We work across all three Upland ZIP codes – 91784, 91785, and 91786 – and our General Contractor team handles everything from kitchen overhauls to full ADU builds without you ever having to play project manager.

What separates a smooth Upland remodel from a six-month headache isn’t the showroom choices. It’s what’s hiding inside the walls of a house built before 1980. We plan for that before we ever submit plans to the city.

Why Key Step Construction Is Upland’s Preferred General Contractor Company

Upland’s housing stock demands a contractor who knows the difference between a 1920s craftsman near the historic downtown core and a 1960s tract home with original galvanized plumbing. Our work across the city has taught us exactly where those differences live. On a recent job in 91786, we opened a 1950s ranch house to add a primary suite and found the original cast-iron drain lines corroded through and a 100-amp panel already maxed out. We wrote a change order for the undersized framing and failed waterproofing in the existing bath, priced it in writing, and got approval before touching the load-bearing wall. After inspection sign-off, we closed up with new rough-in and a clean punch list. That’s the standard approach on every Upland project we take.

Led by Noel Garrity, our team works from a simple rule: inspect first, price second, build third. No homeowner should learn about a code-triggered upgrade the hard way.

As a full-scope operation, we carry one contract across interior remodeling and exterior renovation. The same team managing your kitchen cabinets is also accountable for your roofing, siding, windows, and hardscaping. No subcontractor juggling, no finger-pointing between trades, no gaps in responsibility. When you call us about a material question or a schedule change, you get an answer from someone who already knows your project. That’s the single-contractor advantage, and it matters more on general contractor projects where mature lots and older structures create real complexity.

Construction Company in Upland

Construction Company work in Upland means structural change on a mature lot. That could be a room addition off the back of a 1970s tract home in 91785, a garage conversion in 91786, or a detached ADU on a foothill property in 91784. The lot sizes here are generous by Southern California standards, which is why addition and ADU work dominates the permit activity in this city. A home addition in Upland typically runs $45,000 – $130,000, and an ADU construction project lands between $90,000 and $220,000 depending on site conditions, utility work, and what the fire zone triggers.

Upland sits at the base of the San Gabriel Mountains, and much of the buildable land has been developed for decades. Greenfield subdivisions aren’t the norm here. The work we do is remodel-and-rebuild on existing lots, which means we’re always accounting for what’s already underground and inside the walls.

Addition and ADU Builds

Expansive clay soils are common across Upland, and that changes how we approach foundation and slab work on additions. A standard flatland approach can lead to cracking and failed inspections. We size footings and slab reinforcement for the actual soil conditions, not the ones a contractor from Rancho Cucamonga assumes apply everywhere.

In the 91784 foothill zone, even a modest room addition can trigger fire-resistant construction and defensible-space requirements that a nearly identical project a mile downhill in 91786 would not. That distinction catches out-of-town contractors at permit time, and it’s why we review fire-zone status before we ever draw plans.

Garage Conversions and Detached Structures

Many Upland homes have detached garages, and converting one into livable square footage typically runs $30,000 – $80,000. The older the garage, the more likely we’re dealing with a slab that was never engineered for a conditioned space. That’s an allowance item we write into the contract up front so you’re not surprised when the concrete saw comes out.

Remodeling Contractor in Upland

Remodeling Contractor work in Upland usually starts with a kitchen or bathroom, then expands once the house tells us what it needs. A kitchen remodel here runs $14,000 – $45,000, though a smaller galley kitchen can be done for $9,000 – $20,000. Bathroom remodels typically land between $9,000 and $28,000, with smaller baths starting around $5,000. Those ranges assume we’re dealing with the unknowns Upland homes throw at us, not just the finish work.

What opens up these older Upland homes actually turns up is often the same list: outdated wiring, undersized or damaged framing, failed waterproofing, and code upgrades that a permit triggers once walls are open. This is the single biggest reason a remodel quote moves. Our approach is to inspect first and write allowances into the contract, so any surprise is priced and approved in writing before we touch it.

Kitchen and Bath Renovations

We offer real material choices, not a single-vendor take-it-or-leave-it offer. Cabinet lines like Upland and Wellborn, engineered stone from Cambria and Silestone, and plumbing fixtures from Kohler, Grohe, Moen, and Delta mean your budget and priorities steer the selections. We’re authorized to work with 50+ industry-leading material brands across every renovation category.

Whole-Home System Upgrades

One contractor, every system. When a Upland remodel opens a wall and finds a maxed-out electrical panel or corroded cast-iron drain lines, we coordinate the upgrade under the same contract. No separate electrician quotes, no plumbing sub you have to chase. The project stays on one schedule with one accountable party.

Trusted Brands We Service in Upland

For Upland projects we regularly work with Quikrete and Sakrete for foundation and hardscape pours, and we partner with Abodu for prefab ADU builds. These brands carry their own product warranties, which adds a layer of post-installation protection for homeowners. We also integrate Schluter waterproofing systems in showers and wet areas, because the details most contractors overlook are exactly where water damage starts. For Upland customers, having a contractor who stocks and services these systems locally means fewer supply-chain delays and faster turnaround on material questions.

Common General Contractor Problems We See in Upland Homes

• Undersized or maxed-out electrical panels. Many 1950s-1970s Upland homes still have 100-amp service, which doesn’t survive a modern kitchen or ADU addition. We include panel upgrades as a written allowance so the cost isn’t a shock after demo.
• Corroded cast-iron or galvanized plumbing. Homes in 91786 especially still carry original drain lines that are past their service life. Once walls are open, we scope the lines and price any replacement before cutting further.
• Foothill fire-zone requirements in 91784. Ember-resistant vents, fire-rated siding, and defensible-space landscaping can be mandatory on a room addition in the high fire severity zone. We check the Cal Fire and city overlay before plans go to the city.
• Failed waterproofing in showers and baths. We tore open a 1980s tract home in 91785 to find a shower pan that had been leaking into the subfloor for years. The fix was not optional, and because it was scoped as an allowance, the homeowner approved it the same day without project stoppage.
