Overview 
Prescribes specified requirements for municipal ancillary use and multifamily residential 
housing. Directs a municipality of 200,000 or more but less than 500,000 persons to allow 
hotel use and multifamily residential housing as an allowed ancillary use in a zoning district 
that permits light industrial use without requiring any type of application needing a public 
hearing if the ancillary use is located within an international headquarters campus. 
History 
The planning agency may, or if directed by the legislative body must, prepare specific plans 
based on the general plan and drafts of such regulations, programs and legislation as may in 
the judgment of the agency be required for the systematic execution of the general plan.  
Specific plans may, in addition to recommended zoning ordinances and subdivision 
regulations, include regulations determining the location of buildings and other 
improvements with respect to existing rights-of-way, floodplains and public facilities and 
regulations of the use of land, buildings and structures, the height and bulk of buildings and 
structures and the open spaces around buildings and structures, among others (A.R.S § 9-
461.08). 
The objective standards required by a municipality for a multifamily residential development 
are required to include 1) a municipal site plan review and approval process, including review 
by any utility provider impacted by the proposed development, 2) adequate public sewer and 
water service for the entire proposed development, 3) compliance with all applicable building 
and fire codes, 4) that the existing buildings are economically or functionally obsolete, 5) that 
existing buildings are located on a parcel or parcels that are at least one acre in size but not 
more than 20 acres in size and 6) a set-aside of 10% of the total dwelling units for either 
moderate or low-income housing or any combination of the two or at least 20 years after the 
initial occupation of the proposed development. The developer may set aside more than 10% 
at the developer's sole discretion (A.R.S. § 9-462.10). 
Provisions 
1. Requires a municipality with a population of 200,000 or more persons but less than 
500,000 persons to allow hotel use and multifamily residential housing as an allowed 
ancillary use on land that is vacant as of the date of the application for the allowed 
ancillary use in a zoning district that allows light industrial use without requiring any 
type of application requiring a public hearing if the ancillary use:

building before the municipality grants a certificate of occupancy for the international

building before the municipality grants a certificate of occupancy for the international

for the building within five years after granting the certificate for ancillary use building. 
(Sec. 1)
