ADU Construction in San Bruno
What Is an ADU and Why Build One in San Bruno?
Accessory Dwelling Units (ADUs) — sometimes called granny flats, in-law units, or backyard cottages — have become one of the most popular ways for San Bruno homeowners to expand their living space and increase property value. The truth is, with home prices what they are here, adding an ADU just makes sense.
An ADU is a self-contained secondary living space built on your property. It can be detached, attached to your main home, or converted from an existing structure like a garage or basement. In San Bruno, you’ll see them popping up in neighborhoods like Crestmoor, Rollingwood, and near Capuchino High School. Designed right, an ADU provides flexibility, functionality, and long-term value — whether you use it for family, guests, or as an additional income stream. We’ve seen it firsthand: a well-built ADU can transform how you live on your property.
Why ADUs are a smart investment in San Bruno:
Additional Living Space: Perfect for aging parents, adult children, or visiting guests. We’ve helped San Bruno families create space for everyone without moving out of the neighborhood they love.
Rental Income: Generate consistent income with a long-term or short-term rental. With San Bruno’s proximity to SFO and major employers, there’s always demand.
Increased Property Value: Boost your home’s resale potential and market appeal. Homes near San Bruno Park or downtown see major value jumps with a quality ADU.
Multi-Generational Living: Keep family close while maintaining independence. It’s common in San Bruno — we see it all the time on streets like Spring Avenue and Crystal Springs.
Sustainability: Smaller footprints, energy-efficient systems, and modern materials. Given San Bruno’s mild climate, we can design ADUs that keep utility bills low year-round.

Here’s how we make it simple and stress-free:
San Bruno Site Evaluation & Feasibility Study
Before design begins, we assess your property to identify the best placement, size, and layout for your ADU. In San Bruno, lot sizes vary — from compact plots near San Bruno Avenue to larger lots up in Skyline.
Evaluate zoning, setbacks, and utility access. San Bruno’s R-1 zones have specific rules we know inside out.
Review city regulations and lot constraints. We’ve worked with San Bruno’s planning department dozens of times.
Discuss potential layouts, design ideas, and budget expectations. Whether it’s a backyard cottage or a garage conversion, we tailor it to your San Bruno property.
