Anne Arundel County, MD Building Permits & Zoning

Anne Arundel County, Maryland requires a building permit for a new single-family home, and the county's own Department of Inspections and Permits issues it, not the state¹. The county zones land under Article 18 of its code, with bulk rules on lot size, setbacks, coverage and height that vary by district². The Department of Health's Sanitary Engineering Program reviews, permits and inspects private septic systems and wells³. If you will build the home yourself for your own use, a Homeowner Affidavit can let you skip a builder's registration number⁴.

Do you need a building permit in Anne Arundel County, Maryland?

Yes, for a new single-family dwelling: the county's own page lists it as a newly constructed or rebuilt stand-alone residential structure, and marks it "Permit Required"⁹. Permit necessity in general depends on the scope and nature of the work, and a project can also need trade permits, a grading permit, or approvals from the Office of Planning and Zoning or the Department of Public Works' Rights of Way Division¹. Once a permit is issued, it's the permit holder's job to contact the county when construction reaches a stage that requires an inspection, such as framing or rough-in¹⁰. A qualifying agricultural building can be exempt from the building permit if it is on a farm with a current soil-conservation and water-quality plan, is zoned RA (or RLD and assessed as agricultural by the state), stays under 40 feet tall, sits at least 60 feet from other buildings, and is not open to the public¹¹.

Who issues building permits in Anne Arundel County, and how do you reach them?

The Anne Arundel County Department of Inspections and Permits runs the county's Permit Center at 2664 Riva Road in the Heritage Office Complex in Annapolis, and can be reached at (410) 222-7730 or [email protected]¹². Most new permit applications now go through the county's online Land Use Navigator (LUN) system rather than paper¹². A non-refundable $43 application fee is added to every building permit, the minimum building permit fee is $86, and fees climb from there based on the estimated value of the work; a missed or inaccessible inspection costs a $150 reinspection fee¹³. A citizen building a new home for personal use and submitting a Landowner Affidavit is exempt from the separate $50 home-builder fee that applies to registered builders¹³.

Does Anne Arundel County have zoning?

Yes. Anne Arundel County zones land under Article 18 of the county code, with eight residential, four commercial, three industrial, five maritime and four mixed-use zoning districts, plus overlays¹⁴. Bulk rules vary district by district: in the county's R1 district, the minimum lot size is 30,000 square feet (15,000 square feet for a side-by-side duplex), structures may cover up to 50% of the lot, principal buildings top out at 45 feet, and setbacks run 35 feet in front, 30 feet in back, 15 feet on the side, and 50 feet from a principal arterial road⁸¹⁵¹⁶¹⁷. Land within 1,000 feet of the Chesapeake Bay or its tributary streams falls under the county's Critical Area Overlay, which adds development rules on top of the base district¹⁴. The Office of Planning and Zoning's Zoning Enforcement Section investigates suspected violations, and enforcement is complaint-driven¹⁸.

How do septic and well permits work in Anne Arundel County?

The Department of Health's Sanitary Engineering Program reviews and approves properties for private septic systems and wells, issues the construction permits, and inspects both once installed³. A Septic Installation Permit is required for any onsite sewage disposal system, commercial or residential, and it starts with a perc-test application; a subdivision served by private well or septic needs a separate subdivision application to the Health Department¹⁹. Statewide, that construction permit is valid for no more than two years and can't be issued if the system might pollute a water supply or if a safe water supply isn't available²⁰. Wells must be drilled by a licensed Master Well Driller, who submits the permit application; after drilling, the county inspects the well and runs potability testing, and you need a Certificate of Potability before the water can be used²¹. Reach the Sanitary Engineering Program's septic line at 410-222-7193 ([email protected]) and the wells line at the same number ([email protected])²². If a new residential subdivision is Growth Tier 1, it must connect to public sewer; Tier 2 minor subdivisions may use septic short-term but must connect once public sewer is available; Tiers 3 and 4 rely on septic or private community systems²³.

Can you live in an RV, tiny home, or camp on your land in Anne Arundel County?

We could not confirm an Anne Arundel County rule that specifically allows or prohibits long-term RV occupancy, temporary camping, or tiny-home occupancy on private land; ask the Office of Planning and Zoning before relying on any of those uses. A manufactured home has a clearer path: since January 1, 2025, it is allowed in any zoning district that permits single-family dwellings if it sits on a permanent foundation, the same person owns the land and home, and an affidavit of affixation is recorded in the land records⁵. Anne Arundel County also allows one accessory dwelling unit per lot in most residential districts, with no minimum lot size; a detached unit may be no larger than 800 square feet or half the floor area of the principal house, whichever is less⁶.

Building a home in Anne Arundel County: the steps, in order

Confirm the parcel's zoning district and bulk requirements (lot size, setbacks, coverage, height) with the Office of Planning and Zoning before you buy⁷.
If the site relies on a well or septic system, get a perc test and Health Department review, since a Septic Installation Permit and any well permit must be in hand before the county issues the building permit²².
Apply for the building permit through the county's Land Use Navigator system; if you will act as your own contractor for your own use, submit the Homeowner Affidavit instead of a builder's registration number⁴.
If the driveway will connect to a county road, apply for a Residential Driveway Access Permit from the Bureau of Highways²⁴; only one entrance is normally allowed, and a second entrance needs at least 100 feet of frontage plus county approval²⁵.
Schedule inspections at each required construction stage; it's the permit holder's responsibility to call the county when the work is ready¹⁰.
If any part of the project sits within a FEMA-mapped 100-year floodplain, get the required local floodplain development permit before you build²⁶.

What to check before you buy land in Anne Arundel County

Septic suitability is the biggest wildcard: only about 2% of the county's soil has no severe limitation for a conventional septic drain field, so get a perc test before you count on a standard system²⁷. A typical home here runs around $514,257 and farmland has recently been valued near $12,289 an acre²⁸²⁹; the effective property tax rate is about 0.9%, with a median annual bill around $3,836³⁰³¹, and typical home insurance runs about $1,654 a year³². If the parcel's driveway would connect to a State right-of-way rather than a county road, that's a separate MDOT State Highway Administration permit, coordinated through the applicable MDOT SHA district office³³. About 6.3% of the county is federal land, a reminder to double-check a rural-looking parcel isn't adjacent to or part of a federal installation before you assume full private use³⁴.

Watch-outs

We could not confirm an Anne Arundel County rule for long-term RV occupancy, temporary camping, tiny-home occupancy, or a minimum dwelling floor area; ask the Office of Planning and Zoning about your exact plan before relying on one⁷.
A driveway onto a county road needs the county's Residential Driveway Access Permit, and normally only one entrance is allowed per lot; a driveway onto a State-maintained road is a separate MDOT SHA permit instead²⁴³³.
The owner-builder Homeowner Affidavit only works if you are doing the work yourself for your own use and have not hired anyone to manage or supervise construction; hiring a manager later requires notifying the Department so a builder's registration can be added to the permit⁴.
