New accessory dwellings in Alameda County come in several forms: detached structures, junior ADUs carved from existing homes, or converted garages. We manage everything from zoning research to occupancy permits, ensuring your unit meets county code and market expectations.

Neighborhoods across Alameda—from Oakland to Fremont to the Tri-Valley—have different density rules and parking requirements. We know the details for your specific area and plan your ADU accordingly.

Detached ADUs typically offer the most flexibility and resale appeal, especially in suburban Alameda County neighborhoods with larger lots.

A junior ADU (JADU) adds a smaller rental or accessory unit by splitting an existing dwelling. Perfect for narrow lots or when a full detached structure isn't feasible, JADUs create income without major site disruption.

We handle the interior reconfiguration—separate entrance, kitchen, bathroom, living space—while maintaining structural and fire-safety codes that Alameda County enforces.

Once framing and systems are complete, we install hardwood, vinyl, or tile flooring tailored to your unit's purpose and your property's climate. Alameda County's mild weather suits a range of finishes.

Flooring choices affect rental appeal and durability. We help you select durable, attractive materials that fit your timeline and budget, and install them to last.

New windows improve insulation, security, and curb appeal. Quality siding protects the structure and enhances visual cohesion between your main home and the ADU.

We match materials and styles to your home's aesthetic and choose products rated for Alameda County's coastal salt air and seasonal temperature swings.

Oakland and Berkeley properties often have smaller lots and dense neighborhoods, requiring creative JADU or vertical design. Fremont, San Leandro, and Hayward offer more room for detached ADUs.

We tailor designs and workflows to your neighborhood's character. Whether you're in a close-knit urban pocket or a suburban cul-de-sac, we know how to build efficiently and respectfully.
