Find a California Certificate of Occupancy Without Searching the Wrong Database
A California certificate of occupancy is usually maintained by the city or county building department that issued the underlying building permit. There is no single statewide public search that replaces every local building-record system, so the key is identifying the correct jurisdiction first.
Where to Start a California Certificate of Occupancy Search
The first task is not finding a statewide certificate database. It is identifying the government agency responsible for the property. California cities commonly operate their own building departments, while unincorporated areas are often served by a county building or planning department.
A mailing address can be misleading. A property described as being in a familiar city may actually lie in an unincorporated area or another municipality. Before concluding that a certificate is missing, confirm the permitting jurisdiction.
Search the city building department
Look for building records, permit history, property records, certificate records, or a records-request service.
Search the county building authority
The county may maintain the permit and occupancy history instead of the nearest city’s building department.
Confirm the parcel first
Use official assessor, city boundary, planning, or property information before choosing a permit portal.
Start with the exact property address. If the local portal does not return a clear match, add the assessor parcel number or a known building permit number. Historical addresses and earlier permit identifiers can be useful for older structures.
What a Certificate of Occupancy Actually Tells You
A certificate of occupancy, often shortened to CO or C of O, is associated with approval to occupy a building or portion of a building for an identified use when the applicable building authority requires such a certificate.
The certificate is generally connected to the building permit and inspection process. It can identify the approved occupancy or use, building address, permit information, and other information required by the applicable code and local procedure.
What a CO can help establish
- That an occupancy approval was issued for the building or space described on the certificate.
- The approved use or occupancy classification shown on that record.
- A connection between the occupancy approval and a building permit or completed project.
- Whether a permanent or temporary occupancy document was issued, where the jurisdiction distinguishes them.
What a CO does not automatically prove
- That every later alteration to the property was permitted.
- That every room, unit, conversion, accessory structure, or remodel visible today appears on the certificate.
- That zoning, business licensing, fire permits, health permits, or other approvals are current.
- That an old certificate reflects changes made after its issuance.
- That the property has no open permits, violations, or unresolved inspections.
A certificate showing that a building was approved for one type of occupancy years ago does not necessarily document a later interior remodel or tenant-specific use. Search the later permit and inspection history as well as the occupancy record.
How to Look Up a California Certificate of Occupancy
The exact interface varies by jurisdiction, but the research sequence is similar across California. Use these steps before filing a broad public-records request.
Confirm the governing jurisdiction
Determine whether the address is inside an incorporated city or an unincorporated county area. Use the building department responsible for that location rather than assuming the county name determines the record holder.
Gather property identifiers
Have the street address, assessor parcel number, approximate construction or remodel date, and any known permit or project number available.
Open the official building-record portal
Look for a government service labeled permit search, building records, property records, document search, permit history, records request, or certificates of occupancy.
Search the property before searching only for “CO”
Many systems index the document under a building permit, project, property address, or archival record instead of providing a separate certificate search screen.
Review permit and inspection history
Identify major construction, additions, tenant improvements, or changes in use. Check whether the relevant permit reached final approval rather than stopping at permit issuance.
Open or request the actual certificate
If a scanned certificate is available, review it directly. If the portal lists a record but not the document, follow the building department’s records-request procedure.
Ask the issuing department when the record is unclear
If the certificate cannot be found, the property use has changed, or the historical record conflicts with the current building, ask the responsible building authority what record establishes the approved occupancy.
Official California Lookup Examples by Jurisdiction
California jurisdictions do not all use the same terminology or records system. The examples below show why a California-wide search often becomes a local building-department search.
| Jurisdiction | Record approach | Useful starting point |
|---|---|---|
| City of Los Angeles | LADBS provides online building-record services and a records process for documents not available through the online system. | LADBS Online Building Records |
| San Francisco | The Department of Building Inspection records system includes Certificate of Final Completion and Certificate of Final Completion and Occupancy records. | SF DBI Records Request |
| City of San Diego | Development Services publishes a dedicated Certificate of Occupancy bulletin covering issuance, temporary occupancy, existing-building requests, and missing original certificates. | San Diego Information Bulletin 585 |
| City of Sacramento | The Building Division publishes separate guidance for Certificates of Occupancy and Temporary Certificates of Occupancy and provides a public permit portal for record status. | Sacramento Certificates of Occupancy |
If you are researching a Los Angeles property, our LADBS permit search guide explains the City’s building-record systems in more detail. The separate Los Angeles building permit search guide is useful when you first need to identify permits and inspections connected to the address.
Certificate of Occupancy vs. Permit, Final Inspection, and Related Records
Building-record searches can return several documents that sound similar but answer different questions. Treat them as related records rather than interchangeable proof.
Building permit
Authorizes a defined scope of construction work, subject to applicable conditions and required inspections. Issuance alone does not prove completion.
Final inspection
Indicates the applicable inspection process reached a final approval for the permit or work being inspected. Confirm the exact permit and scope.
Certificate of occupancy
Documents approval for occupancy of a building or space when the jurisdiction requires the certificate for that project and use.
Temporary certificate of occupancy
Allows limited or conditional occupancy before full project completion when the building official determines applicable safety requirements are satisfied.
Other names you may encounter
Local terminology can differ. San Francisco, for example, uses records titled Certificate of Final Completion and Certificate of Final Completion and Occupancy. When searching an older property, use the terminology used by that jurisdiction instead of searching only for the phrase “certificate of occupancy.”
How to Find Older or Historical Occupancy Records
Historical certificates are often harder to locate than current permits because older documents may have been created on paper, microfilm, or legacy database systems. Some may be indexed by permit number rather than the modern street address.
Try these identifiers in order
- Current street address. Start with the official address used by the local jurisdiction.
- Assessor parcel number. This can help when a street address has changed or a parcel has several associated addresses.
- Building permit number. If a permit produced the occupancy approval, its number may lead directly to the underlying certificate.
- Historical address. Older structures may have been renumbered or recorded under another address format.
- Approximate construction or change-of-use date. Records staff can often search more effectively when you provide a reasonable time period.
San Francisco’s public records-request system lists Certificate of Final Completion / Certificate of Final Completion and Occupancy records as an available category. This is a useful reminder that older California occupancy records may be filed under a locally specific document name.
If the scan is not available online
Use the responsible building department’s formal records process. Describe the document you need rather than requesting “all records” unless a broad request is genuinely necessary. Include the property address, parcel number, permit number, project name if known, and approximate date.
Building plans can be subject to separate access and reproduction rules. The fact that a permit or certificate is publicly indexed does not mean every plan sheet or architectural drawing can automatically be downloaded.
What to Do If You Cannot Find a Certificate of Occupancy
A missing online certificate does not by itself prove that the building lacks legal occupancy approval. The correct next step depends on why the document is missing.
| Problem | Possible explanation | Next action |
|---|---|---|
| No result for the address | Wrong jurisdiction, address formatting, historical address, or incomplete indexing. | Confirm jurisdiction and parcel number; retry using the permit or APN. |
| Permit exists but no CO appears | The project may not have required a separate CO, may not have reached final approval, or the certificate may be stored separately. | Check final inspections and ask the building department what closeout document applies. |
| Very old property | Records may predate current electronic systems or use another certificate name. | Request archival research using the approximate construction date and historical identifiers. |
| Current use differs from old records | Later alterations or changes in occupancy may have occurred. | Search subsequent permits, change-of-use records, and final approvals. |
| Department cannot locate an original | The original record may be unavailable or never created for that building type. | Ask what current process establishes lawful occupancy for the specific property. |
Do not create a conclusion from one empty search screen
Property records are distributed across different systems. A building-permit database, planning case system, code-enforcement database, scanned document archive, and records office may each contain different parts of the history.
If the issue matters for a sale, lease, loan, insurance decision, business opening, or construction project, obtain clarification from the issuing authority rather than treating an unsuccessful online search as a legal determination.
Using Occupancy Records for California Property Due Diligence
Buyers, tenants, property owners, lenders, and design professionals often search certificates because they need to understand the approved use of a building. A useful review goes beyond locating one document.
Property-record checklist
- Confirm the legal property and parcel you are researching.
- Identify the responsible city or county building authority.
- Search major building permits, especially additions and conversions.
- Review available final inspection information.
- Locate the applicable occupancy or completion certificate when one was required.
- Compare the approved use with the property’s current advertised use.
- Look for later tenant improvements or changes in occupancy classification.
- Check for unresolved permits or code-enforcement issues when relevant.
- Review zoning separately when the proposed use matters.
- Ask the building department or a qualified professional about unresolved discrepancies.
If a property advertisement describes an extra dwelling unit, an old certificate for the original building does not automatically establish that the later unit was approved. Search for the permit, inspections, and final approval associated with the conversion or addition.
A certificate showing one historical occupancy does not necessarily authorize a materially different proposed use. Check current zoning, building occupancy requirements, tenant-improvement permits, fire or life-safety requirements, and any business-specific approvals before relying on the old certificate.
Temporary Certificates of Occupancy in California
A Temporary Certificate of Occupancy, commonly called a TCO, may allow a building or a defined portion of a project to be occupied before every element of the project is fully complete. It is not the same as permanent project closeout.
Local building officials decide whether temporary occupancy is appropriate under their applicable code and procedures. Requirements may include completed life-safety work, approvals from multiple inspection disciplines, defined areas of occupancy, and an expiration or limited validity period.
When a TCO appears in records
- Phased commercial construction.
- Large projects where one portion is ready before another.
- Limited stocking, employee training, or other controlled occupancy where locally permitted.
- Projects awaiting non-life-safety completion items that the building official allows to remain outstanding.
Do not treat an expired or temporary certificate as a permanent certificate. If a property record shows a TCO but no later permanent occupancy document, review subsequent inspections and contact the building department to determine the final project status.
California Building Code and Local Jurisdiction Rules
California’s statewide building standards are published in Title 24 of the California Code of Regulations. The 2025 California Building Standards Code became effective January 1, 2026. Local jurisdictions administer and enforce building requirements within their authority and may also have properly adopted local amendments.
For a certificate lookup, this distinction matters because the statewide code provides the regulatory framework while the local building official normally controls the actual permit, inspection, and occupancy record.
California Building Standards Commission
Use the Commission’s official code page to identify the current Title 24 edition and related code publications.

The Commission publishes jurisdictional ordinance filings for amendments to the 2025 edition of Title 24.

Frequently Asked Questions About California Certificate of Occupancy Records
Is there a statewide California certificate of occupancy lookup?
There is no single public statewide search that replaces every city and county building-record system. Start with the building department responsible for the property’s jurisdiction.
Can I search for a certificate of occupancy by address?
Often, yes. Many local building-record systems support address searches. If the address produces incomplete results, try the assessor parcel number, permit number, or another official property identifier.
Does every California house have a certificate of occupancy?
No. Issuance practices vary by jurisdiction, building type, project type, and age of the structure. Some California cities specifically state that they do not issue separate certificates for certain residential structures.
Is a finaled building permit the same as a certificate of occupancy?
Not necessarily. A finaled permit and an occupancy certificate are related but distinct records. The local jurisdiction determines which closeout and occupancy documents apply to the project.
Can I get a copy of an old certificate of occupancy?
Potentially. Search the local building department’s archive or records portal first. If the document is not digitized, submit a targeted records request with the address, parcel number, approximate date, and any known permit number.
What if the city cannot find the original certificate?
Ask the building department what process applies to the specific property. The department may rely on historical permits, final inspection records, an existing-building occupancy process, or another locally defined procedure.
Does a certificate of occupancy prove that all later remodeling was permitted?
No. A certificate documents the building or space covered at the time it was issued. Later additions, conversions, tenant improvements, or other alterations should be researched separately.
Can a temporary certificate of occupancy be used as permanent approval?
No. A TCO is temporary and may contain conditions, a limited scope, or an expiration period. Check whether a permanent certificate or final project approval was later issued.
What information should I provide when requesting a CO record?
Provide the complete property address, assessor parcel number when available, permit or project number, approximate construction or completion date, and a clear description of the certificate or occupancy information you need.
Who should I contact if a property’s current use conflicts with the occupancy record?
Contact the city or county building department responsible for the property. Depending on the issue, planning, zoning, fire prevention, code enforcement, or a qualified design or legal professional may also need to be consulted.
