Why Barrett & Sons Construction Is Country Club’s Preferred Home Additions & ADU Company
We’re the owner-operated crew that shows up with our name on the truck, not a franchise dispatching strangers. Tom Barrett founded this company in 1998, and his sons run the crews. When you call about a room addition in Country Club, you talk to someone who will be standing on your slab within days, not a call center reading from a script.
The homes here are mostly 1940s through 1960s ranch-style builds on conventional slab foundations. That’s our bread and butter.

Our Home Additions & ADU work in Country Club comes with a written 90-Day Done Right Promise: if it’s not right, one call brings Tom back. Permits pulled, inspections signed, every price change on paper before work moves. Ask anyone on your street, or look up the license number yourself.
Our Home Additions & ADU Services in Country Club
Room Additions
A family room bump-out or bedroom addition on a Country Club ranch home means tying new framing into a slab that’s been through six decades of adobe clay heave cycles. We start with that soils report the city requires, then shim and correct for out-of-square rough openings so your new windows don’t bind and your doors don’t leak. Typical range in the 95204: $45,000 to $130,000.

Second Story Additions
Going up instead of out on a Country Club slab home demands a foundation review before design starts, because those telltale diagonal cracks at the window corners tell us exactly what the clay has been doing under your house for the last sixty years. We reinforce before we frame, and every load-bearing correction is priced and approved in writing before we pour.

ADU Design & Permitting
Building an ADU in Country Club means navigating Stockton’s permit office, the soils report trigger, and the utility connection requirements that come with a second address on one lot. We handle the drawings, the permit pull, and the inspection sign-off. You handle deciding which kid gets the unit. Pricing starts around $90,000 for a new detached ADU.

Garage Conversion ADU
Converting a 1950s garage in Country Club into a rentable ADU usually lands between $30,000 and $80,000, but the slab under that garage has been cracking and heaving since Eisenhower was in office. We level what needs leveling, frame what needs framing, and bring the wiring and plumbing up to code before the inspector ever sets foot on site.

Common Home Additions & ADU Problems We See in Country Club Homes
- Diagonal slab cracks at window corners. The adobe clay under Country Club expands every wet winter and contracts every dry summer. Those diagonal cracks are the signature, and they mean your slab is moving. Any addition that ties in without accounting for that movement will crack at the connection point within a few seasons.
- Knob-and-tube and early aluminum wiring. Opening a wall on a 1950s ranch in the 95204 for a room addition frequently exposes wiring that predates modern code. Adding a bedroom that overloads an old circuit will fail electrical rough-in inspection, full stop.
- Asbestos-containing floor tile and duct wrap. Post-war Country Club homes often hide asbestos in the floors and around the ducts. Skipping remediation to save a few thousand dollars triggers a stop-work order when the inspector sees it, and now you’re paying for it anyway plus the delay.
- Galvanized supply piping that’s rusting from the inside. Expanding a bathroom or adding a second-story bath in Country Club means tying into pipes that may be original to the home. If the walls are open and the pipes are shot, we bring you the written change order and you decide before a dollar moves.

FAQs - Home Additions & ADU in Country Club
Because Country Club sits on expansive adobe clay that Lodi’s soil doesn’t share. The city knows a slab here heaves with wet winters and settles with dry summers, so any permitted addition triggers a soils report before design can be approved. It’s not a cost the city wants to add; it’s a cost this ground demands. We budget for it in your first quote so it doesn’t surprise you later. Call (877) 610-1318 and we’ll show you exactly where it sits in the line items.
Plan for $5,000 to $15,000 depending on what’s behind the walls, and we write it in as a line-item allowance before we start. On a 1950s ranch in the 95204, our crew opened a wall for a second-story addition and found knob-and-tube wiring and asbestos floor tile. We rewired to code, remediated the tile, and reinforced the out-of-square slab before framing, with every scope of work and change order approved in writing. The final inspection sign-off came without a punch list surprise because nothing was hidden from the start. That’s the way we run every Country Club job.
We don’t frame on top of a moving slab without correction first. The diagonal cracks at your window corners tell us how the adobe clay has been moving, so we reinforce the foundation and shim the rough openings before any new load goes on. Skip that step and your new second story will pull those cracks wider within a few seasonal cycles. Your permit triggers the soils report, and the soils report tells us the fix.
We schedule concrete pours at dawn during the summer, because Central Valley heat over 100°F dries a pour too fast and causes surface cracking. Spring and fall are the most forgiving seasons for flatwork in Country Club, but we work year-round with adjusted pour schedules. The important thing is that the concrete is laid when conditions say so, not when a sales guy promised a date. Your garage conversion will be scheduled around the weather, because wet winters here reverse the cycle and soften the clay exactly when you don’t want it moving under fresh concrete.
We pull the permits, schedule the inspections, and don’t call the job done until the final sign-off is on file. In Country Club, an ADU permit means the soils report, the structural review, the utility connections, and the final inspection. The permit inspector works for you, not for me, which is why we like him to see everything. You sign the scope, we run the paperwork, and Tom’s name is on it. Call (877) 610-1318 for a free estimate and we’ll walk the property with you before anything is drawn.
