88% of home buyers have at least one inspection before purchasing, while the remaining 12% have none. Buyers want reassurance that a home is safe, functional, and ready to live in.
This is where a Certificate of Occupancy can make a difference. The document confirms that a property meets local building and safety requirements and can be legally occupied.
For sellers, having a valid CO can help build buyer confidence and reduce potential concerns during the transaction. For buyers, it provides an extra layer of assurance that the property has met key safety standards.
What Is a Certificate of Occupancy?
About 1 in 5 real estate closings gets delayed, often over paperwork issues. A certificate of occupancy is one document that can hold up your closing if it’s missing or outdated.
Certificate of Occupancy Meaning
A Certificate of Occupancy is an official document issued by your local government. It confirms that a building meets safety requirements and can be legally occupied. It also shows that the property was built in accordance with approved plans and local building codes.
Think of it as the final approval a property receives before people can move in. Local governments require a CO to help ensure homes are safe for occupants. A property cannot be legally occupied until a valid Certificate of Occupancy has been issued.
What Information Does a Certificate of Occupancy Include?
A CO lists important details about the property and clearly states how occupants can legally use the building.
Every official certificate includes the following:
- The property’s street address and official city parcel number
- The building type, such as a single-family home or a multi-family apartment
- The maximum number of people allowed to live in the home at one time
- The city inspector’s signature confirming the property passed inspection
Why Is a Certificate of Occupancy Important?
For buyers, most lenders require a CO before they approve a mortgage. Insurance companies may also request it before issuing coverage. It confirms that the city has inspected the home’s structure, electrical system, plumbing, and fire safety and approved it for occupancy.
For sellers, a CO confirms that the property meets local building and safety requirements for legal occupancy. If one is missing, the seller may need to complete inspections or address code issues before closing. Getting this sorted early can help prevent delays or complications during the sale.
When Is a Certificate of Occupancy Issued?
You need to apply for a Certificate of Occupancy in the following situations:
- New construction
- Change of use
- Major structural changes
- Significant renovations
- Reoccupation after safety issues
It’s important to note that sellers must provide the Certificate of Occupancy to the buyer at the time of sale, even if none of the above conditions apply.
Who Is Responsible for Certificate of Occupancy?
When you build a house from scratch, the licensed general contractor applies for the certificate of occupancy. They take care of this administrative step before finishing the construction work.
If the house is older and being renovated, the current homeowner or developer applies. In some cases, the hired architect submits the paperwork to the city hall on the owner’s behalf.
Who Issues Occupancy Certificate?
A Certificate of Occupancy is issued by the local building department or building authority in the city, town, or county where your property is located.
For example, if you build a new home in Dallas, Texas, the city’s building department would inspect the property and issue the Certificate of Occupancy once it meets local building and safety requirements.
How Much Does a Certificate of Occupancy Cost?
The cost of a Certificate of Occupancy varies by city and the type of CO required. Here’s what sellers can expect in five major U.S. housing markets based on current city fee schedules:
| Housing Market | Certificate of Occupancy Cost |
|---|---|
| New York City | $130 for an initial CO or renewal without changes |
| Los Angeles | $150 for a CO for use of land; other CO fees can vary |
| Houston | $537.12 base charge for an existing building, plus additional fees in some cases |
| Phoenix | No additional charge when issued after required construction; temporary or partial COs cost $780 |
| Chicago | Varies by project and permit type |
These are not universal rates for every property. The final cost can change based on the type of property, required inspections, changes in occupancy, and whether additional permits or reviews are needed.
How Long Does It Take to Get an Occupancy Certificate?
The time to obtain a Certificate of Occupancy can range from a few days to several weeks, depending on the property and local requirements. A straightforward application may be processed quickly, while required inspections or unresolved code issues can extend the timeline.
For newly built or renovated homes, the building department may require multiple inspections before issuing the CO. Sellers can avoid delays by checking for open permits, completing required repairs, and confirming the documents needed before submitting the application.
Is a Certificate of Occupancy Mandatory in Your State?
Some states have strict rules, whereas others have flexible rules about having a CO. Moreover, the city you are in might have a different set of regulations than your state too.

How to Get a Certificate of Occupancy: 4 Steps
You must follow these four steps to get a CO. The exact process varies by location, but most building departments require an application, property inspection, and approval before issuing the certificate.

- Contact Local Authorities: Start by contacting the city or county office that issues Certificates of Occupancy. They can explain the local requirements, application process, and any fees that may apply.
- Fill out the Application: Then, fill out the required application form. Many cities allow you to apply online, while others require paper forms or in-person submissions.
- Prepare the Documents: Prepare any CO paperwork the local authority requires. These may include building permits, approved plans, inspection records, and proof that the property meets local building and safety codes.
- Complete the Submission Process: Submit your application with supporting documents. If inspections are required, schedule them with the local building department. Once the property passes all required inspections, the Certificate of Occupancy can be issued.
Certificate of Occupancy Requirements
The paperwork requirements for a Certificate of Occupancy vary from state to state. If you have built your home from scratch, you will need:
- Project Commencement Certificate: This certificate marks the start of any new building project. It confirms that the project has all the necessary permissions and approvals.
- Project Completion Certificate: It implies that the project is complete as per plans. This certificate states that the builder has followed building rules.
- NOC for Fire and Safety: This certifies that the property follows fire and safety regulations.
Other Documents:
As a homeowner, you may need to submit the following documents –
- Proof of ownership

- Final structural, plumbing, electrical, and mechanical inspection sign-offs
- Fire safety certificate
- Proof of water, sewer, and electricity connection

How to Check CO Status?
If you’re buying an older home, check whether a Certificate of Occupancy is on file before closing. Start with your county or city’s property records website and search by the property address; some jurisdictions provide permit and occupancy records online.
If the records are not available online, contact the local building or permitting department and ask how to access the property’s permit history.
For example, in New York City, you can use the Department of Buildings’ BIS or DOB NOW system to search a property by its address and view its Certificate of Occupancy and other building records.
What Happens If a Property Has No CO?
Living in a house without this paper can cause problems. Depending on local rules, it can lead to legal, financial, or selling issues.
What Are the Legal Consequences?
In some areas, the city can fine you if you live in a home without the required approvals or if it breaks building rules. If the home is unsafe, the city can also ask you to fix the problems before you live there.
What Are the Financial Risks?
Home insurance does not depend only on this document. However, if the home has unapproved or unsafe work, it can create issues during insurance claims or approvals.
What Are the Resale Challenges?
Selling a home without a Certificate of Occupancy can be harder. Buyers or banks may ask for it, and this can delay the sale until you provide it.
The current owner is generally responsible for legal, financial, and property-related issues caused by a missing CO. If the property is being sold, the seller typically handles outstanding CO or permit issues unless the purchase agreement assigns them to the buyer. If you can’t get a CO immediately, try getting a temporary CO for the meantime.
What Is a Temporary Certificate of Occupancy?
A temporary occupation permit is a document you receive when your home has minor issues that do not pose a direct threat to the occupants’ lives. These issues are non-structural, like pending interior decoration work or unfinished landscaping.
The TCO is valid for 90 days. In some states, you must reapply after every 30 days during that period. You cannot extend the validity of a TCO beyond 90 days.

What Is a CO Inspection?
The local authorities conduct a CO inspection of your home’s structure and functions. You can’t legally occupy a home unless the inspection report states that it is safe to live in.
If your home includes things that fail a home inspection, you might have to repair or renovate it until it becomes safe to occupy. If the house doesn’t pass the CO inspection, you will not be able to stay in the house.
What Does the Inspector Examine?
- Structural Integrity: The foundation inspection determines whether the framework, foundation, and stability of your home are sound enough to sustain occupancy.
- Plumbing System: To maintain health and safety standards, a plumbing inspection checks for the proper installation of the pipe system and prevention of leakage. The inspection covers the supply of potable water too.
- Electrical Wiring: Inspectors check if the installation and grounding of all electrical systems adhere to the codes of fire safety. Electrical inspections aim to ensure that electrical fires and shock hazards can be avoided.
- Fire Safety: The inspection checks if the fire safety measures like smoke alarms, fire exits, and sprinkler systems work properly.
The inspectors can further conduct a roof inspection or an HVAC inspection. However, these parameters may vary depending on the location of your home.
Is a Certificate of Occupancy Really Important?
