What's Involved in Building a Junior ADU (JADU) in San Francisco?

A Junior ADU (JADU) is an independent living unit, no more than 500 square feet, created within the existing walls of a single-family home. It includes a cooking facility, a bathroom, and a separate entrance, but it doesn't need its own dedicated parking space. We handle everything from the initial design and permitting to the full build-out, making sure it meets all San Francisco's specific JADU requirements.

Our approach starts with evaluating your current home's layout to see where a JADU makes the most sense. We look at existing bedrooms, dens, or even underutilized spaces that can be converted efficiently. We then draw up plans that maximize the space while ensuring it's fully compliant with local codes – things like fire safety, accessibility, and utility hookups. We don't cut corners; we build it right the first time.

Building a JADU in San Francisco is a smart move because it increases housing density without needing new land. This is crucial in a city where space is at a premium. It also allows homeowners to generate rental income, helping with the high cost of living here. Plus, it's generally less expensive and faster to permit than a full ADU, making it a more accessible option for many.

Homeowners often worry about losing too much of their main house space or the complexity of the permits. We address this by designing JADUs that integrate smoothly, often with shared utility connections to simplify things. We also navigate the San Francisco Planning Department and Department of Building Inspection rules for you, so you don't have to deal with the red tape. You'll get a clear timeline and regular updates throughout the project.

Why Build a Junior ADU (JADU) in San Francisco?

Building a Junior ADU in San Francisco is a solid investment because it directly addresses the city's housing shortage and high rental demand. You're adding a legal, independent unit that can fetch significant rental income, helping you offset your mortgage or simply provide extra cash flow. It's a practical way to make your property work harder for you in a competitive market.

San Francisco's unique housing stock, with many older homes and Victorian-era buildings, often has unused or underutilized spaces perfect for JADU conversion. We understand these older structures, their quirks, and how to integrate modern amenities without compromising their character. We're used to working with the city's strict historical preservation guidelines where they apply.

JADUs are also a good option for multi-generational living or providing a private space for family members. With San Francisco's tight housing market, keeping family close by in their own independent unit is a big advantage. It gives them privacy while still being on your property, which is often a better solution than them trying to find their own place in this city.
