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 twenty-five certified inspectors, and the overlay that shapes its work is the Chesapeake Bay Critical Area: the land within a thousand 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 twenty-four 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 three feet high, and gazebos up to 150 square feet and ten 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.
What requires a building permit in Anne Arundel County?
Maryland runs on one statewide instrument, the Maryland Building Performance Standards (COMAR 09.12.51), and enforces it locally. The state adopts each new edition of the International Building Code, the International Residential Code and the International Energy Conservation Code, with Maryland modifications, and every jurisdiction must adopt and enforce the same edition within twelve months — counties and the cities that keep their own permit offices may amend the building and residential codes to suit local conditions, but may make the energy code and the Maryland Accessibility Code only more stringent, never less. The 2021 editions, effective statewide on May 29, 2023 with local enforcement required by May 29, 2024, replaced the 2018 editions; the Maryland Building Rehabilitation Code carries the existing building code beside them. What is local in Anne Arundel County is the enforcing office, its amendments, its fee schedule, and the grading, stormwater, forest conservation and Critical Area approvals that run ahead of the building permit.
The codes draw the exemption line and the local amendments move it. The IRC's work-exempt-from-permit list — small accessory structures, low fences, minor repairs — applies as Anne Arundel County adopted it, and the jurisdiction's own ordinance may narrow it. Electrical, plumbing and gas work carry their own permits under the state licensing boards' rules, and zoning, grading and sediment control approvals are separate from all of them.
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 three feet high, and gazebos up to 150 square feet and ten 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 and stormwater ordinances under the state's delegation, and the Chesapeake Bay Critical Area and the Bog Contribution Drainage Area, which decide what is exempt long before the building code does.
Who handles permitting in Anne Arundel County?
The Department of Inspections and Permits is the enforcing office, with more than twenty-five certified inspectors covering the county, and the Codes Enforcement Administration within it. Zoning is administered from the same Riva Road complex, the Office of Planning and Zoning handles Critical Area and land development review, and the fire marshal's office inspects commercial and tenant improvement work before the final building inspection can be scheduled.

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. Structural and building permits are pulled by a contractor holding the state home improvement licence; electrical, mechanical and plumbing permits are pulled by the master licence holders for each trade, and the county verifies those state licences at intake. Plumbing groundwork is inspected before the floor closes, and insulation after framing but before drywall.
How Maryland contractor credentials work
Maryland has no state general contractor license for commercial work, but home improvement is licensed outright: the Maryland Home Improvement Commission licenses contractors who alter, repair or improve residential property, with an examination, proof of financial solvency and a guaranty fund that pays homeowners for a licensee's defective or incomplete work. New construction is different again: a home builder registers with the Home Builder Registration Unit of the Attorney General's Consumer Protection Division under the Maryland Home Builder Registration Act, and the registration number goes on the permit. Electricians, plumbers and gas fitters, and HVACR contractors are licensed statewide by their boards at the Department of Labor, and Anne Arundel County verifies those licenses at the permit counter. Owner-occupants may build on their own home without the home improvement license, and Anne Arundel County licenses no trades of its own beyond any local registration its ordinance keeps.
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
A Maryland building permit is one application reviewed by the local office's plan reviewers for the building, residential and energy codes, with the electrical, plumbing and mechanical trades permitted alongside it. The approvals that run ahead of it are the ones that decide the schedule: zoning certification, a grading permit with a sediment and erosion control plan approved by the soil conservation district, stormwater management under the Maryland Department of the Environment's delegation, forest conservation under the Forest Conservation Act where the site disturbs enough land, and Critical Area review within a thousand feet of tidal waters. In Anne Arundel County the Chesapeake Bay Critical Area reaches a thousand 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. Unlike the states with a statutory review clock, Maryland leaves review times to each jurisdiction — Anne Arundel County publishes its own targets, and they are the number to plan against.
Anne Arundel County permit costs and fees
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 | Valuation-based on the county schedule; the portal calculates the figure for a given application |
| Reinspection | Charged where a scheduled inspection is not cancelled at least twenty-four 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 licensed tradesmen |
| First inspection | Not available until the permit has been active for twenty-four 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 reinspection fee where a scheduled inspection is not cancelled at least twenty-four 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 twenty-four-hour cancellation rule is the one to diary.
Trade permits and who may pull them
Trade work is permitted separately from the building permit in most Maryland jurisdictions and inspected by the office's trade inspectors, with the state boards' licenses verified at issuance.
Permit required
- Structural and building permits — state home improvement licence; each trade permit by its own master licence holder
- Electrical — state-licensed master electrician; separate electrical permit
- Plumbing and gas — state-licensed master plumber or gas fitter; separate plumbing and gas permits
- HVACR — state-licensed HVACR contractor; mechanical permit
- Fire protection, alarms and sprinklers — fire marshal review, state or local, with the building permit
Typically exempt
- Like-for-like fixture, receptacle and switch replacement where the licensing boards' rules allow it
- Low-voltage and communications wiring below the local permit threshold
How to apply for a 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 Maryland Home Improvement Commission license, or the home builder registration 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 in Anne Arundel County
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 twenty-four 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.
