To Amend The Law Concerning Municipal Regulations; And To Prohibit Certain Restrictions On The Regulation Of Accessory Dwelling Units.
HB1503 amends Arkansas municipal regulation law to limit local governments’ ability to restrict accessory dwelling units (ADUs) on lots with single-family homes. The bill defines key terms such as accessory dwelling unit, by right approval, short-term rental, and single-family dwelling, and it requires municipalities to allow at least one ADU by right on qualifying parcels, subject to applicable state and local regulatory requirements such as fire code, zoning, and design standards.
The bill sets specific limits on what cities and towns may require for ADUs. It bars municipalities from imposing additional parking requirements, owner-occupancy mandates, family or employment relationship rules between occupants, restrictive design matching rules, separate water and sewer connections, and certain development standards that are more restrictive than those applied to the primary dwelling. It also caps ADU application review fees at $250, allows usual building fees in addition, and states that conflicting local ordinances in effect on or after January 1, 2026, are invalid to the extent of the conflict. The bill preserves municipal authority over short-term rentals and allows more permissive local rules.
In practical terms, the bill preempts local ordinances that make ADUs harder to build or use, while still preserving baseline health, safety, and code compliance. It is likely to affect homeowners, developers, renters, and municipal planning departments by making ADUs more feasible statewide and reducing local discretion over zoning and permitting for these units.
The available voting history suggests the bill had broad legislative support, passing third reading in the House 67-19 and in the Senate 29-2. No committee transcript is provided, but the vote margins indicate generally favorable sentiment toward expanding ADU access and standardizing municipal treatment of these units.
The main point of contention is the balance between statewide housing policy and local control. Supporters likely view the bill as a housing-supply and affordability measure that removes unnecessary barriers, while opponents may be concerned that it limits municipal zoning authority, neighborhood character protections, parking management, and local infrastructure planning. The bill also draws a clear line by excluding short-term rental regulation from its protections, which may have been important to address concerns about vacation-rental use of ADUs.
HB1503 would add a new section to Arkansas Code Title 14, Chapter 56, Subchapter 2, creating statewide rules for accessory dwelling units and limiting conflicting municipal ordinances. It preempts local governments from imposing a range of ADU-specific restrictions, caps certain fees, and makes noncompliant local policies invalid beginning January 1, 2026, while preserving general regulatory requirements and allowing municipalities to adopt more permissive standards.
The bill appears to have been received positively overall, based on strong third-reading vote margins in both chambers. The lack of recorded committee testimony limits insight into detailed debate, but the final votes suggest substantial bipartisan or cross-party support for easing ADU restrictions and promoting housing flexibility.
The central controversy is the extent to which the state should override municipal zoning and permitting authority. Likely concerns include loss of local control over density, parking, setbacks, design compatibility, utility connections, and neighborhood impacts. Supporters likely emphasize housing affordability, infill development, and property-owner flexibility, while opponents may worry about infrastructure strain and reduced ability for cities to tailor land-use rules to local conditions.
