ADU Company in Mentone, CA
Kitchen remodeling in Mentone usually means working inside a home built between the 1950s and 1980s, where the original layout was designed for a different era. We regularly open up walls in Mentone kitchens and find aged wiring, undersized circuits, and slabs that have shifted over decades of inland heat and winter cold. That’s what makes this work different here: the remodel has to fix what’s behind the drywall before the finishes go in. If you’re planning a kitchen remodel or a full ADU project in Mentone, give us a call at (855) 949-1913 and we’ll walk you through what your specific home will need.
Why Mentone Homes Are Different
Mentone sits in San Bernardino County’s unincorporated county island east of Redlands, which means ADU and kitchen remodel projects answer to San Bernardino County’s ordinance rather than a city planning desk. That changes timelines, permit review, and what gets flagged during inspection. The housing stock here reflects the area’s history: single-family homes on generous lots, many with detached garages, workshops, and outbuildings that were never meant to be living space. When we work in Mentone, we’re often looking at converting those structures or remodeling kitchens in homes where the original electrical panel hasn’t been touched since the Carter administration.
The climate is the other factor. Mentone sits at the base of the San Bernardino Mountains in a hot-summer, semi-arid inland climate. Summer temperatures push cooling systems hard, and Santa Ana winds can arrive with real force in the fall. That means any kitchen remodel or ADU conversion here has to account for proper insulation, ventilation, and Title 24 shading requirements. We’ve seen too many garage conversions in Mentone where the previous owner skipped the envelope work, and the space is unusable from June through September.
There’s also the water and septic question. Because much of Mentone is unincorporated county land, the first thing we check on any ADU or major remodel isn’t design. It’s whether the lot has county water or a well, and whether the septic system has capacity for the added load. Many Mentone parcels are on older septic tanks sized for a three-bedroom house from 1965. Adding a second unit or a heavier-use kitchen changes that math, and it’s better to know before you start.
Our Main Mentone Services
Mentone homeowners call us most often for two projects: full ADU construction and bathroom remodeling connected to those units or to older primary homes. Here’s what each one involves in this area.
ADU Builders in Mentone
Building an ADU in Mentone usually means one of two paths: converting an existing detached garage or outbuilding, or building new on a large lot where the setbacks allow it. The conversion route is common here because so many Mentone properties have older garages and workshops that aren’t serving their original purpose. Those conversions run into the same issues as the main house: aged wiring, slabs poured without permits, and framing that was never designed for conditioned living space. We handle the full project under one contract, from the structure to the kitchen and bathroom inside, so you’re not coordinating a framer and then waiting on a separate finish contractor. Learn more on our ADU Builders in Mentone page.
Bathroom Remodeling in Mentone
Bathroom remodeling in Mentone often happens alongside an ADU build, but plenty of homeowners call us for the primary house too. The older homes here have small bathrooms with layouts that don’t work for modern use, and the plumbing underneath is frequently original galvanized pipe. When we remodel a Mentone bathroom, we’re usually replacing the rough plumbing, upgrading the venting, and bringing the waterproofing up to current code before tile goes down. If the bathroom is part of an ADU, we scope it as rental-ready from the start: durable finishes, proper ventilation, and a layout that works for a tenant. Details are on our Bathroom Remodeling in Mentone page.

Kitchen Remodeling in Mentone
Kitchen remodeling in Mentone means dealing with the bones of an older home first. Most kitchens here were built between the 1950s and 1980s, and the original layouts reflect that: closed off from the living space, minimal counter area, and electrical systems that predate modern appliance loads. The inland heat matters too. A Mentone kitchen with poor ventilation becomes unbearable in summer, so we plan range hoods, window placement, and insulation as core parts of the design rather than afterthoughts. Sunstone ADU Builders handles the entire remodel, including the kitchen finishes, so the project stays under one roof from demolition to final walkthrough. For a wider look at how we approach kitchens, see our Kitchen Remodeling page.
Full Gut Renovation
Signs you need it
Your Mentone kitchen has original 1960s cabinets, the floor slopes where the slab has settled, and the electrical panel can’t handle a modern range, microwave, and dishwasher at once.
What it costs in Mentone
A full gut renovation with layout changes, new electrical, and mid-range finishes typically runs $45,000 – $70,000 in Mentone depending on what’s behind the walls.
How we do it
We demo to the studs, replace the rough plumbing and electrical, level or repair the slab where it’s needed, reframe for the new layout, then install insulation, drywall, flooring, cabinets, counters, and appliances in sequence.
Layout Reconfiguration
Signs you need it
The kitchen is closed off from the dining area, the work triangle doesn’t function, and you’re cooking in a narrow galley while the rest of the house sits unused.
What it costs in Mentone
Removing or relocating interior walls and reconfiguring the kitchen layout runs $35,000 – $55,000 in Mentone when structural work is limited to non-load-bearing partitions.
How we do it
We confirm which walls are load-bearing, design the new sightlines and work triangle, move plumbing and electrical to match, patch flooring, and install the new cabinetry and counters in the reconfigured space.
What Kitchen Remodeling Costs in Mentone
| Item | Typical range in Mentone |
|---|---|
| Full gut renovation | $45,000 – $70,000 |
| Layout reconfiguration | $35,000 – $55,000 |
| Cabinet replacement only | $15,000 – $25,000 |
Costs in Mentone shift based on what we find when the walls open: knob-and-tube wiring replacement, slab leveling, or septic-related plumbing changes all add scope. We give you a written line-item quote before work starts, and that number doesn’t change unless you change the plan.
How long does a kitchen remodel take in Mentone?
Most full Mentone kitchen remodels run 6 to 10 weeks from demo to final inspection. The county permit review adds 2 to 4 weeks on the front end for San Bernardino County, and older homes with unpermitted prior work can add time when corrections are required. Call (855) 949-1913 for a schedule specific to your project.
Will my Mentone kitchen remodel trigger a septic or water review?
Not usually for a kitchen-only remodel, but adding a dishwasher, pot filler, or second sink changes your water fixture count, and San Bernardino County may review it. If the remodel is part of an ADU project, the septic and water capacity question comes first. We check this before design starts.
Brands We Service in Mentone
We install and service kitchens built around Boxabl and Plant Prefab units, plus Tuff Shed-style structures converted to conditioned living space. For exteriors, we specify James Hardie fiber cement siding on most Mentone projects because it handles the summer heat and Santa Ana wind exposure better than vinyl. See our brands for the full picture.
