Local know-how, on your side.
Fremont's larger suburban lots are well suited to detached backyard ADUs, and steady demand across the city's districts makes added square footage valuable for both family living and rental.
Permitting in Fremont: Fremont handles ADU permits through its Community Development Department under California ADU law. Generous lot sizes in many neighborhoods favor detached units, while utility connections and impact fees are the main cost variables to scope early.
Whatever your Fremont lot allows, we scope it honestly, put the trades out to competitive bid, and manage the build from permit to keys — so you capture the value for up to 10% less than a markup contractor would charge.
