Fifty-Fifth Legislature, Second Regular Session
residential zoning; park model trailers
Purpose
Prohibits a county from adopting or imposing any regulation that prohibits or restricts, if all other standards regarding lot coverage and setback requirements have been met, the use of a park model trailer for a single-family residence on a residential lot or as an accessory dwelling unit.
Background

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).
There is no anticipated fiscal impact to the state General Fund associated with this legislation.
