Building a House on Your Own Lot in Florida: A Step-by-Step Guide

Owning your lot is a real head start. You've already cleared the hardest hurdle for many buyers — finding land — and with many lenders, the equity in that lot can count toward your down payment. But a lot isn't automatically a buildable lot. The steps below are the ones we walk through with owners across Florida, in the order that saves the most time and money.

Step 1: Confirm the lot is buildable (feasibility)

Before you pick a plan, find out what the lot will actually allow. This is where most surprises — and most budget overruns — start.

• Zoning: confirm single-family use is allowed, plus minimum lot size, density and any overlay districts.
• Setbacks and lot coverage: front, side and rear setbacks and maximum coverage define your buildable footprint.
• Flood zone: look up the parcel on the FEMA Flood Map Service Center. In AE zones, the Florida Building Code generally requires the lowest floor at least one foot above base flood elevation, and many communities require more.
• Utilities: is public water and sewer at the street? If not, plan for a private well and septic system, which need their own permits and site evaluation.
• Soil and fill: a soil test tells your engineer what the foundation needs. Low lots may need imported fill to reach the required elevation.
• Deed restrictions and HOA rules: many Florida subdivisions have minimum square footage, architectural review or material requirements.
• Access, easements and wetlands: a survey will show easements and encroachments; suspected wetlands may require environmental review.

Step 2: Choose your plan — custom or proven model

You have two main routes. A fully custom home is designed around your lot and your life — ideal for unusual lots, views or specific layouts, but with more design time and cost. A proven model plan that's already been engineered, permitted and built is faster to price and permit, and usually lower cost per square foot. Many owners land in the middle: a proven plan with personalized selections and modest changes.

Whichever route you choose, the plan has to fit the setbacks, flood elevation and wind requirements of your specific lot. A plan that worked inland may need different windows, roof connections or a raised foundation near the coast.

Step 3: Build a realistic budget

Your budget has two halves: the house, and everything around it. Typical Florida new construction runs about $150–$180/sq ft in the markets we see, and $200–$300 in higher-cost markets; Hivesta pricing starts at $105/sq ft plus our fee. Then add the items a per-square-foot price usually leaves out.

• Survey, soil testing, engineering and design
• Permits, plan review and impact fees (impact fees commonly run about $10,000–$35,000+ per home, depending on the county)
• Site clearing, fill, grading and driveway
• Well and septic, or utility connection and tap fees
• Landscaping, irrigation and any required sod
• A 5–10% contingency, kept separate from your finish allowances

Hivesta builds on an open-book cost-plus basis: you see every cost, and our fee is a stated percentage of construction cost. Because every project is phased and costs are set out upfront, you know what each phase should cost before it begins. Keeping work in-house and costs controlled is how Hivesta builds often come in 10–15% below market value.

Step 4: Line up construction-to-permanent financing

Most owner-occupants building on their own lot use a construction-to-permanent (one-time close) loan. It funds the build in draws, then converts to a regular mortgage when the home is finished — one application, one closing.

• Lot equity: with many lenders, the appraised value of land you already own counts toward your down payment, subject to the program's rules. If you still owe on the lot, the construction loan can often pay it off.
• Builder approval: lenders review the contractor's license, insurance and budget. Choosing a builder your lender already knows speeds things up.
• Appraisal: the loan is based on the home's completed value, using your plans and budget.
• Draws: funds are released as phases are completed and inspected.

Lenders Hivesta works with include Lake Michigan Credit Union, UWM, Promise Home Loans and The Federal Savings Bank. Requirements differ by lender and program, so compare down payment, rate lock and draw rules before you choose.

Step 5: Permits under the Florida Building Code

Your builder submits plans to the local building department for review. Permits are currently reviewed under the 8th Edition (2023) Florida Building Code; the 9th Edition (2026) takes effect December 31, 2026, and applications submitted on or after that date generally must comply with it.

• Wind design: plans must meet the ultimate design wind speed for your location. In wind-borne debris regions — generally where the design wind speed is 140 mph or more, or within a mile of the coast where it's 130 mph or more — windows and doors need impact protection.
• Product approvals: windows, doors, roofing and other envelope products must carry Florida or local product approvals.
• Energy code: insulation, windows and HVAC must meet the Florida energy code.
• Flood: in mapped flood zones, expect elevation requirements and elevation certificates during and after construction.
• Septic and well: on lots without public utilities, these are permitted separately.

Florida law sets review deadlines for building departments — for many single-family permits, 30 business days once an application is complete and sufficient. In practice, comments and resubmittals mean the full permit process often takes several weeks to a few months, depending on the jurisdiction and how complete the first submission is.

Step 6: Construction phases and inspections

Before the first inspection, a Notice of Commencement is typically recorded with the county — a Florida lien-law requirement for most projects of this size. Then construction moves through phases, each with its own inspections:

On a construction loan, each draw usually follows a completed phase and a lender inspection. Phased budgeting keeps draws and actual costs aligned so there are no gaps.

Step 7: Timeline

Weather, inspection scheduling, utility connections and selection changes are the most common causes of delay. Locking selections before construction is the single best way to stay on schedule.

Step 8: Closeout, certificate of occupancy and warranty

When final inspections pass, the building department issues a certificate of occupancy (CO). Your lender converts the construction loan to the permanent mortgage, and you complete a final walkthrough and punch list. Make sure you receive final lien releases, warranties, product manuals and, in flood zones, the final elevation certificate — your insurer will want it.

Every Hivesta home includes a 3-year extended warranty on top of the warranties Florida law requires. Hivesta is a licensed Florida general contractor (CGC1531741) that builds only single-family homes and townhomes, statewide.
