Carmichael Junior Additional Dwelling Unit Contractor
Up to 500 sqft of independent living built inside your existing Carmichael home: converted basement, bedroom suite, attic, or attached garage. Faster permits, lower cost, no impact fees under California state law.
JADUs Carved Out of Existing Carmichael Homes
The Junior Additional Dwelling Unit is the fastest, cheapest path to adding a second residence on your Carmichael property. Where a standard ADU is a new structure built on the lot, a JADU is carved out of the home you already own: up to 500 square feet of independent living converted from an existing bedroom suite, basement, attic, or attached garage. Same kitchen privacy, separate entrance, no detached construction required.
California state law (Government Code 65852.22) requires every city, Carmichael included, to permit one JADU on every single-family residential lot. The conversion must include an efficiency kitchen (sink, refrigerator, and at least one cooking appliance), can share a bathroom with the primary residence or have its own, and requires a separate exterior entrance.
What makes JADUs especially compelling for Carmichael homeowners: no impact fees, no separate utility meters required, and no setback requirements because the unit is inside the existing building envelope. The permit path is faster than a standard ADU, the construction is shorter, and the budget is a fraction of what a detached ADU costs.
ADC Construction handles the full scope: zoning verification, architectural design, structural modifications, kitchen and bathroom installation, electrical and plumbing rough-in, finish carpentry, and Carmichael permits start to finish. The owner-occupancy requirement (one of the units must be owner-occupied) is the only meaningful constraint, and Adam walks you through the deed restriction process with the city as part of the contract.
Common JADU configurations we build in Carmichael: converted master bedroom suite (existing bedroom + private bath becomes a JADU with kitchenette added), basement conversion (finished basement with separate entrance carved out as a JADU), attached garage conversion (single-bay garage attached to the house converted to a livable JADU), and second-story attic conversion (where structural and headroom conditions allow).
Adam earned his General B contractor’s license after serving in the US Army, and built ADC Construction in 2022 on one principle: treat every property like it’s your own home.

Carmichael is full of the kind of home a JADU was practically made for: solid mid-century ranch houses on generous lots, many with an attached garage or a rambling floor plan that gives up 500 square feet of conversion space without much trouble. A lot of the calls we get here are families who want to keep an aging parent close, and a JADU carved out of a spare bedroom suite or a garage lets them do exactly that with a private entrance and a small kitchen while everyone keeps their own space. Because Carmichael sits on Sacramento County sewer and city utilities rather than well and septic, the utility side of the conversion is straightforward and the permit path stays clean.
Those older ranch homes do have their quirks, and we plan for them. Original wiring and panels sometimes need updating to safely carry a second kitchen circuit, plumbing has to be tied into the existing lines cleanly, and an attached-garage conversion means insulating and finishing a space that was never built to be lived in. We handle all of it: the electrical and plumbing rough-in, the insulation and drywall, and a right-sized heating and cooling setup so the JADU stays comfortable through Carmichael’s hot Valley summers. The permit runs through Sacramento County, and we pull it, manage plan check, and carry it through final inspection so you are not chasing the paperwork.
Six Reasons Carmichael Homeowners Pick a JADU Over a Full ADU
Lower Cost
The budget gap is the whole appeal. A JADU converts space you already own, so you skip the foundation, the framing, and the roof that a detached ADU needs.
Faster Permits
State law gives JADU applications a 60-day approval ministerial path with the Carmichael. No discretionary review.
No Impact Fees
California exempts JADUs from utility connection fees, school impact fees, and most development impact fees.
Shared Utilities
No separate water, electrical, or sewer meters required. Utility tap costs drop dramatically.
Shorter Build
JADUs typically complete in 8-16 weeks of construction versus 4-8 months for a detached ADU. Less disruption.
Stack With an ADU
State law allows one JADU AND one ADU on the same Carmichael lot. Doubles your rental footprint on the same property.

Carmichael JADU Questions
How much does a JADU cost in Carmichael, CA?
The cost of a Carmichael JADU depends almost entirely on what the space already has. A spare bedroom that only needs a kitchenette and its own entry is the least involved. A basement with its own bathroom means new plumbing runs, egress windows, and often ceiling work. An attached garage is the biggest lift, since it needs insulation, a floor system, and windows to pass as living space. Adam measures the room on the walkthrough and ADC puts every line in writing before anyone commits. ADC provides itemized quotes within 48 hours of the on-site walk.
What’s the difference between a JADU and an ADU in Carmichael?
An ADU is a new dwelling, detached or attached, up to 1,200 sqft, with its own kitchen, bathroom, and full utility connections. A JADU is carved out of your existing home, capped at 500 sqft, can share a bathroom with the main house, and requires no separate utility meters. JADUs are cheaper, faster, and have no impact fees. ADUs add more rentable space and more equity value. Many Carmichael homeowners build both on the same lot.
Do you handle the Carmichael JADU permits?
Yes. JADUs follow a ministerial 60-day approval path through the the local Planning Department. We submit plans, manage plan check, pull the building permit, coordinate plumbing/electrical/mechanical inspections, and walk through final sign-off. We also prepare the owner-occupancy deed restriction the city requires.
Can I rent out a JADU in Carmichael?
Yes, but with one caveat: California law requires the owner to live in either the main residence or the JADU. You cannot rent out both. Most Carmichael JADU clients continue living in the main home and rent the JADU as an in-law suite, separate apartment for an adult child, or long-term tenant rental. Short-term rentals (Airbnb) are restricted under local ordinance.
How long does an Carmichael JADU build take?
Plan on 4-6 weeks for permits and plans, then 8-16 weeks of construction depending on scope. A bedroom-to-JADU conversion is the fastest (8-10 weeks building). A basement or garage conversion runs longer (12-16 weeks building). We provide a realistic schedule with your quote and hold to it.
Is a JADU a good option for keeping an aging parent close in Carmichael?
It is one of the most common reasons Carmichael families call us. A JADU carved out of a spare bedroom suite or an attached garage gives a parent a private entrance, a small kitchen, and their own living space while staying right next to family. The Carmichael ranch homes usually have the floor plan and lot to make this work cleanly. We can build in the accessibility details that matter for aging in place too, wider doorways, a curbless shower, grab-bar blocking in the walls, so the space works now and years down the road.
My Carmichael ranch home is older. Will the wiring handle a JADU kitchen?
Sometimes it needs an update, and we check that first. Older Carmichael ranch homes were not wired for a second kitchen, so the panel and circuits may need work to safely carry the added load. During the conversion we handle the electrical rough-in, tie the plumbing into the existing lines cleanly, and bring an attached-garage space up to a finished, insulated, livable standard with right-sized heating and cooling. If a panel upgrade is needed we scope it up front so it is part of the plan rather than a surprise mid-project.
