SDW Construction makes adding an accessory dwelling unit simple, affordable, and stress-free for Bay Area homeowners. Whether you need space for aging parents, adult children, or rental income, our licensed team handles permits, design, and full construction with 20 years of expertise. Here’s what an ADU from SDW Construction can do for you:
ADUs don't require buying new land, major infrastructure, elevators, or structured parking, making them one of the most cost-effective housing options in California.
Turn your backyard into a steady income source by renting to long-term tenants or short-term guests. As anADU contractor in Richmond, we know how pricy it is to live here.
We use proven wood frame construction methods that cost significantly less than new multifamily developments while delivering the same quality.
ADUs let extended families live near each other while maintaining separate, independent living spaces.
Our ADUs provide as much space as newly-built apartments and condos, perfect for couples, small families, young adults, or seniors.
Give your aging parents the flexibility to stay on your property as they need more care, without sacrificing their independence.
Whether you’re converting a garage or building a brand-new backyard cottage, SDW Construction delivers expert ADU design and construction throughout the Bay Area. Here’s a look at the types of ADUs we build:
Stand-alone structures separated from the primary residence, offering maximum privacy and flexibility for family or renters.
Additions directly connected to the main house, perfect for keeping loved ones close while maintaining separate living space.
Transform existing space like a garage, storage room, basement, or attic into a fully functional living unit without the cost of new construction.
Units built on top of existing or new garages, making smart use of vertical space on your property.
