CA AB1490

Establishes "extremely affordable adaptive reuse projects" as an allowable use in local jurisdictions if meeting objective planning standards, including 100% of units dedicated to lower income households with at least 50% for very low income households.

Requires adaptive reuse projects to be located on infill parcels not on or adjoined to sites where more than one-third of square footage is dedicated to industrial use, though local agencies may deny projects with any industrial use if they find adverse public health and safety effects.

Limits local agency authority to impose objective design review standards only; prohibits requiring curing of preexisting density, floor area ratio, parking, or open space deficits for qualifying projects.

Mandates local agencies determine within 60-90 days (depending on unit count) whether a submitted project meets applicable standards, with deemed approval if no timely determination is made.

Requires local sources of funding for affordable housing to include adaptive reuse as an eligible project and prohibits agencies from excluding adaptive reuse proposals solely based on the reuse model.
