Adding an ADU in Carmichael usually means working with a 1950s-1970s ranch home on a quarter-acre lot, an aging 100-amp electrical panel, and Sacramento County’s impact fees that can climb past $20,000. We’re Lodgewick ADU Builders, the ADU company of the Kingswell family, and we handle accessory dwelling units, garage conversions, and home additions across Carmichael under The Kingswell Guarantee: a written price before work starts, a real arrival window, a clean job site, and a written guarantee on every project.

Why Carmichael Homes Are Different
Carmichael’s housing stock leans heavily toward single-story ranch homes built between the 1950s and 1970s, most on lots of a quarter acre or more with wood-frame construction and slab foundations. That’s good news for homeowners who want a detached ADU – there’s usually room in the side or rear yard without squeezing the main house. But those same older homes often have a problem hiding in the garage or on the exterior wall: a 100-amp electrical panel. Adding an ADU almost always means upgrading to 200 amps, and local electricians regularly tell us that’s the first and most expensive step in a Carmichael project.
The climate shapes the work too. Summers push past 95°F for stretches, so a poorly insulated ADU becomes an oven by July. Winters bring mild but sometimes heavy rain, and roof tie-ins between the main house and the new unit have to be flashed and sealed correctly the first time. We size HVAC and insulation for Carmichael’s dry heat specifically, not a generic California average.
Then there’s the big one: Sacramento County impact fees. Depending on square footage and a few other factors, fees for an ADU in Carmichael can reach $20,000 or more before a single board is purchased. That changes the math on every project, and it’s why we talk about cost-saving design options early – a slightly smaller footprint, a more efficient layout, or a prefab system can pull thousands out of the total. Homeowners adding units for multi-generational living, a common pattern here, feel that fee pain more sharply than anyone.
Our Main Carmichael Services
These are the three services Carmichael homeowners call us about most often. Each has its own dedicated Carmichael page with specific pricing, timelines, and local details for that type of work.
Home Addition Contractor in Carmichael
A home addition in Carmichael often works with the same lot advantages as an ADU – space is rarely the problem. The challenge lies in tying a new structure into a 50-to-70-year-old ranch home without disturbing the existing footprint, and in bringing an old electrical system up to the load a new wing requires. We plan for panel upgrades, roof transitions, and Sacramento County’s permitting process from day one, so the addition doesn’t turn into a series of surprises. Home Addition Contractor in Carmichael
Garage Conversion Contractor in Carmichael
Carmichael’s ranch homes often have attached garages that were built for a single car and now hold everything except one. A garage conversion turns that square footage into livable space without changing the home’s footprint, which matters a lot here because setback rules and lot coverage limits can cap how much you’re allowed to add outward. Electrical upgrades are the recurring theme – the existing garage circuit was never meant to carry a kitchen or a bedroom. Garage Conversion Contractor in Carmichael
ADU Builders in Carmichael
Carmichael’s RD-5 zoning allows attached or detached ADUs, and the large lots make detached units especially practical for families bringing in parents or adult children. We’ve built and installed ADUs across Carmichael using stick-built construction and prefab systems where the lot and budget make sense. The two constants are Sacramento County fees and the 100-to-200-amp panel upgrade, which we factor into the written price before work starts rather than treating it as a mid-project discovery.
