Home Additions · Frederick
Why Frederick homeowners hire us.
A Frederick addition on a parcel inside the city is filed with City of Frederick Building and Permits, in the public works department.
The city lists Residential Addition as its own building and zoning application, separate from the deck and porch application and separate from interior renovations and finished basements.
Pricing for a Frederick addition is a free written estimate after a site walk of the parcel.
For this area, see Permits in Frederick County: what to expect.

Questions about home additions in Frederick
Which code applies to a Frederick addition applied for after 2025?+
For a permit applied for after December 31, 2025, the 2021 International Residential Code applies together with the Maryland Building Performance Standards. The city dates that change to January 1, 2026 and pairs the 2021 International Building Code and the 2021 energy code with it. The plumbing-code edition in the next city note is a different code and is not substituted here.
Can a Frederick addition use the Tuesday one-stop counter?+
The in-person counter runs on Tuesdays from 8 until 11 at 140 West Patrick Street. Its published eligible list includes residential decks and porches, and basement finishes that do not create a new dwelling unit. Residential additions are absent from that list, so a Frederick addition does not use that counter. Someone who does use the counter for an eligible project is told not to start an online application as well.
Where are Frederick addition applications and payments accepted?+
The municipal annex is open to the public from 8 until 2 on weekdays. Applications and card payments can go through the city OpenGov portal, and in-person payments during those annex hours are the other path the city names. A payment instruction that arrives by email is not how the city collects a permit fee.
