Department of Housing and Community Development - Appraisal Gap From Historic Redlining Financial Assistance Program - Qualified Properties
Summary
HB1466 establishes a statewide framework for accessory dwelling units (ADUs) on lots zoned for single-family detached residential use. It requires certain counties and municipal corporations to adopt local laws authorizing ADUs by October 1, 2026, and sets baseline rules for how those local laws must operate. The bill defines ADUs, limits their size relative to the primary dwelling, and requires local approval standards to be objective and measurable rather than based on subjective judgments such as neighborhood compatibility or aesthetics.
The bill also limits local barriers to ADU development. It requires ministerial review of complete zoning permit applications within 90 days, restricts local governments from imposing certain parking requirements, caps or prohibits development impact fees and building excise taxes for smaller units, and limits utility connection requirements and fees when existing water or sewer service is sufficient. In addition, it prevents private restrictions on real property from unreasonably blocking ADUs and authorizes homeowners associations to treat an ADU as a separate lot for voting and assessment purposes.
Impact
The bill amends the Land Use Article to add a new subtitle on accessory dwelling units and makes that subtitle applicable to charter counties and Baltimore City. It also adds related provisions to the Real Property Article to invalidate certain deed, covenant, and HOA restrictions that would unreasonably limit ADU development, while preserving an exception for historic property. The measure further amends HOA law to allow ADUs to be treated as separate lots for voting and assessment purposes, and it creates statewide constraints on local zoning, permitting, parking, fee, and utility rules affecting ADUs.
Sentiment
The voting history shows strong bipartisan support, with the House passing the bill 137-1 and the Senate passing it 47-0. No committee transcript excerpts were provided, but the overwhelming margins suggest broad agreement with the bill’s housing-supply goals and its effort to standardize ADU rules across jurisdictions. The overall sentiment appears favorable and pragmatic, centered on expanding housing options while preserving local implementation details within the bill’s limits.
Contention
The main points of contention reflected in the text are between state-level ADU promotion and local control over zoning and neighborhood standards. The bill limits local discretion by prohibiting subjective approval criteria, restricting parking mandates, and preventing local rules from effectively banning ADUs through fees or setbacks. Another potential area of concern is the bill’s override of private land-use restrictions and HOA rules, though it preserves some exceptions, including for historic properties and certain local safety or infrastructure conditions. These provisions suggest the bill balances housing expansion against local infrastructure, neighborhood, and property-rights concerns.
