Water Heater Replacement — Florida license requirements
01 The project
The starting point is the work itself — Water Heater Replacement in Florida. The job determines which trades are involved, and the trades determine which license classifications may be required.
No project components are seeded for this project — we do not invent component lists without evidence.
02 Jurisdiction
This project is evaluated for Florida — a state credential (certificate or registration) issued by DBPR through the Construction Industry Licensing Board under F.S. Chapter 489 Part I, plus the LOCAL layers: registered contractors are bound to the jurisdictions where they met local licensing (§489.105(10)), and building permits are issued locally (§489.131(3)(a)). Florida jurisdiction page.
County and city licensing, registration processes and permit fees were not verified for any Florida locality — LOCAL_AUTHORITY_REQUIRED. State requirements are not the complete story for any locality.
03 Trade → license
Relations below are recorded per state — only this jurisdiction's classifications are shown.
Trades involved: no seeded components — trade resolution follows from the classification relations below.
The classification chain for water-heater replacement is NOT determined by the reviewed sources — F.S. §489.105(3) names no water-heater category (SCOPE-FL-WATERHEATER-CLASS-UNDETERMINED, category C). We record that explicitly instead of guessing a classification.
04 Scope
What the official sources say about the work involved — typed assertions, never a boolean "covers". Interpretations are marked as such.
- Not determined water-heater-replacement Classification Selection (requires) F.S. §489.105(3)(m), (f)-(i) S-FL-105 The §489.105(3) definitions read verbatim do NOT name water-heater installation: paragraph (m) lists plumbing work without water heaters, and the air-conditioning/mechanical paragraphs (f)-(i) cover HVAC systems and piping, not water heaters. We therefore do NOT conclude which classification a water-heater replacement requires — category C, recorded explicitly instead of guessed. §489.103(23) presupposes licensing for water-heater repair beyond its narrow apartment-maintenance exemption, and §489.128(1)(a) turns on whether a state license IS required for the scope.

|---|---|---|---|
| Permit issuer must verify state credential; permit systems themselves are local F.S. §489.131(5); §489.131(3)(a),(d) | permit | Any official authorized to issue building or other related permits shall, before issuing a permit, ascertain that the applicant contractor is certified or is registered in the area where the construction is to take place (F.S. §489.131(5)). The permit system itself — systems of permits, fees and inspections, and plan submission and approval — is a power expressly preserved to counties and municipalities (F.S. §489.131(3)(a), (d)), so permit specifics are determined by each local authority, not by the state. | S-FL-131Source S-FL-131 — Florida Legislature (Online Sunshine)Florida Statutes §489.131 — Applicability (local powers, permits, inspections) — F.S. §489.131(5); §489.131(3)(a),(d) Retrieved 2026-10-01 · last verified 2026-10-01 Read verbatim 2026-10-01 (HTTP 200).

06 Local permit layer
The permit issuer must ascertain that the applicant is certified or registered in that area before issuing the permit (F.S. §489.131(5)); permit systems and their fees remain local (§489.131(3)(a), (d)). S-FL-131
Unenforceability guard: a contract entered by an unlicensed contractor is unenforceable and carries no lien or bond claim (F.S. §489.128) — verify status on the official lookup before relying on any outcome here. S-FL-128
