Additional Dwelling Units Built for Carmichael Lots
Carmichael’s housing pressure has made the Additional Dwelling Unit one of the smartest moves a homeowner can make. Whether the goal is rental income, a private space for aging parents, or a teenager’s first apartment behind the main house, an ADU adds a second residence on land you already own without the cost or wait of buying a new property in this market.
California state law (Government Code 65852.2) overrides most local restrictions that previously limited ADU construction, and the Carmichael updated its zoning code to comply. On most single-family residential lots in Carmichael, a homeowner can now build a detached ADU up to 1,200 square feet, an attached ADU up to 50% of the primary residence’s floor area, or convert an existing garage or basement into a separate dwelling unit.
ADC Construction handles every type. Adam meets you on the property, walks the lot, and tells you exactly what the Carmichael will and will not permit on your specific parcel. Setbacks, height limits, fire-separation requirements, sewer connections, and utility tap fees are all sorted before the design phase begins, so the project doesn’t stall at the permit counter.
The three most common ADU types we build in Carmichael: detached ADUs (a standalone structure in the backyard, typically 600 to 1,200 sqft, full kitchen, bathroom, and bedroom), attached ADUs (added onto the main house with a separate entrance, often built off the back or side wall), and garage-conversion ADUs (existing detached garage converted to a dwelling unit, often the lowest-cost path).
Carmichael lots vary widely in what they can accommodate. Older neighborhoods tend to have deeper lots with more rear-yard space, which favors detached ADUs with their own driveways or rear-access paths. Newer subdivisions often have shallower rear yards and tighter side setbacks, which makes an attached ADU or a garage conversion the practical answer. Lot coverage maximums, second-story height restrictions, and rear-yard privacy considerations for neighbors all factor in — Adam reviews the parcel map and your jurisdiction’s lot-coverage calculator with you during the quote so the project is sized to what your lot can actually carry.
Adam earned his General B contractor’s license after serving in the US Army, and he built ADC Construction in 2022 on one principle: treat every property like it’s your own home. That standard applies whether the ADU is a $180k garage conversion or a $400k custom detached unit with a covered patio and laundry.

Carmichael ADU Questions
How much does an ADU cost in Carmichael, CA?
Carmichael ADUs typically run $150-$200k for a garage conversion (500-700 sqft), $250-$320k for a mid-size detached ADU (700-1,000 sqft), and $350-$450k for a full 1,200 sqft detached unit with covered patio, laundry, and upgraded finishes. ADC provides itemized quotes within 48 hours of the on-site walk so you know exactly what your Carmichael lot will need.
Do you handle the Carmichael ADU permits?
Yes. We pull every permit required by the local Planning Department and Building Division — zoning clearance, building permit, plumbing, electrical, mechanical, and any encroachment permits for sewer or utility taps — and coordinate inspections through final certificate of occupancy. Permit fees are line-itemed in your quote.
What’s the maximum size ADU allowed on my Carmichael lot?
State law allows up to 1,200 square feet for a detached ADU on most Carmichael single-family lots regardless of local zoning. Attached ADUs are limited to 50% of the primary residence’s floor area, capped at 1,200 sqft. Adam will measure your specific lot and confirm what’s allowed during the on-site quote visit.
How long does an Carmichael ADU build take from design to move-in?
Plan on 8-12 weeks for permits, plans, and engineering before the first shovel hits dirt, then 4-8 months of construction depending on type. A garage conversion is the fastest path (3-5 months building). A custom detached ADU is the longest (6-8 months building). We provide a realistic schedule with your quote and hold to it.
Can I rent out my Carmichael ADU?
Yes. California law requires Carmichael to allow long-term rentals of ADUs on single-family lots. Short-term rentals (Airbnb, VRBO under 30 days) are restricted under local ordinance — confirm current rules with the Planning Department before counting on STR income. Long-term tenant rental is the standard income path most of our Carmichael ADU clients pursue.
