Anne Arundel County's Department of Inspections and Permits at 2664 Riva Road in Annapolis permits and inspects construction across 588 square miles with more than 25 certified inspectors, and the overlay that shapes its work is the Chesapeake Bay Critical Area: the land within 1,000 feet landward of mean high tide or the edge of tidal wetlands as shown on the state tidal wetland maps, along with the waters of the Bay and its tributaries. A grading application inside it carries a Critical Area worksheet detailing existing and proposed lot coverage and impervious cover, and exemptions that apply elsewhere in the county — small detached decks, gazebos and the like — stop applying inside it.
The county files through the Land Use Navigator portal, where applicants create an account, select the record type, enter contacts, upload PDF documents and schedule inspections. The inspection rules are exact: a permit must be active for 24 hours before the first inspection can be requested, all associated trade permits must have passed their final inspections before the final building inspection is scheduled, and on commercial and tenant improvement permits the fire marshal's final must be passed first.
This guide covers Anne Arundel County outside the City of Annapolis, which runs its own permit office. Communities such as Glen Burnie, Severna Park, Pasadena and Odenton are unincorporated and permitted by the county.
The Critical Area redraws the exemptions. Anne Arundel's exemption list is written twice — once for the county and once for the shoreline. Detached decks under 200 square feet and under 3 feet high, and gazebos up to 150 square feet and 10 feet high, are exempt only outside the Critical Area and the Bog Contribution Drainage Area. Inside them, the same structure needs the permit and the Critical Area worksheet with its lot coverage and impervious figures.

Typically permit required
- Any work inside the Chesapeake Bay Critical Area, which needs the Critical Area worksheet with existing and proposed lot coverage and impervious cover
- Grading, which takes its own permit and may be required even where the structure itself is exempt
- Trade work — mechanical, plumbing and electrical — which needs separate permits and county-licensed tradesmen
- New buildings, additions and any structural work on an existing building
- Interior alterations that reconfigure space, add plumbing fixtures or extend circuits, under the building or residential code and the Maryland Building Rehabilitation Code
- Decks, accessory structures above the local exemption threshold, retaining walls and swimming pools, including above-ground pools
Often exempt
- Residential patios, detached decks under 200 square feet and under 3 feet high, and gazebos up to 150 square feet and 10 feet high — outside the Critical Area and Bog Contribution Drainage Area only
- Painting, wallpapering, interior finishes, cabinets, flooring and trim
- Like-for-like replacement of windows and doors in the same opening
- Small detached accessory structures below the jurisdiction's exemption threshold and fences below its height limit — the zoning rules still apply
- Minor repairs that do not remove or alter structural members
What is actually local, and what is not
The code editions are the state's. Anne Arundel County's layer is the enforcing office and its amendments to the building and residential codes, its fee schedule, its grading ordinance and its stormwater programme under MDE criteria, and the Chesapeake Bay Critical Area and the Bog Contribution Drainage Area, which decide what is exempt long before the building code does.
Maryland enforces one statewide set of codes, the Maryland Building Performance Standards (COMAR 09.12.51), through the county or city permit office, which may amend the building and residential codes for local conditions. Maryland rules

Permit types
Residential permits
An Anne Arundel house project starts with the county’s own guidance on whether a permit is needed, then files in the Land Use Navigator with parcel information including zoning, floodplain, Critical Area and bog conditions. Homeowners may apply for ordinary repairs or construction on their own owner-occupied dwelling. Electrical, mechanical and plumbing work needs separate trade permits, and the county requires that work to be done by tradesmen licensed in Anne Arundel County. Plumbing groundwork is inspected before the floor closes, and insulation after framing but before drywall.
Commercial permits
Commercial and tenant improvement work in Anne Arundel County is valuation-based on the fee schedule and reviewed against the county building code, with grading, stormwater, Critical Area and right-of-way approvals running alongside. The fire marshal's final inspection must pass before the final building inspection is scheduled, and each trade is inspected by its own inspector rather than on a single visit.
Prior approvals, plan review and the local clock
In Anne Arundel County the Chesapeake Bay Critical Area reaches 1,000 feet inland from tidal water, the Bog Contribution Drainage Areas add their own restrictions, and shoreline stabilisation work brings state waterway and wetland permits into the file. Maryland sets no deadline for deciding a building permit (though since 1 October 2026 the office must decide within 30 days whether a housing application is complete) — Anne Arundel County publishes its own targets, and they are the number to plan against.
Maryland licenses home improvement contractors through the Maryland Home Improvement Commission and home builders register with the Attorney General; trade licences are mostly state licences, but some counties and WSSC license or register trades themselves. Maryland rules

Fees follow the county's schedule, valuation-based for general building permits, with the county directing applicants to the Land Use Navigator to calculate the cost of a specific application.
| Item | Fee or rule |
|---|---|
| Building permit | $43 non-refundable application fee plus a fee on estimated value: $86 up to $3,000, rising to $242 at $25,000, then $242 plus 1% of the value above $25,000; the portal calculates the figure for a given application |
| Reinspection | $150 where a scheduled inspection is not cancelled at least 24 hours ahead or the job is inaccessible |
| Grading permit | Separate application, with a Critical Area worksheet where the site is inside the Critical Area |
| Trade permits | Separate mechanical, plumbing and electrical permits, pulled by tradesmen licensed in Anne Arundel County |
| First inspection | Not available until the permit has been active for 24 hours |
| Fire marshal | Final inspection required on commercial and tenant improvement permits before the building final |
A missed inspection is billed. Anne Arundel charges a $150 reinspection fee where a scheduled inspection is not cancelled at least 24 hours in advance or the job is inaccessible when the inspector arrives. With separate inspectors for each trade and no guarantee they arrive together, the 24-hour cancellation rule is the one to diary.

How to apply for an Anne Arundel County building permit
Zoning certification, grading and sediment control, stormwater, forest conservation and Critical Area review run ahead of the building permit.
The home builder registration number (required by state law for new homes) or, where the office asks for it, the Maryland Home Improvement Commission licence number goes on the application.
The local application with the building, residential and energy code submittals the scope requires, and trade permits alongside.
Reviewers in the local office check the building, residential and energy codes as the jurisdiction amended them; corrections are answered in writing.
Fees follow the jurisdiction's ordinance and are due before issuance.
Footing to final by permit number, then the use and occupancy certificate that closes the permit.
Review, corrections and what actually causes delay
Anne Arundel County reviews through the Land Use Navigator, where the record type chosen at the start determines what the portal asks for. What delays a file here is a Critical Area worksheet omitted on a shoreline parcel, an exemption claimed from the general list on a parcel inside the Critical Area, and a final building inspection requested before the trades and the fire marshal have passed theirs.

Inspections follow the adopted codes' required sequence — footing, foundation, framing, rough trades, insulation and final — and are requested from the local office by permit number. Work that passes final receives a use and occupancy certificate for new buildings and changes of use, or a final approval on the permit for everything else. Anne Arundel County schedules inspections through the Land Use Navigator or by telephone, with the permit active for 24 hours first; trade inspections are performed by separate inspectors and need not fall on one day, plumbing groundwork is inspected before the floor closes, and insulation after framing but before drywall.

A detached deck under 200 square feet and under 3 feet high is exempt outside the Critical Area and Bog Contribution Drainage Area; inside either, it is not.
How soon can I book the first inspection?
The permit must have been active for 24 hours before the first inspection can be requested.
