Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions in Santa Fe, TX, and we do it differently than most crews you’ve met: a written price before any work starts, a real arrival window, and a written guarantee on every project. Santa Fe lots tend to be larger than what you find closer to Houston, which sounds great until you realize the extra space comes with drainage questions, older slab conditions, and HOA quirks that change how an ADU should be designed. That’s where local know-how actually matters. Call (361) 326-2313 if you’re weighing a detached unit, a garage conversion, or an attached addition.
Why Santa Fe Homes Are Different

Santa Fe sits on flat, coastal-plain ground where expansive clay soil is a real factor. That soil swells when wet and shrinks when dry, and a foundation that hasn’t been checked before adding square footage can turn a $40,000 ADU into a much bigger headache. Homes here lean heavily toward ranch-style builds from the 1970s through the 1990s, many on half-acre lots along FM 1764 and State Highway 6. Older slabs are usually fine, but we check them before we design anything, because the cost to correct a slab issue that a past owner ignored is often the single biggest surprise on a Santa Fe addition budget.
Another Santa Fe reality: a lot of properties are outside city sewer lines and run on septic systems. Adding a bathroom or a kitchen to a detached ADU means understanding whether the existing septic field has capacity, and some HOA communities have covenants that restrict detached structures entirely. We’ve worked enough in Santa Fe to know which questions to ask first, and it saves homeowners weeks of back-and-forth.
Our Main Santa Fe Services
Most Santa Fe homeowners call us for one of two reasons: they’ve outgrown their current home, or they have a garage that isn’t pulling its weight. Here’s how each works here.
Home Addition Contractor in Santa Fe
A home addition in Santa Fe usually means extending the slab, matching rooflines, and tying new framing into a house built decades ago. The challenge isn’t just square footage; it’s making the new section look like it was always there. We account for clay soil movement, existing septic capacity, and what the HOA will actually approve before we draw the first plan. If you’re adding a primary suite, a second living area, or a larger kitchen, the process starts with a site visit your free estimate covers. Read more about how we approach additions on our Home Addition Contractor in Santa Fe page.

Garage Conversion Contractor in Santa Fe
Converting a garage in Santa Fe is one of the fastest ways to add a rentable or livable unit because the structure, slab, and roof already exist. What most people don’t plan for is insulation: Santa Fe summers are brutal, and a garage that was never meant to be lived in will bake anyone inside unless the walls and ceiling are properly insulated and sealed. We also handle the mechanical work, from split HVAC systems to electrical panel capacity, so the converted space passes inspection the first time. See the full scope on our Garage Conversion Contractor in Santa Fe page.

ADU Builders in Santa Fe
Building a detached ADU in Santa Fe means addressing three things most generic builders skip: septic capacity, drainage, and distance from the main home’s utilities. A lodge is a small house on a larger property, which is exactly what an ADU is, and the stock here supports that idea well. We work with prefab manufacturers and traditional stick framing depending on your lot and budget, and every plan includes the written price before a single nail is driven. Learn more on our ADU Builders in Santa Fe page.
