Tracy Junior Additional Dwelling Unit Contractor
Up to 500 sqft of independent living built inside your existing Tracy 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 Tracy Homes
The Junior Additional Dwelling Unit is the fastest, cheapest path to adding a second residence on your Tracy 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, Tracy 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 Tracy 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 Tracy 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 Tracy: 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).
Tracy has grown fast as a commuter city on the western edge of San Joaquin County, and most of its housing reflects that: large tract subdivisions from the 1990s through today across the north and east side, with two-story production homes on modest lots. Those homes are a natural fit for a JADU because so many were built with a downstairs bedroom and bath or a tandem garage bay that carves out into a 500-square-foot junior unit without ever touching the second floor. For a Tracy household where one adult commutes over the Altamont and another parent or an adult child needs their own space at home, the JADU keeps everyone on one property while giving each side privacy.
Because Tracy is an incorporated city on public water and sewer, the JADU permit runs through the city building department and the utility tie-ins are clean, with no septic to design around. We handle the full submittal: plans, plan check, the building permit, and the plumbing, electrical, and mechanical inspections through final. The newer construction that dominates Tracy usually has electrical service and framing that carry a JADU without much added work, which keeps these builds efficient and on schedule under the ministerial 60-day path.
Tracy gets it from both directions in summer, with hard valley heat and the strong Altamont wind, so we build the envelope to handle both. On a garage conversion we bring the walls and ceiling up to Title 24, air-seal the framed-in garage-door opening carefully against the wind-driven dust, and put a right-sized mini-split or an HVAC tap in the unit so it holds temperature through August. A downstairs bedroom carve-out gets the same treatment on any exterior wall we open. We build every Tracy JADU to be a comfortable, self-contained home for whoever moves in, whether that is family or a long-term tenant.

Six Reasons Tracy 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 Tracy. 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 Tracy lot. Doubles your rental footprint on the same property.

Tracy JADU Questions
How much does a JADU cost in Tracy, CA?
The cost of a Tracy 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 Tracy?
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 Tracy homeowners build both on the same lot.
Do you handle the Tracy 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 Tracy?
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 Tracy 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 Tracy 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.
Do the newer Tracy tract homes work for a JADU?
They work very well. A lot of Tracy’s two-story production homes were built with a downstairs bedroom and bath or a tandem garage bay, and either one carves out into a 500-square-foot junior unit without touching the upstairs. The newer construction usually has the electrical service and framing to carry a JADU without much extra work, so these builds move efficiently on the city’s 60-day path. We add the efficiency kitchen, a private entrance, and an envelope that holds up to the Tracy heat and Altamont wind.
