Gulfport Plumbing Permit Cost
Gulfport plumbing permits are priced by Building Code Services from the department's plumbing fee schedule.
Every permit pays the $30.00 base fee, then the fixture list: $5.00 per standard fixture (water closets, sinks, tubs, showers, disposals, dishwashers, washing machines and more), $7.00 for lavatories and floor drains, $10.00 for water heaters and heating appliances, $50.00 for a water connection — the list's largest row — and $15.00 for a backflow preventer. Sprinkler heads price at $10.00 for the first five and $2.00 each after. The schedule carries an FY 2002 column heading, which the page states plainly.

What is different in Gulfport
Plumbing permits cover fixture installations and replacements, water and sewer connections, water heaters, gas service lines ($10.00), sprinkler systems and backflow prevention. Permits go to bonded master plumbers, and inspections are performed by Building Code Services; work covered before inspection must be uncovered. On the Mississippi Gulf Coast, backflow prevention and proper drain priming matter — the schedule prices trap-primed floor drains at $10.00 against $7.00 unprimed.
What this figure does not include
Impact fees, utility connections and other departments’ permits are the usual omissions, and in some jurisdictions they are larger than the permit fee itself.
Not included in these figures
This estimate covers the City of Gulfport plumbing permit fees only. It excludes:
- Water and sewer tap and connection charges billed by Gulfport's water utility — the $50.00 schedule row is the permit fee for the connection work, not the utility's tap charge.
- Building, electrical and mechanical permits for the same project.
- Gas company meter and service charges (the $10.00 row prices the gas line permit itself).
- Harrison County septic permits for property outside the sewer service area.
- State plumbing licensing fees.
What you need before applying
- Licensed, bonded plumbing contractorRequired
Plumbing permits are issued to bonded master plumbers; advertising as a licensed contractor without the proper City license is unlawful under the ordinance the department administers.
Common questions
How is a Gulfport plumbing permit fee calculated?
The $30.00 base fee plus a per-item charge from the fixture list: $5.00 for each standard fixture or appliance, $7.00 for lavatories and floor drains, $10.00 for water heaters and heating appliances, and specific amounts for connections and devices. A bathroom remodel with a toilet, tub, disposal, lavatory and water heater runs $30.00 + $15.00 + $7.00 + $10.00 = $62.00.

What counts as a $5.00 fixture in Gulfport?
The schedule's five-dollar rows: fixtures generally, water closets, sinks, bath tubs, grease traps, urinals, laundry tubs, sewer connections, showers, water fountains, dishwashers, disposals, washing machines, swimming pools, kitchen ranges, hot plates and boilers.

How much is a water heater permit in Gulfport?
$10.00 — the schedule prices both 'Water Heater/full auto' and 'Water Heater/Instant' at that amount — plus the $30.00 base fee, so a water heater alone is a $40.00 permit.

Why is the water connection row $50.00?
The water connection is the schedule's largest plumbing row — five times a standard fixture — because it covers tying a building into the city's water system. It prices the permit for the connection work; the water utility's own tap and meter charges are billed separately.

How are sprinkler heads priced on a Gulfport plumbing permit?
$10.00 covers sprinkler heads one through five, and each additional head is $2.00 — so a ten-head system is $10.00 + 5 × $2.00 = $20.00, on top of the $30.00 base fee.

What does a floor drain cost to permit in Gulfport?
$7.00, or $10.00 with a trap primer. The schedule prices the primed version $3.00 higher because the primer device is additional equipment the inspector verifies.

How much is a gas line permit in Gulfport?
$10.00 per gas service line, plus the $30.00 base fee. The same plumbing sheet carries the row — Gulfport permits gas piping through Building Code Services rather than through a separate gas board.
