CA AB748

Requires local agencies to develop a program for preapproval of single-family and multifamily residential housing plans, with large jurisdictions (cities with 25,000+ population) required to comply by July 1, 2027, and small jurisdictions by January 1, 2029

Mandates that local agencies approve or deny applications for housing units using preapproved plans ministerially within 30 days, without discretionary review, if the lot meets applicable conditions and the plan was preapproved within the current California Building Standards Code cycle

Requires local agencies to post preapproved housing plans and applicant contact information on their websites, and to remove plans within 30 days upon applicant request

Exempts projects using preapproved plans from California Environmental Quality Act (CEQA) review by making the approval process ministerial rather than discretionary

Excludes master-planned communities, planned unit developments, and large-scale subdivision developments from the preapproval program, and defines multifamily housing as buildings with 2-10 units
