Local Notes

Perris follows the California state ADU baseline. The city's older neighborhoods near downtown have generous lots but aging utilities — we verify panel capacity and sewer condition during the feasibility walk. Newer subdivisions like May Ranch and Villages of Avalon have modern infrastructure that keeps ADU buildout predictable.

Why Perris

Why build an ADU in Perris.

Perris offers some of the best ADU economics in Riverside County: land is affordable, lots are generous, and rental demand keeps climbing with the city's growth. The March Air Reserve Base employment corridor, the massive logistics parks along I-215, Lake Perris recreation traffic, and the Metrolink 91/Perris Valley Line all feed a steady tenant pool for one- and two-bedroom units. Because Perris home prices are lower than the regional median, ADU appraisal lift as a percentage of property value is often higher here than anywhere in the county — and rental income covers a larger share of construction cost. For owners of older downtown properties, an ADU project is also the natural moment to modernize aging utilities and compound the whole parcel's value.

Beyond the ADU

Full-service remodeling in Perris.

The ADU rules above are only part of what we build in Perris. The same crew handles kitchens, bathrooms, room additions, and windows — permitted through the same building department.

Perris spans more housing eras than almost any city in Riverside County. Historic bungalows and mid-century homes surround the old downtown along D Street — home of the Southern California Railway Museum — while master-planned subdivisions like May Ranch, Villages of Avalon, and Green Valley have added thousands of newer homes on the city's edges. Lake Perris, Skydive Perris, the Perris Auto Speedway, and the Metrolink 91/Perris Valley Line round out one of the county's fastest-growing communities.

That range means remodeling needs run the full spectrum, and we work both ends of it weekly: repiping and re-wiring older downtown homes while their kitchens and bathrooms are rebuilt, and taking builder-grade 2015-plus tract homes to custom with new cabinetry, quartz, and whole-home LVP. Perris's strong price-to-value market means quality renovation moves the appraisal needle further here than in most of the region.

We're about 40 minutes from Perris via the 60 and I-215 from our Yucaipa headquarters, pulling permits through the City of Perris Building and Safety Division. One in-house crew, one fixed-price contract, one warranty.

Kitchen Remodeling
→
A permit is triggered the moment plumbing, gas, or electrical circuits move — which covers most full kitchen remodels. We draw the plans, run plan check, and build the permit fees into your fixed price.
Bathroom Remodeling
→
Tub-to-shower conversions, drain relocations, and new exhaust ventilation all require permits and inspections. We handle the submittal and every inspection through final sign-off.
Room Additions
→
Additions get full structural plan review — foundation design, framing calcs, and Title 24 energy compliance. Our engineering is stamped before we bid final numbers, so plan check doesn't stall the schedule.
Windows & Doors
→
Retrofit windows need a permit and Title 24 U-factor compliance in every California city. We pull the permit, install to manufacturer spec, and schedule the final inspection.

In Perris, residential permits run through the same counter we work for ADU plan checks — Perris Building and Safety Division.

Perris Remodeling FAQ
Does Construction Station serve Perris?
Yes — Perris is well inside our core Inland Empire service area, about 40 minutes southwest of our Yucaipa headquarters via the 60 and I-215. We're in the Perris Valley regularly, and every project starts with a free in-home consultation.
What remodeling services do you offer in Perris?
Kitchen remodeling, bathroom remodeling, flooring installation, room additions, ADUs and garage conversions, windows and doors, and full general-contracting work. In Perris that ranges from modernizing 1950s downtown bungalows to upgrading brand-new tract homes in May Ranch and Villages of Avalon.
How much does a remodel cost in Perris?
Typical ranges: kitchens $45,000–$95,000, bathrooms $20,000–$45,000, flooring $6–$9 per sq ft installed for quality LVP, room additions $350–$550 per sq ft, ADUs $250–$550 per sq ft. Perris's affordability means these projects often return more at appraisal, proportionally, than the same work elsewhere in the region.
Can you handle older Perris homes with outdated plumbing or electrical?
Yes — it's a specialty. Many pre-1980 homes near downtown Perris still carry galvanized supply lines or 100-amp panels. We fold repipes and panel upgrades into kitchen and bathroom remodels while the walls are already open, which costs a fraction of doing that work standalone later.
Is it cheaper to add on than to move in Perris?
Usually, by a wide margin. Between selling costs and today's mortgage rates, trading up from a home you bought years ago is expensive — while a room addition adds the space and appraised value without touching your existing loan. We'll give you a fixed addition price at the free consultation so you can compare with real numbers.
Are you licensed and insured for work in Perris?
Yes — Construction Station is a licensed California general contractor (CSLB #1108879), bonded and fully insured, with an A+ BBB rating, family-run since 2008. Verify the license anytime at cslb.ca.gov.

Perris FAQ

Perris ADU questions, answered.

How much does an ADU cost in Perris?
Perris ADUs typically run $250–$400 per sq ft for garage conversions, $300–$450 per sq ft for attached room-addition ADUs, and $350–$550 per sq ft for new detached ADUs. A 400 sq ft garage conversion typically lands between $100,000 and $160,000; a 1,200 sq ft detached ADU between $420,000 and $660,000 depending on finish level and site conditions. Your free Perris feasibility consultation ends with a transparent line-item estimate.
How long does it take to get an ADU permit in Perris?
California state law caps ADU plan-check review at 60 days, and Perris processes ADU permits within that window. Total time from signed contract to permit-in-hand typically runs 8–14 weeks, including design, structural engineering, Title 24 energy compliance, and any plan-check corrections. Construction begins immediately after the permit is issued.
Can I rent my ADU in Perris?
Yes — long-term rentals of 30 days or more are allowed statewide in California, and that applies in Perris. Short-term rentals under 30 days are governed by local ordinance and vary by city. We confirm any Perris-specific short-term rental restrictions during your free consultation so there are no surprises.
Do I need owner-occupancy for an ADU in Perris?
No — California permanently removed the owner-occupancy requirement for standard ADUs as of 2026, so you can build and rent an ADU in Perris whether or not you live on the property. The one exception is a JADU (Junior ADU): if you build a JADU, owner-occupancy of either the primary home or the JADU is required.
Does Construction Station build ADUs in Perris?
Yes. Construction Station is a licensed California general contractor (License #1108879) and has been building ADUs across the Inland Empire, Temecula Valley, Desert, and Orange County–adjacent communities since 2008. We handle the entire Perris project — feasibility, design, structural engineering, permits, construction, and final inspection — under one fixed-price contract and one warranty.
