ADU Construction in Belmont
What Is an ADU and Why Build One in Belmont?
Accessory Dwelling Units (ADUs) — sometimes called granny flats, in-law units, or backyard cottages — have become one of the most popular ways for Belmont homeowners to expand their living space and increase property value.
An ADU is a self-contained secondary living space built on your property in Belmont. It can be detached, attached to your main home, or converted from an existing structure like a garage or basement. Designed right, an ADU provides flexibility, functionality, and long-term value — whether you use it for family, guests, or as an additional income stream. Living in Belmont, you know space is at a premium. That’s why so many residents are turning to ADUs.
Why ADUs are a smart investment in Belmont:
Additional Living Space: Perfect for aging parents, adult children, or visiting guests. Belmont families love the setup — close but still their own space.
Rental Income: Generate consistent income with a long-term or short-term rental. In Belmont, near Carlmont Village or along Ralston Avenue, that extra income helps.
Increased Property Value: Boost your home’s resale potential and market appeal. Homes near Notre Dame de Namur University or off Alameda de las Pulgas see a nice bump.
Multi-Generational Living: Keep family close while maintaining independence. We’ve helped Belmont families in the Twin Pines area set this up beautifully.
Sustainability: Smaller footprints, energy-efficient systems, and modern materials. Belmont’s eco-conscious homeowners really appreciate this.
