  • How long does it take to permit and build an ADU in Santa Rosa?

    Most ADU projects in Santa Rosa take roughly 6 to 12 months from permit submittal to move-in, depending on plan complexity and City review times. Prefabricated or pre-approved ADU plans can shorten the permit phase. Hilario Construction manages the full timeline, from design coordination through final inspection.

  • What size and setback rules apply to an ADU on a Santa Rosa lot?

    In Santa Rosa, detached ADUs can be up to 1,200 square feet and generally require a 4-foot setback from rear and side property lines, though lot size and zoning can affect the specifics. State law has also reduced or eliminated setback requirements for ADUs built within existing structures. We review your parcel before any work begins to confirm what applies.

Permit and utility connection fees are separate and vary by jurisdiction. We provide detailed project estimates based on your specific lot and goals.
