CA AB345

Requires local agencies to allow accessory dwelling units (ADUs) to be sold or conveyed separately from primary residences to qualified buyers if property was built by a qualified nonprofit corporation and held under a recorded tenancy in common agreement.

Adds mandatory provisions for tenancy in common agreements recorded after December 31, 2021, including delineation of exclusive use areas, allocation of costs and responsibilities among cotenants, and dispute resolution procedures before legal action.

Establishes that qualified buyers are persons and families of low or moderate income, and qualified nonprofits are 501(c)(3) organizations with welfare exemptions that operate special no-interest loan programs for low-income families.

Requires affordability restrictions ensuring ADUs remain low-income housing for 45 years and must be resold to qualified buyers, with a repurchase option giving nonprofits first right to purchase.

Provides state reimbursement to local agencies and school districts for costs mandated by the bill through existing statutory procedures if the Commission on State Mandates determines such costs exist.
