Arizona needs more homes at prices working households can afford. Cavco’s new El Mirage factory will expand the region’s ability to build them, and offers a look at how manufactured and modular housing could become a bigger part of the solution.
The Phoenix-based company has broken ground on a 39-acre campus designed to produce factory-built single-family homes. For real estate investors, the story reaches beyond a new industrial building: it is an investment in changing how housing gets delivered.
What Cavco Is Building
- Facility: Approximately 616,000 square feet in El Mirage.
- Products: HUD-code manufactured homes and modular single-family homes.
- Production: One initial production line, with the ability to add a second.
- Design: A temperature-controlled facility incorporating advanced manufacturing techniques.
- Timeline: Targeting operations by mid-2027, subject to permitting and construction progress.
- Reach: Intended to serve Arizona and surrounding states.
- Unannounced details: Total development cost, final staffing, and annual production capacity.
This is a factory that can supply homes to multiple communities. The number ultimately added to Arizona’s housing inventory will depend on orders, available sites, and completed installations.
Modular and Manufactured Homes: What Is the Difference?
Both use factory production, but they follow different construction standards.
| Housing type | How it works |
|---|---|
| Manufactured | Built to the federal HUD construction and safety code, then transported to its site. |
| Modular | Built in factory sections and assembled on-site, meeting the applicable state and local building codes used for site-built homes. |
That distinction matters for permitting, financing, and resale. “Factory-built” describes the production approach; it does not mean every home is the same product or qualifies for the same loan.
How Factory Construction Can Improve Affordability
Building inside a factory can reduce several expenses that make conventional construction difficult to predict:
- More efficient labor: Crews work at organized stations with materials and equipment nearby.
- Less material waste: Repeatable designs and precise fabrication can reduce offcuts and errors.
- Fewer weather interruptions: Enclosed production protects much of the building process from outdoor conditions.
- Overlapping work: Site preparation and home production can happen at the same time.
- Repeatable quality checks: Standard processes can catch problems before delivery.
Those efficiencies can lower construction costs and shorten schedules. Savings still depend on the design, factory workload, transportation distance, and installation requirements.
We previously covered Phoenix apartments built from shipping containers. That is a different construction approach, but it reflects the same search for more efficient ways to deliver housing. Each approach needs to prove its value through completed-project costs and performance.
A $124,000 Home Still Needs Land and Infrastructure
Cavco’s representative cited an average manufactured-home price of roughly $124,000, excluding land. That figure is not a guaranteed price for homes from the new factory or a complete move-in budget.
Buyers and investors need to establish whether their quote includes:
- Land acquisition or ongoing lot rent.
- Transportation, foundation work, and installation.
- Permits, site preparation, and utility connections.
- Driveways, drainage, and required improvements.
- Financing, taxes, insurance, and ongoing maintenance.
The useful comparison is the total cost of an occupied home—and its monthly ownership cost.
That connects directly with our coverage of Arizona’s HB 2999 and infrastructure financing. Improving the building process addresses one expense. Roads, water, sewer, and financing remain part of the affordability equation.
What the Future of Modular Housing Could Look Like
The opportunity is broader than producing familiar floor plans in larger numbers. Digital design, automated fabrication, and better coordination between factories and installation crews could make smaller homes, backyard residences, and multifamily projects easier to deliver.
Some modular builders are already using robotics and digitally coordinated production. Those innovations demonstrate the direction of the industry; they should not be assumed to be features of Cavco’s El Mirage plant.
Scaling successfully also requires a dependable pipeline of orders. Factories carry substantial fixed costs, and inconsistent demand can undermine expected savings.
Homes still need places where they can be installed. Our coverage of Phoenix’s middle housing changes explores the complementary issue of allowing more housing choices within existing neighborhoods. Production capacity, usable land, infrastructure, and workable approvals all need to come together.
What Arizona Rental Investors Should Watch
Factory-built housing could create opportunities to deliver rentals at a lower total development cost. It could also give renters more choices and help some households become homeowners sooner.
For investors, that means:
- Compare complete development bids, including site work and installation.
- Confirm the exact product’s placement, financing, and insurance requirements before committing.
- Evaluate local rents and competing housing options rather than assuming a new home guarantees a premium.
- Consider durability, energy performance, repair access, and warranty service alongside purchase price.
Cavco’s investment is a promising step toward producing more attainable homes. Its long-term contribution will be measured by homes completed, households served, and the full cost of living in them.
