Building a custom home in Florida is exciting, but it also comes with a lot of decisions. Whether you're relocating to the Sunshine State, upgrading from your current home, or building on a lot you already own, this guide covers everything you need to know in 2026.
We've built this guide based on our real world experience as a licensed Florida general contractor (CGC #1537163). This guide gives you practical information that can help you make informed decisions.
Florida's population continues to grow rapidly, and housing demand has pushed existing home prices higher than ever. Building custom gives you significant advantages:
Building and buying have different cost profiles. Compare the complete project cost, including land, fees, financing, site work, and exclusions, with suitable resale alternatives. BuilderK's calculator provides one combined early planning range based on the selections you enter.
The cost to build a custom home in Florida varies by location, size, design complexity, structure, selections, and site conditions. BuilderK's shared Central Florida living area planning rates, last updated July 18, 2026, are:
| Finish Level | Cost per Sq Ft | 2,000 Sq Ft Living Area Subtotal | 3,000 Sq Ft Living Area Subtotal |
|---|---|---|---|
| Standard/Traditional | $160 to $180 | $320K to $360K | $480K to $540K |
| Midrange | $180 to $220 | $360K to $440K | $540K to $660K |
| Custom/Luxury | $220 to $280+ | $440K to $560K+ | $660K to $840K+ |
These are living area examples, not total project prices. The planning calculator provides one combined early range based on the selections you enter. Coastal, flood zone, South Florida, and Southwest Florida projects may cost more. After we review the plan, scope and site, we send a formal proposal.
Discuss an appropriate contingency with your builder and lender. The right amount depends on how complete the plans and selections are, the lot investigation, contract structure, and which risks remain unresolved.
A custom home schedule varies with design development, lender review, permitting, site conditions, material lead times, inspections, and change decisions. Here is how the process works:
Share your vision, budget, lot information, and timeline. We assess the basics and outline a preliminary planning range and the next feasibility checks.
Choose from existing plans or work with our architect to create a custom design. We finalize room layouts, elevations, and specifications.
We connect you with construction loan lenders, prepare builder documentation, and help you get approved before construction.
We handle all permit applications, engineering reviews, and county/city approvals. This typically takes 4 to 6 weeks, depending on the jurisdiction.
Clearing, grading, utility connections, and pouring the foundation. The home starts to take physical shape.
Walls go up, roof is installed, windows and doors are set. The structure is now protected from weather ("dried in").
Electrical, plumbing, HVAC rough installation, drywall, paint, flooring, cabinets, countertops, fixtures. This is where your home comes to life.
County final inspection and Certificate of Occupancy are completed. The lender verifies any conversion conditions, and you receive the keys.
Financing a new construction home is different from buying an existing home. You'll need a construction loan a temporary loan that funds the building process and converts to a traditional mortgage once the home is complete.
A single close structure combines construction financing and a permanent mortgage in one closing. It may avoid a second set of eligible closing costs, but rate lock, conversion, appraisal, completion, and qualification conditions vary by lender and program.

Every new construction project in Florida requires building permits. The permitting process varies by county and municipality, but generally includes:
Florida has some of the strictest building codes in the country, and for good reason. The Florida Building Code requires:
We manage the entire permitting process, from application to final inspection. Our team prepares all documents, coordinates with engineers, and works with local building departments so you don't have to.
Choosing the right construction method is one of the most important decisions you'll make. Here are the three main options for Florida homes:
The most common construction method in Florida. Concrete block walls offer excellent hurricane resistance, fire safety, and thermal mass. They're resistant to termites and stand up well to Florida's humidity. Most lenders and insurance companies prefer block construction.
An emerging alternative that offers speed of construction, termite immunity, and precision engineering. LGS is lighter than block but still provides excellent structural performance. BuilderK is experienced in both CMU and LGS construction.
Common in other states but less popular in Florida due to termite risk and hurricane vulnerability. Wood frame can work for interior walls and second story construction when combined with a block first floor.
| Method | Hurricane Rating | Termite Proof | Cost | Best For |
|---|---|---|---|---|
| CMU Block | Excellent | Yes | $$ | Most Florida homes |
| Light Gauge Steel | Excellent | Yes | $$ | Speed, precision |
| Wood Frame | Good | No | $ | Interior walls, 2nd floors |
A typical custom home schedule in Florida may look like this:
| Phase | Duration | What Happens |
|---|---|---|
| Design & Planning | 2 to 4 weeks | Floor plans, specifications, budget finalized |
| Financing | 3 to 6 weeks, alongside design | Early loan approval and closing |
| Permitting | 4 to 6 weeks | Permit applications, engineering, approvals |
| Construction | 6 to 10 months | Site work and slab, framing, roof, windows and doors, electrical, plumbing and HVAC, drywall, finishes, final inspection and CO |
| TOTAL | 9 to 14 months | From first meeting to keys |
Florida's rainy season (June to September), permit backlogs, material supply chain issues, and inspection scheduling can all add time. Working with an experienced builder who plans for these factors is critical.
BuilderK coordinates design, permitting, and construction, and helps prepare the documents independent lenders request. Here is what you can expect:
