Relating to municipal permitting requirements for certain development projects supported with low income housing tax credit allocations.

HB 4398 requires municipalities with over 100,000 residents to process building permits for affordable housing projects using federal low-income housing tax credits within half the usual time allowed for residential permits. It directly affects large cities and developers of projects receiving these tax credits, streamlining approval for housing aimed at lower-income residents. The bill mandates that permit decisions must be made in 50% of the standard processing time, and allows applicants to use any existing accelerated review process. This policy change, effective September 1, 2025, aims to reduce delays for qualifying housing developments.
