Fast, Reliable General Contractor Across Riverside
Riverside homeowners calling a General Contractor usually have one question: what will this actually cost once the walls are open? The honest answer is that a kitchen remodel here runs $14,000 – $45,000 and a bathroom runs $9,000 – $28,000, but those ranges only hold if your contractor knows what’s behind Riverside’s plaster and stucco. Alder Contractors, led by Nelson Ibarra, works the Wood Streets, downtown core, and the 92508 tract homes east of the 91 the same way: we inspect before we quote, write allowances into the contract, and put every discovery on paper before we touch a joist. Call (833) 467-7020 for a free estimate that accounts for what your house actually is, not what a generic bid sheet assumes.
Why Alder Contractors Is Riverside’s Preferred General Contractor Company
We’ve spent enough time in Riverside’s older neighborhoods to recognize a painted-over redwood siding job on an Elmwood Drive Craftsman, and enough time in 92508 to know what a post-tension slab means for a bathroom rough-in. That split is the whole job here. A contractor who only builds new tract homes will underprice a Wood Streets gut renovation, and one who only does historic work will overcomplicate a 1990s stucco tear-out. Alder sits on both sides. Our crews run from the Jurupa Hills to the Box Springs corridor weekly, and we know which permits will drag and which will clear fast before we ever file them.
As an Riverside homeowner, you’re not hiring a brand. You’re hiring Nelson Ibarra and a crew that has signed change orders for knob-and-tube replacement in century-old kitchens and pulled permits for slab work in newer subdivisions. We handle whole-home scopes, from a full kitchen gut in a 1920s bungalow to a hardscape and fencing package on a 2000s lot in 92508. One contract covers it.
Styles & brands we work with







Residential General Contractor in Riverside
Residential General Contractor work in Riverside means something different block by block. In the Wood Streets and downtown, it means opening walls and finding wiring and plumbing your home’s last remodel never touched. East of the 91, it means precise work on post-tension slabs where drilling through a tension cable turns a $9,000 bathroom into a structural repair. Alder plans for both. We walk the house first, check the foundation type, look at the panel, and note any historic-context triggers before we put a number in front of you. That’s the difference between a quote that holds and one that doubles at rough-in.
Older Home Renovation
Pre-1950 Riverside homes sit on raised pier-and-beam foundations with original clay sewer laterals and, far too often, knob-and-tube wiring still live in the walls. We write inspection findings into the allowance schedule so the electrician’s and plumber’s fixes are priced as options, not surprises. A full kitchen remodel in this housing stock runs $14,000 – $45,000 depending on what we find and what you select.
Newer Tract Home Remodel
In 92508 and similar 1980s – 2000s subdivisions, slab-on-grade construction changes how we move drain lines and where we can add a kitchen island. A bathroom remodel here typically runs $9,000 – $28,000. We map utility locations against slab plans before any cutting starts, because a tension cable strike is an expensive lesson we’ve never once wanted to repeat.
Hire a General Contractor in Riverside
Hire a General Contractor in Riverside who understands that this city’s building stock is two different jobs wearing one zip code. A home addition in the Wood Streets triggers a historic-context review that adds weeks to the permit, while the same addition in a newer tract clears quickly. Alder files for both, prices both, and schedules around both. Nelson Ibarra’s crews know the planning desk’s triggers here: any addition touching a pre-1950 structure goes into review, so we don’t frame an addition as a remodel to save time and stall you mid-rough-in.
Additions and ADUs
A home addition in Riverside runs $45,000 – $130,000, and an ADU runs $90,000 – $220,000 depending on foundation type and historic review scope. Alder is also a prefab ADU partner for Abodu, Dvele, Mighty Buildings, and Boxabl, which gives you a path to added space that bypasses some of the on-site construction time, though not the permit review.
Whole-Home Scope, One Contract
If you’re doing a kitchen, a bath, a roof, and a paver driveway, one contractor should own the schedule. We run interior remodeling, exterior replacements, and hardscape under one agreement with one draw schedule. You’re not juggling four vendors and four excuses.

AfterCommon General Contractor Problems We See in Riverside Homes
- Knob-and-tube and galvanized steel in the old core. Wood Streets and downtown bungalows routinely have original wiring and supply lines still live inside walls, and any remodel that touches those walls triggers a code upgrade. We price the electrician’s and plumber’s work into the allowance before you sign.
- Post-tension slab drilling in newer tracts. Homes in 92508 and similar subdivisions sit on tensioned concrete, and a bathroom rough-in that doesn’t map cable locations can turn a simple drain move into structural repair. We map first, cut second.
- Historic-context review triggers on small additions. In pre-1950 neighborhoods, even a modest bump-out is reviewed, and a contractor who skips the filing stalls your project mid-rough-in. We file correctly from day one.
- Painted-over original siding and failed waterproofing. Riverside’s older homes hide redwood or cedar siding under a dozen paint layers, and once we open an exterior wall, rot and moisture intrusion around the drainage plane are common. We replace what’s failed and document every discovery in writing.

FAQs About General Contractor in Riverside
Because pre-1950 Riverside homes frequently hold knob-and-tube wiring, galvanized steel supply lines, and original clay sewer laterals that no permit inspector will allow to remain exposed once you open the wall. We price those as written allowances before the demo starts, so the increase is a signed contract line, not a verbal surprise.
A kitchen or bath remodel inside the existing footprint generally does not trigger historic-context review in downtown Riverside. An addition or any change to the exterior envelope of a pre-1950 structure does, and we file accordingly so the permit doesn’t stall mid-project. Call (833) 467-7020 if you’re unsure which category your scope falls into.
We map the slab’s cable layout against the architectural plan before cutting any concrete for drain lines or floor outlets. A post-tension cable strike is a structural repair with a five-figure tail, so we don’t guess at cable locations, and neither should any contractor working your home.
It means every anticipated discovery, from knob-and-tube replacement to rotted framing, is priced as a written line item with a specific dollar allowance before you sign the contract. If the job comes in under the allowance, you pay less. If it comes in over, we get your signature on a change order before spending another dollar.
Yes, every Alder Contractors project in Riverside runs on a written draw schedule tied to completed work that passes the city’s inspection checkpoints. You release funds as the inspector signs off on rough-in, waterproofing, and final, not on a calendar date with nothing to show for it. Call (833) 467-7020 to see a sample schedule for your project type.
