Fast, Reliable General Contractor Across Grand Terrace
Most general contracting work in Grand Terrace involves opening up homes built between the 1950s and 1970s and finding what the original builders left behind. That’s where we come in. Alder Contractors handles whole-home remodels, room additions, kitchen and bath renovations, and ADU conversions across Grand Terrace, and we know the permitting path through San Bernardino County cold. If you’re planning a remodel in 92313 and want a contractor who inspects before bidding, call (833) 467-7020 for a free estimate.
Why Alder Contractors Is Grand Terrace’s Preferred General Contractor Team
Grand Terrace homeowners don’t have a city building department to walk plans through. Every permit goes through San Bernardino County, and on hillside lots along Blue Mountain, county reviewers dig into retaining walls, drainage, and foundation details far more than they do on flat valley floor jobs. We’ve worked that process enough to know what triggers a correction and what sails through. Our estimates account for that reality up front, which is why homeowners here keep referring us to neighbors on De Berry Street and Barton Road. Nelson Ibarra, who runs Alder Contractors, built the company around a simple idea: inspect first, price honestly, and never let a surprise kill a project.
We’re not a handyman service picking up small repair tickets. We’re a single-source General Contractor for mid-to-large renovations, which is exactly the kind of work Grand Terrace’s housing stock demands. When you call, you talk to someone who can walk you through scope, material selections from our 50+ brand portfolio, and what the county permit will require before we ever put a number in front of you.
Styles & brands we work with







Licensed General Contractor in Grand Terrace
A Licensed General Contractor in Grand Terrace means someone who pulls the San Bernardino County permits, schedules the inspections, and stands behind the work. We carry full general contracting coverage for interior remodeling and exterior construction, and we manage every trade under one contract. A kitchen remodel here runs $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a home addition $45,000 – $130,000. Those are real Grand Terrace ranges we’ve seen on projects across the city.
Pre-Inspection Before the Bid
Before we price anything, we open walls or at minimum inspect what’s accessible. On a 1962 stucco-and-wood-frame home off Blue Mountain Drive, our crew opened up a kitchen wall for a load-bearing removal and found cloth-wrapped wiring and undersized framing that had been patched over. We wrote a change order with allowances for the electrical rough-in and framing upgrades, priced it in writing, and got inspection sign-off from the county before closing up the walls. That kept the project on the draw schedule and kept the homeowner from eating an unplanned five-figure surprise.
Written Allowances Built Into Every Contract
We put allowances in the contract for exactly the things Grand Terrace remodels tend to uncover: outdated electrical panels, original plumbing that fails under load, and framing that doesn’t meet current code. When a surprise shows up, it’s already priced, approved, and documented. No tear-out that isn’t signed off first.
Residential General Contractor in Grand Terrace
A Residential General Contractor in Grand Terrace handles the work that turns an aging mid-century home into a current one. We manage kitchen and bath remodels, full interior renovations, exterior replacements including roofing, siding, windows, and doors, plus hardscaping, fencing, and ADU construction. An ADU in Grand Terrace runs $90,000 – $220,000 and includes everything from the county permit submission to the final inspection. We’ve installed ADU builds through Abodu, Dvele, and Mighty Buildings, which keeps timelines tighter than stick-built alone.
Whole-Home Scope From Roofline to Backyard
Most Grand Terrace homes are original stucco-and-wood-frame construction with aging systems. Our crews coordinate roofing with GAF and CertainTeed materials, James Hardie siding, PGT windows, and Therma-Tru doors under the same schedule and the same point of accountability. You’re not juggling four vendors and four calendars.
Seismic and Structural Upgrades
Older homes on the valley floor and up the Blue Mountain slopes often need foundation bolting, shear wall upgrades, and beam replacements when walls come down. Those are structural changes the county reviews closely. We handle the engineering, the permit, and the inspection in sequence.
Trusted Brands We Service in Grand Terrace
We stock and install from a portfolio of more than 50 name-brand manufacturers, which means Grand Terrace homeowners get real choices without the research burden. For hardscape projects we work with Belgard, Techo-Bloc, and Unilock pavers on patio and driveway builds. Kitchen remodels pull from Cambria and Silestone countertops, KraftMaid cabinetry, and Kohler or Grohe fixtures. Fencing runs through Master Halco and Jerith. We know which materials hold up under Inland Empire heat and Santa Ana wind cycles, and we keep turnaround tight for Grand Terrace customers because we’re based just down the 215 in Rialto.

AfterCommon General Contractor Problems We See in Grand Terrace Homes
- Bidding without opening the walls first. Contractors who price a remodel sight-unseen get burned when the walls come down and the cloth-wrapped wiring shows up. We inspect first, and we write allowances into the contract so the number doesn’t move without your signature.
- Skipping the county permit because there’s no city building department. Grand Terrace has no in-house permitting office, so every remodel permit runs through San Bernardino County. Miss that step and you’re looking at failed inspection sign-off and required tear-out on work you already paid for.
- Ignoring Blue Mountain hillside drainage and slope-stability requirements. County reviewers scrutinize retaining walls and foundation details on hillside lots. Winter rain and Santa Ana winds expose shortcuts fast, and a failed retaining wall is a five-figure correction.
- Trying to manage multiple subs without a general contractor. A kitchen remodel touches plumbing, electrical, framing, drywall, and finish carpentry. One missed sequence and the whole schedule slips. We handle the coordination so you don’t have to chase anyone.

FAQs About General Contractor in Grand Terrace
Yes, for nearly every remodel that touches structure, electrical, plumbing, or square footage, and the permit comes from San Bernardino County, not a city building department. We prepare and submit the plans, schedule the inspections, and stay on the job until final sign-off. Call (833) 467-7020 and we’ll tell you exactly what your scope triggers.
Plan on replacing it when walls open up for a remodel. Cloth-wrapped wiring, undersized panels, and ungrounded outlets are common in homes built during that era here, and the county will not sign off a remodel that leaves exposed original wiring in an inspected wall cavity. We build electrical upgrade allowances into the contract so it’s priced before you’re ever surprised by it.
We bring in a structural engineer early and design the retaining walls, drainage, and foundation details to meet county hillside standards. Santa Ana winds and winter rain stress graded slopes on the Blue Mountain edge, so we don’t skimp on drainage. That work gets priced in writing before any wall goes up.
Yes, garage conversions to ADUs are one of the most common projects we price in Grand Terrace, typically running $30,000 – $80,000 depending on the existing structure and whether you’re adding a bathroom and kitchen. We can also handle prefab ADUs through Abodu, Dvele, and Mighty Buildings for faster timelines. Call (833) 467-7020 for a site walk and a real number.
A change order is a written, priced document that covers work discovered after the contract is signed, like outdated framing or failed waterproofing, and it gets your approval before that work starts. Grand Terrace remodels on 1950s-era homes turn up surprises regularly, and a good change order keeps the project on budget and on schedule. We issue them for anything not covered by an existing allowance.
