An accessory dwelling, guesthouse or second unit requires a parcel specific review of allowed uses, district and supplemental standards, prior approvals, density and building requirements. For unincorporated property start with ULDC Articles 3, 4 and 5 and obtain zoning confirmation or preapplication review. Check the intended occupancy or rental use, parking, utilities and septic capacity. Municipal rules are separate. The presence of an existing outbuilding or a Property Appraiser use code is not permission to create a dwelling.
