Fast, Reliable Home Additions & ADU Across Immokalee
Adding square footage in Immokalee means working with a builder who understands this town’s split personality: aging manufactured homes and farmworker housing on one side, newer affordable developments on the other. Most additions and ADUs here fall somewhere between bringing pre-1994 housing up to Collier County wind code and building fresh structures that can stand up to what Irma did in 2017. We’ve walked enough Immokalee lots to know the difference, and we’ll give you a straight answer about what your property can handle. Call (877) 610-1318 and we’ll start with the site.
Why Barrett & Sons Construction Is Immokalee’s Preferred Home Additions & ADU Company
Tom Barrett started this company in 1998, and his sons run the crews. When we work in Immokalee, you’re getting the same owner-operated team that serves Golden Gate and Naples, not a franchise dispatching strangers to your door. The 90-Day Done Right Promise is written on every contract we sign in Immokalee: if something’s not right, one call brings Tom back. We pull permits on every eligible job, and we’ve worked with Collier County inspectors on everything from single-room additions to full ADU builds. The permit inspector works for you, not for me; that’s why I like him. You can look up Tom Barrett’s name, address, and license number before you sign anything. And the phone at (877) 610-1318 gets answered by a live person, around the clock.
Our Home Additions & ADU Services in Immokalee
We’re the Home Additions & ADU team that handles everything from a small interior conversion to a full detached unit with its own electric service. In Immokalee, that range matters because the housing stock is so different from what you’d see in Naples or Bonita Springs. Here’s what we do most often:
ADU Design & Permitting
An ADU in Immokalee has to clear two hurdles: Collier County Florida Building Code and, in some cases, Florida Department of Health agricultural labor camp inspections. That dual track catches contractors who only work in coastal Collier County off guard, and it can add weeks to a build if the sequencing isn’t planned around both agencies. We handle the drawings, the permit set, and the scheduling so the inspection calendar doesn’t slow your project down. Every allowance that isn’t on paper is a surprise waiting for a date, so we put scope, allowances, and change orders in writing before work begins.

Garage Conversion ADU
Converting an attached or detached garage into living space is one of the smartest moves we see in Immokalee, especially on lots where a new foundation isn’t practical. We run into the usual issues on older homes: substandard framing, inadequate hurricane straps, panels that weren’t designed for modern loads. We correct those as part of the conversion rather than covering them up. A garage conversion in Immokalee typically lands between $30,000 and $80,000 depending on whether we’re adding plumbing, upgrading the electrical service, or replacing the garage door opening with impact-rated windows from PGT or CGI.

New Detached ADU
On the flat agricultural land around Immokalee, drainage is the first thing we look at before any detached ADU goes in. The June-October wet season leaves standing water on surrounding fields, so elevated slabs and swale planning are part of our standard scope, not an upcharge. We build detached ADUs from $90,000 to $220,000 in Immokalee, and we’ll show you exactly where that money goes before the first footing is poured. Tom’s sons are on-site most days for these builds; you’ll see the same faces from start to finish.

Junior ADU & Interior Conversion
If you have an oversized primary bedroom, a den, or an enclosed porch that’s already under roof, a junior ADU can add rental income or family space without the cost of a new foundation. Interior conversions in Immokalee often run into wiring and insulation issues in homes built before the 1994 code overhaul, so we plan for those from the start. We’ll bring the space up to code, install proper egress, and handle the kitchenette or bath rough-in if your layout allows it. This is a good path when a full addition feels like too much scope too fast.

Trusted Brands We Service in Immokalee
We don’t install materials we can’t name. On Immokalee ADU and addition projects, our frames get Simonton, Ply Gem, or PGT windows and doors depending on your wind rating and budget. We keep our ordering local and our lead times predictable, because waiting on glass shipments from out of state is not something Immokalee homeowners should have to plan around. If you ask about a brand, we’ll tell you what it costs, how it holds up to the wet season, and whether it’s worth the difference. You’ll get that answer from someone who’s installed it, not from a spec sheet.
Common Home Additions & ADU Problems We See in Immokalee Homes
- Pre-1994 framing and tie-downs. Much of Immokalee’s older manufactured and farmworker housing predates the post-Hurricane Andrew code overhaul. We regularly find missing hurricane straps and undersized anchors that have to be fixed before an addition can legally tie in.
- Standing water during the June-October wet season. The terrain around Immokalee is flat, and drainage around the sites on either side of State Road 29 gets slow when the rain settles in. New additions and ADUs need elevated slabs or re-graded drainage lines, and we plan for that before the permit set goes in.
- Aging electrical panels on older homes. Adding a bedroom or a kitchen means more load on a panel that may have been installed when the house had half the circuits it needs now. We upgrade panels as part of the addition scope, and any price change comes as a written change order before work happens.
- Dual inspection requirements on farmworker housing. Labor camp facilities in Immokalee must satisfy both Collier County permits and Florida Department of Health inspections. Contractors who don’t plan construction sequencing around both agencies end up with multi-week delays. We’ve worked both tracks, and we build them into the schedule from day one.
