AB 939 California Assembly · 2025-2026 Regular Session

Housing development: density bonuses: affordability of for-sale units.

Summary
Existing law, commonly referred to as the Density Bonus Law, requires a city or county to provide a developer that proposes a housing development, as defined, within the city or county with a density bonus, other incentives or concessions, and waivers or reductions of development standards, as specified, if the developer agrees to construct specified units and meets other requirements. Existing law, among other things, requires compliance with certain affordability requirements, including requiring that the applicant agree to ensure, and that the city, county, or city and county ensure, that a for-sale unit that qualified the applicant for the award of the density bonus is either (1) initially sold to and occupied by a person or family of very low, low, or moderate income, as specified, or (2) if the unit is not purchased by an income-qualified person or family within 180 days after the issuance of the certificate of occupancy, the unit is purchased by a qualified nonprofit housing corporation, as provided. This bill would additionally allow the applicant and the city, county, or city and county to comply with the above-described affordability requirements with respect to a for-sale unit by ensuring that the unit is purchased by a nonprofit housing corporation, as specified, for properties to be sold to and occupied by extremely low, very low, or lower income families who participate in a below market interest rate loan program, as described. By adding to the duties of local agencies to implement the Density Bonus Law, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

MINOR
The diff reflects a change in document presentation format rather than a substantive policy change. The formal legislative document (with amendment history, line numbers, page headers, and Legislative Counsel's Digest) was replaced by what appears to be a web page rendering of the same bill text, complete with navigation menus, search fields, and site links. No changes to the actual statutory language or policy content are evident in the visible portion of the diff.
TECHNICAL

Removed formal legislative document formatting including amendment history dates, line numbers, page headers (e.g., 'AB 939 -2-'), and the Legislative Counsel's Digest section.

Added website navigation and UI elements including links for home, accessibility, FAQ, feedback, sitemap, login, quick search fields, bill number/keyword search, and site sections like California Law, Publications, and Other Resources.
