded, or remodeled.

Suite-level verification is especially important for shopping centers, office buildings, industrial parks, warehouses, medical buildings, strip centers, mixed-use developments, and other multi-tenant properties.

Official San Antonio Certificate of Occupancy sources

City of San Antonio Certificate of Occupancy page

The official City of San Antonio Certificate of Occupancy page explains the current requirements for new construction, change of use, existing CO updates, temporary occupancy, regulated business types, and Certificates of Completion.

Use this page as the primary procedural source rather than relying on an old third-party article or a historical search result.

BuildSA

BuildSA is the City’s current online environment for building and fire permit applications, project documents, contractor licensing, inspections, and related development workflows.

BuildSA can help identify:

• current building-permit records;
• commercial remodel or tenant-finish-out activity;
• trade permits;
• fire permits;
• inspection activity;
• project and application identifiers;
• records connected to the occupancy process.

A permit or application record in BuildSA is not necessarily the final Certificate of Occupancy. Review the record status, inspections, linked permits, and final issuance.

Business and Commercial Projects resources

The Business and Commercial Projects page connects zoning, plan intake, plan review, the permit process, inspections, utility release, property addressing, and the Certificate of Occupancy process.

This is useful when the occupancy question must be reviewed as part of a wider construction or business-opening workflow.

Small Business Permitting Guide

The City’s Small Business Permitting Guide explains the distinction between a new CO application and a name update when a valid certificate already covers the same business use and occupancy classification.

It also identifies the typical inspection disciplines connected to a new occupancy review.

Hansen Legacy Permit Data Portal

The Hansen Legacy Permit Data Portal supports historical research for issued permits from April 2003 through November 2020, together with a limited group of records from 1998 through 2003.

The legacy search includes a Certificate of Occupancy record type, but it contains only records that reached the issued stage and remain available under the applicable retention rules.

Development Services and records assistance

Development Services provides Certificate of Occupancy assistance through its One Stop services and current contact channels.

When the required document is not available through a basic online search, provide:

• the complete address;
• building and suite number;
• current and former business names;
• permit, application, or project number;
• approximate issue date;
• the exact certificate, inspection report, permit, plan, or record required.

How to search San Antonio Certificate of Occupancy records by address

A reliable San Antonio CO lookup by address normally combines current BuildSA records, permit history, inspection records, legacy data where applicable, and direct Development Services verification.

1. Confirm that the property is inside the City of San Antonio.
2. Record the complete street address, directional prefix, suffix, building, floor, suite, and unit.
3. Search the address through current BuildSA or City permit-search resources.
4. Search both the exact tenant-space address and the base-building address.
5. Review commercial building, remodel, tenant-finish-out, trade, fire, and occupancy-related records.
6. Identify every relevant permit, project, application, inspection, and CO number.
7. Compare the current business name with previous tenants, DBAs, applicants, contractors, and project names.
8. Determine whether the record represents a final CO, application, name update, TCO, Certificate of Completion, permit, or inspection event.
9. Search the legacy portal when the occupancy may have been issued before December 2020.
10. Review zoning and the proposed business use.
11. Obtain or verify the official certificate when the result affects a material decision.

How to search by CO, permit, or record number

An official record number is normally more precise than an address because it identifies one specific application, permit, inspection, or occupancy record.

1. Enter the complete record number into the applicable current or legacy City search.
2. Confirm the address and suite.
3. Confirm the record type.
4. Review the official status.
5. Check application, issue, expiration, completion, or inspection dates.
6. Review the business use and occupancy description.
7. Identify the linked building and trade permits.
8. Review required and completed inspections.
9. Search the address independently for later or related records.
10. Verify the final certificate when the record itself affects a lease, license, or business-opening decision.

A single project can generate a commercial building permit, electrical permit, mechanical permit, plumbing permit, fire-system permit, inspection records, utility-release activity, a Temporary Certificate of Occupancy, and a final Certificate of Occupancy.

Existing CO and business-name changes

When a property or tenant space already has a valid Certificate of Occupancy and the proposed business use and occupancy classification remain substantially the same, a new CO may not be required solely because the owner, lessee, or business name changes.

In that situation, the business may request an update or name change to the existing certificate.

Before relying on the update process:

1. confirm that the existing CO is valid;
2. confirm that it applies to the exact suite;
3. identify the approved business use;
4. compare the previous and proposed operations;
5. confirm that the occupancy classification remains the same;
6. review whether any regulated-business exception applies;
7. review later remodeling or permit activity;
8. submit the applicable update application.

Similar company descriptions do not necessarily establish the same approved use. Equipment, customer activity, food or alcohol service, storage, hazardous materials, occupant load, vehicles, operating hours, and physical layout can affect the classification.

Change of use and new Certificate of Occupancy applications

A new Certificate of Occupancy is required when the proposed business is a different type of operation from the use currently approved for the premises.

A change-of-use review can involve:

• zoning review;
• building inspection;
• electrical inspection;
• mechanical inspection;
• plumbing inspection;
• fire inspection;
• health inspection where applicable;
• parking and site review;
• occupant-load review;
• accessibility review;
• additional building or trade permits;
• operational licensing.

The City uses the example of converting a clothing store into a hair salon: although both are commercial businesses, the change in activity requires a new occupancy review.

The application itself does not authorize the business to open. Required inspections, corrections, permits, and approvals must be completed before the final CO is issued.

Businesses that may always require a new San Antonio CO

San Antonio identifies certain business types that require a new Certificate of Occupancy even when the proposed use appears similar to the previous operation.

Current City examples include:

• bed and breakfasts;
• boarding homes;
• community homes and assisted-living facilities;
• head shops;
• live-entertainment businesses;
• salvage yards and metal-recycling facilities;
• transitional homes.

These operations may also require an Occupancy Classification Letter or additional use-specific review.

Other regulated activities—such as restaurants, alcohol-related businesses, childcare, healthcare, food establishments, hazardous-material users, or assembly occupancies—may require additional City, county, State of Texas, or federal approvals.

New construction, shell buildings, and tenant finish-out

New commercial construction

For new construction, the Certificate of Occupancy is issued after the required inspections and approvals are completed.

The building permit, trade permits, fire requirements, inspections, utility release, and occupancy process should be reviewed as connected but separate stages.

Multi-tenant and shell buildings

A completed shell building is not the same as a finished and approved tenant space.

Once shell inspections are complete, the City may issue a Certificate of Completion or comparable shell completion documentation. Each individual tenant finish-out must still obtain its required permits, inspections, and Certificate of Occupancy based on the approved use.

Tenant finish-out

A tenant finish-out can require:

• a commercial remodel or finish-out permit;
• architectural and floor plans;
• electrical permits;
• mechanical permits;
• plumbing permits;
• fire-system review;
• health review;
• final building and trade inspections;
• a separate CO for the tenant space.

Review the San Antonio Building Permit Search Guide when the central question concerns construction, remodeling, trade permits, plan review, or inspections.

San Antonio Temporary Certificate of Occupancy

A Temporary Certificate of Occupancy, or TCO, may allow specified portions of a building to be occupied after the required work and safety conditions for those portions have been completed.

A TCO may be used during a phased construction process. For example, it may allow limited activities such as:

• staff training;
• moving equipment into an approved area;
• installing furniture;
• setting up appliances;
• using a completed portion of a larger building;
• preparing for final occupancy.

A TCO should be reviewed for:

• the exact areas authorized;
• the activities allowed;
• the conditions attached to approval;
• outstanding inspections;
• open building or trade permits;
• expiration or phase limitations;
• whether normal business operation is permitted.

Certificate of Completion versus Certificate of Occupancy

San Antonio may issue a Certificate of Completion for:

• a shell building with multiple suites that is not yet finished for individual tenants;
• a construction project that does not require a new Certificate of Occupancy.

Required inspections must still be approved before a Certificate of Completion is issued.

A Certificate of Completion should not be treated as:

• a tenant-specific Certificate of Occupancy;
• approval for a particular business use;
• confirmation that every suite is ready for operation;
• permission to occupy unfinished areas;
• a substitute for tenant finish-out permits.

Inspections and final CO approval

The required inspections depend on the business use, occupancy classification, existing building conditions, construction scope, and applicable regulatory requirements.

Typical inspections can include:

• building;
• electrical;
• mechanical;
• plumbing;
• fire and life safety;
• health;
• accessibility;
• use-specific inspections.

Fire inspection requirements can involve:

• egress;
• occupant load;
• fire alarms;
• sprinkler or suppression systems;
• fire lanes and access;
• hazardous materials;
• high-pile storage;
• assembly uses;
• other life-safety conditions.

Missing or incorrectly linked trade permits can delay final occupancy approval. The full project history should be reviewed when a business-opening timeline depends on the certificate.

What San Antonio occupancy records may show

Available fields depend on whether the user is reviewing a CO application, BuildSA record, legacy record, inspection entry, commercial permit, TCO, Certificate of Completion, or final certificate.

San Antonio occupancy-related records may contain or connect to:

• Certificate of Occupancy number;
• permit, application, or project number;
• property address;
• building, floor, suite, or unit;
• property owner;
• business or DBA name;
• approved business use;
• occupancy classification;
• occupant load;
• floor area;
• application date;
• issue or completion date;
• official status;
• building and trade permits;
• inspection disciplines and results;
• fire or health review;
• Temporary Certificate information;
• Certificate of Completion information;
• available plans or supporting documents.

Not every record contains every field. Relevant information may be distributed among several permits, inspection records, applications, plan-review documents, fire files, health records, and the final certificate.

How to interpret a San Antonio Certificate of Occupancy correctly

A Certificate of Occupancy does not independently establish:

• current tenancy;
• active business operation;
• property ownership;
• financial condition;
• active professional or operational licenses;
• compliance with every state or federal requirement;
• the current physical condition of the property;
• the commercial suitability of the location today.

Certificate of Occupancy versus zoning, permits, and licenses

A CO is not zoning approval for every business

The approved occupancy does not mean every other use is allowed at the property. The proposed business must be compatible with the property’s zoning and applicable use regulations.

Review the San Antonio Zoning by Address Guide when the central question concerns the zoning district, overlays, permitted uses, zoning cases, or formal verification.

A CO is not a building permit

A Certificate of Occupancy does not authorize remodeling, structural alterations, electrical work, mechanical work, plumbing, fire systems, signs, demolition, or site development.

A CO is not a business or professional license

Food establishments, alcohol-related businesses, healthcare operations, childcare facilities, assisted-living operations, salons, transportation businesses, industrial users, entertainment venues, and other regulated activities may require additional approvals.

A CO is not a fire or health permit

Fire, food, environmental, health, alcohol, and other regulatory requirements may create separate applications, inspections, permits, or licenses.

A CO is not evidence of current occupancy

A historical certificate can remain in the property record after the tenant has moved or the premises have changed.

What to do when no San Antonio CO is found

A missing online result does not automatically mean that the property or tenant space never received a Certificate of Occupancy.

Possible reasons include:

• the property is outside San Antonio city limits;
• the certificate uses the base-building address;
• the record identifies a former tenant or DBA;
• the CO predates the current BuildSA system;
• the certificate is indexed under another permit or project number;
• the suite number changed;
• the premises were combined with or divided from another suite;
• the record is a TCO or Certificate of Completion rather than a final CO;
• the document requires direct Development Services assistance;
• Bexar County or another municipality issued the relevant approval.

1. Confirm the jurisdiction.
2. Search the complete suite address.
3. Search the base-building address.
4. Search previous business and DBA names.
5. Search known permit, application, and project numbers.
6. Review current BuildSA records.
7. Review the Hansen Legacy Permit Data Portal.
8. Review building, trade, fire, and inspection records.
9. Contact Development Services for verification or an existing record.
10. Search Bexar County records when county jurisdiction may apply.

Do not publish or rely on the statement “no Certificate of Occupancy exists” solely because one online search returned no result.

City of San Antonio versus Bexar County occupancy records

A City of San Antonio Certificate of Occupancy and a Bexar County occupancy or compliance certificate belong to separate regulatory systems.

City of San Antonio Development Services handles applicable occupancy, permitting, inspection, and zoning workflows for property inside the City.

In unincorporated Bexar County, the Fire Marshal and Public Works departments operate separate construction and change-of-occupancy procedures.

Bexar County change of occupancy

A new business opening in an existing structure in unincorporated Bexar County may need to submit a Change of Occupancy Application.

The county process can include:

• Public Works authorization;
• a Fire Marshal application;
• inspection of the premises;
• building and fire-code review;
• corrections where necessary;
• issuance of a change-of-occupancy certificate when approved.

New Bexar County commercial construction

New commercial and public-access buildings in applicable unincorporated county areas may require:

• building-permit application;
• construction-plan review;
• Fire Marshal review;
• construction inspections;
• fire-protection-system permits;
• final inspection;
• a Certificate of Occupancy or Compliance under the county process.

San Antonio commercial occupancy checklist

Before relying on a CO for a lease, acquisition, tenant placement, business opening, buildout, financing, or regulated operation, review the following:

1. Confirm the municipality, county, and city-limit boundary.
2. Confirm the exact address, building, floor, suite, and unit.
3. Identify the previous and proposed business uses.
4. Search current BuildSA and City permit records.
5. Search the legacy portal when historical records may apply.
6. Identify all CO, permit, application, project, and inspection numbers.
7. Obtain or verify the official certificate.
8. Confirm that the certificate applies to the exact tenant space.
9. Confirm the approved business use and occupancy classification.
10. Determine whether the proposed operation is the same use or a change of use.
11. Check whether a regulated-business exception requires a new CO.
12. Review later remodeling or tenant-finish-out permits.
13. Review electrical, mechanical, plumbing, and fire permits.
14. Review required and completed inspections.
15. Review zoning and parking requirements.
16. Identify health, alcohol, professional, and operational licenses.
17. Distinguish a TCO or Certificate of Completion from a final CO.
18. Confirm whether Bexar County or another authority has jurisdiction.
19. Obtain agency or professional confirmation when the decision is material.

This checklist identifies unanswered questions before a commercial commitment. It does not replace an official City or county determination, legal advice, architectural review, engineering analysis, title research, or professional property due diligence.

Commercial uses of San Antonio Certificate of Occupancy data

Pre-lease screening

Tenants, landlords, brokers, and site-selection teams can use CO records to determine whether a tenant space has an approved historical use and whether the proposed operation may require a name update, new CO, remodeling permits, or change-of-use review.

Commercial real estate due diligence

Occupancy records can be compared with zoning, permits, plans, inspections, fire records, property information, later alterations, and tenant history.

Business-opening and tenant-movement research

A new CO application, name update, TCO, tenant finish-out, change-of-use permit, or inspection can indicate activity at a business location.

The record should be corroborated before it is described as a confirmed opening, relocation, expansion, or active lease.

Regulated-business location review

Restaurants, bars, healthcare facilities, assisted-living operations, boarding homes, childcare facilities, salons, entertainment venues, recycling facilities, warehouses, and other regulated uses may require occupancy review together with additional permits and licenses.

Contractor and vendor research

A change of use, tenant finish-out, failed inspection, required correction, fire upgrade, or occupancy review may identify demand for construction, electrical, mechanical, plumbing, fire, design, accessibility, equipment, or professional services.

An occupancy record is a research signal, not a guaranteed contract or sales lead.

B2B account and market screening

At scale, occupancy records can support tenant-movement research, location screening, regulated-business analysis, development monitoring, and account prioritization when combined with permits, procurement, housing, transportation, regulatory, public-funding, and other official-source records.

Risk and compliance-facing research

Missing certificates, unresolved inspections, conflicting uses, incomplete permits, expired temporary approvals, or inconsistent jurisdictional records may identify questions requiring verification.

These signals should not be described as violations or legal conclusions unless the controlling official record expressly establishes that status.

Limitations of San Antonio Certificate of Occupancy searches

San Antonio occupancy records are useful, but no single public source provides a complete commercial due-diligence answer.

Important limitations include:

• current and historical records can be divided between BuildSA and the legacy system;
• an application or permit row is not necessarily a final certificate;
• address and suite formats may vary;
• one building may contain many independent tenant spaces;
• a historical CO may identify a former business or use;
• an existing certificate may require a name update or new application;
• certain business types require additional occupancy review;
• a TCO is not permanent final approval;
• a Certificate of Completion is not a tenant-specific CO;
• a CO does not authorize construction;
• a CO does not replace zoning, fire, health, alcohol, or professional licensing;
• City of San Antonio and Bexar County records have different legal meanings;
• a CO does not prove that a business currently operates at the address;
• a missing online result is not a final official determination.

When a lease, acquisition, regulated operation, construction project, financing decision, or substantial investment depends on the result, obtain the official record and verify current requirements with the responsible authority or an appropriately qualified professional.

Common San Antonio Certificate of Occupancy questions

Does every San Antonio business need a Certificate of Occupancy?

The City states that businesses operating inside San Antonio require a Certificate of Occupancy and that each tenant space in a multi-tenant building must have occupancy approval based on its approved use.

Can I search a San Antonio CO by address?

Begin with current BuildSA and City permit-search resources. Search both the exact suite and the base-building address, then review related permits, inspections, and legacy records where applicable.

Does a new tenant always need a completely new CO?

Not always. When the valid existing CO covers substantially the same business use and occupancy classification, a name update may be appropriate. Certain regulated business types and changes in use still require a new application.

What happens when the business use changes?

A new Certificate of Occupancy is required. The process may involve building, electrical, mechanical, plumbing, fire, health, zoning, and other reviews.

What is a San Antonio Temporary Certificate of Occupancy?

A TCO is a limited approval allowing specified completed and safe portions of a building to be used before the full final CO is issued. Its scope and conditions must be reviewed carefully.

Does a TCO allow normal business operation?

Not automatically. Confirm the activities and areas authorized and whether all required temporary-occupancy inspections have been approved.

What is a Certificate of Completion?

It documents completion of applicable construction or shell-building work after required inspections. It does not replace the separate CO required for an individual tenant space and approved business use.

Can an existing CO simply be renamed?

Potentially, when the certificate remains valid and the business use and occupancy classification do not materially change. The applicable update application must still be submitted.

Where can I find older San Antonio CO records?

The Hansen Legacy Permit Data Portal can contain issued Certificate of Occupancy records from April 2003 through November 2020 and a limited group from 1998 through 2003.

Does a San Antonio CO authorize remodeling?

No. Construction and trade work require their own permits and inspections.

Does a CO prove that a business is currently open?

No. It documents an approved use or occupancy at a point in time. It does not prove present tenancy, active operation, ownership, or a current commercial opportunity.

Are San Antonio and Bexar County occupancy certificates the same?

No. They are issued under different jurisdictions and procedures. Confirm whether the property is inside the City of San Antonio, another municipality, or unincorporated Bexar County.

How Registry Intelligence structures San Antonio occupancy signals

City of San Antonio, Bexar County, and other official systems remain the controlling sources for Certificates of Occupancy, occupancy applications, permits, inspections, zoning, fire records, health requirements, and current development procedures.

Registry Intelligence does not replace BuildSA, City Development Services, Bexar County permit systems, direct agency verification, public-record requests, legal review, or professional property due diligence.

The San Antonio Commercial Intelligence Module structures selected official-source records into a buyer-facing review layer covering development, construction, housing, public funding, procurement, transportation, regulatory activity, and federal or JBSA-facing market context.

Occupancy-related records can be reviewed alongside organizations, projects, locations, event history, analytical layers, record classifications, dates, source context, and derived research signals.

This structure is designed to support B2B account research, contractor and vendor targeting, commercial real estate review, tenant-movement screening, regulated-location analysis, market research, risk context, and evidence-backed investigation before the user returns to the controlling official record for final verification.
