ADU Incentives Pilot Program

加建合法附屬住宅單位 ADU 獎勵試點計劃

San Francisco District 4 Supervisor Gordon Mar, the San Francisco Planning Department, and ASIAN, Inc. have partnered to carry out an ADU Incentives Pilot Program in the Sunset District. Accessory Dwelling Units (ADUs), also called secondary units, in‑law units, or cottages, are units added to existing residential buildings. The goal of this program is to assess the potential for ADUs to serve as a stable, affordable source of housing in San Francisco. District 4 property owners interested in adding an ADU are encouraged to apply for technical assistance through this pilot program. Qualified applicants will receive a professional assessment of the potential to add an ADU on their property, at no cost.

舊金山第四區市參事馬兆明、舊金山規劃局和美亞輔鄰社合作在日落區開展加建合法附屬住宅單位 ADU 獎勵試點計劃。加建合法附屬住宅單位(ADUs)是在現有建築物上新增一個居住單位,也可被稱為第二住屋單位、姻親單位或小屋。該計劃旨在通過評估加建合法附屬住宅單位(ADUs)的潛力,為舊金山提供穩定的、可負擔的住房資源。我們鼓勵有興趣加建合法附屬住宅單位 ADU 的第四區房主通過此試點計劃獲得技術幫助。符合資格的申請者可以免費獲得專業的評估來得知該房屋加建附屬住宅單位 ADU 的潛力。

Am I Eligible to Take Part in this Pilot Project?


If you are a homeowner in District 4, and are interested in constructing an ADU on your property, please apply. Not sure if your property is located in District 4? Take a look at this map or enter your address in the Property Information Map and check which Supervisor District your property is in. Due to limited funding, not all applicants will be selected for the pilot program. However, data collected from this pilot program will be used to design a citywide, comprehensive ADU incentives program in the near future.
