Project Overview 
Request: 
The applicant is requesting a Special Use Permit (SUP) to allow the combined gross floor area 
of all detached accessory buildings or structures to exceed 100% of the gross floor area of the 
primary building in the Single Residence 43 (RS-43) District, as well as a second SUP to allow 
an accessory structure to exceed the height of the primary residence. 
The existing primary residence contains approximately 4,608 square feet of gross floor area, 
while the proposed detached accessory structures would total approximately 9,924 square feet 
in combined gross floor area. In addition, the proposed RV garage will reach a height of 
approximately 22’-4”, which is 1’-10” taller than the primary residence. 
Site Context 
General Plan:  
• 
The Placetype for the project site is Rural Residential and the Growth Strategy is 
Conserve. 
• 
Single-family residential is identified as a principal land use in the Rural Residential 
Placetype. 
Planning Sub Area:  
The property is also within the Lehi Sub-Area. Goals for future development in this sub-
area include preservation of the historic and rural character of the area. Per the Lehi 
Sub-Area Plan, future development is intended to be communities of semi-rural 
residential and agricultural uses. The existing residence complies with the Lehi Sub-
Area Plan’s intent for semi-rural residential and agricultural uses to be maintained 
without conflict from commercial, industrial, or high-density residential development. 
Zoning:  
• 
The project site is zoned Single Residence 43 (RS-43).

[3] 
Surrounding Zoning & Use Activity: 
The proposed project is compatible with surrounding land uses, which includes low-intensity rural 
development.

Site History: 
• 
November 16, 1974: City Council annexed 1,394± acres, including the project site, into 
the City of Mesa and subsequently established Single Residence 43 (RS-43) zoning 
(Ordinance No. 672). 
• 
February 3, 2026: Development Services Department staff issued approval of a building 
permit that included a new 1,217 square foot attached RV garage, new 362 square foot 
front covered patio, and removal of an existing 558 square foot sunroom on the rear of the 
residence and replacement with a new 1,286 square foot rear patio (Building Permit No. 
PMT25-23363). 
Project/Request Details 
Site Plan: 
• 
Building Design: The proposed project consists of three pre-engineered metal buildings 
located in the rear yard. The applicant proposes a 50’x150’ RV garage, a 25’x60’ carport, 
and 20’x40’ BBQ ramada. The scale, placement, and design of these structures are 
consistent with development patterns commonly found within the Lehi area, which is 
characterized by rural residential properties with larger accessory structures and outdoor 
storage amenities. 
• 
Building Size: Per MZO Section 11-30-17(A)(4) of the MZO, the combined gross floor 
area of all detached accessory buildings or structures, shall not exceed 100% of the gross 
floor area of the primary building, unless approved by a Special Use Permit. Per the site 
plan submitted, the applicant is requesting that all detached structures on the property not 
exceed a total of 215% of the gross floor area of the primary building. 
• 
Building Height: The existing primary building (single-residence) has a height of 20’-6”. 
The proposed RV garage will have an overall height of 22’-4”, exceeding the height of the 
home by 1’-10”.

[4] 
Special Use Permit No. 1: 
The first SUP request is to allow the combined gross floor area of all detached accessory 
buildings or structures to exceed 100% of the gross floor area of the primary building in the RS-
43 District. 
Per Section 11-70-5(E) of the City of Mesa Zoning Ordinance, the Board of Adjustment shall find 
the following criteria are met for approval of a SUP: 
1. Advances the Goals and Objectives of and Consistency with the General Plan and 
other Plan/Policies: The proposed accessory buildings are consistent with the Rural 
Residential Placetype identified in the Mesa 2050 General Plan, which supports larger 
residential lots with low-density development patterns, detached structures, and rural 
character. The request allows for accessory structures that are common to rural residential 
properties, including storage, hobby, workshops, and accessory structures that support 
the functional use of larger residential lots. The proposed project maintains the low-
intensity residential character envisioned by the General Plan and is compatible with 
surrounding RS-43 development patterns where detached accessory buildings are 
common. The request does not increase residential density or introduce commercial or 
incompatible land uses. 
2. Consistency with the Zoning District Purposes: The proposed increase in accessory 
building area conforms to the goals and purposes of the Single Residence District and is 
consistent with the development standards of the RS-43 zoning designation. The property 
is large enough to accommodate the detached structures without reducing setbacks, open 
space, or separation between buildings. The accessory structures remain secondary to 
the primary residence and do not change the rural residential character of the property. 
3. Project Impact: The proposed accessory buildings and structures are appropriately 
scaled and located in compliance with all applicable development setback standards and 
are not expected to appear overbearing within the rural residential context. 
4. Adequate Public Facilities: The City of Mesa utilities and public infrastructure are 
available to serve the proposed project. 
Special Use Permit No. 2: 
The second SUP request is to allow a detached accessory structure to exceed the height of the 
primary building in the RS-43 District.  
Per Section 11-70-5(E) of the City of Mesa Zoning Ordinance, the Board of Adjustment shall find 
the following criteria are met: 
1. Advances the Goals and Objectives of and Consistency with the General Plan and 
other Plan/Policies: The proposed height increase for the detached accessory structure 
is consistent with the Rural Residential Placetype and the Mesa 2050 General Plan, which 
encourage development patterns that preserve rural character and allow flexibility for 
larger residential properties. Taller detached accessory structures, including workshops, 
garages, RV storage buildings, and agricultural-style buildings, are common within the 
Lehi Sub-Area and are characteristic of the area’s established rural residential 
development pattern. The request supports the functional use of the property while 
maintaining the low-density residential character envisioned by the General Plan and 
reflected throughout the Lehi Sub-Area.  
2. Consistency with the Zoning District Purposes: The proposed 22’-4” accessory 
structure is consistent with the RS-43 District. Although the request would allow the

[5] 
accessory structure to exceed the height of the primary residence, the proposed structure 
remains below the maximum permitted building height of 30 feet for primary structures in 
the RS-43 District. Taller detached accessory structures, including workshops, garages, 
RV storage buildings, and agricultural-style buildings, are common within the Lehi Sub 
Area and reflect the area’s established rural residential character.  
3. Project Impact: The proposed accessory buildings and structures are appropriately 
scaled and located in compliance with all applicable development setback standards and 
are not expected to appear overbearing within the rural residential context. 
4. Adequate Public Facilities: The City of Mesa utilities and public infrastructure are 
available to serve the proposed project. 
 
Required Notification 
The applicant provided notification letters to surrounding property owners within 150 feet of the 
project site, informing them of the public hearing.  
Staff received two phone calls and an email in opposition to the Proposed Project. One caller 
expressed concern that the sports field identified on the site plan could potentially be utilized as 
a motor track. A second caller also emailed and expressed concern over the overbearing size of 
pre-engineered buildings and commencement of construction prior to Board approval.  
Conditions of Approval 
Staff recommends approval of the Special Use Permits, subject to the following conditions: 
1. Compliance with the final site plan as submitted. 
2. Compliance with all applicable City development codes and regulations. 
Section 11-70-5 of the MZO allows for a revocation process if any condition, stipulation, or term 
of the approval of the SUP has been violated.  In addition to the conditions of approval above, 
approval of the SUPs is conditioned on the information provided by the applicant at the public 
hearing and in the application (including any accompanying narrative and other supplemental 
materials) not being false or materially misleading at the time of approval.
