Fast, Reliable General Contractor Across Upland
Hiring a General Contractor in Upland means finding someone who understands that a remodel near the 210 freeway and a foothill ADU off Mountain Avenue are two completely different jobs. We’re Timberline Contractors, led by Nelson Fung, and we’ve built our reputation on managing the full scope of a project, from structural work to the final cabinet pull. If you’re planning a kitchen remodel, room addition, or detached ADU in Upland, call (866) 253-5808 for a free estimate. We bring the showroom to the project and the accountability to the contract.
Why Timberline Contractors Is Upland’s Preferred General Contractor Company
Upland homeowners tend to ask harder questions than most. That’s because the city’s patchwork of building codes, soil conditions, and architectural styles rewards people who plan properly. Our work across the 91784, 91785, and 91786 zip codes has taught us that a fixed-price quote without a soil report on the north side is a guess, not a bid. We scope jobs the way they’ll actually be built. When a homeowner near Foothill Boulevard wants to convert a garage, we’re already thinking about the foundation tie-in and whether the existing slab has the depth for an occupancy permit. That’s local knowledge that saves money and months.
Nelson Fung has built Timberline around a simple principle: one contractor, every phase. Homeowners in Upland who have tried juggling a tile sub, a roofer, and a county inspector for an ADU know the coordination burden. We absorb that. The General Contractor in Upland work we do spans interior remodel, exterior envelope, and outdoor living, and the brand partners we’ve curated, including Toto, American Standard, and Delta, mean material decisions get made faster with fewer surprises.
Styles & brands we work with







Residential General Contractor in Upland
A Residential General Contractor in Upland handles the structural and finish work that turns an aging ranch house into a home that fits the way you live now. Most of the homes we work on in the central and southern flats were built between the 1950s and 1970s, which means single-story framing, older electrical panels, and floor plans that close off the kitchen from the living space. A kitchen remodel in Upland typically runs $14,000 to $45,000, depending on whether you’re moving plumbing, replacing the electrical service, or working around load-bearing walls. A room addition in Upland generally falls between $45,000 and $130,000, and that range reflects the differences between a simple bump-out on a flat central lot and a hillside addition in 91784 with fire-code upgrades and deeper footings.
Full Scope Remodels
When a Upland homeowner wants a whole-home remodel, we start with the systems nobody sees. That includes the panel, the supply lines, and the drainage. We then move to the finishes, and our access to 50-plus brand partners means a client can pair a Kohler kitchen faucet with a Delta shower system and an American Standard vanity without waiting on a supplier to special-order anything.
Additions on Challenging Lots
Additions on Upland’s north-side hillside lots require more than framing. The expansive alluvial soil in 91784 often demands an over-excavated foundation or a post-tension slab, and the wildland-urban-interface code adds ember-resistant vents and non-combustible siding requirements. We price these items as line items from the start, not as change orders after excavation begins.
Hire a General Contractor in Upland
If you’re going to hire a General Contractor in Upland for an addition, ADU, or major remodel, look at how the contractor scopes the permitting path before you look at the bottom number. On an acreage parcel off Mountain Avenue, the plan-check authority might be San Bernardino County, not the city of Upland. That changes the inspection schedule, the septic and well setback requirements, and the draw schedule you use to fund the work. A garage conversion in Upland typically runs $30,000 to $80,000. An ADU in Upland runs $90,000 to $220,000, and that range accounts for foundation work, utility trenching, and fire-code compliance on hillside sites.
Permitting and Setbacks
Before we quote an ADU or addition on an Upland acreage lot, we confirm whether the property falls under city or county jurisdiction. That single determination changes which agency signs off on plumbing, electrical, and septic, and it changes how long the job takes. We pull permits ourselves and keep an inspection-ready file on site.
Material Allowances That Hold
We document every allowance in writing before we start. For a recent detached ADU on an acreage parcel off Mountain Avenue in 91784, the homeowner wanted a 900-square-foot unit with a full kitchen. The lot sits on county jurisdiction for septic and well setbacks, so we coordinated with San Bernardino County Environmental Health rather than city plan-check. The expansive soil required an over-excavated foundation with a post-tension slab. We scoped the rough-in for plumbing and electrical early, set a draw schedule tied to county inspection sign-off, and used KraftMaid cabinets and a Cambria countertop to keep the finish timeline predictable. The job closed with zero change orders because the allowances were documented before demo day.
Trusted Brands We Service in Upland
Upland homeowners want specific products, not generic catalog picks. That’s why we keep direct relationships with manufacturers like Toto, American Standard, and Delta. When a client near San Antonio Heights wants a Toto toilet with a specific rough-in dimension or a Delta shower system with a particular valve configuration, we can source it without a middleman marking it up. For Upland jobs, we also maintain local parts accounts so a trim kit or a replacement cartridge can arrive quickly. Built to last, not built to flip, means the fixtures we install are the ones you’ll still be using in twenty years.

AfterCommon General Contractor Problems We See in Upland Homes
- Expansive soil on foothill lots: In 91784, the alluvial fan clay expands and contracts with moisture, which can crack a standard slab and force a foundation redesign if the soil report comes back late. We order the geotechnical work before we finalize a fixed price.
- Wrong permitting path on acreage: A north-side property outside city limits has septic and well setbacks governed by San Bernardino County, not the city of Upland. Missing that in the scope of work stalls the draw schedule and delays every trade.
- Historic overlay surprises near downtown: Parcels near Euclid Avenue can trigger historic-preservation review for exterior changes, and skipping that check means plan-check rejection and rework of load-bearing or exterior details on an early-1900s Craftsman or Spanish Colonial Revival house.
- Fire-code upgrades on hillside additions: Homes against the San Gabriel foothills face wildland-urban-interface requirements for ember-resistant vents, tempered glass, and non-combustible siding. A quote that ignores these gets changed after the first plan-check comment.
Pricing for General Contractor in Upland, CA
Upland’s construction costs are shaped by the split between flat, established tracts in the south and hillside acreage in the north. Here’s what we see in the current market:
| Project | Typical Upland Range |
|---|---|

| Home Addition | $45,000 – $130,000 |
| Garage Conversion | $30,000 – $80,000 |
A hillside ADU in 91784 with a post-tension foundation and fire-code upgrades lands on the higher end. A garage conversion on a central Upland lot with an existing concrete slab falls toward the lower end. We give written, line-item quotes so you can see exactly where the money goes.

FAQs About General Contractor in Upland
It depends on the lot’s jurisdiction. An acreage parcel in 91784 outside the city of Upland boundary is typically governed by San Bernardino County for septic, well setbacks, and building plan-check, while a parcel inside the city limits goes through Upland’s building department. We verify the jurisdiction before we quote, because it changes the inspection schedule and the draw timeline. Call (866) 253-5808 and we’ll check your parcel.
Expansive alluvial clay on foothill lots in 91784 can require an over-excavated foundation, a post-tension slab, or both, which adds $10,000 to $30,000 over a standard slab depending on the soil report and the structure size.
A hillside addition in Upland’s wildland-urban-interface zone requires ember-resistant attic vents, non-combustible or ignition-resistant siding, and tempered glazing on windows facing the foothills. These items should be in the quote from day one, not added after plan check.
Yes. A remodel on a parcel near Euclid Avenue in downtown Upland can trigger historic-preservation review, which affects exterior materials, window replacement, and structural changes. We prepare the drawings and documentation for that review and coordinate with the city’s planning staff before construction begins.
We write every allowance to a specific product or installation standard, in writing, before the contract is signed. That means a Cambria countertop allowance is for a specific Cambria tier, and a KraftMaid cabinet allowance is for a specific door style and finish. Then we hold to it.
