SECTION 31: would continue to prohibit fluorescent signs and roof line lighting but would allow the use of neon, regardless of whether or not the neon lighting is exposed. Currently, only unexposed neon lighting (with protective covering) is allowed in the county. SECTION 32: relates to Sections it and 12, and comprises the substantive part of an initiative put forward by the Affordable Housing Advisory Committee to allow small, accessory dwelling units as accessory uses to single family residences. The proposal is not limited to producing small, affordable, presumably rental, dwelling units; it would also allow homeowners the opportunity to create legal "mother-in-law" units or units occupied by care -givers. Allowing such units, especially in existing neighborhoods, raises several concerns, including: possible increase in density in single family neighborhoods - a multi -family type of use in a single-family zoned area - "crowding" of single-family sites To address these concerns, staff has drafted specific land use criteria, which restrict accessory units as follows: 1. Density: - The overall size of accessory dwelling units is limited and, therefore, should not result in a significant increase in people living on a residential site. In essence, accessory dwelling units are not "full-sized" dwelling units. No accessory dwelling unit would be allowed on under- sized lots. Current lot size standards provide a density "cushion", whereby maximum allowable densities cannot be attained in a standard subdivision layout containing standard sized lots. 2. Multi -family type use: The accessory unit is tied to the single-family unit by common ownership. The exterior facade of an accessory unit (except a garage unit) must be similar to the single-family residence. Only one doorway entrance is allowed to be visible from the street. These criteria should help ensure that the development on the lot will appear to be one single family residence. 3. Crowding of the site Normal maximum lot coverage (by building area) and minimum open space requirements will apply. Therefore, the quantity of site development (building area and impervious area) cannot exceed what is already allowed for a single family residence. It should be noted that ordinances from other jurisdictions (municipalities in California; Gainesville and Orlando, Florida) were reviewed and used as a basis for developing accessory dwelling unit criteria. The county has the option to attach to the proposal more restrictive criteria, including: 11 SEPBOOK 87 PAU634 17 199
