Queen Anne's County — county ADU rules and overlays
County ADU ordinance
Queen Anne's County permits one Accessory Apartment per single-family lot as an accessory residential use under Article VI of the County Zoning Ordinance (Chapter 18:1). The unit must be inside the principal dwelling or an approved residential accessory structure, must be 1,500 sq ft or less, and the owner of the principal dwelling must reside on the property. On septic-served parcels the County Health Department must approve the unit. Accessory apartments do not count against the parcel's permitted dwelling-unit density.
- Queen Anne's County Code Chapter 18:1, Article VI - Accessory Uses (accessory apartment standards)
- Queen Anne's County Code Chapter 18:1 - Zoning and Subdivision Regulations
- Maryland HB 538 (2024) - Manufactured Homes - Accessory Dwelling Units (state ADU preemption framework)
State-floor overlay: Maryland's 2024 ADU preemption framework establishes a statewide floor; Queen Anne's County's accessory-apartment ordinance must conform to or exceed it. The county's existing 1,500 sq ft, owner-occupancy, and density-exclusion rules are not inconsistent with the state floor.
County regulatory overlays
Queen Anne's County is dominated by two overlay programs that materially affect ADU feasibility: the Maryland Chesapeake Bay Critical Area Program (every parcel within 1,000 feet of tidal water - which covers the bulk of Kent Island, Kent Narrows, the Chester River and Wye River frontages, and Eastern Bay shoreline) and the FEMA National Flood Insurance Program (the county has 414+ miles of coastline and 29.2 sq mi of water area, making large portions of the inhabited county flood-prone). Forest conservation and a historic-resources inventory also apply across the county.
- Chesapeake Bay Critical Area (Queen Anne's County Chapter 14:1) — An ADU proposed inside the Critical Area Buffer is the single most common reason a Queen Anne's County accessory-apartment project fails feasibility. RCA parcels carry density caps as restrictive as 1 dwelling unit per 20 acres in some configurations; an accessory apartment that is not counted against density (per Article VI) still requires Critical Area review and Buffer compliance.
- FEMA NFIP Special Flood Hazard Areas in Queen Anne's County — For a detached ADU on a shoreline parcel, the cost impact of BFE+2 elevation, foundation engineering, and flood insurance premium increase typically exceeds the cost of the structure itself. An in-dwelling accessory apartment inside a primary structure that is already elevation-compliant is far easier than a new detached unit on the same parcel.
- Forest Conservation (Queen Anne's County) — Forest Conservation Plans, when triggered, can require afforestation or fee-in-lieu payments. Most single-unit accessory-apartment projects are below threshold but should be confirmed at intake.
- Queen Anne's County Historic Resources — Confirm whether a parcel is in a designated historic district or carries an individual listing at the Planning & Zoning intake before designing.
County permitting (unincorporated parcels)
Queen Anne's County issues building, zoning, and accessory-apartment permits for parcels in unincorporated territory through the Department of Planning and Zoning's Permitting & Zoning office in Centreville. The department administers the County Zoning Ordinance, the Critical Area Ordinance (Chapter 14:1), subdivision regulations, and the forest conservation regulations. Inside the County's incorporated towns (Barclay, Centreville, Church Hill, Millington, Queen Anne, Queenstown, Sudlersville, Templeville) the towns issue their own zoning approvals, but the County still administers building-code review and floodplain review through county staff in most cases.
Maryland state — ADU law and programs
State ADU law
Maryland enacted statewide ADU preemption with the Accessory Dwelling Units Act of 2025 — HB 1466 / SB 891 (cross-filed) — passed by the General Assembly in the 2025 Regular Session and effective 2025-10-01. Counties and municipalities with planning and zoning authority must adopt local laws compliant with the Act by 2026-10-01. The Act establishes that it is the policy of Maryland to promote and encourage ADU creation on land with a primary single-family detached dwelling. ADUs are defined as secondary units on the same lot/parcel/tract as a primary single-family detached dwelling, no greater than 75% of the size of the primary dwelling. Counties and municipalities cannot prohibit ADUs or impose unreasonable restrictions on their construction or rental. The 2025 ADU Act ALSO amends the Maryland HOA Act (Title 11B of the Real Property Article), prohibiting community associations from prohibiting or unreasonably restricting ADU construction and rental. The state has been preparing this framework since 2023 (SB 382 created the ADU Policy Task Force, which issued its final report 2024-05-31).
State HOA preemption
Maryland enacted HOA preemption for ADUs as part of the 2025 ADU Act. HB 1466 / SB 891 amended the Maryland Homeowners Association Act (Real Property Article, Title 11B), adding the ADU definition at §11B-101(a-1) and prohibiting HOAs from prohibiting or unreasonably restricting the construction or rental of ADUs on lots with primary single-family detached dwelling units. HOAs retain authority to (a) treat an ADU as a separate lot for voting and assessment purposes (optional, not required) and (b) impose reasonable design and architectural standards consistent with the community's overall character. The HOA preemption became effective 2025-10-01.
State financing programs
Maryland does not currently operate an ADU-specific statewide loan, grant, or forgivable-loan program tied to the 2025 ADU Act. The Maryland Department of Housing and Community Development (DHCD) administers a broad portfolio of homeownership, rental development, and home-repair financing — including the Maryland Mortgage Program, Settlement Downpayment Loan Program, Project Restore (commercial-to-residential conversions), and various Energy & Home Repair loan products. None target ADU construction directly, though Project Restore can fund ADU-like conversions, and the Energy & Home Repair Loan can fund ADU-related electrical, HVAC, and weatherization upgrades.
State housing programs
Maryland's primary state-level ADU program is the 2025 ADU Act framework: statewide preemption requiring local jurisdictions to adopt compliant ordinances by 2026-10-01, including HOA preemption. The Maryland Department of Planning maintains an ADU resource hub with technical assistance for local governments. Maryland does not currently operate a statewide pre-approved ADU plan catalog, an ADU rebate, or an impact-fee waiver statute, but the local-compliance window through 2026-10-01 is expected to produce additional ADU-specific incentive programs.
- ADU Act 2025 Statewide Floor (HB 1466 / SB 891) — Counties and municipalities with planning/zoning authority must adopt compliant ordinances by 2026-10-01, allowing ADUs on every single-family-detached lot at up to 75% of primary dwelling size. Bars prohibitions and unreasonable restrictions. Includes HOA preemption.
- Maryland Department of Planning ADU Resource Hub — Resource hub with model ordinances, FAQs for local governments (HB 1466 FAQ), task-force final report, and statewide ADU ordinance inventory.
Federal (United States) — ADU-relevant rules and programs
Federal ADU law
The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.
Federal financing programs
Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.
Federal tax credits
There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.
Federal housing programs
HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
