This covers folio numbers starting with 30. The City of Miami, Hialeah, Miami Gardens and the other cities issue their own permits.
What needs a permit and what does not
From the county's Permit Exemptions page (read 24 October 2026):
| Work | Permit? |
|---|---|
| Clearing stoppages; repairing leaks in pipes, valves or fixtures | No |
| Repair work by a licensed plumbing contractor, $500 or less | No |
| By a licensed plumber, any value: faucets; toilet, bidet or urinal fixtures; sink and lavatory fixtures; dishwasher; garbage disposal; shut-off valve on a domestic water line; irrigation repair; pool equipment other than a heater | No |
| Electric water heater up to 50 gallons, by a licensed plumber | No (a higher-wattage replacement needs an electrical permit) |
| Gas appliances other than a water heater, repaired or replaced by a licensed plumber | No |
| Repiping, new fixtures, gas lines, sewer connections, a larger water heater, a gas water heater | Yes |
The Florida House Bill 803 exemption for projects under $7,500 (from 1 July 2026) does not apply: the same page lists plumbing and gas work as always needing a permit.
Who can pull it. Licensed contractors or owner-builders (How to Apply). The county's owner-builder page lists plumbing and gas among the permits an owner-builder may take out on a one- or two-family home for the owner's own use. Note that the no-permit fixture list above is written for licensed plumbing contractors; it is not a homeowner exemption.

The usual declared value, $50,000 (middle half $7,000 to $200,000), is too wide to price a home plumbing job: 39% of these permits are not on homes. Filing stays above average from March to September and dips in November and December. 33176 and 33143 lead. Monthly counts and the contractors named most often are on Miami-Dade plumbing permits; see also Miami-Dade permit statistics and browse Miami-Dade permits.
Before you hire
Check the plumber's earlier county permits with Contractor Permit Inquiry (Miami-Dade building permit search) and the state license (how to check a contractor's license in Florida). Other places' rules: do I need a permit for plumbing repairs and a water heater; labor rates in plumbing labor cost.
What this does not tell you
The county's file has no status and no final date, so we cannot say how many plumbing permits passed final or how long they took, and it begins in November 2024. Exempt fixture swaps never appear in it, so the count understates plumbing work.
How we know this
Exemptions are quoted from Miami-Dade County's Permit Exemptions page, fees from Implementing Order 4-63 (effective 1 October 2026), and the owner-builder, application and inspection rules from the county's Owner-Builder Permits, How to Apply and Inspections pages, all read 24 October 2026. Our counts are the county's Building Permits Issued By Miami-Dade County layer, read 20 October 2026: plumbing and gas permits issued November 2024 to September 2026 on parcels whose folio starts with 30.
Numbers come from public permit records in 57 cities, data through October 20, 2026. Nobody paid to be on this page and nobody can.
