Fast, Reliable General Contractor Across Rancho Cucamonga

If you’re planning a remodel, addition, or ADU in Rancho Cucamonga, you need a contractor who knows how this city actually approves work. Alder Contractors handles whole-home remodels, additions, and prefab ADUs across Rancho Cucamonga with one point of accountability from first permit to final inspection. Nelson Ibarra leads our team, and we’ve built our process around the review sequence Rancho Cucamonga homeowners genuinely face: HOA architectural approval first, then San Bernardino County permitting, then construction scheduled so nothing sits half-finished.

Why Alder Contractors Is Rancho Cucamonga’s Preferred General Contractor Company

Most homeowners in Rancho Cucamonga don’t need a builder who only knows new construction. They need someone who understands the tract homes, the HOAs, and the county review quirks that make every project here different from a job in Fontana or Upland. Our team has worked through dozens of Rancho Cucamonga remodels, additions, and garage-to-ADU conversions, including foothill lots in 91737 and 91739 where grading and brush-clearance conditions change the scope entirely. Nelson Ibarra personally reviews every Rancho Cucamonga estimate before it goes out, because a sloped-lot addition near the San Gabriel foothills should never be quoted like a flat-lot job in the valley.

We carry full general contracting license coverage and handle the submittal packet for you: HOA architectural application, city planning review, and county building permits. When a committee bounces a submittal over stucco color or roof pitch, we’re the ones who revise and refile. You don’t chase the board, and you don’t sit on hold with the county. That single-contract accountability is what makes us different from the patchwork approach most Rancho Cucamonga homeowners are trying to escape. Call (833) 467-7020 and ask for a written line-item estimate.

Remodeling Contractor in Rancho Cucamonga

A Remodeling Contractor in Rancho Cucamonga typically manages kitchen and bath gut-outs, whole-home refreshes, and second-story build-outs on the 1980s-to-early-2000s stucco tract homes that dominate 91701, 91729, 91737, and 91739. We pull permits through San Bernardino County, coordinate every trade under one contract, and work from a written draw schedule so you know exactly what gets done before the next payment is due. Most Rancho Cucamonga homeowners call us when an original kitchen has 30-year-old cabinets, or when a growing family needs a bonus room above the garage.

Kitchen and bath gut-outs

A Rancho Cucamonga kitchen remodel typically runs $14,000 to $45,000 depending on cabinet grade, countertop selection, and whether walls move. Bathroom remodels fall between $9,000 and $28,000. We carry Cambria and Silestone quartz options, plus Kohler and Grohe fixtures, so you choose finishes without a separate designer middleman.

Additions and build-outs

Room additions in Rancho Cucamonga run $45,000 to $130,000. Second-story build-outs on existing ranch or two-story frames are common here because most lots are built out and there’s nowhere to expand laterally. We handle the structural engineering, the HOA submittal, and the county sign-offs in sequence.

Licensed General Contractor in Rancho Cucamonga

A Licensed General Contractor in Rancho Cucamonga is the difference between a project that passes review and a project that stalls in committee. Our license covers interior remodeling and exterior construction trades, which means we can manage your roofline, your stucco, your windows, and your hardscape under one contract instead of four separate vendors with four schedules. In Rancho Cucamonga specifically, we schedule around the HOA architectural calendar so demolition doesn’t start before the committee approves paint color, roof pitch, and visible massing.

Permit and submittal management

We file the HOA architectural submittal, the city planning review, and the county building permit in order. That sequencing matters here. Starting demo before the HOA approves your roof pitch or stucco shade is how walls end up open for weeks while a committee debates trim color.

Whole-home scope

From a kitchen remodel to a full exterior re-skin with James Hardie siding and GAF roofing, we run the job as one project. You get one contract, one point of accountability, and one call when questions come up. That’s the whole point of hiring a licensed general contractor instead of juggling subcontractors yourself.

Trusted Brands We Service in Rancho Cucamonga

We build with materials from manufacturers that Rancho Cucamonga homeowners actually trust and that HOA committees actually approve. For hardscaping, we install Belgard and Cambridge Pavers on Rancho Cucamonga patios and driveways. For fences, we carry Master Halco and Jerith, both of which hold up under the summer UV and dry Santa Ana conditions here. For countertops and fixtures, Cambria, Silestone, Kohler, and Grohe are in our catalog, so you’re not limited to what a big-box store decides to stock. Because we order directly from suppliers who serve the Inland Empire, turnaround on custom-order materials for Rancho Cucamonga jobs is faster than going through a designer middleman.

Common General Contractor Problems We See in Rancho Cucamonga Homes

  • Sloped foothill lots with deferred drainage work. Homes in 91737 and 91739 along the northern edge sit against the San Gabriel foothills, and a flat-lot drainage plan simply doesn’t work there. We see additions that were quoted without slope-stability review, then hit grading and brush-clearance conditions mid-project.
  • Original 1980s and 1990s windows and stucco. Most tract homes here were built between 1970 and the early 2000s, and the intense inland sun has punished original windows, stucco, and roofing. A remodel that doesn’t address the building envelope often just covers up a problem that reappears in two summers.
  • HOA submittals filed after permits. This is the most common failure mode in Rancho Cucamonga. The tract committee rejects a paint color or roof pitch while the walls are already open, and the project stalls. We file the HOA submittal first, then the county permit.
  • Remodel quotes without written allowances. If your contract doesn’t spell out appliance and finish allowances, those selections become change orders that stall the punch list. We write allowances into every Rancho Cucamonga estimate so the number you approve is the number you pay.

What Rancho Cucamonga Customers Say

Trusted by homeowners across Rancho Cucamonga and surrounding areas.

★★★★★

"Allowances in the contract were realistic rather than artificially low to make the bid look good."

Miguel Vargas · Verified customer
★★★★★

"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."

Brooke Ziegler · Verified customer
★★★★★

"Excellent build. Costs came in about six percent over the original contract, driven mostly by material price movement during the build, which he documented each time."
