Fast, Reliable Home Additions & ADU Across Naples Manor

Home additions and ADU construction in Naples Manor typically run $45,000 to $220,000 depending on whether you’re adding a room, converting a garage, or building a detached unit from the slab up. Most Naples Manor projects take 12 to 26 weeks once permits clear. That timeline starts with routing your permit through Collier County, not the City of Naples, which surprises plenty of out-of-area contractors and costs homeowners a week or more before drawings even get reviewed. If you’re planning an addition or ADU anywhere in the 34112 zip code, call Barrett & Sons Construction at (877) 610-1318 for a free estimate. We know exactly which county counter your paperwork needs to reach first.

Call (877) 610-1318

We’ve been building in Collier County long enough to know that Naples Manor doesn’t work like East Naples or Naples. The lots are bigger, the septic tanks are older, and the county’s floodplain rules touch nearly every addition out here. That’s local knowledge you can’t fake from a call center in another state.

Why Barrett & Sons Construction Is Naples Manor’s Preferred Home Additions & ADU Company

Tom Barrett founded this company in 1998, and his sons still run the crews. Go look up our license number. Tom publishes his name, his address, and that number on every contract, because the last contractor most Naples Manor homeowners used told them permits were optional. We don’t work that way. Every addition and ADU we build in Naples Manor gets a Collier County permit pulled before a single nail moves, and every inspection gets signed off. The permit inspector works for you, not for me. That’s why I like him.

Homeowners around Naples Manor call us because we answer our own phone, we show up when we say we will, and we put every scope change in writing before work happens. An allowance that isn’t on paper is a surprise waiting for a date. You won’t get surprised at the end of a Barrett & Sons job. We also carry the permanent 10% Senior & Veteran discount, and every job in Naples Manor comes with our 90-Day Done Right Promise. If something’s not right, one call brings Tom back.

Crew members are background-checked and uniformed on every visit. We’re not dispatching strangers from a franchise. The people who frame your Naples Manor ADU are the same faces you’ll see at the hardware store on Saturday.

Our Home Additions & ADU Services in Naples Manor

Naples Manor is an unincorporated Collier County community, which changes how additions and ADUs get scoped, permitted, and built. Our Home Additions & ADU team plans every job around county jurisdiction first, because getting that wrong costs you a week before drawings are even reviewed. Here’s what we handle most often in the 34112 area.

ADU Site Prep & Utilities

Before we quote a detached ADU in Naples Manor, we map the septic drain field, locate the well, and check floodplain elevation. A 1960s CBS lot off a sandy side street doesn’t give you the same setbacks as a City of Naples parcel. We run new subpanels when the existing electrical service can’t carry the load, which is common in homes built when a 60-amp panel was plenty. Collier County floodplain management ordinances frequently require elevation certificates, and we pull those before the county asks.

ADU Site Prep & Utilities

New Detached ADU

A new detached ADU in Naples Manor runs $90,000 to $220,000 depending on size, finishes, and how much site work the lot demands. The long material hauls from East Naples suppliers and equipment access across open lots both factor into the number we put on paper before you sign. We prefer to frame these before the wet season hits, because dewatering an open slab in July costs time nobody planned for. Our crews schedule concrete pours around Southwest Florida’s June-to-September rain pattern.

New Detached ADU

Garage Conversion ADU

Garage conversions in Naples Manor typically run $30,000 to $80,000, but that range swings based on the floodplain review. Your garage slab may sit below the county’s required elevation, which means either raising the floor or adjusting the design. We handle the county review process from the first drawing so you don’t resubmit twice. Most Naples Manor garages we convert were never insulated or wired for living space, so expect new subpanel work and wind-load upgrades to meet current Collier County code.

Garage Conversion ADU

Junior ADU & Interior Conversion

For homeowners who want to age in place or house family, a junior ADU converted from an existing bedroom or den can keep costs under the new-build range. These are easier to permit in some Naples Manor situations because the footprint doesn’t change. But the electrical panel and roof still have to meet current wind-load standards, and we scope that before quoting. If your home still has jalousie windows, we’ll show you what has to change and what can stay.

Room Additions

Adding a bedroom or family room onto a small single-story CBS home in Naples Manor runs $45,000 to $130,000. The concrete block construction is solid, but additions still trigger county energy code review, which means the existing wall assembly and roof insulation get looked at, not just the new square footage. We’ve framed room additions on lots where the septic setback pushed the footprint closer to the house than the homeowner first imagined. That’s the kind of thing you want discovered before concrete gets poured, not after.

Trusted Brands We Service in Naples Manor

When we pour your Naples Manor ADU slab or lay the driveway approach, we specify materials we can stand behind. Belgard and Techo-Bloc pavers hold up to Collier County’s wet season better than the off-brand stuff stacked outside big-box stores. Quikrete concrete products get spec’d for slab pours and footings where consistency matters. And your roof gets GAF or CertainTeed, because a low-pitch 1970s roof in Naples Manor doesn’t forgive cheap shingles. We stock standard materials locally so your job doesn’t idle waiting on a truck from out of county.

Common Home Additions & ADU Problems We See in Naples Manor Homes

Naples Manor’s 1960s to 1980s CBS housing stock gives us a predictable set of problems on nearly every addition or ADU. Here’s what we run into most often.

  • Undersized electrical panels. Homes built with 60-amp or 100-amp service can’t legally feed a new ADU or a modern room addition. We scope a subpanel or full service upgrade before the county reviews your drawings, so the permit doesn’t bounce back twice.
  • Septic setback surprises. A detached ADU sited too close to the drain field or well gets a county denial and forces a redesign. We pull the survey first, confirm the setback, and only then do we frame.
  • Floodplain friction. Much of Naples Manor sits within or adjacent to FEMA Special Flood Hazard Areas. A garage conversion or room addition that raises the finished floor height even slightly can trigger an elevation certificate requirement. We route that early so the county’s floodplain review doesn’t stall the permit.
  • Wrong jurisdiction applications. A contractor applies through the City of Naples portal only to find the job is out of jurisdiction and must resubmit to Collier County. That’s a week lost before drawings get reviewed. We’ve seen it happen to homeowners more than once.

Pricing for Home Additions & ADU in Naples Manor, FL

A home addition in Naples Manor runs $45,000 to $130,000. A detached ADU runs $90,000 to $220,000. A garage conversion sits between $30,000 and $80,000. The spread depends on three things we scope before quoting: site prep, utilities, and county requirements. Long material hauls from East Naples cost more than an in-city job. Equipment access across an open lot costs more than a tight Naples street. And a lot in the floodplain costs more than one on higher ground. We put all of it in the written estimate so the number you hear is the number you sign. Call (877) 610-1318 to schedule a free estimate, and bring any other written estimate you have. We’ll give you a free second opinion on it.

Home Addition $45,000 - $130,000
