Elk Grove Junior Additional Dwelling Unit Contractor

JADUs Carved Out of Existing Elk Grove Homes

The Junior Additional Dwelling Unit is the fastest, cheapest path to adding a second residence on your Elk Grove 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, Elk Grove 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 Elk Grove 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 City of Elk Grove 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.

Permitting runs through the City of Elk Grove’s Development Services counter, and a JADU application is ministerial under state law: plan check reviews your drawings against the code checklist without a public hearing or discretionary design review. We prepare the floor plan, the Title 24 energy documentation for any newly conditioned space, and the electrical and plumbing sheets, then track plan-check comments through resubmittal so the permit lands without stalled weeks. Because the work stays inside the existing building envelope, there is no site plan review, no lot coverage calculation, and no setback exhibit to argue over. That is a large part of why JADU permits clear faster than any other dwelling-unit path the city offers.

Attached garage conversions deserve a specific note because they are the most requested JADU type in Elk Grove’s tract neighborhoods. Converting the garage means insulating walls and ceiling to current Title 24 requirements, replacing the garage door opening with a framed wall plus a window or entry door, upgrading the slab with a moisture barrier and finished floor, and adding the efficiency kitchen and heating. The city also checks fire separation between the JADU and the remaining living space, smoke and carbon monoxide detector placement, and bedroom egress. Most 1990s and 2000s Elk Grove two-car garages yield roughly 400 usable square feet, comfortably under the 500 sqft JADU cap, with room left for a compact bath.

The owner-occupancy rule trips up more homeowners than any construction detail. State law requires the property owner to live in either the primary residence or the JADU, and the City of Elk Grove records a deed restriction against the property to memorialize it. That restriction runs with the land, so it matters if you plan to sell the home or convert the whole property to a rental later. Adam explains the restriction in plain terms before contract signing, prepares the paperwork with the city, and makes sure it gets recorded with Sacramento County so your final inspection is never held up waiting on it.

Common JADU configurations we build in Elk Grove: 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.
