Sponsor: Representative Parker B, LD 10
Committee on Natural Resources, Energy & Water
Overview
Prescribes restrictions for counties relating to building permits for single-family homes,
accessory dwelling units and detached garages.
History
A board of supervisors of a county is permitted to adopt a zoning ordinance in order to
conserve and promote the public health, safety, convenience and general welfare. Statute
outlines what can and cannot be included in zoning ordinance (A.R.S. §§ 11-811 and 11-812).
A county zoning ordinance can be enforced by means of withholding building permits for the
construction, reconstruction, alteration or use of any building within a zoning district covered
by the county zoning ordinance. A building permit is not required for repairs or improvements
with a value equal to or less than $500 (A.R.S. § 11-815).
County building code requirements do not apply to: 1) construction or operation incidental to
construction and repair to irrigation and drainage ditches of regularly constituted districts
or reclamation districts or to farming or other work on rural land for fire prevention purposes;
and 2) devices used in manufacturing, processing or fabrication normally considered to be
involved in the construction of energy, gas or other public utility systems (A.R.S. § 11-865).
Provisions
