Planning and zoning: housing development: streamlined approval and subdivisions

The law removes a sequencing barrier for eligible urban lot splits and small subdivisions, allowing housing and map applications to be reviewed together while retaining local building-standard review.

What the law does ​

• Requires concurrent processing of qualifying two-unit housing applications and urban lot-split parcel-map applications.
• Requires concurrent processing of qualifying housing-project or building-permit applications with parcel-map or tentative-and-final-map applications for eligible subdivisions of up to 10 parcels and 10 homes.
• Lets local governments withhold building, grading, or occupancy permits until the required subdivision map is approved and recorded.
• Allows local governments to require permit revisions when map review identifies noncompliance with applicable development or building standards.
• Clarifies that an urban lot-split parcel map may include a condominium plan, subject to applicable approval requirements.

Who it affects ​

• Homeowners and developers seeking qualifying two-unit projects with urban lot splits.
• Developers of qualifying small housing subdivisions and projects of up to 10 homes.
• Cities and counties processing subdivision maps, housing applications, and construction permits.
