Why Lodgewick ADU Sacramento Is Folsom’s Preferred ADU Builders Company
Homeowners across Folsom call us because we put the price in writing before a single nail is driven. That matters here more than most places, because Folsom’s layered approval process means you’ll see enough paperwork without adding surprise change orders on top of it. Russ Delmar and our team have worked on ADU projects off Blue Ravine Road, East Bidwell Street, and Iron Point Road, and we know which plans move through the city’s design review faster. Russ built his reputation the hard way: he answers the phone, he honors the arrival window, and he comes back if anything isn’t right. The 365-Day Done Right Promise backs that up in writing on every job.
Lodgewick ADU Builders is part of the Kingswell family of home-service companies, founded in 2010. A lodge is a small house on a larger property, which is exactly what an ADU is. We’ve kept that simple idea at the center of our work in Folsom while most other contractors have been chasing bigger margins on bigger homes. Our Folsom customers tell us the same thing: they’d been burned by contractors who gave a low number over the phone, then changed it at the door. We don’t do that. Ever.
Detached ADU in Folsom
A Detached ADU in Folsom is a fully separate living unit built in the rear yard of your existing home, and on Folsom lots that average 6,000 to 8,000 square feet, there’s often room for one without touching your current structure. We handle detached ADU construction throughout Folsom, including the ranch-home neighborhoods near Lake Natoma where a standalone unit often means less disruption to the original 1950s and 60s home than an attached addition would.
What a Detached ADU Costs in Folsom
Plan on $180,000 to $450,000 for a detached unit, depending on square footage and finish level. A studio around 400 square feet with a kitchenette starts near the lower end, while a two-bedroom unit with full kitchen and its own laundry pushes toward the top of that range. We include the written price before work starts and we hold it, no exceptions.
Site Work and Utilities on Folsom Lots
Many Folsom lots have concrete patios or hardscape already in place where a detached ADU would go. We handle the demo, trenching for new utility lines, and the connection to your main panel. If your existing panel is at capacity, we’ll include that upgrade in the written estimate up front, not as a surprise later.
JADU in Folsom
A JADU (Junior Accessory Dwelling Unit) in Folsom is a converted space within your existing home, usually a bedroom or attached garage area that becomes a smaller studio with its own entrance and a kitchenette. JADUs work well in Folsom’s older 1950s and 60s ranch homes, which often have an attached garage or a large bedroom that’s better suited for conversion than for adding new square footage.
What a JADU Costs in Folsom
JADU projects in Folsom typically run $80,000 to $150,000. That’s a fraction of what a detached ADU costs because there’s no new foundation, no new roof, and no separate utility trenches. You’re converting space you already have, which also keeps the permitting path shorter.
Why Folsom Homeowners Choose a JADU
Most people we talk to in Folsom want a JADU for an aging parent or an adult child who needs a place to land. The mortgage rates of the last five years changed the math for a lot of families here. A JADU gives you a separate entrance and a small kitchen without the full cost of a new detached building, and in Folsom’s HOA-heavy neighborhoods, a JADU inside the existing footprint often faces fewer approval hurdles.
Trusted Brands We Service in Folsom
We work with Abodu, Cover, and Dvele prefab systems, and we install James Hardie siding on many Folsom Abodu service projects. Prefab units from Abodu and Cover arrive in modules and go up faster than stick-built, which matters here because Folsom’s summer heat can slow traditional framing. We keep local relationships with inspectors and material suppliers in the Folsom area, so a missing bracket or a short siding run doesn’t mean a two-week delay. Call (279) 256-1973 and we’ll walk you through which system fits your lot and budget.
Common ADU Builders Problems We See in Folsom Homes
- HOA design reviews stalling the project. Folsom’s master-planned communities, especially Empress Ranch, Stonebriar, and Lexington Hills, have committees that review ADU designs before the city does. We’ve found that submitting craftsman-style plans with covered entries and colors that echo the main house gets through faster.
- Summer heat wrecking framing schedules. Folsom regularly hits over 100°F from June through September. That heat warps exposed lumber and pushes workers to shorter morning shifts. We schedule framing for the coolest part of the day and spec materials that hold up in direct Sacramento Valley sun.
- Older ranch homes with undersized panels. Homes near the historic district and along Hinkle Creek often have 100-amp panels. Adding an ADU usually means upgrading to 200 amps, and we write that into the estimate from the start.
- Riparian setback surprises near Lake Natoma. Properties close to Lake Natoma or the American River can trigger extra review for floodplain and setback rules. We check those parcels early in the process so a homeowner doesn’t pay for plans that can’t be approved.
