Home Additions in Annapolis
An addition is the one project where zoning can stop you before design starts. We are a licensed contractor in Maryland (MHIC #111971) — we pull the permits through the Anne Arundel County Department of Inspections and Permits, coordinate the licensed trades, and hand you a written line-item scope before demolition starts.

- A written, line-item scope for your Annapolis project before anyone swings a hammer
- Permits pulled through the Anne Arundel County Department of Inspections and Permits under MHIC #111971
- One project manager from demolition to final walkthrough
Two fields and one question. A specialist calls you back to confirm a time.
The paperwork is the part most contractors gloss over.
An addition starts with zoning, not construction: setbacks, lot coverage and height limits get reviewed before a building permit is issued, and in some neighborhoods there is a stormwater or historic review on top. Then come the footing and foundation inspections, which have to pass before backfill. This is the longest-lead permit of any project we do, and it is why we start the paperwork while the design is still being drawn.
Your Annapolis permit goes through the Anne Arundel County Department of Inspections and Permits. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.
The City of Annapolis issues its own permits for properties inside the city, and the historic district adds a preservation review for exterior changes. Outside the city limits, permits go through Anne Arundel County instead. Which applies to you is the first thing we confirm.
The house decides half the scope.
Annapolis ranges from 18th- and 19th-century houses downtown to mid-century and newer housing outside the historic district. Downtown, expect masonry, plaster and structural surprises; the written scope after the walkthrough is the only number worth planning around.
What's included- ✓Zoning, setback and lot-coverage review before design is finalized

Legitimately excellent. If your roof qualifies to be replaced due to storm damage, go with United Developers. Anthony was with me every step of the way — through the claims process and after the install.

How long does an addition actually take?
The build is rarely the long part — permitting and zoning review are.

We will tell you at the walkthrough if your lot has a setback or coverage problem, because that changes the whole conversation.
