How much will it cost before you start to build your new home in Florida (2025–2026)?
The most important question to answer before you start building a home is simple: how much will it cost? To get there, you need a realistic budget built from the best information available.
Below is a clear breakdown of the major cost categories you’ll face when building a home in Florida.
Material Costs
For homes designed with Mended Oak plans, material costs typically run $45–$55 per square foot based on Home Depot and Lowe’s pricing. You may find better deals depending on your suppliers.
If you’re a highly skilled, do‑it‑yourself builder capable of handling every part of construction—from the foundation to the HVAC—this is a good way to estimate your total build cost.
- Dotty's Mrytle (a 550 sq ft ADU): roughly $31,000 in materials
- The Sampson (1800 sf ft 3-Bed 2-Bath): inspired by early 20th‑century Sears home kits, roughly $90,000 in materials
But materials are only part of the picture. There are three unavoidable categories of additional expenses: we'll call these soft costs, utilities, and land. And at the end, we’ll look at a strategy that many use to lower that upfront expense.
Item 1: Soft Costs
Before you break ground, you must pay for the right to build. In Florida, impact fees are the biggest wildcard—they vary dramatically by county, from very low in rural areas to $20,000+ in more populated regions.
Typical soft costs include:
- Site Plans & Surveys: $300–$1,000
- Architectural Plans: $1,000–$5,000+
- Stock plans cost less; custom plans can be significantly higher.
- Engineering Plans: $1,000–$3,000
- Required for every address in Florida to ensure proper wind, gravity, and flood design.
- At Mended Oak, we provide architectural and engineering plans together at a lower combined cost.
- Permits: $1,000–$3,500
- Includes building, electrical, plumbing, and mechanical permits.
- Pre‑Construction Services: $0–$3,000
- May include soil tests, compaction tests, HOA reviews, or additional municipal requirements.
- Impact Fees: $5,000–$20,000
- Most permit offices publish these numbers; every new home triggers an impact fee.
Item 2: Utilities
Florida is flat, but it’s often wet. Fill dirt is a major expense because your slab must be raised to meet code. A monolithic slab is the least expensive foundation type, but it still requires proper elevation.
Typical utility and site‑prep costs:
- Water/Sewer Hookup: $3,000–$8,000
- If unavailable, a well and septic system will cost $12,000–$20,000.
- Electric Hookup: $1,500–$3,000
- Includes temporary power pole and permanent service.
- Gas (usually propane): $500–$1,500
- Site Prep (Clearing & Fill Dirt): $8,000–$15,000
- Driven largely by how much fill is needed to keep water out and meet code.
Item 3: Land
Land prices vary widely. Location is everything.
- In desirable areas, a quarter‑acre lot can cost $150,000 or more.
- In rural areas, small towns, or distressed neighborhoods, lots—even large ones—can sell for $20,000 or less.
Before you start building, you may need to secure the land and pay $22,000–$70,000 upfront. Many people don’t anticipate this cost.
Is There a Way Around These Costs?
Living in a rural area can reduce expenses, though you’re more likely to need a well and septic system.
Another strategy—one used frequently by investors—is to build on land that already has a residence. If there’s an old mobile home or a run‑down house on the property, you may avoid:
- Impact fees
- Many pre‑construction costs
- Some utility connection fees
This can save tens of thousands of dollars.
So keep an eye out for a great deal on an older home sitting on a good piece of land. And when you’re ready, order your signed blueprints from Mended Oak.
