Adding an accessory dwelling unit, a second smaller home on your existing lot, is one of the smartest ways to create space for aging parents, adult kids, or rental income here in Carmichael. Most detached ADUs in Carmichael run between $250,000 and $420,000, while garage conversions typically land between $120,000 and $200,000. The catch on our side of the county line is that a Carmichael address means Sacramento County rules, not city rules, and those rules can add five figures to your project before a shovel hits dirt. Our ADU Builders team knows exactly where the county fees, setbacks, and septic checks bite, and we scope for them before you pay for plans. Call us at (279) 256-1973 and we’ll walk your lot, check the county constraints, and put a real number in writing.
Why Lodgewick ADU Sacramento Is Carmichael’s Preferred ADU Builders Company
Carmichael homeowners call us because we do the unglamorous work first: we verify county zoning, septic and well setbacks, SMUD service capacity, and drainage before we quote a single design. That upfront legwork is what keeps a Carmichael ADU from turning into a variance hearing, an $18,000 surprise, or a slab that pools water every winter. The Kingswell family built this company in 2010, and Russ Delmar leads our Sacramento team with a simple operating promise called The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written 365-Day Done Right Promise on every project. If the work isn’t right, we come back and make it right. That’s in writing, on your project, before the first nail is driven.
We serve the whole Carmichael footprint, from the ranch homes along Walnut Avenue and the streets east of Ancil Hoffman Park, down through the Del Campo and La Sierra neighborhoods, and west toward Carmichael Park and Garfield Avenue. Homeowners in those areas have told us the same thing: other contractors quoted a pretty number, then the county changed it. We quote the county’s number up front. A live person answers our phones 24/7, which matters when you have a grading question on a Sunday or a permit deadline on a Tuesday.
ADU Contractor in Carmichael
An ADU Contractor in Carmichael is the general contractor who carries the whole build: site feasibility, county permits, foundation, framing, mechanicals, finishes, and the final inspection sign-off with Sacramento County. Carmichael homeowners need this role more than city dwellers do because the large RD-5 lots here come with county-specific complications: well setbacks, possible septic systems, aging 100-amp panels, and long driveways that complicate material delivery. A full detached ADU build in Carmichael, contractor-included, runs $275,000 to $420,000; a garage conversion with plumbing and a kitchenette runs $140,000 to $200,000. We absorb the county’s permitting sequence into our schedule, so you don’t have to become a part-time planner.
Site Feasibility Before Plans
On Carmichael acreage, the first hire should not be an architect. It should be someone who reads the county parcel map and walks the lot. We measure setbacks from your house, property lines, any well, any septic leach field, and any creek or drainage swale. If the well is 80 feet from where you want the ADU and the county wants 100, we know that before you spend $8,000 on drawings. That single check has saved Carmichael clients more than the cost of the entire permit package.
Permit Readiness and County Paperwork
Sacramento County building permits differ from city permits in timing, fee structure, and review queue. We prepare the site plan, structural drawings, Title 24 energy calcs, and SMUD service application as one package so the county reviewer doesn’t bounce it back three times. Each round-trip with the county can add weeks and re-review fees. We don’t charge you to resubmit paperwork we prepared.
ADU Design in Carmichael
ADU Design in Carmichael means working backward from the county’s rules, not forward from a Pinterest photo. We start with the setback math and the septic or sewer reality, then shape the unit to fit the usable portion of your lot. A well-designed Carmichael ADU also accounts for our climate: hot, dry summers that regularly pass 95°F and wet winters that test every roof tie-in. Design fees here typically run $12,000 to $25,000 depending on unit size and whether we’re using stock plans, a prefab manufacturer like Abodu or Cover, or a fully custom drawing set. We prefer to have our designer and our estimator in the same meeting, so the pretty concept and the real cost never drift apart.
Ranch-Lot Footprints That Work
Most Carmichael ADUs are 750 to 1,200 square feet, and the best ones sit toward the rear or southwest corner of a 0.25-acre or larger lot, away from the main house and away from the well. We favor simple gable or shed roofs that tie into the existing roofline cleanly and shed rain toward the lot’s natural drainage. Slab-on-grade works well on Carmichael’s flat ranch lots and avoids crawlspace moisture issues we see in older homes here.
Prefab and Panelized Options
For Carmichael clients who want speed and tighter cost control, we install prefab units from Abodu, Cover, and Dvele, and we match James Hardie siding to the main house so the ADU looks like it grew there. Prefab doesn’t skip the county steps, but it does compress on-site framing time and reduces the weather exposure we deal with during our wet winters. Delivery access matters: narrow driveways or low utility lines can turn a standard crane set into a more expensive two-piece assembly.
Trusted Brands We Service in Carmichael
We work hands-on with Abodu and Cover prefab systems, Dvele panelized builds, and James Hardie siding and trim because Carmichael’s older ranch homes deserve finishes that hold up to triple-digit summers without fading or warping. We keep local material runs short by sourcing through suppliers that serve Sacramento County, which helps when a Carmichael client needs a siding match for a 1962 ranch home or an extra panel of Hardie Board after a field measurement. If you already have a prefab unit spec’d or a favorite material in mind, we will tell you honestly whether it fits your lot before you commit to it.
Common ADU Builders Problems We See in Carmichael Homes
- Well and septic setback surprises. A Carmichael lot on a private well or septic system has county-mandated distances between those systems and any new structure. We have seen clients pay for architectural plans, then learn the ADU footprint sits 20 feet inside the 100-foot well setback. That redesign cost them money and months.
- The 100-amp panel problem. Most Carmichael homes built in the 1950s through 1970s still run a 100-amp electrical service. Adding an ADU with a mini-split, kitchen appliances, and a washer-dryer almost always pushes you to a 200-amp upgrade, and the service drop from SMUD can be undersized too. That’s a $5,000 to $9,000 line item people forget to quote.
- Sloped-lot drainage ignored. Carmichael is mostly flat, but not uniformly so. Lots near the American River Parkway or along the eastern edges have gentle grades that send winter rain where you don’t want it. We walk the lot after a rain, when possible, and look for standing water before setting the slab elevation.
- Garage conversions with old slab foundations. Many Carmichael garages sit on unreinforced slabs with no vapor barrier and no footing depth for a dwelling. Converting one into an ADU often means cutting the slab to run plumbing and adding footings to meet county dwelling code, which adds $20,000 to $40,000 to the job.
Pricing for ADU Builders in Carmichael, CA
Here are real numbers for Carmichael’s market. A 750 sq ft detached one-bedroom ADU typically runs $275,000 to $340,000. A 1,200 sq ft two-bedroom unit runs $380,000 to $420,000. A garage conversion runs $140,000 to $200,000 depending on plumbing scope and whether the slab needs work. A junior ADU, a smaller unit attached to or inside the existing home, runs $90,000 to $140,000. Sacramento County impact fees for Carmichael can exceed $20,000 on a detached unit, and that fee is included in the ranges above when we quote, never added later. The two biggest swing factors on Carmichael lots are electrical service upgrades and whether the unit connects to existing sewer or needs its own septic system.

FAQs About ADU Builders in Carmichael
Yes. Carmichael falls under Sacramento County jurisdiction, not Sacramento city, so any detached ADU on an RD-5 lot needs a county building permit, and depending on your parcel, possibly a zoning clearance for setbacks and height limits. The county’s review path is separate from the city’s, with its own fee schedule and its own inspectors. We handle the full county submittal and track it through approval. Call (279) 256-1973 and we’ll check your specific parcel before you commit to drawings.
Septic systems and wells carry county-mandated setback distances from any new dwelling, and those distances dictate your buildable area far more than your lot’s overall size does. If your well sits 80 feet from your preferred ADU location and the county requires 100 feet, that’s a redesign, not a negotiation. We verify these distances during our first site visit, before any design work is paid for. Call (279) 256-1973 and we’ll walk your lot and map the real constraints.
Most Carmichael ranch homes built between the 1950s and 1970s have 100-amp electrical panels, and a modern ADU with a mini-split, kitchen appliances, and laundry can easily draw 60 to 80 amps on its own. A 200-amp service upgrade plus a new panel typically adds $5,000 to $9,000 in Carmichael, and if the SMUD service drop needs trenching across a long driveway, that number climbs. We check your panel and service drop during site feasibility and fold the real number into your written price. Call (279) 256-1973 for an exact quote on your lot.
Yes, but the existing structure has to meet current county dwelling code, which most 1960s garages and shops do not. That usually means new footings, upgraded wall framing, roof insulation, and running new sewer and water lines. The work often costs $140,000 to $200,000 because you’re essentially building a new dwelling inside an old shell. Call (279) 256-1973 and we’ll inspect your outbuilding and tell you straight whether conversion or a new detached build is the smarter spend.
Narrow driveway access and long material hauls add real cost because concrete trucks, lumber deliveries, and crane sets need room to maneuver. On a typical Carmichael flag lot or a home with a 100-foot driveway and tight turn, we may need a pump truck for concrete or a two-piece crane set for a prefab module, which adds $3,000 to $8,000 compared to a wide-open lot. We measure your access during site feasibility and price it accurately the first time. Call (279) 256-1973 for a free estimate that accounts for your actual driveway, not an ideal one.
