Upside ADU builds multigenerational adus in Loomis, Placer County, for a $1,000 deposit with transparent fixed pricing and inspection-tied payments. A typical Loomis multigen adu runs $157,500–$466,200 all-in, and we permit it through the Town of Loomis / Placer County Building Division end to end.
Loomis rules that affect a multigen adu
Loomis multigenerational builds are designed single-level and accessible — zero-step entry, wider doorways, curbless showers — so parents or adult kids live independently next door. Placer County permits these like any detached or attached ADU.
Local permitting: Loomis reviews ADUs through the Town of Loomis with Placer County building support. Rural-residential zoning means larger minimum lots, frequent septic and well systems, and tree-protection review — all of which we scope before pricing a detached build.
That's the multigen adu-specific picture. For the full Placer County rulebook — every setback, height, and owner-occupancy detail — see our Sacramento-region ADU rules guide, and learn how the build type works statewide on our multigenerational adu page.
