The Local Building Department Issues Your Occupancy Certificate

An occupancy certificate (also called a certificate of occupancy or CO) is issued by your city or county building department, not by the contractor, architect, or property owner. The building department is the government office that enforces construction codes and safety rules in your area. Once a building passes final inspection, that department issues the certificate that says the structure is safe to occupy.

The specific department name varies by location. In some places it is called the Building Department, in others the Department of Buildings, Code Enforcement, or Permits and Inspections. Regardless of the name, it is always a local government agency—either city or county level—not a state or federal office.

You cannot get an occupancy certificate without passing inspection. The building department sends an inspector to verify that the completed structure meets all applicable building codes, fire codes, electrical codes, and plumbing codes. Only after that inspection passes does the department issue the certificate.

Key Takeaways

  • Your city or county building department is the only body that can issue an occupancy certificate; no private company or contractor can issue one.
  • The building department must conduct a final inspection and confirm the structure meets all applicable codes before issuing the certificate.
  • You need a valid occupancy certificate before you can legally move into a new building or occupy a space after major renovation.
  • The building department keeps records of issued certificates, and you can request a copy if you have lost the original.
  • Different jurisdictions may have different names for the same office, so contact your local government's main line if you are unsure which department handles building permits.

How the Building Department Decides When to Issue One

The building department does not issue an occupancy certificate on a schedule or timeline you control. Instead, the certificate is issued only after the contractor or builder requests a final inspection and that inspection passes. The contractor typically requests the inspection once they believe all work is complete and the building meets code.

The inspector will check items like structural integrity, electrical systems, plumbing, fire safety equipment, egress routes (exits), and any other systems required by local code. If violations are found, the inspector issues a list of corrections needed. The contractor must fix those items and request another inspection. This cycle repeats until the building passes.

Once the inspection passes, the building department issues the certificate. The timeline from final inspection request to certificate issuance is usually one to four weeks, depending on how busy the department is and whether corrections were needed.

What Happens If You Occupy a Building Without One

Occupying a building without a valid occupancy certificate is illegal in most jurisdictions. The consequences can include fines against the property owner, orders to vacate, or both. Insurance may also refuse to cover damage or liability in an unoccupied building, leaving you personally liable for injuries or losses.

If you are renting a space, the landlord is responsible for obtaining the certificate before you move in. If you are buying a property, the seller should provide proof of a valid certificate. If neither has one and the building has been substantially renovated or newly constructed, you should not move in until the certificate is issued.

Getting a Copy of an Occupancy Certificate

If you own or rent a property and need a copy of the occupancy certificate, contact the building department that issued it. You will need the property address and possibly the parcel number (found on your property tax bill or deed). Most building departments maintain searchable records online or will provide a copy by mail or in person for a small fee, usually under twenty dollars.

Some departments allow you to search their records on a public website without calling. Others require you to visit in person or submit a written request. Call your local building department's main number and ask how to obtain a copy of the certificate for your address.

If the building is very old, the original certificate may not be in the department's digital system. In that case, the department may issue a letter stating that the building was permitted and inspected under the codes in effect at the time of construction, which serves the same purpose for most transactions.

Different Types of Occupancy Certificates

Some building departments issue a temporary occupancy certificate (also called a temporary CO or TCO) before all work is completely finished. This allows partial occupancy of a building while final details are still being completed. A temporary certificate is valid for a set period—often 30 to 90 days—and requires the contractor to finish the remaining work within that time.

A final occupancy certificate is issued once all work is done and all inspections pass. This is the permanent certificate and has no expiration date (though it can be revoked if the building is later found to violate code).

Some jurisdictions also issue partial occupancy certificates for large buildings where different sections can be occupied at different times. For example, a multi-unit apartment building might receive a partial certificate for the first ten units while the remaining units are still under construction.

Who Requests the Inspection and Certificate

The property owner or their contractor is responsible for requesting the final inspection from the building department. The owner cannot force the department to issue a certificate—the certificate is only issued after inspection confirms the building meets code. However, the owner can contact the building department to schedule the inspection once they believe construction is complete.

If you are buying a property and the seller claims to have an occupancy certificate, ask to see it. If the seller cannot produce one and the building was recently constructed or heavily renovated, do not close on the purchase until the certificate is obtained and verified with the building department.

Frequently Asked Questions

Can a contractor or architect issue an occupancy certificate?

No. Only the local building department can issue an occupancy certificate. A contractor or architect may prepare the building for inspection and request the inspection, but they cannot issue the certificate themselves. If someone claims to issue a certificate outside the building department, it is not valid.

What if the building department lost my certificate?

Contact the building department and request a certified copy. Most departments keep records for decades and can issue a duplicate. You may need to provide the property address and construction date. There is usually a small fee for a certified copy, typically under thirty dollars.

Can an occupancy certificate be revoked?

Yes. If the building department later discovers that the building violates code or that unsafe conditions exist, the certificate can be revoked. This is rare but can happen if major structural damage occurs or if the building is used in a way that violates the original permit (for example, converting a residential building to commercial use without approval).

Do I need an occupancy certificate if I am just renovating one room?

It depends on the scope of work. Minor repairs and cosmetic updates usually do not require a permit or certificate. However, if you are doing structural work, adding electrical outlets, moving walls, or changing the use of a space, you typically need a permit and a final inspection. Contact your local building department to ask whether your specific project requires a permit.

How long does it take to get an occupancy certificate?

The timeline depends on how busy the building department is and whether the building passes inspection on the first try. From the time you request a final inspection to receiving the certificate usually takes one to four weeks. If corrections are needed, add one to two weeks for each round of fixes and re-inspection.
