The City of Annapolis ADU Permit Process
Makara ADU handles this entire process from design to move-in, full turn-key.
- 01
Zoning & Eligibility
Confirm the zone, whether the unit is allowed by right or needs a special exception, and whether the property sits within 1,000 feet of the shoreline. Makara ADU does this free with our property eligibility checker.
- 02
Design & Drawings
Architectural and structural plans to the city's residential code, sized within 850 square feet of livable space for a detached unit and set to the zone's accessory-structure setbacks.
- 03
Building Permits & Build
Building and trades permits from the city; construction proceeds with city inspections along the way.
- 04
Final Inspection & Occupancy
The city's final inspection and certificate of occupancy, then keys in hand, ready to occupy or rent.

City of Annapolis’s ADU Specialists
We don't build everything. We build ADUs. Based in Gaithersburg, we work with local permitting offices every week and know how each jurisdiction's rules shape what can be built.
Local Rules, Known Cold
Every jurisdiction we serve has its own size limits, setbacks, parking and occupancy rules. We track them, and the eligibility checker on this page runs on that same data.
One Contractor, Start to Finish
Architecture, engineering, permits, foundation, framing, MEP, sprinklers, finishes, and the rental license — Makara ADU manages everything under one contract. No coordinating separate architects, engineers, and builders.
Fixed-Price Proposals
We quote your project in full before a shovel goes in the ground. No surprise change orders mid-construction — we plan for lot coverage, stormwater, and utility connections up front.
Built for Aging in Place & Family
Most of our City of Annapolis clients build to keep aging parents or adult children close. We design single-floor, accessible units that work beautifully today and adapt gracefully over time.
ADU Types We Build in the City of Annapolis
Most jurisdictions allow more than one ADU configuration. We help you choose the right one for your lot, your zone and your goals.
Detached Backyard Cottage
A fully independent structure in your backyard with its own entrance, kitchen and bath. The most flexible option, and the one most people picture. Size and placement follow the rules in the table above.
Attached Second Home
Add an attached ADU with its own separate entrance, kitchen, and bath. Makara ADU will collaborate with you to design the space to be functional to meet your needs while creating an aesthetically pleasing space that will add value to your life, family and your home.
Basement and Garage Conversions
Convert an existing garage or basement into a legal, licensed ADU — the most cost-effective path to added living space, and often faster to permit than new construction.
City of Annapolis ADU FAQ
Is there a minimum lot size for an ADU in Annapolis?
No. The zone, the accessory-structure setbacks and, near the water, the Critical Area overlay decide what fits.
How big can an ADU be in Annapolis?
A detached unit may be up to 850 square feet of livable space.
Can I rent out an ADU in Annapolis?
Confirm occupancy and leasing conditions with the city as part of the approval.
Do I need a special exception?
Not in R1, R2, R3, R4, R1-A, R1-B, R3-R or R4-R, where the unit is allowed by right. In other zones an ADU is permitted but must be approved as a special exception.
What is the Critical Area overlay?
The Chesapeake Bay Critical Area rules apply to land within 1,000 feet of tidal waters and add review of lot coverage, stormwater and clearing.
