Why San Jose Homeowners Choose Lodgewick ADU San Jose for ADU
Russ Delmar leads our San Jose branch, and the reason homeowners keep calling us is simple: we say the price before the work starts, and we put the warranty in writing. Building an ADU is a significant investment, often between $250,000 and $450,000 here in Santa Clara County, so you deserve a builder who doesn’t make you guess. Our clients across San Jose, from Willow Glen to Almaden Valley, tell us the same thing: the written quote matched the final invoice, and the crew showed up when they said they would.
6 Reasons We’re San Jose’s Top ADU Company

Local Experience That Shows in Every Job
We’ve built ADUs throughout San Jose and the surrounding cities long enough to know the quirks of each neighborhood’s permitting process. In the East Foothills, hillside setback rules change how we site a detached unit. In Alum Rock, older lot lines sometimes require a survey before we can break ground. That kind of local knowledge isn’t something you learn from a website. It comes from walking the lots and sitting in the planning office.
A Reputation Built on Showing Up
Our clients in San Jose, Fremont, and Los Gatos give us strong reviews, and we earn them by keeping our word. When we give you a window for when our team will arrive, we show up inside it. That’s the Kingswell Way, and it applies to every visit, from the first site walk to the final inspection. Homeowners who’ve been burned by no-shows tell us it’s the main reason they chose us.
Licensed, Insured, and Held to a Standard
Every pro who works under the Lodgewick ADU San Jose name is required to hold the license and insurance that California requires. That’s not a perk, it’s a baseline. We don’t ask you to take our word for it either. We’ll show you our credentials before any work begins, and we’re glad to walk you through what each document means for your project.
Real Expertise with the Brands You’re Researching
If you’ve been comparing prefab and modular ADU options, you’ve likely come across Abodu, Cover, and Dvele. We work with these systems regularly and know how they perform in San Jose’s specific conditions. That means we can tell you honestly how a panelized Abodu unit handles our rainy winters, or whether a steel-framed Cover unit makes sense on your particular lot. We’re not married to one manufacturer. We recommend what fits your property and your budget.
Transparent Pricing, Written Down
Before any work starts, you get a written price. Not a verbal estimate, not a range that might creep upward. A line-item quote you can hold us to. We’ve built a strong local reputation in San Jose by refusing to play the change-order game. If something comes up during construction, we discuss it with you before spending a dollar. You’ll never open an invoice and wonder where a number came from.
The Kingswell Guarantee in Writing
Lodgewick ADU Builders is the ADU company of the Kingswell family, and every location works to the same four promises: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. That promise is stamped on every contract. It’s not a marketing line, it’s how we operate.
