Converting Your Tax Lot to a Lot of Record

Converting Your Tax Lot to a Lot of Record

Thinking about renovating your home? If your home is currently recorded with the District of Columbia Recorder of Deeds as a tax lot, the Department of Buildings (DOB) would like to help you save money and make the process easier.

This recordation status limits you, or a future buyer, from being issued permits for home improvement projects.

DOB has recently announced a fee reduction to convert your property to a Lot of Record for the reduced cost of only $100. If you act now, you will save several hundreds of dollars and prevent lengthy delays when it comes time to undertake an improvement project. Please note that this offer will expire on September 30, 2023, so act quickly if you would like to take advantage.


Should you or a future owner undertake a construction project, you can avoid delaying the project for months during the permitting process, saving time and money.

Having a Lot of Record means that the lot has undergone the necessary reviews for property improvements and permitting can occur without those delays. The conversion of the Tax Lot into a Record Lot itself is an improvement of the real property.


Before you begin, please have a copy of the deed for your property and be prepared to provide each owner’s names as they appear on that deed. Once you have this information, you may apply for a subdivision to convert your Tax Lot into a Lot of Record online at On the home page, select:

If you have additional questions, please contact DOB via email, through our online inquiry form, or during normal business hours using the live chat available on or by phone at 202.671-3500, and we will get back to you in three business days or less.
