Quick answer

Seminole County's Storm Damage Repair guidance lists replacement of a water heater among the work that requires a building permit, backed by the fee schedule's dedicated plumbing permit fee. Stopping a leak without replacing concealed piping, and clearing a stoppage or repairing a leak in a pipe, valve, or fixture without replacing or rearranging piping, are exempt. This applies to unincorporated Seminole County; the cities of Sanford, Altamonte Springs, Casselberry, Lake Mary, Longwood, Oviedo, and Winter Springs operate their own building departments.

How to apply in Seminole County

You apply for a residential plumbing permit at your local building department by filing an application that describes the scope of work and site, along with construction documents, before any regulated plumbing installation, alteration, or repair begins. Minor repairs that do not touch piping or fixtures are generally exempt, and once issued the permit only stays valid if work is started within its time limit.

What most plumbing permit applications include:

  • A permit is required before any owner or authorized agent constructs, alters, repairs, removes, converts, or replaces a plumbing system regulated by the code (IRC R105.1).
  • The application must identify and describe the work, describe the site, state the intended use and occupancy, and be signed by the applicant or an authorized agent (IRC R105.3).
  • Two or more sets of construction documents must accompany the application, drawn with enough clarity to show the location, nature, and extent of the proposed plumbing work and how it will conform to code (IRC R106.1, R106.1.1).
  • Minor plumbing repairs, such as clearing a stoppage or removing and resetting a water closet without rearranging pipes or fixtures, are exempt from permit (IRC R105.2).
  • Once issued, a permit is only valid for a limited window, commonly 180 days, and becomes invalid if the work is not started or is abandoned within that time, though extensions can be requested (IRC R105.3.2, R105.5).

Inspections and closing out your permit

Plumbing inspections are timed to whatever is about to hide the pipe: underground and under-slab piping is checked before concrete covers it, rough-in piping is pressure or water tested before walls close up, and a final inspection checks every fixture and backflow protection once the work is complete.

  1. Piping and equipment placed under a slab or floor must be in place and inspected before any concrete is poured or floor sheathing is installed over it (IRC R109.1.1.1).
  2. Rough plumbing, along with the mechanical, gas, and electrical rough-in, must be inspected prior to covering or concealment and before fixtures or appliances are set (IRC R109.1.2).
  3. Rough drain, waste, and vent (DWV) piping is tested with water, air, or (for plastic piping) a vacuum, and must show no evidence of leakage before it is closed in (IRC P2503.5.1).
  4. The water-distribution piping is tested and must hold tight under the system's working pressure, or under a 50 psi air test for non-plastic piping, before it is concealed (IRC P2503.7).
  5. The framing inspection cannot proceed until the plumbing rough inspection, along with the mechanical and electrical rough inspections, has been approved (IRC R109.1.4).
  6. At the final drainage test, each fixture is filled and then drained, and its traps and fixture connections must prove watertight by visual inspection (IRC P2503.5.2).
  7. Final inspection is made after all work required by the permit is complete, and includes confirming backflow protection, such as vacuum breakers on hose bibbs, is installed (IRC R109.1.6, P2902.4.3).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Seminole County permit portal or by phone at 407-665-7050.

Where do you apply for a plumbing permit in Seminole County?
You can apply through the Seminole County permit portal or contact the Building Division directly. The links are listed on this page.
Can a homeowner pull a plumbing permit themselves in Seminole County?
Under Florida law (F.S. 489.103(7)(a)-(c)): Florida lets you pull your own permit as an owner-builder under section 489.103(7), Florida Statutes, which exempts property owners from the contractor licensing law when they act as their own contractor and provide direct, onsite supervision of all work not performed by licensed contractors. The exemption covers building or improving a one-family or two-family residence or a farm outbuilding for your own occupancy or use, and commercial buildings only up to a $75,000 cost, and the property may not be built or improved for sale or lease. If you sell or lease the property within 1 year after completing the work, the law presumes it was built for sale or lease, which violates the exemption. To qualify, you must personally appear and sign the building permit application and sign a state-prescribed disclosure statement acknowledging that you are the party legally and financially responsible for the construction, that you must provide direct, onsite supervision, and that unlicensed people you use must be your own employees, bringing federal tax withholding and workers' compensation obligations. You may not hire an unlicensed person to act as your contractor and may not delegate supervision to anyone who is not licensed for the work being done; if these requirements are violated, the local permitting agency shall withhold final approval, revoke the permit, or pursue unlicensed-activity remedies. A separate narrow branch of the exemption also lets an owner take over and complete a permit on a one-family or two-family residence when the original contractor substantially completed the project. Confirm how Seminole County applies this before you apply.
