Accessory Dwelling Units

The county’s zoning code permits internal, attached, and detached accessory dwellings by right in all districts that permit single-family residences, subject to use-specific standards (§3.4). These standards address units per lot, unit size, structure type, utilities, building separation, design, and permits and administration.

Outdoor Lighting

The county’s zoning code addresses outdoor lighting (§4.3); these provisions were adopted in 1981 to protect astronomical observation areas within the county. The ordinance divides lighting into 3 classes and the county into 3 zones based on the distance to astronomical observation areas. It establishes preferred lighting sources, addresses lamp types and shielding specifications, and total outdoor light output. It provides for light curfews; lists special requirements for outdoor advertising signs, service station canopies, and outdoor recreation facilities; and exempts airports and temporary holiday decorations. The ordinance describes lighting permit requirements and processes.
