In 2009, Council directed staff to develop a program to process applications, issue building permits and inspect unapproved dwelling units to ensure the health and safety of the individuals occupying the dwelling. Unrecorded dwelling units are separate living quarters (typically for rent and added to an existing home) where there is no official record of a building permit or inspection. City ordinance requires buildings, containing two or more dwelling units, to be approved by the City and issued a Certificate of Occupancy. By getting a Certificate of Occupancy before June 16, 2011, owners can save thousands of dollars in impact fees. After June 16, 2011, not only will owners be required to obtain the Certificate of Occupancy for the additional dwelling unit, but will also face impact fees in the $10,000-$12,000 range. Owners do have the option to re-convert the property back to a single-family dwelling.
