Fast, Reliable General Contractor Across San Bernardino
Hiring a general contractor in San Bernardino means finding a team that understands the city’s intersecting demands – dense older lots, wildland-urban interface fire codes, and century-old framing that hides surprises behind stucco. Key Step Construction manages full-scope remodels and renovations across 92401, 92402, 92403, and 92404, so you get one contract, one schedule, and one point of accountability from the roof down to the foundation. Noel Garrity and our crew have worked jobs from the foothill corridors near the 92407 boundary down to the older westside grid, and we know what the building department and the Santa Ana wind season both demand. If you’re planning a kitchen overhaul, an ADU, a full exterior replacement, or a room addition in San Bernardino, call (855) 382-0824 for a free estimate and a straight conversation about scope.
Why Key Step Construction Is San Bernardino’s Preferred General Contractor Company
General contracting in San Bernardino is not a copy-paste operation. The city splits into two distinct construction worlds – the fire-prone north and foothill zones where WUI Chapter 7A requirements govern roofing, vents, and defensible space, and the older central and westside neighborhoods where single-wall framing and original plumbing lurk behind the stucco. Our team carries both sets of code knowledge into every quote, which means fewer surprises at inspection and no rework billed back to you.
We also understand how tight San Bernardino lots change project logistics. Staging materials on a 50-foot-deep lot in the 92405 corridor means planning deliveries around street parking and coordinating with neighbors before a dumpster ever shows up. That local awareness is built into our written line-item quotes, not tacked on after the fact. Homeowners who work with General Contractor teams that only visit San Bernardino occasionally miss these details – and their schedules and budgets show it.
Noel Garrity and Key Step Construction carry a curated roster of 50+ vetted material brands across cabinetry, countertops, roofing, windows, siding, hardscaping, and plumbing fixtures. That depth matters when a project spans multiple trades and you want real choices instead of a single-vendor take-it-or-leave-it situation. For San Bernardino homeowners, that means picking KraftMaid cabinets for a 1920s bungalow kitchen or Cambria quartz for a newer foothill build without juggling five separate suppliers.

Hire a General Contractor in San Bernardino
Hire a General Contractor in San Bernardino when the job spans more than one trade or touches structural, plumbing, or electrical systems. A full kitchen remodel in San Bernardino typically runs $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a home addition $45,000 – $130,000. Those numbers shift based on era of construction, WUI compliance requirements, and access constraints on your specific lot.
Kitchen and Bathroom Remodels
Older San Bernardino bungalows in 92401 and 92404 often hide galvanized supply lines and knob-and-tube wiring inside original walls. We coordinate with city inspectors to bring rough-in work up to code before closing anything up. Material allowances are built around brands like KraftMaid, Cambria, Kohler, and Moen so your budget reflects real choices, not placeholder allowances you’ll regret halfway through.
Room Additions and ADUs
A room addition or garage conversion in San Bernardino frequently triggers WUI review, especially on north-side and foothill parcels. We handle the Chapter 7A ember-resistant vent and Class A assembly requirements as part of the permit package, so the project doesn’t stall at final inspection. ADU construction in San Bernardino runs $90,000 – $220,000, and we support prefab systems through partnerships with Abodu and Cover where that approach fits the lot and timeline.
General Contractor Services in San Bernardino
General Contractor Services in San Bernardino span interior remodeling, exterior replacement, hardscaping, and ADU construction. A paver patio in San Bernardino runs $3,500 – $11,000, a roof replacement $8,000 – $20,000, and window replacement $4,500 – $15,000. We provide one contract covering every scope, so you don’t coordinate a roofer, a window crew, and a hardscape installer separately.
Exterior and Fire-Hardening Work
San Bernardino’s wind-and-fire interface means exterior work isn’t cosmetic. We replace roofing with GAF, CertainTeed, or Owens Corning systems installed to the brand’s spec and the city’s WUI requirements. James Hardie siding, PGT impact windows, and ember-resistant vent upgrades are standard recommendations on foothill and north-side jobs, and we tie each product warranty into the final handoff package.
Hardscaping and Site Work
Tight lots limit where materials can live during a job. On a recent 1920s single-wall bungalow in the 92405 corridor, our crew staged Quikrete and Sakrete bag goods in the driveway and scheduled deliveries around the street’s morning parking crunch. A daily punch list kept the site clean and the neighbors informed, which matters when you’re working six feet from the property line. Belgard, Unilock, and Techo-Bloc pavers carry their own product warranties, adding an extra layer of post-installation protection.
Trusted Brands We Service in San Bernardino
Our team installs and warranties systems from manufacturers who back their products with real coverage – GAF and CertainTeed roofing, James Hardie siding, PGT windows, Belgard hardscaping, and Quikrete and Sakrete concrete products for San Bernardino site work. For prefab ADU projects, our partnerships with Abodu and Cover let us pull permits and prepare foundations while the factory builds the module, which shortens the on-site timeline for tight San Bernardino lots. One contractor. Every system.

AfterCommon General Contractor Problems We See in San Bernardino Homes
- Hidden galvanized plumbing and knob-and-tube wiring: Century-old bungalows in 92401, 92404, and 92405 still hold original supply lines and cloth-wrapped wiring behind the stucco. Opening a wall without budgeting for upgrade work causes mid-project change orders, which is why we write allowances for these retrofits into the initial quote.
- Chapter 7A WUI surprises on remodels: A substantial remodel on a foothill parcel can trigger ember-resistant vent and Class A roofing requirements even if you’re not doing a full exterior replacement. Contractors who don’t build this into the permit package face failed inspections and costly rework at final sign-off.
- Tight-lot staging and parking conflicts: San Bernardino’s older neighborhoods have narrow streets and shared driveways. Bidding a job without accounting for limited staging and notification logistics pushes the schedule and burns the contingency budget. We map material handling before we bid.
- Party-wall notice and noise ordinance violations: Dense neighborhoods mean shared walls and close neighbors. Skipping proper notice or running loud work outside city-allowed hours triggers complaints and stop-work orders that delay your draw schedule. We handle the notifications and keep the site clean from day one.
Pricing for General Contractor in San Bernardino, CA
San Bernardino pricing reflects the cost of working across two code environments – WUI fire hardening on the north and foothill sides, and retrofit-heavy single-wall construction in the older central and westside ZIPs. These ranges are based on what we’ve built in this market, not national averages.
| Project Scope | Typical San Bernardino Cost Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
What moves the number: era of construction, whether Chapter 7A compliance applies, lot access for staging, and material selections. A 1960s tract home in 92408 with open lot access costs less to remodel than a 1920s bungalow in the downtown grid where every wall may hide something. We quote with a written line item format and fixed scope language so the price you approve is the price you build under.

FAQs About General Contractor in San Bernardino
Yes, a kitchen remodel that touches plumbing, electrical, or structural framing requires a permit through the City of San Bernardino Building and Safety division. If your home is in a WUI zone, the permit review may also trigger Chapter 7A exterior requirements. Call (855) 382-0824 and we’ll map the full permit path for your specific project before you sign anything.
If your parcel sits on the north side or in the foothill corridor, a room addition may require Class A roofing assemblies, ember-resistant vents, and fire-rated exterior materials under Chapter 7A – even when you’re not touching the existing roof. We build these requirements into the permit package and the quote so you don’t get hit with rework at final inspection.
San Bernardino’s older neighborhoods often leave little room for material staging, so we plan deliveries around street parking restrictions and keep bag goods and materials consolidated in a designated zone. On a recent 1920s bungalow job in the 92405 corridor, we staged in the driveway and scheduled deliveries to avoid the morning parking crunch. A daily punch list kept the street and the neighbors informed.
We deliver written notice to adjacent property owners before work starts on shared-wall properties, and we keep work within San Bernardino’s noise ordinance hours. If a project requires access to a neighbor’s side yard or a shared wall inspection, we coordinate that contact directly. Neighbor conflicts stop work orders, so we front-load the communication.
Yes, garage conversions in San Bernardino typically run $30,000 – $80,000 and ADU construction $90,000 – $220,000, depending on whether you build site-framed or use a prefab system. We support Abodu and Cover prefab ADUs and handle the foundation, utilities, and permit coordination for both approaches. Estimates are free – call (855) 382-0824.
