Atherton ADU Construction
What Is an Atherton ADU and Why Build One?
Accessory Dwelling Units (ADUs) — sometimes called granny flats, in-law units, or backyard cottages — have become one of the most popular ways for Atherton homeowners to expand their living space and increase property value. And honestly, it’s no surprise. With Atherton’s large lots and quiet tree-lined streets, there’s often plenty of room to add a standalone unit without losing your backyard.
An ADU is a self-contained secondary living space built on your property. In Atherton, you might tuck it behind your main house near the corner of Alejandra Avenue, or convert that oversized garage off Selby Lane into a stylish one-bedroom. Whether it’s detached, attached to your main home, or converted from an existing structure like a garage or basement, an ADU gives you flexibility. Here’s what that means for you: more space for family, more options for guests, and a serious boost to your property’s long-term value.
Why ADUs are a smart investment in Atherton:
Additional Living Space: Perfect for aging parents, adult children coming back home, or visiting guests from out of town. We’ve seen many Atherton families use ADUs for multi-generational living — it keeps everyone close but still gives them their own space.
Rental Income: Generate consistent income with a long-term or short-term rental. With Atherton’s premium location near Silicon Valley, there’s always demand for quality housing.
Increased Property Value: Boost your home’s resale potential and market appeal. In Atherton’s competitive real estate market, an ADU can set your property apart.
Multi-Generational Living: Keep family close while maintaining independence. We hear this a lot: “We want my mom nearby, but not in the same house.” An ADU solves that beautifully.
Sustainability: Smaller footprints, energy-efficient systems, and modern materials. Plus, Atherton’s climate means you can often design with natural ventilation and light — lowering your utility bills.

We bring organization, creativity, and hands-on management to each ADU project in Atherton. No two lots are the same — and we treat each one with the care it deserves.
Here’s how we make it simple and stress-free for Atherton homeowners:
Atherton Site Evaluation & Feasibility Study
Before design begins, we assess your Atherton property to identify the best placement, size, and layout for your ADU. We’ll look at things like setbacks near Walsh Road or utility access off Stockbridge Avenue.

Discuss potential layouts, design ideas, and budget expectations tailored to your Atherton lifestyle.
