5. Operational Aspects of Use: 
 
Once operational, the facility will support full-scale manufactured home production with the following attributes: 
 
• 
Production of manufactured homes via two independent lines 
• 
Onsite fabrication of components such as cabinetry, countertops, and chassis 
• 
Use of adhesives, paints, and insulation systems consistent with modern home manufacturing 
• 
Exterior staging of completed units on asphalt rear yard prior to shipment 
• 
Integration of Owner-Furnished, Owner-Installed (OFOI) equipment, including weld jigs, CNC systems, 
dust collectors, forklifts, and paint booth systems 
 
Anticipated number of employees:  
 
• 
For Day 1 operations: approximately 228 employees (half capacity) 
• 
At maximum capacity: 455 employees 
• 
With both production lines active, Cavco anticipates utilizing around 80% of its maximum 
manufacturing capacity 
 
Shift schedule: one operational shift 
Employee parking: 465-stall surface lot 
Waste collection and recycling: Refuse and recyclable materials will be handled by Parks and Sons of Sun City. 
 
6. Parking Strategy and Waiver Request 
 
The project proposes surface parking designed to align with the operational realities of Cavco’s El Mirage 
Manufacturing Facility. Based on the anticipated maximum workforce of approximately 455 employees, the 
conceptual site plan currently provides 465 parking spaces to accommodate peak future staffing. At initial 
occupancy, the facility will employ approximately 228 employees (about half capacity). When both production 
lines are active, Cavco anticipates operating at roughly 80% of maximum staffing, resulting in an estimated 372 
employees on site during peak shifts. 
 
The City of El Mirage has authorized the project team to proceed with a Request for Design Exception to reduce 
the total number of required parking spaces. This request is supported by the following factors: 
 
• 
The facility is a single-user, shift-based operation with predictable staffing levels and minimal visitor 
traffic. 
• 
Customer or retail traffic is nonexistent, as all production and assembly occur within a secured, 
climate-controlled manufacturing environment. 
• 
A significant portion of the building’s ground-level square footage will be occupied by manufactured 
homes under construction, further reducing the functional intensity compared to generalized industrial 
uses. 
• 
The reduced parking plan will minimize unnecessary paving and impervious surface area, aligning with 
sustainable site design practices. 
 
The Design Exception is intended to right-size the parking supply to match the facility’s operational needs while 
maintaining adequate circulation, emergency access, and capacity for future growth.

Development Services Department 
Monday August 11, 2025

We look forward to working with City staff to finalize the Design Exception and ensure the parking supply is right-
sized to the facility’s actual needs while maintaining adequate circulation, emergency access, and future 
flexibility. 
 
 
7. Proposed Building/Structure Heights: 
 
• 
The primary manufacturing building and other vertical structures will reach a maximum height of 
approximately 56 feet to the top of the highest parapet. 
 
 
8. Proposed Infrastructure: 
 
Water & Wastewater Infrastructure: 
 
• 
Internal looped water distribution system for water and fire services connecting to the existing water 
line in Joe R. Ramirez Road 
• 
Business sewer connection to the existing sewer interceptor in Joe R. Ramirez Road 
 
Utilities and Services: 
 
• 
Water – EPCOR 
• 
Wastewater – EPCOR 
• 
Electrical – Arizona Public Service (APS) 
• 
Communications – Cox and/or CenturyLink 
• 
Refuse – Parks and Sons of Sun City 
• 
Natural Gas – Southwest Gas 
• 
Police & Fire – City of El Mirage 
 
Onsite Systems & Equipment: 
 
• 
Full automatic sprinkler system installed in accordance with NFPA 13 throughout the facility 
• 
Central compressed air system and utility trenches to distribute services to production line points-of-
use 
• 
Fall protection and multiple overhead crane lifting infrastructure 
• 
Dust and fume collection systems with code-compliant suppression 
• 
Roof system engineered for solar panel load and overhead cranes 
 
 
9. Conditional Use Permit – Outdoor Storage of Manufactured Homes 
 
This application includes a request for a Conditional Use Permit (CUP) to allow the outdoor storage of completed 
manufactured homes in the rear portion of the Cavco El Mirage facility site. The storage area is essential to 
facility operations, providing temporary staging space for units that are finished and awaiting shipment or 
transport. 
 
Outdoor storage is proposed only for fully assembled, factory-built homes that are ready for delivery. The homes 
will be stored in a designated asphalt-surfaced rear yard on the South, Southeast, and Southwest portions of 
the site, behind the primary manufacturing building.

Development Services Department 
Monday August 11, 2025 
Page 5 
 
 
 
The storage area will be fully screened by an 8-foot-high concrete masonry unit (CMU) wall along the front 
(North) side facing Joe R. Ramirez Road with chain-link fence that wraps around the remaining perimeter of the 
site, consistent with zoning ordinance requirements. The West, South, and East property lines are interior lot 
lines within the PAD zoning and do not face a public way. No storage will occur in the front yard visible from Joe 
R. Ramirez Road, with exception of Display Model Homes as shown on the enclosed Site Plan. 
 
This use supports the core manufacturing function of the site and meets the intent of the Employment/Industry 
(EI) zoning district and PAD00-08-01 by enabling efficient logistics and streamlined product movement. The 
following considerations further support the CUP request: 
 
• 
Compatibility: The site is within an industrial district (I-2) and surrounded by similar or complementary 
uses. The stored units are not active inventory or raw materials, but completed homes staged for a 
limited time. 
 
• 
Screening and Visual Impact: The 8-foot-high opaque CMU wall facing North toward W Joe R Ramirez 
Road and perimeter chain-link fencing along the three interior lot lines will prevent visibility from public 
rights-of-way or adjacent properties, minimizing visual and aesthetic impacts.   
 
• 
Traffic and Access: Deliveries and outbound shipments will be managed internally with circulation 
coordinated to prevent congestion or disruption to public streets. 
 
• 
Safety and Operations: The homes will be stored in a stable, unoccupied condition. No utilities will be 
active in the units during storage. Fire access and emergency vehicle clearances will be maintained 
throughout the rear yard. 
 
We respectfully request approval of the CUP as part of this application and are prepared to coordinate with staff 
on any conditions of approval related to site screening, storage limits, or layout adjustments. 
 
 
10. Proposed Phasing: 
 
The project is anticipated to be developed in a single phase to allow for unified commissioning and streamlined 
startup of manufacturing operations. If construction or permitting constraints arise, limited phasing may occur 
but will not affect the overall operational functionality upon completion. 
 
 
11. Planning Staff Coordination: 
 
Following coordination with the City of El Mirage planning staff (specifically Jose A. Macias), we were advised 
that a formal solar glare study is not required at this stage of review. Per the planner’s direction, this narrative 
serves to affirm that the rooftop solar Photovoltaic (PV) system will be designed and located to avoid glare 
impacts on Luke Air Force Base flight paths. Measures such as appropriate panel tilt, anti-reflective coating, 
and solar layout design will ensure no adverse impacts on air traffic or pilot visibility. 
 
 
12. Other Pertinent Information: 
 
• 
Hazardous Materials: The project will store and use materials typical of a homebuilding facility (e.g., 
adhesives, paint, and sealants). All hazardous materials will be stored in designated areas compliant 
with local fire and environmental safety codes.

See attached APPENDIX B – HAZARDOUS MATERIALS INVENTORY & COMPLIANCE SUMMARY, for more 
information. 
 
 
• 
Combustible Materials & High-Piled Storage Considerations: 
 
Cavco anticipates storing significant quantities of combustible building materials such as lumber, 
plywood, and OSB sheathing used in the production of manufactured homes. These materials will be 
stored in four dedicated open Materials Storage Structures (1–4), each ranging from approximately 
10,500 to 12,000 square feet with 30-foot building heights, as shown on the enclosed Site Plan. These 
structures will be constructed of pre-engineered metal and are separated from the main manufacturing 
building by a minimum of 25 feet to the rear of the site. 
 
Storage racks within these open storage structures will exceed 12 feet in height, which constitutes 
high-piled combustible storage per applicable fire codes. As such, it is anticipated that these buildings 
will be required to be equipped with automatic sprinkler systems and designed in accordance with the 
applicable provisions of the 2018 International Fire Code (IFC) Chapter 32 – High-Piled Combustible 
Storage, adopted by the City of El Mirage. While final sprinkler system design will be as a deferred 
submittal, Cavco is committed to full compliance with fire protection regulations, including coordination 
with the El Mirage Fire Marshal to confirm hazard classifications, aisle spacing, storage layouts, and 
suppression requirements. 
 
• 
Security: The site will include perimeter fencing, a controlled access gate system, and both interior and 
exterior surveillance cameras. 
 
• 
Sustainability: Rooftop solar panels are integral to the energy strategy, reducing grid reliance and 
aligning with Cavco’s long-term sustainability goals. 
 
• 
Design Excellence: The facility aims to achieve a 30-year useful life with durable exterior materials such 
as tilt-up concrete, pre-cast systems, or PEMB are under consideration. The final design will prioritize 
durability, performance, and aesthetic alignment with Cavco’s brand.
