Builders, developers, architects, engineers, and property owners may request permission from both the Department of Finance and the Department of Buildings to divide (apportion) or merge (combine) lots. Approval depends on several factors including tax and zoning rules. The Department of Finance Tax Map Office is responsible for processing these requests.

If you are not able to complete your transaction online, you can schedule an appointment to visit one of our business to submit documents, request tentative lots, request certified tax maps, or get assistance with the tax map application process.
The Tax Map Unit will accept applications if the parcels in the application have a valid payment plan in good standing. The Tax Map Unit follows the rules governing the Payment Plan Policy.
