Home Additions & ADU in Pelican Bay - One Fixed Price, Permits Handled

Fast, Reliable Home Additions & ADU Across Pelican Bay

A home addition or ADU in Pelican Bay typically runs between $45,000 and $130,000 for a room addition, while a full detached ADU starts around $90,000 and can reach $220,000 depending on scope. The project will require two separate approvals: one from Collier County and one from the Pelican Bay Foundation’s Architectural Review Committee. Most homeowners wait until both are in hand before we order a single board of lumber.

We’re Barrett & Sons Construction, and we’ve spent nearly three decades in Florida’s high-end coastal communities. Around Pelican Bay, that means knowing how the Foundation’s submittal calendar works, which window specs survive a direct Gulf summer, and which foundation details the county will sign without a second look. Tom Barrett owns the company, his sons run the crews, and a live person answers the phone when you call.

Why Barrett & Sons Construction Is Pelican Bay’s Preferred Home Additions & ADU Company

Tom Barrett has been putting his name on construction jobs since 1998, and around a place like Pelican Bay, that actually means something. The Pelican Bay Foundation keeps a tight rein on what gets built here, and they’re quicker to approve a submittal that shows a contractor who’s been through their process before. We have. We know the ARC meets on its own calendar, not yours, and we know how to get informal staff feedback before finalizing documents so you aren’t sitting through a second review cycle because of a window trim detail nobody caught.

The permit inspector works for you, not for me. That’s why I like him. We pull permits on every eligible job in Pelican Bay, and we treat the Foundation’s review as a parallel track rather than an afterthought. Local homeowners have told us about other contractors who treated the Foundation’s rules as a surprise to be discovered later. We don’t work that way. Every scope item, every allowance, and every price change arrives as a written change order before work happens. An allowance that isn’t on paper is a surprise waiting for a date.

Our Home Additions & ADU team includes Tom’s sons and crew members who carry the Barrett & Sons name. They’re background-checked, uniformed, and on-site most days. For Pelican Bay homeowners, that matters because the crew that frames your addition is the same crew Tom will send back if anything isn’t right. We back every job with the 90-Day Done Right Promise, written on the contract, not buried in fine print. One call brings Tom back.

ADU Design & Permitting

Designing an ADU in Pelican Bay means starting with the Foundation, not the building department. Their pre-approved material palette sets the visual tone, and their submittal calendar dictates when your project gets heard. We’ve shepherded projects through both tracks enough to know that getting informal staff feedback before finalizing design documents saves a full review cycle. On the county side, units near the Gulf-facing corridor sit in FEMA V-zone or AE flood designations, which means elevated foundations and flood-resistant assemblies are non-negotiable. We design for those constraints from day one, not as a correction later.

Garage Conversion ADU

Converting a garage in Pelican Bay works best on the larger inland estate lots where the original structure was overbuilt by 1980s and 1990s custom-home standards. You’re not fighting the condo tower limitations that govern the high-rises along the western corridor. A garage conversion here typically runs $30,000 to $80,000, and the Foundation will want to see how the new living space interacts with the street elevation. We pull permits, handle the ARC submittal, and install impact-rated windows that meet code and the Foundation’s aesthetic standards.

New Detached ADU

A new detached ADU on a Pelican Bay lot is a serious undertaking, usually $90,000 to $220,000 by the time you account for foundation work, hurricane-rated envelope systems, and Foundation-approved exterior finishes. The sandy soils and high water table near the coast demand careful drainage and structural design that looks nothing like what works inland in Collier County. We spec stainless or hot-dipped galvanized connectors even on interior framing near the Gulf because salt-laden air eats unprotected metal faster than most people expect. Brands like PGT and CGI show up in our window and door packages because they’re built for exactly this environment.

Junior ADU & Interior Conversion

A junior ADU carved out of existing square footage is often the most practical path for Pelican Bay owners who want rental income or multi-generational space without expanding the footprint. The Foundation tends to view interior-only work more favorably, and the county permit path is shorter when you’re not pushing a new foundation into the ground. Still, every eligible job gets permits and inspections. We’ve done enough of these in Pelican Bay to know where the load-bearing points are in the 1980s-era homes, which helps us frame the plan accurately the first time.

Trusted Brands We Service in Pelican Bay

We put premium brands into Pelican Bay projects because the environment doesn’t forgive cheap materials. For impact-rated windows and doors on additions and ADUs, we install PGT, CGI, and Simonton products, all built for South Florida wind loads and salt exposure. These are materials you can look up and verify, not mystery brands off a van. When we run into an existing window or door from one of these manufacturers that needs service or replacement during your project, we know the product lines well enough to match models and hardware without guesswork.

Common Home Additions & ADU Problems We See in Pelican Bay Homes

• Salt corrosion on connectors and fasteners. Direct Gulf exposure sends salt-laden air deep into framing cavities. We spec stainless or hot-dipped galvanized hardware on every job, even interior work near the beachfront corridor, because replacement 15 years in is far more expensive than doing it right now.
• Foundation movement in sandy, low-bearing soils. Pelican Bay’s inland lots sit on sand that shifts with summer downpours and standing water. We design footers and drainage for that reality, which is different from what works just a few miles inland in Naples.
• ARC submittal rejections over material choices. The Pelican Bay Foundation maintains a pre-approved palette, and contractors unfamiliar with it lose weeks waiting for denial letters. We get informal staff feedback before finalizing documents so your project doesn’t stall before it starts.
• Post-Ian code upgrades catching homeowners off guard. Since Hurricane Ian in 2022, Collier County and the Foundation have tightened requirements for impact-rated openings, elevated mechanicals, and flood-resistant assemblies. Some older Pelican Bay homes were built to standards that wouldn’t pass today. We flag those items in the estimate so there are no surprises at inspection.
