Fast, Reliable Home Additions & ADU Across Englewood
Building a home addition or ADU in Englewood, FL 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 elevation, wind-load requirements, and finishes. The work usually takes three to seven months from permit application to final inspection, and the biggest variable isn’t lumber or drywall; it’s whether your parcel sits in Charlotte County or Sarasota County, because the county line runs straight through Englewood. That single fact changes your permit path, your inspector, your wind-load amendments, and sometimes your entire foundation design. We’re Barrett & Sons Construction, and we’ve been pulling permits on both sides of that line long enough to know which building department answers the phone first. Call (877) 610-1318 and we’ll walk your specific street address through the right process before you spend a dime.
Why Barrett & Sons Construction Is Englewood’s Preferred Home Additions & ADU Company
Tom Barrett started this company in 1998 as an owner-operated outfit, and he still answers his own phone. His sons run the crews, and the name on the truck is the name you’ll see on the job site. For Englewood homeowners who’ve been burned by a national outfit that quoted one number on the phone and slid a different bill across the table, that matters more than any brochure. We live by a simple rule: every scope change, every allowance adjustment, every price change arrives as a written change order before a single nail moves. No surprise invoices at the end. The permit inspector works for you, not for me, and that’s why we like him.
Our Englewood customers call us because we understand this stretch of the Gulf Coast in ways a Miami or Tampa dispatcher never will. We know that a 1960s CBS bungalow on a canal off Manasota Key needs different engineering than a 1990s frame house near South Venice. We know which streets in 34223 fell under Charlotte County’s post-Ian elevation push and which ones in 34224 stayed with Sarasota’s older enforcement posture. A live person answers our phones 24/7, and we offer free second opinions on any written estimate plus no trip charge inside the county. When you call (877) 610-1318, you can ask for Tom by name.
Our Home Additions & ADU Services in Englewood
ADU Design & Permitting
An ADU in Englewood starts with a parcel check before it starts with a drawing. We pull your property records, confirm which county has jurisdiction, and verify your flood zone against current FEMA maps because the maps changed after Hurricane Ian’s 2022 storm surge, and a structure that was legal at ground level in 2015 may now require finished floors elevated on stem walls or pilings. From there we handle stamped engineering, site plans, and the full permit package. Every eligible job includes permits pulled and inspections signed, and we don’t “optional” our way around that.

Garage Conversion ADU
Converting an existing garage into an ADU in Englewood’s 1950s-through-1970s housing stock almost always triggers a deeper conversation about wind-load connectors, impact-rated windows, and flood elevation than a simple remodel would. The garage slab that worked fine for a car often fails current code for a dwelling unit without substantial upgrade work. We price that honestly up front, including the concrete work, Simpson Strong-Tie connectors sized for salt-air exposure, and the fenestration package the county will actually accept. A garage conversion in Englewood typically runs $30,000 to $80,000.

New Detached ADU
Building a new detached ADU in Englewood means designing for a High-Wind Zone on Lemon Bay, where open Gulf fetch pushes wind-load requirements higher than most of inland Florida. Your finished floor needs to sit above base flood elevation, your windows and doors need impact ratings, and your roof fasteners need corrosion resistance that code-minimum galvanized hardware doesn’t provide here. We’ve built these from the ground up in 34223 and 34224, and we specify products like GAF roofing systems and impact-rated Andersen or Marvin windows because we know what the local inspectors want to see. ADU construction in Englewood runs $90,000 to $220,000.

Junior ADU & Interior Conversion
A junior ADU carved out of an existing single-family home in Englewood is often the fastest path to a rental unit or in-law suite, and it typically avoids the full elevation trigger because you’re working inside an already-permitted structure. That said, the interior walls, egress windows, and any new plumbing or electrical still have to pass inspection under whichever county holds your parcel. We handle the interior framing, the Schluter waterproofing in any new bath, and the paperwork. If you’re deciding between a junior ADU and a detached unit, call (877) 610-1318 and we’ll give you straight numbers for both.

Trusted Brands We Service in Englewood
We install brands you can look up, not mystery products off a van. For Englewood additions and ADUs, that means GAF roofing systems rated for the wind speeds this coast actually sees, Andersen and Marvin impact-rated windows that hold up to salt-laden air, and Schluter waterproofing in any new bath or kitchen we build. We keep our supplier relationships close enough that a missing flashing detail on a canal-front project in 34224 doesn’t stall the job for two weeks while someone in a distant warehouse decides whether to ship. If a product fails, we know who to call, and our 90-Day Done Right Promise means Tom comes back and makes it right, one call.
Common Home Additions & ADU Problems We See in Englewood Homes
- Permits pulled from the wrong county. Englewood’s Charlotte-Sarasota county line cuts through residential streets, so a job two blocks from the boundary can sit in a different jurisdiction than the contractor assumed. When that happens, the inspector doesn’t show, the re-inspection fees pile up, and the build loses days. We verify parcel jurisdiction before we submit a single application.
- Ground-level quotes that ignore FEMA AE/VE elevation. Many Englewood homes sit on ground-level slabs from a time before current flood maps existed. A contractor who prices a ground-level addition without accounting for elevation requirements will force a mid-project redesign to pilings or stem walls, and that redesign always costs more than doing it correctly from the start.
- Standard galvanized connectors that rust out in a decade. Salt-laden air off Lemon Bay accelerates corrosion on metal connectors, anchor bolts, and roofing fasteners in ways code-minimum hardware doesn’t anticipate. We specify stainless or thick-coated Simpson Strong-Tie connectors sized for this environment, because a failed inspection or a denied insurance claim after the next storm isn’t worth the $200 you’d save on hardware.
- Impact-rated products omitted to hit a lower bid. Englewood’s High-Wind Zone requires impact-rated windows, doors, and roofing systems, but some quotes quietly leave those off and then present the upgrade as a “surprise” mid-job. A compliant quote includes them from day one. If a number looks too good against everyone else’s, read the window schedule before you sign.
Pricing for Home Additions & ADU in Englewood, FL

What moves the number? Elevation is the big one. A second-story addition over an existing elevated home costs less than lifting a ground-level canal-front bungalow onto stem walls. Impact-rated fenestration, flood-zone engineering, and the corrosion-resistant fasteners this salt air demands all add legitimate cost that a cheap quote simply leaves out. We write every allowance and every change order on paper before the work happens, so the price we quote is the price you pay. Call (877) 610-1318 for a free written line-item estimate on your Englewood addition or ADU.

FAQs - Home Additions & ADU in Englewood
Your permit comes from whichever county your parcel officially sits in, and the only way to know for certain is to verify the parcel number against the property appraiser’s records before applying; Englewood’s 34223 and 34224 zip codes both straddle the county line, so a street address alone doesn’t tell you. We run this check on every Englewood job before we touch a single form. Call (877) 610-1318 and give us your address; we’ll confirm jurisdiction in the same conversation.
Englewood sits in a High-Wind Zone that requires impact-rated windows, doors, and roofing systems designed for the wind speeds of open Gulf exposure on Lemon Bay, and products like GAF roofing systems and Andersen or Marvin impact windows carry ratings that will pass local inspection. Code-minimum galvanized connectors often corrode in this salt air, so we specify Simpson Strong-Tie products sized for coastal exposure. The county inspector signs off only after we provide stamped engineering and product documentation.
Elevating your finished floor above base flood elevation keeps your new living space above the water level FEMA’s current maps predict for a major storm, and it’s the difference between a structure that’s insurable and one that isn’t; many Englewood homes built in the 1950s through 1970s sit on ground-level slabs that no longer comply. Post-Ian rebuilds in the area typically required stem walls or pilings to bring structures into compliance, and we provide the same documentation to your insurer so every penetration is sealed to current wind-load standards. An allowance that isn’t on paper is a surprise waiting for a date, and elevation is never left off our written quotes.
A compliant quote includes the permit application for the correct county, stamped engineering for wind-load and elevation requirements, impact-rated fenestration, corrosion-resistant connectors, and the written change-order process that keeps every allowance transparent until the final inspection; a cheap one quietly omits those and presents them as mid-job extras. We also back every job with our 90-Day Done Right Promise, written on the contract. Call (877) 610-1318 and we’ll walk your specific Englewood property through what applies and what doesn’t, line by line.
Documented wind-load compliance, including stamped engineering, product ratings, and inspection sign-offs, gives your insurer a paper trail showing that the structure met current code when it was built; after Hurricane Ian, Englewood homeowners with that documentation moved through claims far faster than those with nothing on file. On a canal-front street in the Manasota Key area, our crew converted a 1960s ground-level CBS bungalow into a compliant addition by lifting it onto stem walls and tying new Simpson Strong-Tie connectors into the existing block with epoxy anchors sized for salt-air corrosion; the Charlotte County inspector signed off only after we provided stamped engineering for the elevated floor and impact-rated fenestration package, and the homeowner later used our documentation to show their insurer that every penetration was sealed to current wind-load standards. That’s the difference between a file-box rebuild and a year of back-and-forth.
