This ordinance significantly amends the San Francisco Planning Code to adjust regulations for commercial and residential-commercial districts. Key changes include principally permitting certain non-retail sales and service uses (like general office, business services, and trade offices) on the ground floor in C-3 (Downtown Commercial) Districts until December 31, 2030, after which they become conditionally permitted. It also principally permits retail and non-retail sales and service uses on the second floor and above in RC (Residential-Commercial) Districts. The ordinance updates transparency and fenestration requirements for ground floor active uses and exempts specific uses such as childcare facilities, homeless shelters, mortuaries, religious institutions, reproductive health clinics, and schools from these requirements. Furthermore, it modifies sign definitions and permitting exemptions, allowing interior signs within four feet of a window/door and exempting small interior signs (six square feet or less) and painted business/identifying signs on facades from permits. It also expands eligibility for residential conversion development impact fee waivers for existing Production, Distribution, and Repair (PDR) uses or other Non-Residential uses converted to residential. The legislative digest and ordinance highlight these changes are intended to streamline permitting, create jobs, businesses, and homes, and support the city's economic recovery.
