What ADC Construction Delivers
At ADC Construction, ADU construction means more than just completing a job. It means showing up on time, using quality materials, communicating clearly from quote to walkthrough, and standing behind the work long after the crew leaves Lodi.
Adam personally oversees every project. He 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 to a small repair just as much as a six-figure remodel.
If you’ve been burned by a contractor who ghosted you after the check cleared, you’re not alone. We hear it every week. ADC is the answer to that. We pick up the phone after the build. We come back. We fix anything that needs fixing.
Inside an ADC ADU build. An accessory dwelling unit is a complete small house: foundation, framing, roofing, full plumbing and electrical, kitchen and bath, insulation and finishes, built on a lot that already has a home on it. California’s ADU laws have made detached units, attached additions, garage conversions, and junior ADUs one of the most-requested projects we do, for rental income, aging parents, or adult kids staying close.
The part owners underquote is the site, not the structure. Utility tie-ins (whether the unit needs its own water, sewer, and electrical service or branches off the main), setbacks, lot coverage, fire separation, and grading drive both feasibility and cost. We assess all of that on the free site visit and tell you straight what your lot will and will not support before you spend money on plans.
From there ADC carries it end to end as one General B project: design coordination, the ADU permit through the correct local jurisdiction, the full build, inspections, and final sign-off. A garage conversion, a detached new build, and an attached addition are three different scopes. We build all three and scope each honestly rather than steering you to whichever is easiest for us.
On cost: the biggest swing in an ADU budget is rarely the building. It is the site. A garage conversion that reuses an existing slab and roof is one number; a detached unit needing its own foundation, a utility trench, and a panel upgrade is another. We assess your lot’s real constraints on the free on-site visit so the quote reflects what your property actually requires, not a generic per-square-foot guess.

ADUs (Additional Dwelling Units) Questions
How much does ADU construction cost in Lodi, CA?
Cost varies widely based on project scope, material selection, and square footage. ADC Construction provides free, detailed, itemized quotes within 48 hours of your consultation so you know the exact investment before committing.
Are you licensed and insured?
Yes. ADC Construction holds a California General B contractor’s license and full liability insurance. Every project includes permit management, inspections, and warranty coverage.
How long does ADU construction typically take?
Timelines depend on scope. We provide a realistic project schedule with your quote and keep you updated throughout. Most residential projects fall between 1 and 6 weeks depending on complexity.
Do you serve areas outside Lodi?
Yes. We serve 34 cities across San Joaquin, Sacramento, Amador, and Calaveras counties within a 30-mile radius of Lodi, excluding the Bay Area. View all service areas.
Do you build detached ADUs, garage conversions, and attached additions?
All three, plus junior ADUs. They are different scopes with different cost and permitting paths. We walk your lot, explain the realistic options, and build whichever genuinely fits your property and goals rather than defaulting to one type.
How do utilities and permits work for an ADU?
It depends on the unit and the jurisdiction: some ADUs branch off the existing water, sewer, and electrical, others need separate service. We determine what your lot requires, pull the ADU permit through the correct local building department, and handle inspections through final sign-off.
How big can my ADU be, and will it fit my lot?
Size is governed by California ADU rules plus local setbacks, lot coverage, and fire-separation requirements. We assess all of it on the free site visit and tell you what is buildable before you invest in plans.
What if I have issues after the project wraps?
Adam personally answers the phone after every project. If something needs attention, we come back and fix it. That long-term relationship is the reason most of our work comes from referrals and repeat clients.
