One Front Door Act of 2025

The definition of a 'multifamily residential building' was changed from paragraph (9A) to paragraph (10A) in the code.

A new requirement was added to limit buildings with single stairways to either no more than 4 units per floor or a commensurate limit on square footage per floor.

A new provision was added to prohibit dwelling unit doors from opening in the direction of an interior exit stairway, changing the previous rule that simply prohibited them from opening directly into the stairway.

The list of factors the Department of Buildings must consider when drafting rules was expanded to include the new unit/square footage limits and the updated door opening prohibition.

A new subsection was added to clarify that the list of considerations for the Department of Buildings does not limit their future authority to amend rules.

The text regarding the timeline for rulemaking was slightly rephrased for clarity, changing 'up to six stories above grade plane, or a high-rise building' to 'up to 6 stories above grade plane or high-rise buildings'.

The effective date section was updated to include the specific approval date of the District of Columbia Home Rule Act (December 24, 1973) and to explicitly mention publication in the District of Columbia Register.

Signatures for the Chairman, Council, and Mayor were added to the final enrolled version of the bill.
