Hidden Costs of Building a House in Central Florida (2026)

A builder’s price per square foot covers the house. It usually doesn’t cover everything else: getting the lot ready, permits and inspections, utility connections, interest on the construction loan, and the rules that apply to the land itself. In Central Florida, some of those costs are specific to the state: protected gopher tortoises living on the lot, flood elevation requirements, nitrogen-reducing septic systems near springs, and a property tax bill that jumps once the house is finished. None of them are secret, but they show up after the budget is set, which is why they hurt.

Short version: Before building starts, a Central Florida lot may need:

A boundary survey and flood elevation certificates.
A 100% gopher tortoise survey and, if tortoises are found, a state permit to move them.
A tree removal permit, with replacement fees of up to $530 per inch in Orange County.
Fill dirt to raise the house above flood level.
Water, sewer, or septic connections, a driveway permit, and possibly a charge to bring electric lines to the lot.

Building permits for a 2,000-square-foot home run from about $600 in Polk and Osceola to about $2,500 in Seminole, before impact fees. During the build, you pay interest on the construction loan, and often rent or a mortgage somewhere else. Florida’s lien law means you can end up paying twice if your contractor doesn’t pay subcontractors. After you move in, the property tax usually jumps, because a home that isn’t finished by January 1 is taxed only as vacant land that year.

Getting the lot ready

Surveys, more than once. Counties require a sealed boundary survey or site plan with the permit application, and often more surveys as the house goes up. Brevard’s permit checklist lists a form board survey, a foundation and floor elevation survey, an as-built survey, and a final drainage survey. Inspections can’t be scheduled until each survey is approved. In a flood zone, add elevation certificates prepared by a Florida surveyor or engineer. Volusia asks for one before construction, another once the floor is set, and a final one before the last inspection.

Gopher tortoises. Gopher tortoises are a protected species, and they’re common on the sandy, high ground that makes a good building lot. Before clearing, the Florida Fish and Wildlife Conservation Commission requires a survey of the entire development area, and the survey has to be redone if clearing doesn’t start within 90 days. Landowners can do the survey themselves, but if tortoises are found, they have to be moved under a permit:

Small sites. The permit for sites with 10 or fewer burrows, meant for projects like a single home, carries a $280 mitigation contribution under the 2026 table.
Moving the tortoises. The sites that take the tortoises set their own prices, and most owners hire an authorized agent for the relocation.
Clearing first is expensive. Clearing before the tortoises are moved can trigger a disturbed-site surcharge of $2,096 per tortoise for single-family owners.
It’s a crime. Burying or collapsing a burrow during clearing counts as illegal take, and killing or wounding a threatened species is a felony.

Lots in Florida scrub habitat can also involve the federally protected Florida scrub-jay. In one 2023 Volusia case, a homeowner paid $6,399.54 into a conservation fund before clearing 0.2 acre for a house.

Trees. Clearing a vacant lot usually needs a tree permit, and removed trees have to be replaced or paid for. A 2025 state law lets homeowners remove dangerous trees without a permit, but it only covers lots with a home already on them, so it doesn’t help on a vacant lot.

Orange County. A building permit covers clearing for the house pad, driveway, septic, and 15 feet around the pad. Removed trees go into the county’s tree replacement fund at $106 per inch of trunk for most trees, $318 for specimen trees, and $530 for heritage trees. One 20-inch specimen tree you don’t replace adds $6,360.
Volusia. A tree permit costs $106 plus $26 per tree removed. Vacant lots need a permit.
Seminole. An arbor permit costs $75 per acre, up to $500, with replacement trees required for most removals.

Flood elevation and fill. In a flood zone, the Florida Building Code requires the lowest floor to be at least one foot above the base flood elevation. Lake County requires 18 inches. Raising a house means truckloads of fill dirt or a stem wall foundation. Fill in a floodplain can also trigger “compensating storage” rules: you dig out the same volume of flood storage elsewhere on the site. Lake’s stormwater standards and the St. Johns River Water Management District’s rules both require it.

Wetlands and stormwater. A lot with wetlands on it carries buffers you can’t build in. Orange County’s 2023 wetland ordinance sets a 100-foot undisturbed buffer, reduced to 25 to 50 feet for parcels of 5 acres or less. Building in a wetland needs a county wetland permit starting at $1,765. Larger projects also need a water management district stormwater permit: work in wetlands, more than 9,000 square feet of impervious surface, or a project area over an acre all trigger it, according to the Southwest Florida Water Management District.

The buildable lot checklist and buying vacant land guide cover how to check for these before you buy.

Utilities: getting water, sewer, and power to the lot

Water and sewer. County water and sewer connection fees can add thousands of dollars. The cost to build guide has the numbers by county.

Septic. Without sewer, you need a septic permit from the county health department. In Brevard, a new system permit with site evaluation is $510. In Seminole, it’s $425 plus $125 for the soil profile. The bigger cost is the system itself. In springs and lake cleanup areas, state law requires nitrogen-reducing systems on lots of an acre or less without sewer. Along the Indian River Lagoon, in parts of Brevard and Volusia, they’ve been required on lots of any size since 2024. UF/IFAS says these systems may cost $10,000 or more. The septic and sewer guide explains the rules.

Wells. A private well needs a construction permit, for example $116 from Orange County’s health department, which includes the first bacteria test. The state recommends testing every year. The well and water line permits guide covers the details.

Electric service. Utilities don’t always run power to a new home for free. Under the state’s line extension rule, the utility can charge the cost of the extension minus about four years of expected revenue from the new customer, as described in the Public Service Commission’s 2026 FPL order. A home far from existing lines can face a real bill. Some utilities, including OUC and KUA, require the owner to install the underground conduit. Ask your utility for a quote as soon as you have a site plan. The electric providers guide lists who serves each area.

Driveway and culvert. Connecting a driveway to a county road needs a right-of-way permit:

Volusia: $109.
Brevard: $150.
Polk: $105.
Culverts on ditched roads. On roads with roadside ditches, you’ll usually need a culvert pipe under the driveway. Seminole requires at least an 18-inch pipe with mitered ends.

Permits and inspections

Building permit fees vary a lot by county, because each county calculates them differently. Some charge by square foot. Others charge by the home’s construction value, using different value tables. The approximate building permit cost for a 2,000-square-foot home, not counting impact fees or utility fees:

County	How the fee is figured	About
Polk	$0.30 per sq ft under roof for building and trade permits, plus plan review	$600 to $750
Osceola	Flat fee by square footage, plus plan review, 3% archive fee, and radon fee	$640
Orange	$26 plus $4 per $1,000 of construction value, plus plan review, roof, and trade permits	$1,200
Brevard	$75 plus $3.25 per $1,000 of value, plus application, zoning, and review fees	$1,750
Volusia	$701.60 plus $3.85 per $1,000 of value over $100,000, plus plan review	$1,900
Seminole	$60 plus $5 per $1,000 of value, plus plan review and trade permits	$2,500
Lake	See the county’s current fee schedule	Varies

Domuncula estimates from each county’s published fee schedule, October 2026. Orange values a wood-frame home at $97 per square foot under its own table. Brevard, Volusia, and Seminole are estimated at $170.80 per square foot, the International Code Council’s August 2025 national figure. Polk’s schedule dates from 2017. A higher contract price raises value-based fees.

On top of the permit:

State surcharges. Florida adds two surcharges to permit fees, 1% and 1.5%.
Re-inspection fees. A failed inspection costs money and time: $76 in Orange, and in Seminole $50 the first time and up to $150 for repeats.
Energy code tests. Florida’s energy code requires new homes to pass a blower-door air leakage test and a duct leakage test, done by a certified energy rater or a licensed air-conditioning or mechanical contractor. Ask who pays for them.
Impact fees. These are the biggest fee on most new homes, from about $9,800 to $37,700 depending on the county. The impact fees by county guide has the full numbers.

The money side: loans, time, and contingency

Construction loan interest. During the build, you pay interest on the money drawn so far, not the full loan. Lenders estimate it assuming about half the loan is outstanding on average. On a $350,000 construction loan at 7.5% that’s drawn down over nine months, that’s roughly $9,800 in interest before the house is finished. Most owners are also paying rent or a mortgage on where they live now.

Time limits. Delays cost more than interest. Fannie Mae’s single-closing construction loans allow no more than 12 months for any construction period and 18 months total, and “exceptions are not granted.” If the finished home appraises for less, the borrower may have to requalify. Builds do run long. Census data for 2025 shows that in the South, 19% of contractor-built homes and 29% of owner-built homes took 13 months or more from start to finish.

Change orders and allowances. Every change you make after the contract is signed, and every allowance for cabinets, flooring, or fixtures that runs over, gets added to the price. No official source tracks how often custom builds go over budget. A sensible plan is to hold back a contingency of at least 10% of the construction cost and not commit it until the house is finished.

What’s built into a builder’s price. In NAHB’s 2024 cost survey, financing was 1.5% of a new home’s average price and overhead 5.7%. When you build on your own lot with a custom builder, some of those costs move to you directly.

The mortgage and financing basics guide covers loan types.

Florida lien law: how you can pay twice

Under Florida’s construction lien law, subcontractors and suppliers who aren’t paid can put a lien on your home, even if you’ve already paid your contractor in full. Contracts over $2,500 must include a warning saying exactly that. The protections are paperwork, and they’re the owner’s job:

Notice of Commencement. For jobs over $5,000, it must be recorded and posted before the first inspection. Recording costs $10 for the first page and $8.50 for each additional page. It expires after a year by default, and payments made after it expires can leave you paying twice.
Notices to owner. Subcontractors and suppliers send these within 45 days of starting work. Keep every one.
Lien releases. Before each payment, get releases from everyone who sent you a notice. Before the final payment, get the contractor’s final affidavit listing anyone still unpaid.

If a licensed contractor’s misconduct costs you money, Florida’s Homeowners’ Construction Recovery Fund pays up to $100,000 per claim for general, building, and residential contractor contracts signed since July 1, 2024. You need a court judgment or award first, and the state calls the fund “a last resort.”

Building it yourself: the owner-builder rules

Florida lets owners act as their own contractor under the owner-builder exemption:

You sign for the permit. You must sign the permit application in person and supervise the work on site.
You’re the responsible party. You’re liable for code compliance, for hiring only licensed subcontractors, and for workers’ compensation and tax withholding on anyone you employ directly.
One-year rule. Selling or renting the home within a year of completion creates a presumption that you built it to sell, which isn’t allowed under the exemption.
Expect a longer build. Owner-built homes take longer, about 10.4 months on average in the South compared with 9.2 for contractor-built homes, which means more interest and more rent.

The tax bill after you move in

Budgets often use the property tax on the vacant lot, and that number is about to change. Under F.S. 192.042, a home that isn’t substantially finished on January 1 isn’t taxed that year, so the first bill may cover only the land. The next January, the full home is added at market value. Homestead’s Save Our Homes cap starts from the value as of January 1 of the year you first get the exemption. As the Seminole County Property Appraiser puts it: “Do not rely on current taxes as an estimate.” The true monthly cost calculator estimates the full tax on a finished home, and the homestead exemption guide covers how to file.

Hurricane code items

All new homes are built to Florida’s wind code, which is part of the base price. The extra cost comes in the wind-borne debris region: within a mile of the coast where design wind speeds reach 130 mph, or anywhere they reach 140 mph. Homes there need impact-rated windows and doors, or approved shutters, which affects much of coastal Brevard and Volusia. The Florida Building Commission is also studying whether to add areas around large inland lakes, including Apopka, Harris, Dora, Conway, Tohopekaliga, and Kissimmee. A May 2026 draft report recommends doing so, but it isn’t code yet. The state’s My Safe Florida Home grants don’t apply to new construction, since they cover only homes built before 2008. The hurricane code and wind zones guide has the details.

After the certificate of occupancy

A few costs show up after final inspection, because they’re often not in the contract:

Outside: landscaping and sod, irrigation, fencing, a mailbox.
Inside: window coverings, and appliances if they’re not included.
Community fees: architectural review fees if the lot is in an HOA.

Ask your builder for a written list of what is and isn’t included before you sign. The new construction buyer mistakes guide covers the contract side, and the tiny homes guide covers building small.

Before you sign: a hidden costs checklist

Get the lot’s survey, flood zone, and wetlands checked before you buy, and price fill dirt if the lot sits low.
Survey for gopher tortoises within 90 days before clearing, and get the permit first if any turn up.
Check the tree rules with the county, and count specimen trees on the lot.
Get utility quotes in writing: water and sewer connections, or a septic site evaluation and system price; an electric line extension quote; and a driveway permit, including whether you need a culvert.
Add up permit fees and impact fees for your county.
Price the financing: interest during the build, rent while you wait, and the construction loan’s time limits.
Set up lien protection: Notice of Commencement, notices to owner, and lien releases before every payment.
Hold a contingency of at least 10% of the construction cost.
Budget the property tax on the finished home, not the vacant lot.

Frequently Asked Questions

The most common ones are surveys and elevation certificates, gopher tortoise surveys and permits, tree removal and replacement fees, fill dirt in flood zones, septic or utility connections, electric line extensions, driveway permits, building permit and impact fees, construction loan interest, change orders, and a higher property tax bill once the home is finished.

For a 2,000-square-foot home, building permit fees run from about $600 in Polk and Osceola to about $2,500 in Seminole, based on each county’s fee schedule. Impact fees are separate and much larger, from about $9,800 to $37,700 depending on the county.

Yes, if the land could have gopher tortoises. FWC requires a survey of the entire development area before clearing, redone if clearing doesn’t start within 90 days. If tortoises are found, they must be relocated under an FWC permit before work starts. Destroying a burrow during clearing is illegal.

Usually, on a vacant lot. Counties such as Orange, Seminole, and Volusia require tree permits for clearing and charge replacement fees for removed trees, up to $530 per inch for heritage trees in Orange County. A building permit in Orange County covers clearing for the house pad, driveway, and septic.

A home that isn’t substantially complete on January 1 isn’t taxed that year, so the first bill may cover only the land. The following year, the finished home is added at its full value, which can raise the bill several times over.

It’s a document recorded with the county and posted at the job site before the first inspection on jobs over $5,000. It protects the owner under Florida’s lien law. Recording costs $10 for the first page and $8.50 for each additional page, and it expires after one year unless it says otherwise.

Yes, under the owner-builder exemption, if you sign the permit in person, supervise the work yourself, and live in the home. Selling or renting it within a year of completion creates a presumption that you built it to sell. You’re responsible for code compliance and for any workers you hire.

Census data for the South shows contractor-built homes averaging about 9 months from start to completion and owner-built homes about 10 months. In 2025, 19% of contractor-built homes and 29% of owner-built homes in the South took 13 months or more.
