What drives ADU cost up or down in Galt?
Galt runs roughly 4% below the central-Sacramento baseline, making it one of the more cost-efficient places in the region to add an ADU.
Galt lots: Liberty Ranch is newer-tract flat with room for a full detached unit. Central Galt's older deep lots and standing garages are where the cheapest conversions in the county tend to be.
Local permitting: Galt reviews ADUs at its own Building Division on Sacramento County standards (4 ft setbacks, 16 ft height), and the near-total lack of HOA overlay keeps the process simple. Liberty Ranch brings larger flat tract lots; central Galt's older parcels usually come with a detached garage ready to convert.
The single biggest cost lever is size: keeping a unit under 750 sq ft exempts it from local impact fees. Site conditions (slope, soil, utility runs) and finish level move the rest.
