As demand for flexible, affordable housing continues to surge across California, Green Group Remodeling, a leading Bay Area design-build contractor, is helping homeowners navigate recently updated Accessory Dwelling Unit (ADU) regulations that expand opportunities to add livable space legally and efficiently.

Recent legislation, including changes to California’s ADU laws in 2024, has removed many barriers to building detached or attached ADUs, easing setbacks, parking requirements, and minimum lot size rules. These updates empower homeowners to create backyard cottages, in-law units, or rental apartments with fewer permitting delays and greater design flexibility.

At Green Group Remodeling, we’ve found that ADUs are one of the best ways to add housing options and build property value here in the Bay Area. However, many homeowners don’t realize that local and state regulations work together, and getting a permit-approved ADU still requires careful planning and expertise.

Under current statewide rules, homeowners can build detached ADUs up to 800 square feet by right, with certain conditions allowing up to 1,200 square feet depending on lot size and local ordinances. Junior ADUs (JADUs) of up to 500 square feet can also be built within existing homes. These options provide a pathway for multi-generational housing, passive income, or expanded living space without the need to relocate.

Green Group Remodeling emphasizes that while state law protects ADU construction, local jurisdictions may still impose design guidelines, height limits, or infrastructure requirements. Homeowners should always work with a licensed contractor familiar with both state and local codes to ensure a compliant, streamlined build.

If you’ve been wanting to build an ADU on our property but aren’t sure where to start or how to navigate the permitting and zoning process, Green Group Remodeling can help! Get a free consultation at https://greengroupremodeling.com/additional-dwelling-units or call (925) 217-8784 today!
