Fresno conditions

Building adu for Fresno conditions

California's statewide ADU law limits how far Fresno can restrict you, which is exactly why Fresno is one of the strongest ADU markets in the country, but Title 24 energy and seismic detailing still decide whether plan check goes smoothly. In Fresno's Central Valley heat, a compact unit overheats quickly, so insulation, shading, and right-sized cooling are designed in from the start.
