Houston Certificate of Occupancy Search: Records, Inspections, and Verification

A Houston Certificate of Occupancy search can help determine whether City of Houston records show an approved commercial occupancy, lease-space use, change in occupancy classification, occupancy inspection, duplicate certificate, or related permit history for a property in Houston, Texas.

Houston occupancy information is distributed across the Houston Permitting Center, Occupancy Inspections, the City of Houston Permit Portal, permit and inspection records, and separate Open Records procedures. Properties outside Houston city limits may instead fall under Harris County or another municipality, so the responsible jurisdiction must be confirmed before the result is used for a lease, business opening, buildout, acquisition, or compliance decision.

What a Houston Certificate of Occupancy means

A City of Houston Certificate of Occupancy, commonly abbreviated as CO, documents that a commercial building, individual lease space, or portion of a building has been approved for a particular occupancy or use under the applicable City process.

Houston requires commercial tenants and owners to have a valid CO for the use of the building or lease space. The certificate is normally issued during construction, remodeling, or a change in use or occupancy classification.

A Houston CO may be relevant to:

• an office or professional-service business;
• a retail store;
• a restaurant or food establishment;
• a medical or healthcare facility;
• a warehouse or distribution location;
• an industrial or manufacturing operation;
• a personal-service business;
• an entertainment or assembly use;
• a commercial building containing several tenant spaces;
• an existing property changing to a different occupancy classification.

The CO should correspond to the exact premises and approved use. A certificate for the overall building, a different suite, a former tenant, or a different occupancy classification may not answer the question for the current business proposal.

Multiple rooms or spaces under one tenancy may sometimes be covered by one certificate. That does not mean that separate tenants, independently operated suites, or materially different uses can rely on the same CO without further City review.

When a Houston Certificate of Occupancy is required

City guidance identifies the following principal circumstances:

• a commercial building is being occupied;
• an individual lease space inside a commercial building is being occupied;
• an existing occupancy classification changes;
• a new building is completed and prepared for occupancy;
• a commercial building or lease space is remodeled;
• an existing premises does not have a locatable valid CO;
• a change of use requires new plans, permits, inspections, or occupancy approval.

A business should not assume that the prior tenant’s certificate automatically authorizes the new operation. The proposed business may have a different occupancy classification, customer load, equipment, storage, fire risk, food-service activity, hazardous-material use, floor plan, or code requirement.

When an occupancy classification changes, the City states that plans and permits must be approved before a new CO can be obtained for the new use or occupancy.

Confirm the jurisdiction and lease space first

A mailing address containing “Houston” does not necessarily establish that the property is inside Houston city limits or that the City of Houston controls every occupancy, permit, fire, floodplain, or development requirement.

The Houston market includes:

• property inside the City of Houston;
• unincorporated Harris County;
• other incorporated municipalities;
• municipal extraterritorial jurisdictions;
• special-purpose and utility districts;
• properties subject to separate county, fire, floodplain, or infrastructure review.

Before searching, confirm:

• the complete street address;
• the municipality and city limits;
• the county;
• the parcel and building;
• the floor, suite, lease space, or unit;
• the previous business use;
• the proposed business use;
• whether the premises have been remodeled or reconfigured;
• whether multiple buildings or tenant spaces share the same address.

Suite-level identification is particularly important in shopping centers, office buildings, industrial parks, medical buildings, warehouses, and mixed-use developments. A CO associated with the base address may relate to another building or tenant space.

Official Houston Certificate of Occupancy sources

Houston Permitting Center Occupancy Inspections

The Occupancy Inspections section is the primary official resource for existing commercial structures, lease spaces, changes of use, and occupancy-record requests associated with buildings constructed after 1988.

The section:

• permits Certificates of Occupancy for existing commercial structures;
• handles change-of-use occupancy processes;
• performs occupancy inspections;
• enforces applicable past and current building-code requirements;
• processes certain occupancy-record requests;
• handles related life-safety review where required.

City of Houston Permit Portal

The Houston Permit Portal is a real-time City source for permitting information.

Portal users can:

• search for permits;
• apply for permits;
• print permits;
• make payments;
• request inspection schedule dates;
• follow permit progress from submission to issuance.

The permit portal can help locate building, remodeling, trade, inspection, and other records connected to an occupancy question. A portal entry is not necessarily the final Certificate of Occupancy document.

Houston Permitting Center Open Records

The Houston Permitting Center Open Records section processes Texas Public Information Act requests for Building Code Enforcement and Office of the City Engineer records.

Its listed responsibilities include:

• Certificates of Occupancy from 1972 through 1988;
• commercial plans and drawings from 1972 to the present;
• construction and inspection records;
• permit-history summaries;
• other records maintained by the applicable service lines.

The City states that research and processing of a request may take up to 10 business days. The requester is informed whether responsive records were located and can request inspection, copies, or both.

City of Houston Public Information Request Center

The City also operates a central Public Information Act request system through GovQA.

A public-information request must ask for records that already exist. The City is not required to create a new analysis, compile a custom dataset, conduct legal research, or answer general questions through the records-request process.

Occupancy and building-permit records should be directed to the department that maintains the information, generally Houston Public Works or the relevant Houston Permitting Center section.

How to search Houston Certificate of Occupancy records by address

Houston does not provide every occupancy record through one simple address directory. A reliable search normally combines the Permit Portal, Occupancy Inspections, permit history, inspection records, and records-request procedures.

1. Confirm that the property is inside the City of Houston jurisdiction.
2. Record the complete street address, building, floor, suite, and unit.
3. Search the property through the Houston Permit Portal.
4. Review building, remodeling, trade, inspection, and occupancy-related records connected to the address.
5. Search both the exact suite and the base-building address.
6. Record every relevant permit, project, and inspection number.
7. Compare the current business name with previous tenants, project names, applicants, and property records.
8. Determine the approximate construction, remodeling, tenant-change, or occupancy date.
9. Contact Occupancy Inspections for an existing-building CO or post-1988 occupancy-record request.
10. Use Open Records for a qualifying historical CO, plans, inspections, or permit-history summary.
11. Obtain the official record when the result affects a lease, acquisition, license, buildout, financing, or compliance decision.

Existing building and lease-space CO applications

For an existing commercial building or lease space, the Houston Permitting Center instructs applicants to submit the Occupancy Compliance Inspection application and supporting information to Occupancy Inspections.

The requested application information includes:

• the new business name, when the application concerns a new business;
• the complete business address;
• a telephone number;
• approximate square footage;
• the number of floors;
• the present or proposed type of business;
• the previous business type, when known;
• a site map when several buildings are located on the property;
• the applicable inspection fee.

The information is used to identify the premises, understand the proposed occupancy, determine the appropriate review, and schedule the inspection process.

An application does not itself establish approval. The premises must complete the applicable inspections, corrections, permits, and final approvals before the certificate is issued.

Houston occupancy inspection process

After the application is accepted, the applicant is given an inspection date. City inspectors visit the premises and document applicable code discrepancies.

The inspection may address:

• structural conditions;
• electrical conditions;
• mechanical systems;
• plumbing systems;
• means of egress;
• life-safety requirements;
• the condition and classification of the premises;
• work requiring separate building or trade permits.

Existing buildings may be evaluated under the code edition applicable when they were constructed together with applicable minimum life-safety requirements.

The City states that an inspection report is normally generated and sent to the applicant within approximately one week. The report identifies required corrections and indicates whether separate structural, electrical, mechanical, or plumbing permits are needed.

Applicants are generally given 180 days to obtain required permits and complete corrections. Electrical, mechanical, and plumbing permits must be obtained by appropriately licensed contractors when those permits are required.

After the repairs and required final inspections are approved, the applicant coordinates with Occupancy Inspections regarding issuance or collection of the Certificate of Occupancy.

Duplicate and historical Houston CO records

Duplicate Certificate of Occupancy

The City states that when an existing building or lease space has not been modified but the CO cannot be located, a duplicate Certificate of Occupancy must be obtained.

A duplicate is a replacement record. It does not authorize:

• a new occupancy classification;
• a material change in business use;
• unpermitted remodeling;
• an expansion into another suite;
• construction or trade work;
• a different operation that requires additional review.

Buildings constructed after 1988

Occupancy Inspections states that it completes occupancy-record requests for buildings constructed after 1988.

Provide the complete address, suite, approximate construction or occupancy date, business name, and known permit or project numbers to improve the accuracy of the request.

Certificates from 1972 through 1988

The Houston Permitting Center Open Records section lists Certificates of Occupancy from 1972 through 1988 among the records it processes.

Historical research may also require commercial plans, construction records, inspection records, and a summary of permit history to understand whether later alterations or changes affected the original occupancy.

Records outside the published date ranges

When the building or occupancy record falls outside a clearly stated public-search period, contact the appropriate City section rather than assuming that no record exists.

Older records may be incomplete, stored under different identifiers, associated with a former address format, or require manual archival research.

What Houston occupancy records may show

Available information depends on whether the user is reviewing an application, permit entry, inspection report, duplicate request, permit-history summary, or the final certificate.

Houston CO-related records may contain or connect to:

• property address;
• building and lease-space information;
• business name;
• present or proposed business type;
• previous business type;
• approximate square footage;
• number of floors or buildings;
• occupancy classification;
• permit or project numbers;
• application and inspection dates;
• code discrepancies;
• required structural or trade permits;
• corrections and reinspection requirements;
• final inspection status;
• certificate issue information;
• related plans, drawings, or construction records.

Not every record contains every field. The required information may be divided among the application, inspection report, building permit, trade permits, plans, fire records, permit-history summary, and final certificate.

How to interpret a Houston Certificate of Occupancy

A CO establishes occupancy context at a particular point in the City process. It does not independently establish:

• current tenancy;
• current business operation;
• property ownership;
• the validity of every business license;
• compliance with every fire, health, state, or federal requirement;
• the condition of the building today;
• the suitability of the premises for a proposed commercial operation.

City of Houston versus Harris County occupancy records

A City of Houston Certificate of Occupancy and a Harris County Certificate of Compliance are not the same document.

City of Houston CO procedures apply to applicable commercial buildings and lease spaces under City jurisdiction.

Harris County operates a separate permitting and Certificate of Compliance process for county-regulated commercial projects. County guidance connects its Certificate of Compliance process to required permits, completed inspections, fire review, floodplain requirements, site development, and other Harris County regulations.

For a Harris County property, review:

• the county project and permit number;
• commercial-building or tenant-improvement permits;
• required inspections;
• Fire Marshal review;
• floodplain and site-development requirements;
• the Harris County Certificate of Compliance;
• any separate municipal or special-district approvals.

Certificate of Occupancy versus other Houston records

A CO is not a building permit

A Certificate of Occupancy does not authorize remodeling, structural changes, electrical work, plumbing, mechanical work, fire-protection work, signs, or other construction.

Review the Houston Building Permit Search Guide for construction, remodeling, inspections, project status, and permit-history research.

A CO is not conventional zoning approval

Houston does not have conventional citywide zoning, but properties remain subject to development regulations, subdivision and platting requirements, building lines, parking rules, deed restrictions, permits, floodplain controls, and other location-specific requirements.

Review the Houston Land-Use, Deed Restrictions, and Development Controls Guide when the question concerns whether a proposed operation or development is compatible with the property.

A CO is not a business license

Restaurants, alcohol-related operations, healthcare facilities, food establishments, industrial users, personal-service businesses, and other regulated activities may require separate City, county, State of Texas, or federal permits and licenses.

A CO is not a fire inspection record

Fire-code review, hazardous-material regulation, alarm or suppression systems, occupant load, and life-safety conditions may involve separate Houston Fire Department records.

A CO is not proof of present occupancy

An issued certificate may remain in the historical property file after the tenant has moved, the business has closed, the space has been reconfigured, or a different operation has begun.

Houston commercial occupancy checklist

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

1. Confirm whether the property is inside the City of Houston.
2. Confirm the complete address, building, floor, suite, and unit.
3. Identify the previous and proposed business uses.
4. Search the Houston Permit Portal.
5. Identify the relevant permit, project, inspection, and occupancy numbers.
6. Obtain the official CO or occupancy record.
7. Confirm that the record applies to the exact lease space.
8. Confirm the approved occupancy classification.
9. Review later remodeling and change-of-use activity.
10. Review open or required building and trade permits.
11. Review final inspection results.
12. Check fire and life-safety requirements.
13. Review deed restrictions and development controls.
14. Check floodplain, site-development, and infrastructure requirements.
15. Identify separate health, alcohol, professional, or operational licenses.
16. Determine whether Harris County or another authority also has jurisdiction.
17. Obtain City or professional confirmation when the decision is material.

This checklist is intended to identify unresolved questions before a commercial commitment. It is not a substitute for City confirmation, legal advice, architectural review, engineering analysis, title research, or professional property due diligence.

What to do when no Houston CO is found

A missing online result does not automatically mean that the premises never received a Certificate of Occupancy.

Possible reasons include:

• the property is outside Houston city limits;
• the record uses the base-building address rather than the suite;
• the record is associated with a former business name;
• the record predates the current permit system;
• the CO is held by Occupancy Inspections or Open Records;
• the record is associated with a permit or project number;
• the premises were reconfigured after the certificate was issued;
• the record is a duplicate or historical occupancy file;
• Harris County or another municipality controls the property;
• the address format differs from the current postal address.

1. Confirm the jurisdiction.
2. Search the exact suite address.
3. Search the base-building address.
4. Search previous business and project names.
5. Search known permit and project numbers.
6. Review inspection and remodeling records.
7. Contact Occupancy Inspections for applicable post-1988 records.
8. Use Open Records for qualifying historical records and permit history.
9. Search Harris County ePermits when county jurisdiction may apply.

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

Commercial uses of Houston Certificate of Occupancy data

Pre-lease screening

Tenants, brokers, and landlords can use occupancy records to determine whether a lease space has a documented occupancy history and whether the proposed business may require inspection, corrections, remodeling permits, or a new occupancy process.

Commercial real estate due diligence

CO records can be compared with permit history, plans, inspections, deed restrictions, development controls, floodplain context, and later property changes.

Business-opening research

A new occupancy application, inspection, remodel, or related permit may indicate activity at a commercial address.

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

Regulated-business location review

Restaurants, healthcare facilities, warehouses, industrial users, personal-service businesses, entertainment venues, food establishments, and other regulated operations may require occupancy review together with additional permits and licenses.

Contractor and vendor research

Occupancy inspections can identify corrections requiring structural, electrical, mechanical, plumbing, fire, life-safety, design, or professional services.

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

B2B account and market screening

At scale, occupancy records can support location screening, tenant-movement research, regulated-business analysis, market mapping, and account prioritization when combined with permits, property, logistics, healthcare, environmental, infrastructure, and other official-source signals.

Compliance-facing research

Missing certificates, change-of-use activity, required corrections, open permits, or incomplete inspections may identify questions requiring official verification.

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

Limitations of Houston Certificate of Occupancy searches

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

Important limitations include:

• occupancy information is divided among several City systems and sections;
• current portal entries may not include the final certificate document;
• historical records follow different request procedures;
• address and suite formats may vary;
• one address may contain several buildings and tenant spaces;
• a historical CO may relate to a former business or occupancy;
• a duplicate CO does not approve a changed use;
• an application or inspection is not a final CO;
• a CO does not authorize construction;
• a CO does not replace fire, health, business, or professional licensing;
• City of Houston and Harris County documents 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 public authority or an appropriately qualified professional.

Common Houston Certificate of Occupancy questions

Does a commercial business in Houston need a Certificate of Occupancy?

City guidance states that commercial buildings and individual commercial lease spaces must have a valid CO before occupancy, and a new CO may be required when the occupancy classification changes.

Can I search a Houston CO by address?

Begin with the Houston Permit Portal and search the associated permit and inspection records. For the actual occupancy record, contact Occupancy Inspections or Open Records according to the building and record date.

Where do I request a Houston CO for an existing lease space?

Existing commercial-building and lease-space applications are handled by the Houston Permitting Center Occupancy Inspections section using the applicable Occupancy Compliance Inspection application.

What happens when the business use changes?

A change in occupancy classification requires plans and permits to be approved before a new CO is obtained for the new use or occupancy.

What happens if the original CO cannot be located?

When the existing premises have not been modified, the City identifies a duplicate CO as the appropriate process.

Where do I request Houston occupancy records after 1988?

Occupancy Inspections states that it processes occupancy-record requests for buildings constructed after 1988.

Where do I request Houston CO records from 1972 through 1988?

The Houston Permitting Center Open Records section lists Certificates of Occupancy from 1972 through 1988 among the records it processes.

Does the inspection immediately produce a CO?

Not necessarily. Inspectors may identify corrections and separate permit requirements. The required work and final inspections must be completed before issuance.

How long does an applicant have to complete required corrections?

Current City guidance states that the applicant generally has 180 days to obtain required permits and complete the identified corrections.

Does a Houston CO prove that a business is currently open?

No. A CO documents approved occupancy context. It does not prove current operation, active tenancy, ownership, financial condition, or a current commercial opportunity.

Is a Harris County Certificate of Compliance the same as a Houston CO?

No. They are issued through different jurisdictions and processes. Confirm whether the property is controlled by the City of Houston, Harris County, another municipality, or more than one authority.

How Registry Intelligence structures Houston occupancy signals

City of Houston, Harris County, and other official systems remain the controlling sources for occupancy certificates, permit applications, inspections, plans, compliance documents, and current regulatory procedures.

Registry Intelligence does not replace the Houston Permitting Center, Houston Permit Portal, Occupancy Inspections, Harris County ePermits, public-record requests, direct agency verification, legal review, or professional property due diligence.

The Houston Commercial Intelligence Module structures selected official-source records into a commercial review layer that may combine occupancy and permit context with property and parcel signals, regulated-business activity, transportation and logistics records, healthcare organizations, environmental and compliance-facing records, infrastructure projects, institutional entities, addresses, dates, categories, subtype labels, and source references.

This structure is designed to support B2B account research, market screening, vendor targeting, commercial real estate review, location analysis, risk context, and compliance-facing investigation before the user returns to the controlling government record for final verification.
