Saratoga Springs requires a building permit for basement finishes. For apartments, the city runs a registration and occupancy-permit system: a separate exterior entrance is required, plus one paved parking stall behind the front setback, owner occupancy, and 30-day-minimum rentals. The city maintains a zone map of where internal apartments are allowed — we verify your parcel first.
In most single-family homes, yes — Utah law requires most cities to allow one internal accessory apartment, subject to city requirements like owner-occupancy, parking, and registration. Saratoga's registration system means an apartment done right is fully defensible — and one done without registration risks fines. We design it to registration standards and match you with a crew who files it properly. Details on basement apartments.
About six weeks from demo to final inspection for a standard finish; 8–10 weeks for a full apartment. You get the week-by-week schedule in writing before we start.
