Permits Requiring Special Referrals
Certain permits require referral to another department or agency for additional review and approval. The following conditions will trigger additional review:
- Properties in City Historic Districts (CHAP)
- Properties in the Floodplain
- Projects requiring Design Review
- Projects requiring Forest Conservation Review
- Temporary Structure Permits
- Temporary Event Permits
- Minor Privilege
The Information Counter at the One Stop Shop at 417 E. Fayette Street, Room 100 will conduct an initial review of all Baltimore City Permit Applications. They assist customers in filling out permit applications to ensure that application, plans, and other documentation meet the general plans' acceptance requirements. They will also let applicants know if permits require additional review.
Properties in City Historic Districts – Commission for Historical and Architectural Preservation (CHAP)
In general, exterior modifications and improvements require the review and approval of the Commission for Historical and Architectural Preservation (CHAP). Your permit will not be issued over the counter. Your permit application will be referred to CHAP, and you must obtain a Notice-To-Proceed from them in order for your permit to be issued. Please note that some minor work that would not otherwise require a permit will require one in a CHAP district.
For more information please visit the CHAP website or contact CHAP at 410-396-4866.
Properties in the Floodplain
Locating Your Property on the Flood Map
The Federal Emergency Management Agency (FEMA) produces Flood Insurance Rate Maps (FIRMs), allowing citizens to identify areas that are at risk for flooding. Check here to see if your property is in the floodplain.
If a property is in the floodplain, it triggers floodplain review and the permit is sent to the Department of Planning Floodplain managers. To learn more about requirements, visit the Floodplain Management Homepage.
Baltimore City’s Floodplain regulations supersede both State and Federal floodplain regulations. The Office of Sustainability has created a dedicated page for all necessary forms and permits. Visit the Permits & Forms page to download the necessary paperwork.

Zoning does an initial review of the project for compliance with the Zoning Ordinance of Baltimore City before plans are submitted. They will either give approval at that time or accept the project for "filing only" and reserve approval pending the resolution of certain questions.
In the case of a zoning violation, a zoning appeal would be required. A zoning appeal is a formal process heard before the Zoning Board on a specific scheduled date.
Upon completion of their review, Zoning provides a number and sends the applicant to Office Services within the One Stop Shop Center.
Please see the Office of the Zoning Administrator page for more information.
