Benson ADU Builders is the ADU company Moreno Valley homeowners call when they want a written price before any work starts and a 365-day guarantee behind every nail. Most Moreno Valley homes sit on lots large enough for a detached accessory dwelling unit, and the city’s flat, sun-baked terrain makes prefab panel delivery simpler than in hillside communities nearby. Whether you’re planning a backyard rental unit off Alessandro Boulevard or a granny flat near Sunnymead Ranch, our crews coordinate from the Inland Empire office and work locally throughout Moreno Valley. Call (903) 568-7222 and you’ll get a live person, not a voicemail loop.
Why Moreno Valley Homes Are Different
Moreno Valley’s housing stock skews toward 1980s and 1990s single-story ranches on generous lots, which changes how we approach every ADU and addition. Those older homes often have panelized electrical service that needs a subpanel upgrade before a detached unit can be powered properly, and many sit on slab foundations that require careful grading work before we pour a new ADU pad. Summer temperatures routinely cross 100 degrees, so we schedule concrete pours and panel lifts in the early morning and spec roofing materials that can handle the relentless Inland Empire sun. Wind is another factor: the Santa Ana gusts that sweep through the Pass area mean we anchor prefab modules with extra tie-downs. HOA rules in neighborhoods like Sunnymead Ranch can add a design-review step, though many Moreno Valley lots fall outside HOA jurisdiction entirely. The good news is the terrain works in your favor: flat lots mean shorter utility runs and fewer surprise excavation costs than hillside cities to the west.
Our Main Moreno Valley Services
Most Moreno Valley homeowners reach out to us for one of three things: a detached ADU in the backyard, a full home addition that expands the main house, or a single room addition that turns a cramped floor plan into something livable. Each service has its own page with detailed pricing and timelines.
ADU Builders in Moreno Valley
An ADU in Moreno Valley changes the math on your property: it’s rental income, a place for aging parents, or a quiet workspace separated from the main house. We build both detached units and garage conversions, and because our crews work the city regularly, we know the lot dimensions and setback rules that dictate what fits where. Most Moreno Valley backyards can accommodate an 800 to 1,200 square foot detached unit without triggering a variance. Our role as ADU Builders in Moreno Valley starts with a measured site visit and a written price, not a verbal guess. You’ll see the number before anything gets signed.
Home Addition Contractor in Moreno Valley
A home addition expands the existing footprint, which in Moreno Valley usually means building out into a side yard or extending the back of the house. Older ranches from the 80s and 90s often have floor plans that can absorb a family room or a primary suite addition without touching rooflines we’d rather not disturb. We pull permits, match the existing stucco, and tie the new roof into the old one with the same flashing details we’d use on a brand-new build. As a Home Addition Contractor in Moreno Valley, Troy Eastman and our team put every line item in writing so the price doesn’t drift after demo day. That’s the whole point of the Benson approach.
Room Addition Contractor in Moreno Valley
A room addition is the focused version: one new space, one clear scope, one price. In Moreno Valley, we see a lot of homeowners who need a fourth bedroom, a dedicated home office, or a larger kitchen, and they don’t want to move to get it. The existing slab and roof structure usually dictate whether we extend the existing foundation or pour a new one, and we walk you through that choice before you spend a dollar. Our Room Addition Contractor in Moreno Valley page covers the exact sub-jobs and what they cost here. You’ll get a written quote that holds.

What pushes a Moreno Valley price up? Mostly site conditions: older electrical panels that need full replacement, utility trenches that cross concrete patios, and HOA design review where it applies. Prefab options like Cover and Dvele keep costs more predictable because the module price is locked before it leaves the factory. Every Benson estimate is a written line-item quote, and the price doesn’t change unless you change the scope. That’s the Relay Visibility Guarantee at work.
