Creates several new provisions for property development

HB 3297 allows residential development in commercial or industrial zones if at least 40% of units are affordable for 30 years, prohibiting local governments from requiring zoning changes or special approvals for such projects. It mandates minimum density and height standards based on existing local rules and permits administrative approval without additional board review. The bill also creates property tax exemptions for qualifying affordable housing: full exemption for households earning ≤80% of median income, and 75% exemption for 80-120% of median income, applicable to new multifamily projects with over 70 units meeting income criteria. These tax benefits require annual applications with income verification and tenant restrictions, effective for tax year 2027.
