2025 Expected Housing Law Changes

HB 1337 (ADU Law Changes)

  • Allows up to two ADUs (Accessory Dwelling Units) per lot in single-family zones, including Detached ADUs (DADUs).

  • Simplifies and speeds up the permitting process for homeowners wanting to build ADUs.

  • Removes minimum lot size requirements and parking mandates for ADUs, making it easier for smaller lots to add units.

  • Provides incentives for homeowners who rent their ADUs at affordable rates.

  • Homeowners are no longer required to live on-site to rent out ADUs, allowing more flexibility in renting or managing properties.

  • Allows duplexes, triplexes, and fourplexes to be built in single-family residential zones, increasing density and housing options in previously restricted areas.

  • Cities are encouraged to provide further density bonuses or incentives if a certain percentage of units are affordable.

  • Property owners are permitted to split larger lots into smaller parcels, facilitating the development of additional housing units.

  • Promotes denser housing near public transit, with relaxed zoning restrictions for areas close to bus, light rail, and other transit corridors.

  • Encourages the development of vacant or underused lots in urban areas, promoting more efficient use of land and addressing housing shortages.
