ADU Company in Perris, CA

Kitchen remodeling in Perris means working with homes built mostly in the 1980s through 2000s, where closed-off galley layouts meet a desert climate that demands serious ventilation and surfaces that won’t warp in dry heat. We’re Westminster ADU Builders, and while ADUs are our core business, the kitchens inside them – and the kitchens in the main homes we’re already touching – are a natural extension of the work we do across Perris. If you’re planning a detached ADU with a full kitchen, or your existing tract home’s kitchen needs a real update, call (833) 620-3521 for a free estimate.

Why Perris Homes Are Different

Perris sits in a hot, dry inland valley where summer temperatures routinely top 100°F, and that single fact changes how we approach nearly every project. Ventilation isn’t optional here. Range hoods need to move real air. Refrigerators work harder. Flooring choices that look great in coastal California will bake and fade within a few seasons in Perris. We specify materials for this climate – reflective roofing, deep overhangs, and tight weather-sealing that keeps dust and wind-driven grit out of a stick-built addition.

The housing stock compounds that. Most of Perris is 1980s-2000s production tract homes on lots between 7,000 and 10,000 square feet. Those homes were built fast, often with builder-grade cabinets, laminate counters that have long since delaminated, and service panels that were never meant to carry a second dwelling. Around the 92570 core you’ll find older 1950s-70s ranch homes, many still on septic. Each era has its own quirks: the tract homes have awkward lot lines and rear-alley easements; the older parcels have septic-to-sewer questions that need answers before anyone pours a foundation. And a lot of Perris backyards still have the original builder’s slope with no drainage, which means the first real job on many projects is grading and a drainage plan – not the structure. Inspectors here will flag drainage before they’ll even look at framing.

Our Main Perris Services

Two services dominate the calls we get from Perris homeowners: detached ADUs and bathroom remodels – often both, since an ADU needs a bathroom and the main house usually needs one updated too.

ADU Builders in Perris

Detached backyard ADUs are the dominant play in Perris. The lots are big enough to make them work, and the city sits in a state-designated low-income/high-unemployment tract zone where California’s ADU fee waivers and reduced parking requirements hit hardest. That means the money conversation is often about pre-approved plans and waived fees rather than custom design. We build both prefab and site-built ADUs here, which matters because your lot’s grading, access, and easements might push you one direction or the other. ADU Builders in Perris gives you the full picture.

Bathroom Remodeling in Perris

Bathroom remodeling in Perris usually means working around existing slab plumbing in tract homes, where moving a drain line can mean cutting concrete. The dry climate means moisture issues show up differently here – less mold risk than coastal areas, but hard water from Riverside County’s supply will wreck cheap fixtures fast. We handle full bathroom remodels for the main house and finish out bathrooms inside new ADUs with the same crew, so there’s no subcontractor handoff. Bathroom Remodeling in Perris covers the details.

Kitchen Remodeling in Perris

Most Perris kitchens were built in the 1980s through 2000s, which means galley layouts, soffits over the upper cabinets, fluorescent box lighting, and electrical that was barely adequate when it was new. In this climate, the real problem is ventilation and cooling: Perris summers push a cramped kitchen over 90°F by mid-afternoon, and a recirculating hood that never actually vents outside just makes it worse. Remodeling a Perris kitchen isn’t about cosmetics – it’s about knocking down a wall to open the floor plan, running a real exhaust duct to the exterior, and upgrading the service panel so the new double ovens and hood can actually run without tripping a breaker. That’s the work we do through our Kitchen Remodeling team.

Open-Concept Redesign

Signs you need it

You have a galley kitchen sealed off from the living space, and family members bump shoulders while cooking.

What it costs in Perris

Removing a non-load-bearing wall and opening the kitchen to the living room in Perris typically runs $4,000 to $8,000 including drywall patch, flooring transition, and paint – more if the wall is load-bearing.

How we do it

We assess which walls are carrying load, work up the beam or header plan if needed, pull the Perris permit, and frame, drywall, floor, and finish in sequence so your kitchen stays usable as long as possible.

Full Cabinet and Countertop Replacement

Signs you need it

Your cabinet faces are delaminating from years of dry heat, hinges are sagging, and the laminate counters are worn through at the edges.

What it costs in Perris

Cabinet replacement in Perris usually runs $12,000 to $25,000 for a typical 10×12 tract kitchen, while countertops run $2,000 to $5,000 depending on material – quartz holds up better than laminate in this climate.

How we do it

We demo the old boxes, verify the walls are square, set new cabinets level on the existing slab or subfloor, then template and install counters with proper overhangs and sealed seams.

What Kitchen Remodeling Costs in Perris

Item Typical range in Perris
Open-concept wall removal $4,000 – $8,000
Cabinet replacement (10×12 kitchen) $12,000 – $25,000
Countertop replacement $2,000 – $5,000

Yes. We finish ADU kitchens and remodel main-house kitchens with the same team and the same standards, so cabinet profiles, counters, and hardware can match across both spaces. Call for details.

No. We provide written line-item quotes and fixed pricing with no change orders, so the number you approve is the number you pay. Call (833) 620-3521 for an exact quote.

Brands We Service in Perris

We work with a defined roster of prefab ADU brands – Abodu, Cover, and Dvele among them – and use James Hardie fiber-cement products for exterior applications across Perris.

What pushes prices up in Perris? Access. A lot of backyards have single-track or unpaved access, which adds time and machinery costs for anything being delivered or dug. If your lot still has the original builder’s slope and no rear drainage, expect grading and drainage work to appear as a line item before any structure goes up. We give upfront written quotes with fixed pricing, so you’ll see every line item before you sign anything. Call (833) 620-3521 for a free estimate.
