You’ve found the perfect spot for your new shed. It’s level, it’s accessible, it’s out of the way — and now you’re wondering whether it’s actually legal to put a shed there.
In Anne Arundel County, the answer depends on your zoning district, your lot type, the size of the shed, and whether your property has any special overlays like the Critical Area or a Historic District. There is no single universal setback number that applies to every property in the county — which is exactly why so many homeowners get tripped up on this.
This guide explains how setbacks work in Anne Arundel County, what the general rules are for accessory structures like sheds, what factors vary by zone, what happens if you violate a setback, and how to get the exact answer for your specific property before your shed is delivered.
What Is a Setback, and Why Does It Apply to Sheds?
A setback is the minimum required distance between any structure on your property and a lot line, road right-of-way, or other boundary. Setbacks define the minimum required distance between a lot line and any structure on a property. Anne Arundel County
In Anne Arundel County, setbacks apply to two categories of structures: principal structures (your home or primary building) and accessory structures. Sheds, detached garages, carports, pools, and gazebos all fall into the accessory structure category.
The important thing to understand upfront: accessory structure setbacks in Anne Arundel County are governed by the county’s Zoning Ordinance — not just the building permit process. This means you can have a shed that technically doesn’t require a building permit (under 150 square feet) but still has to comply with setback rules. The two systems run in parallel.
Setbacks are determined at the zoning level in Anne Arundel County — not the building permit level. An accessory structure may not be located in a setback from a right-of-way line. MD Sheds
How Anne Arundel County Setbacks Are Determined
To determine the specific setback requirements in Anne Arundel County, you need to consider the property’s zoning classification, the type of development (such as a regular subdivision, cluster subdivision, or Planned Unit Development), and the type of structure — whether it’s a principal structure like a dwelling, or an accessory structure such as a shed, detached garage, or pool. Anne Arundel County
This is the most important thing to understand about Anne Arundel County setbacks: the numbers are district-specific. The county has eight residential zoning districts — RA (Rural Agricultural), RLD (Rural Low Density), R1, R2, R5, R10, R15, and R22 — plus commercial, industrial, maritime, and mixed-use districts, each with its own bulk regulations covering setbacks, lot coverage, height limits, and density.
What this means practically:
- A shed on an R1 property (low-density suburban, minimum 30,000 sq. ft. lots) has different setback requirements than a shed on an R2 property (medium-density suburban)
- A shed on a waterfront lot is governed by different front/rear yard definitions than an inland lot
- A property in the Critical Area Overlay — within 1,000 feet of the Chesapeake Bay or a tributary stream — has additional restrictions layered on top of standard zoning requirements
- A property in a Historic District may have further architectural review requirements
For specific information on your property’s setbacks, contact the Zoning Administration Section at 410-222-7437 or send a request through the county’s Contact Us portal. You will need to provide either the property address or the tax identification number. Anne Arundel County
That call is the only way to get a definitive answer for your specific parcel.
General Rules for Accessory Structures in Anne Arundel County
While the exact setback numbers vary by zoning district, the Anne Arundel County Code (Article 18) establishes several rules that apply broadly to accessory structures across residential zones. Here is what the code states:
No accessory structures in the front yard. An accessory structure may not be located in a setback from a right-of-way line, and accessory structures are generally not permitted in the front yard of a standard residential lot. There are narrow exceptions — through lots, corner through lots, and waterfront lots have different front yard definitions — but for most Anne Arundel County homeowners, the shed goes in the side or rear yard. AmLegal
Waterfront properties are different. On waterfront lots, the front yard faces the shoreline, not the road. This means an accessory structure on a waterfront lot may be placed in what would be the “front” yard (facing the street) without violating the front yard prohibition — because legally, the waterfront side is the front. An accessory structure on a waterfront lot may be located in the front yard, with the Office of Planning and Zoning designating the permitted location. Amazon S3
Setbacks increase with structure height. Setbacks for storage sheds and other accessory structures are based on a minimum setback, plus additional distance depending on the height of the structure. A taller shed needs more clearance from the property line than a shorter one. This is why specifying your shed’s height when you call the zoning office is important — not just the footprint. Annapolis
A structure too close to your house becomes part of it. A structure located within three feet of a principal structure, and a structure connected to a principal structure by an enclosed breezeway less than 15 feet long, is part of the principal structure and is not an accessory structure. If you place your shed within three feet of your home, it no longer qualifies as a separate accessory structure for setback purposes — it’s treated as an addition to the house, with all the stricter setback and permit requirements that entails. AmLegal
You cannot build in an easement. Any easements on your property — utility easements, drainage easements, access easements — restrict where structures can be placed. Easements should be shown on your property plat. If you don’t have a copy of your plat, you can obtain one through the Anne Arundel County land records office.
Septic system setbacks apply separately. Property improvements such as sheds and garages require a County building permit and these types of building permit applications are approvable provided that the minimum setback requirements from well and septic systems can be met. If your property is on a private well or septic system, additional minimum distances from those systems apply. The Anne Arundel County Health Department handles these requirements separately from the zoning setbacks. Anne Arundel County Department of Health
The Permit Threshold and How It Interacts with Setbacks
It’s worth being clear on how permits and setbacks relate, because many homeowners assume one determines the other. They don’t.
In Anne Arundel County, one-story detached accessory structures used as tool and storage sheds are exempt from building permits provided the average height doesn’t exceed 10 feet and the floor area doesn’t exceed 150 square feet. So a typical 10×12 (120 sq. ft.) shed does not require a building permit in Anne Arundel County. MD Sheds
But no permit does not mean no rules. Setback requirements apply to every shed, regardless of size. A 100-square-foot shed that doesn’t need a permit still needs to be placed in compliance with your zoning district’s accessory structure setbacks. Setback distances vary by county and by zoning district within each county. In Anne Arundel County, setbacks are determined at the zoning level — not the building permit level. MD Sheds
This is the detail that catches people off guard most often. They confirm they don’t need a permit, they order the shed, and on delivery day they find out the placement they had in mind violates a setback. The shed either has to go somewhere else, or they’re looking at a violation.
The correct order of operations:
- Identify your zoning district (use the MyAnneArundel County Map Viewer online, or call 410-222-7437)
- Confirm your accessory structure setback requirements with the Zoning Administration Section
- Confirm whether your desired placement conflicts with any easements (check your plat)
- If your property is on well/septic, confirm Health Department setbacks (410-222-7219)
- Determine whether the shed size triggers a building permit (over 150 sq. ft. = permit required)
- Order your shed and have it delivered to the confirmed location
What Happens If You Violate a Setback in Anne Arundel County
This is not a paperwork technicality. Setback violations have real consequences.
If you violate a setback, you may be required to move or remove your shed even if it was otherwise built legally. This is one of the most common and costly mistakes Maryland homeowners make — and it’s entirely avoidable with a quick call to your county zoning office before delivery day. MD Sheds
In Anne Arundel County specifically, fines for setback violations start at $125 and increase with repeated violations. But the fine itself is often the least of it. The more significant cost is moving or relocating the structure — or, in the worst case, being ordered to remove it entirely. Pro Landscape
Setback violations can also surface during:
- Home sales. A buyer’s inspector or attorney may flag an unpermitted or improperly placed structure. This can delay or derail a sale, require permits after the fact, or force relocation of the shed before closing.
- Insurance claims. If a non-compliant structure is damaged, your insurer may deny or reduce the claim.
- Neighbor complaints. A neighbor who observes a structure too close to the property line can file a zoning complaint, which triggers an inspection.
There is no automatic grandfathering in Anne Arundel County. If the use of a property does not fall within those allowed by the current Zoning Ordinance, the property owner must apply to register as either a Nonconforming Use or a Twenty-Year Registered Use with the Office of Planning and Zoning. If you have a shed that was placed years ago without checking setbacks, it’s worth verifying its compliance before you sell the property. Anne Arundel County
Special Situations That Change the Rules
Critical Area properties. The Critical Area Overlay applies to land within 1,000 feet of the Chesapeake Bay, tidal wetlands, and tributary streams. Anne Arundel County has significant Critical Area coverage, particularly in communities along the South River, Severn River, Magothy River, Patuxent River, and the Bay itself. Critical Area regulations restrict impervious surface, require buffers from the shoreline, and impose stricter review on all development including accessory structures. If your property is in the Critical Area, contact the Office of Planning and Zoning before ordering any structure.
Historic District properties. Anne Arundel County has designated Historic Districts where exterior modifications — including adding accessory structures — may require additional review. If your property is in or adjacent to a designated historic area, confirm whether historic review applies.
HOA communities. Many Anne Arundel County neighborhoods are governed by HOAs with CC&Rs that impose restrictions beyond what the county code requires. An HOA may restrict shed size, materials, color, placement, or require architectural review board approval. HOA approval is a separate process from county permitting — you need both. Always obtain written HOA approval before ordering.
Corner lots. Corner lots have two street frontages, which affects which yard is the front yard and can complicate setback calculations. If your lot is on a corner, clarify the front lot line determination with the Zoning Administration Section before placing any structure.
Properties on well and septic. For property improvements on private well and septic systems, the site plan must show the existing septic system size and location, well location and tag number, property lines, proposed construction, neighboring wells, and septic systems within 100 feet. Sheds must maintain minimum separation distances from wells and septic components. The Health Department reviews these requirements as part of the permit process.

How to Look Up Your Zoning and Setback Requirements
Step 1: Find your zoning district. Use the MyAnneArundel County Map Viewer — enter your address and look for the zoning classification. Common residential classifications include RA (Rural Agricultural), R1, R2, and R5.
Step 2: Call the Zoning Administration Section. For specific setback requirements, contact the Zoning Administration Section at 410-222-7437. You will need to provide either the property address or the tax identification number. Tell them your zoning district and that you’re planning a detached accessory structure (shed), and give them the height and footprint. They will confirm the required setbacks for your situation. Anne Arundel County
Step 3: Check your plat for easements. Your property plat shows the recorded easements that affect your lot. Obtain a copy through the Maryland State Archives land records system or your county’s land records office.
Step 4: If on well/septic, call the Health Department. The Anne Arundel County Department of Health can be reached at 410-222-7219 to confirm separation distances from your well and septic system.
Step 5: Check your HOA documents. If you’re in an HOA, pull your CC&Rs and review the section on accessory structures and architectural modifications. If it’s unclear, submit a written request to the HOA board for approval before you order.
Frequently Asked Questions
What is the minimum setback for a shed in Anne Arundel County?
There is no single county-wide number. Setback requirements vary based on the property’s zoning classification, the type of development, and whether the structure is a principal or accessory structure. The minimum side and rear setback for an accessory structure in a standard residential district typically starts in the range of 5 to 10 feet from the property line, but the precise requirement for your lot depends on your zoning district. Call the Zoning Administration Section at 410-222-7437 with your address to get the specific number. Anne Arundel County
Does a shed under 150 square feet still have to follow setback rules in Anne Arundel County?
Yes, absolutely. The 150 square foot threshold determines whether a building permit is required — it has no effect on zoning setbacks. Setbacks are determined at the zoning level, not the building permit level. Setback rules apply regardless of whether a permit is required. Even a small shed needs to be placed in compliance with your zoning district’s accessory structure setbacks. MD Sheds
Can I put a shed in my front yard in Anne Arundel County?
Generally no. Accessory structures may not be located in the front yard of a standard residential lot, with limited exceptions for through lots, corner through lots, and waterfront properties. For most homeowners, sheds must go in the side or rear yard. Amazon S3
What happens if my shed violates a setback?
If you violate a setback, you may be required to move or remove your shed even if it was otherwise built legally. Fines start at $125 in Anne Arundel County and increase with repeated violations. Violations can also complicate home sales and insurance claims. The safest approach is to confirm setbacks before your shed is delivered. MD Sheds
How close to my house can I place a shed in Anne Arundel County?
A structure located within three feet of a principal structure is considered part of the principal structure, not an accessory structure. In practice, keeping your shed at least 5 to 6 feet from your home gives you clearance from both the “becomes part of the house” rule and typical setback requirements. Your exact allowable distance from the home may also be governed by fire separation requirements — confirm with the building permit office if you’re planning a close placement. AmLegal
My property is on the Chesapeake Bay. Are the rules different?
Yes, significantly. Properties in the Critical Area Overlay — within 1,000 feet of the Bay, tidal wetlands, or tributary streams — have additional restrictions on impervious surface, buffer areas, and development review. Contact the Anne Arundel County Office of Planning and Zoning before planning any accessory structure on a waterfront or near-waterfront property.
Do HOA rules apply on top of county setback rules in Anne Arundel County?
Yes. HOA restrictions are enforced separately from county zoning rules. Your HOA CC&Rs may require larger setbacks than the county minimum, restrict shed materials or colors, require architectural review approval, or prohibit certain structure types entirely. You need to comply with both. Always get written HOA approval before ordering.
Where do I go to get the official setback for my property?
Contact the Zoning Administration Section at 410-222-7437 or submit a request through the county’s online Contact Us portal. You will need to provide your property address or tax identification number. This is the authoritative source — not a neighbor, not an online forum, and not a general guide like this one.
