Fast, Reliable General Contractor Across Riverside
If you’re searching for a General Contractor who understands Riverside’s older Craftsman homes and newer east-side tracts equally well, you’ve found the right team. San Mateo Construction handles whole-home remodels, room additions, and ADU construction across Riverside, with one accountable crew managing every trade from roofline to foundation. We know which materials hold up under 100°F+ Inland summers and which ones crack, fade, and fail within five years. Call (855) 901-7266 to talk through your project and get a free, line-item estimate.
Why San Mateo Construction Is Riverside’s Preferred General Contractor Company
Riverside homeowners hire us because we don’t treat a 1920s Craftsman in the 92506 core the same way we treat a 1990s tract home off Alessandro Boulevard. The city’s construction history spans four distinct eras within a few square miles, and each one has its own code vintages, foundation types, and failure patterns. Noel Carrington, who leads our team, has spent his career working across both the historic-rehab side and the modern production-building side of Riverside’s housing stock. That means we show up knowing which raised-foundation homes need seismic bolting and which slab-on-grade builds need WUI-compliant exterior assemblies.
Our Riverside customers consistently tell us the same thing: they wanted one contractor who could manage the whole scope without forcing them to coordinate three separate subs and a material supplier. That’s what we do. One contract, one schedule, one point of accountability. When a Riverside homeowner calls us about a kitchen remodel that’s really a kitchen-plus-roof-plus-window job, we don’t hand off the roofing and windows to someone else. We run the whole thing.
Styles & brands we work with







Hire a General Contractor in Riverside
Hire a General Contractor in Riverside when your project touches more than one trade, or when the home’s age and location mean the work has to satisfy seismic, fire-interface, and energy codes all at once. A full kitchen remodel in Riverside typically runs $14,000 – $45,000 depending on cabinetry, countertop material, and whether we’re moving plumbing or load-bearing walls. A bathroom remodel runs $9,000 – $28,000. A home addition lands between $45,000 and $130,000, and an ADU starts around $90,000 and can exceed $220,000 for a larger unit with premium finishes. Every estimate we write is line-itemed, so you see exactly where the money goes before we ever pull a permit.
Seismic and WUI-Compliant Scope
Older Riverside homes on raised foundations frequently need cripple-wall bracing and foundation bolting before we start the cosmetic work. Foothill-adjacent properties in 92503 and 92504 may also need ember-resistant vents, non-combustible siding, or Class A roofing assemblies to meet WUI rules. We build these requirements into the scope from day one, not as a change order later.
Remodeling Across Multiple Construction Eras
A downtown 92501 Victorian needs a different approach than a 1980s stucco build in 92505. We’ve pulled permits, opened walls, and fixed prior-owner work in both. You get a contractor who can match historic trim profiles and also spec a modern prefab ADU panel system in the same week.
General Contractor Services in Riverside
General Contractor Services in Riverside span everything from a single-room refresh to a whole-home gut-and-rebuild. The most common projects we take on are kitchen remodels, bathroom remodels, window replacements, roof replacements, room additions, and ADU construction. A typical window replacement in Riverside runs $4,500 – $15,000, impact-rated units run $8,000 – $25,000, and a full roof replacement runs $8,000 – $20,000 depending on the assembly we specify for your ZIP. If your home sits in a WUI-adjacent zone, the roof price will reflect the Class A assembly and ember-resistant venting the foothill corridor requires.
Exterior-to-Interior Scope Under One Contract
The same crew that re-roofs your Riverside home can replace the windows, rebuild the kitchen, and pour a new paver driveway. That coordination matters when a Santa Ana wind event exposes a roofing problem at the same time you’re planning an interior remodel. One schedule means fewer delays.

ADU and Addition Capability
Riverside’s ADU rules have changed a lot in the last decade, and we stay current on the city’s setback, height, and fire-access requirements. We build traditional stick-frame ADUs and also work with modern prefab manufacturers where that approach saves time and money. Either way, the unit meets current seismic and WUI code before final inspection.

Trusted Brands We Service in Riverside
We carry direct relationships with manufacturers that matter for Riverside’s specific climate and code demands. For roofing, we specify GAF, CertainTeed, and Owens Corning assemblies, with Tamko as a value-tier option where the budget calls for it. On windows, we install PGT impact-rated units, Therma-Tru doors, and CGI frames where coastal-spec glazing isn’t required but heat-cycling resistance is. For fencing and hardscape, we work with Boral and Master Halco product lines. Because we stock and source these materials frequently for Riverside jobs, we’re not waiting on a distributor three counties away when your project hits the framing stage.

AfterCommon General Contractor Problems We See in Riverside Homes
- Builder-grade galvanized fasteners failing under heat cycling. Riverside’s summer highs regularly top 100°F, and cheap galvanized hardware expands, contracts, and eventually shears or corrodes at the joint. We spec hot-dip galvanized or stainless fasteners on every roof and exterior assembly we touch.
- Standard sealants cracking within two to three seasons. The smog-trapping basin heat breaks down big-box store sealants fast. We use heat-rated commercial sealants on stucco joints, window flashing, and paver joints so the work doesn’t open up a year later.
- Raised-foundation homes with unbolted cripple walls. This shows up constantly in the downtown 92501 and 92506 core. Homes built before modern seismic codes often have no foundation bolting at all, and we add shear bracing and anchor bolts as part of the remodel scope before any finish work begins.
- Foothill homes missing WUI-required exterior details. In 92503 and parts of 92504, prior remodels sometimes skipped ember-resistant vents or used combustible siding where the code now requires non-combustible assemblies. We bring those up to current fire-interface compliance during the project, not after inspection flags it.
Pricing for General Contractor in Riverside, CA
Riverside pricing tracks the city’s dual code burden and its inland climate. Here’s what we’re currently seeing across the market:
| Project Type | Typical Riverside Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
The big variables are your home’s foundation type, its location relative to the WUI boundary, and whether the project triggers a seismic retrofit. A raised-foundation Craftsman in 92506 will cost more than a slab-on-grade 1990s build in 92507 for the same square footage because the scope includes bolting and bracing the older house doesn’t have. Call (855) 901-7266 and we’ll give you a written, line-item quote. Estimates are always free.

FAQs About General Contractor in Riverside
Because Riverside homes must satisfy two compliance burdens that coastal jobs typically don’t: seismic shear requirements on older raised-foundation builds, and WUI fire-resistant assembly rules in foothill-adjacent ZIPs. Add in the 100°F+ thermal cycling that demands heat-rated sealants, Class A roofing, and stainless or hot-dip hardware, and the material spec alone runs 15 – 25% higher than the inland-cheap version. The cheap spec fails within a decade in Riverside; the coastal-spec version never would have passed inspection here in the first place. Call (855) 901-7266 for an exact number on your roof or windows.
Yes, any structural, electrical, plumbing, or window replacement work in Riverside requires a permit through the city’s building department. We handle the entire permit process: drawings, submittals, plan check corrections, and scheduling the inspections. If your project triggers a seismic retrofit or WUI review, we manage that documentation too, so you’re not stuck at the counter explaining cripple-wall bracing to a plan checker. Call (855) 901-7266 and we’ll tell you exactly which permits your project needs.
The downtown Craftsman sits on a raised foundation that usually needs seismic bolting and cripple-wall bracing before any finish work starts, and the trim, window proportions, and wall assemblies are era-specific. The east-side tract home is slab-on-grade with modern framing but often has builder-grade exterior materials that have degraded under Riverside’s heat. We price and sequence the two jobs completely differently because the scope is different, not because one is “nicer” than the other. Call (855) 901-7266 and we’ll walk your specific home’s history.
We write every allowance as a specific dollar amount tied to a specific material, not a vague “TBD” line. You’ll see the exact fixture, cabinet line, countertop material, and roofing assembly in the contract before we start. If you upgrade from a Silestone allowance to a Cambria slab, we tell you the delta before you commit. Change orders in writing, signed by you, with the price in the line item. If the budget moves, you’ll know exactly why and by how much. Call (855) 901-7266 to see a sample estimate format.
Yes. We build ADUs and additions to current Riverside seismic shear requirements and, where applicable, WUI fire-resistant assembly standards for foothill-adjacent lots. That means engineered shear walls, ember-resistant vents, non-combustible or ignition-resistant siding, and Class A roofing where the plot falls inside the fire-interface boundary. We’ve built units on 92503 parcels that required every one of those details, and the inspections came back clean. Call (855) 901-7266 to discuss your ADU or addition scope.
On a 1920s Craftsman rehab in the 92501 core near downtown, our crew found the raised-foundation cripple walls unbolted and the original wood-framed windows fogged and rotting. We pulled permits, added seismic bolting and shear bracing, and set impact-rated vinyl units with stainless hardware so the punch list came back clean at inspection sign-off. For the roof we specified a Class A ember-resistant assembly with hot-dip galvanized fasteners rated for the heat cycling, not the builder-grade galvanized the prior roofer used.
