ARIZONA STATE SENATE
Fifty-Fifth Legislature, Second Regular Session
AMENDED
residential zoning; park model trailers
Purpose
Requires a county to allow for the use of a park model trailer as an accessory dwelling unit for use as a single-family residence in outlined locations. Requires the park model trailer to be on a semi-permanent or permanent foundation that has utility connections and meets all drainage, floodplain, sanitary sewer or septic waste disposal requirements and all other zoning standards.
Background
A county board of supervisors may adopt a zoning ordinance in order to conserve and promote the public health, safety, convenience and general welfare. Zoning ordinances must show the zoning districts designated as appropriate for various classes of residential, business and industrial uses and must provide for the establishment of setback lines and other plans providing for adequate light, air and parking facilities and for expediting traffic within the districts. Zoning ordinances may also establish the percentage of a lot that may be covered by buildings and the size of yards, courts and other open spaces (A.R.S. § 11-811).
If a political subdivision adopts a comprehensive zoning ordinance
regulating the height of buildings, an airport zoning regulation applicable to
the same area or portion of the same area may be: 1) incorporated in and made a
part of the comprehensive zoning regulation; and 2) administered and enforced
in connection with the comprehensive zoning regulation (A.R.S.
§ 28-8466). A high noise or accident potential zone includes
property located in: 1) Luke Air Force Base in Maricopa county; 2) Davis-Monthan
Air Force Base in Pima county; 3) Yuma Marine Corps Air Station;
4) Laguna Army Airfield in Yuma county; 5) Libby Army Airfield in Cochise
county; and
6) outlined ancillary military facilities (A.R.S.
§ 28-8461).
There is no anticipated fiscal impact to the state General Fund associated with this legislation.
