Frequently Asked Questions

An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family residential lot. Building one in San Francisco lets you add valuable living space, generate rental income in a high-demand market, or house family members close by. It's a smart way to maximize your property's potential without buying more land. Plus, San Francisco has specific rules designed to encourage ADU construction, making it a good investment.
Building an ADU in San Francisco typically takes 12-18 months from initial design to final inspection, including the permitting process. The design and permitting phase can often take 6-10 months due to city review times and specific San Francisco planning requirements. Once permits are secured, construction usually wraps up in about 4-8 months. We work to keep things moving as quickly as the city allows.
The typical costs for an ADU project in San Francisco range from $250,000 to $500,000 or more, depending on size, finishes, and site conditions. This includes design, permits, and construction. Foundation work can be more complex and costly on some San Francisco hillsides. We provide a clear breakdown after our initial site visit, so you know what to expect for your specific project.
Yes, you absolutely need permits from the San Francisco Department of Building Inspection (DBI) to build an ADU. This includes planning approval, building permits, and often other departmental sign-offs like public works. We handle the entire permitting process for you, navigating the specific local regulations to ensure your ADU is fully compliant and legal. Don't try to build without them; it'll cost you more in the long run.
Yes, converting an existing garage into an ADU is a common and often cost-effective option in San Francisco. This type of conversion can sometimes streamline the permitting process compared to new construction, especially if the existing structure is sound. We'll assess your garage's condition and advise on what's needed to meet San Francisco's building and safety codes for a habitable living space. It's a great way to use existing square footage.
