Summary of Strike-Everything Amendment to SB 1118

Overview

Allows the development of duplexes, triplexes, fourplexes and townhomes (middle housing) in areas deemed historic as outlined.

History

A city or town (municipality) with a population of at least 75,000, or through an ordinance incorporated into its development regulations must authorize zoning regulations for middle housing on lots zoned for single-family residential and any new development with at least ten acres of continuous land. Middle housing requirements do not apply to areas that: 1) are not incorporated; 2) lack sufficient urban services; 3) are not served by water and sewer services; 4) are not zoned for residential use; 5) are not incorporated and are zoned for planned urban development; 6) are covered under domestic water improvement districts and domestic wastewater improvement districts; or 7) are within the vicinity of a public or military airport (A.R.S. § 9-462.13).

Provisions

1.   Permits for middle housing to be developed in areas deemed historic by a municipality  or designated as historic on the National Register of Historic Places if the middle housing is designed to be compatible with the historic character, scale and setting of the surrounding area. (Sec. 1)

2.   Stipulates the following for middle housing that is developed in areas deemed historic:

a.   a municipality can require that middle housing comply with the historic preservation or design standards adopted by the municipality or the United States Secretary of Interior's Standards for the treatment of historic properties;

b.   a municipality can regulate standards including building height, massing, lot coverage, setbacks, roof form, site layout and overall building volume; and

c. middle housing cannot exceed the maximum building height, lot coverage or floor area ratio that is allowed by applicable zoning regulations that were adopted prior to January 1, 2025. (Sec. 1)

3.   Allows a municipality to require an administrative site plan review for confirming compliance with applicable standards, unless stricter zoning regulations are required by applicable historic preservation standards. (Sec. 1)

4.   Forbids municipalities from requiring a public hearing, variance, conditional use permit, special permit or other discretionary approval process for developing middle housing in areas deemed historic. (Sec. 1)

5.   Prohibits middle housing from being developed on a site where a National Register of Historic Places structure or structure designated as historic by a municipality was demolished unless the demolition was necessary because of conditions that constitute danger to public health, safety and welfare. (Sec. 1)

6.   Makes technical and conforming changes. (Sec. 1)
