This district provides opportunities for low density detached single-family homes, accessory dwelling units, clustered and planned developments, mobile homes, manufactured housing and compatible uses such as day care and smaller residential care facilities. Bed and breakfast inns, and public and quasi-public uses may also be allowed in appropriate locations at the discretion of the city.
