Rancho Cordova Junior Additional Dwelling Unit Contractor
Up to 500 sqft of independent living built inside your existing Rancho Cordova 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 Rancho Cordova Homes
The Junior Additional Dwelling Unit is the fastest, cheapest path to adding a second residence on your Rancho Cordova 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, Rancho Cordova 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 Rancho Cordova 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 Rancho Cordova 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 Rancho Cordova: 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).
Rancho Cordova has two distinct kinds of neighborhoods, and both make good JADU territory for different reasons. The older Cordova core off Folsom Boulevard and Coloma Road is full of 1950s and 60s single-story tract homes on flat, deep lots, many with attached garages that convert cleanly into a JADU with a private street-facing entrance. On the newer east side toward Sunridge and Anatolia, the two-story production homes often have a downstairs bedroom-and-bath layout or a tandem garage bay that carves out into a 500-square-foot junior unit without touching the second floor. We match the approach to the house you actually have.
Because Rancho Cordova is an incorporated city, your JADU permit runs through the city’s building and planning department, and the ministerial 60-day path applies. We handle the full submittal: plans, plan check, the building permit, and the plumbing, electrical, and mechanical inspections. The city sits on public water and sewer across nearly all of its neighborhoods, so JADU utility tie-ins are straightforward and there are no septic questions to work through, which keeps these builds moving.
The one thing we never skip on a Rancho Cordova garage conversion is the thermal envelope. Summers here run hard against the triple digits for stretches, and a garage that was never insulated will cook a tenant in July. We bring the walls and ceiling up to Title 24, air-seal the framed-in garage door opening, and put a right-sized mini-split or an HVAC tap in every conversion so the JADU actually holds a comfortable temperature. A converted bedroom suite gets the same treatment on any exterior wall we open. Comfort is what makes a JADU rentable and livable, and we build for it from the start.

Six Reasons Rancho Cordova Homeowners Pick a JADU Over a Full ADU
Lower Cost
A JADU carries a fraction of the budget of a detached ADU because you are working inside walls that already exist. Same rental potential, far less structure to build.
Faster Permits
State law gives JADU applications a 60-day approval ministerial path with the Rancho Cordova. 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 Rancho Cordova lot. Doubles your rental footprint on the same property.

Rancho Cordova JADU Questions
How much does a JADU cost in Rancho Cordova, CA?
What a Rancho Cordova JADU costs comes down to which space you are converting and how much has to change. A bedroom suite with a kitchenette and a shared bathroom is the simplest version, since the room, walls, and roof are already there. A basement conversion with a private bathroom costs more because you are adding plumbing, egress, and often ceiling height or moisture work. An attached garage conversion sits highest, since that space needs insulation, a floor system, and windows before it reads as living space.

What’s the difference between a JADU and an ADU in Rancho Cordova?
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 Rancho Cordova homeowners build both on the same lot.
Do you handle the Rancho Cordova 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 Rancho Cordova?
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 Rancho Cordova 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 Rancho Cordova 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 east-side Rancho Cordova homes work for a JADU?
They can work very well. Many of the two-story production homes toward Sunridge and Anatolia 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. We add the efficiency kitchen, a separate entrance, and the right envelope and cooling for the summer heat. Because the whole east side is on public water and sewer, the utility side stays simple.
