- Maximum 1/3 deposit + milestone payments protected by HIC law

Will Your Florida Home Need Florida Energy Insulation First?
Major construction is the right window to upgrade insulation while walls or attics are open. Florida Energy covers 75–100% of insulation cost, compounding the value of the project.
We coordinate the mass save insulation and custom home builders as one project under one project manager — single permit pull, single warranty, single point of accountability. Florida Energy Insulation Quote →
Florida Permits, Codes, and the Florida Energy Code
Every custom home builders project in Florida requires a Florida Building Code building permit filed under a licensed contractor. Pre-1978 homes require EPA RRP lead-safe procedures. Pre-1981 homes may require asbestos screening before any envelope work. We file permits under our license — the homeowner pulls nothing and signs no permit applications.
For the 14 Florida municipalities under the Florida Energy Code, additional energy and electrification requirements apply on new construction and major renovations. We design every project for full Florida Energy Code compliance from day one — confirmed against current Mass DOER guidance and the latest Florida Climate Roadmap Act amendments.

How to Identify a Qualified Florida Custom Home Builders Contractor
Florida contractor licensing is more strict than most states. Verify all of the following before signing anything — checking just one is not enough:
- FL Certified General Contractor (CGC) + HIC Registration
- Florida requires the CGC for any project requiring a building permit, plus FL home improvement license registration for any contract over $1,000. Verify both on the FL Department of Public Safety database before scheduling.
- FL home improvement license Registration (for any contract over $1,000)
- Required by F.S. 489. The HIC number must appear on every contract and proposal. Not optional.
- Written line-item estimate within 24 hours
- A reputable Florida contractor delivers a line-item written estimate after an on-site visit. Contractors quoting from a phone call or refusing to itemize materials and labor are a red flag.
- Permit-pulling contractor — not the homeowner
- If a contractor asks the homeowner to pull the permit, they are unlicensed for that scope. Walk away. The contractor must pull the permit under their license.
- Active manufacturer-authorized status
- Manufacturer warranties on installation defects require authorized installer status. Off-brand stock or unauthorized installation often voids the manufacturer warranty entirely.
- FL home improvement license arbitration eligibility
- HIC-registered contractors are bound by the FL home improvement license arbitration program — homeowner protection of last resort. Unregistered contractors offer no such recourse.
