Applying for a Certificate of Occupancy includes 6 steps:

1. Property Address

2. Applicant Validation

3. Existing CofO

4. Building Description

5. Permits

6. Summary and Submission

Each step is dependent on the preceding one, meaning that the next step will only become accessible if you complete the previous step:

• provided all the required data, and
• saved all the subsections of the preceding step.

Follow the specific order of steps above and the form guides you through the process.

The system will define the list of required documents based on the information you provide. In the final step (Step 6), ensure that you upload all the required documents necessary for the application.

Enter the address information for the property on which you wish to make changes.

1. Complete the required fields of the 'Property Address' form.

2. Click on 'Search.'

All fields are required by default; you must enter data to proceed unless specific fields are marked as 'if applicable' or 'optional.'

3. Find and select the correct address you want to use for the CofO. When you select an address, you will be able to see the name of the owner(s) and their addresses as well.

If you see more addresses in the list and it is difficult to choose, you can narrow down the search results by providing a unit number.

IMPORTANT: Ensure that you choose the accurate address, owner name, and owner address before proceeding, as the information selected in this step will be displayed on the final CofO.

Contact DOB if you have any questions (e.g., you can't find the address because it is a freshly purchased property and it is not updated in the database yet) or something is unclear about the addresses.
