Frequently Asked Questions

An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family or multi-family residential lot. Building one in San Francisco lets you add rental income, house family members, or create a home office without buying new land. The city's housing crunch makes ADUs a smart investment for property owners. They're a practical way to maximize your property's potential and increase its overall value. Plus, San Francisco has streamlined the permitting process for ADUs, making it more accessible than ever.
Building an ADU in San Francisco typically takes 12 to 18 months from initial design to final inspection, including permitting time. The design and permitting phase often takes the longest, usually 6-9 months, due to city reviews and specific San Francisco planning codes. Construction itself usually runs for 4-6 months, depending on the complexity of the unit and site conditions. We work efficiently, but we also make sure everything meets San Francisco's strict building standards.
The typical cost for an ADU project in San Francisco ranges from $200,000 to $400,000, depending on size, finishes, and site preparation. This estimate covers everything from architectural plans and permits to construction and utility hookups. Factors like hillside excavation, foundation work in areas with challenging soil, or high-end interior finishes can increase the total investment. We provide a detailed breakdown so you know exactly where your money is going before we start.
Yes, you absolutely need special permits for an ADU in San Francisco, including planning approval and building permits from the Department of Building Inspection. The city has specific zoning ordinances and design review processes for ADUs, which can be complex. We handle all the necessary paperwork and navigate the San Francisco permitting process for you. This includes ensuring your design complies with local setback requirements, height limits, and historic district guidelines if applicable.
Yes, converting your garage into an ADU is a common and often cost-effective option in San Francisco, provided it meets city requirements. Garage conversions are generally quicker and less expensive than building a new detached ADU because the structure is already there. You'll still need to address issues like foundation upgrades, insulation, new utility connections, and ensuring proper ventilation for San Francisco's climate. We assess your existing garage to determine feasibility and handle all necessary structural and permitting work.
