Do I need a permit in Port St. Lucie? Fences, sheds, pools, water heaters, roofs and more

Saturday is project day in a lot of Port St. Lucie homes. Maybe it’s a fence for the dog, a shed for the bikes, or a water heater that quit. First ask: does the city need to approve this? This guide covers common jobs inside Port St. Lucie city limits. Fort Pierce and the unincorporated county run their own building departments, so check with them if you live there.

Jobs that need a city permit

The City of Port St. Lucie Building Department posts a separate permit application for each of these common homeowner jobs:

• Fences (a zoning permit)
• Sheds, pergolas, gazebos, tiki huts and detached garages (an “accessory structure” permit)
• In-ground pools, above-ground pools and pool barriers
• Water heater replacement
• Roof replacement
• Air conditioning change-outs
• Exterior windows and doors
• Patio enclosures and aluminum screen enclosures
• Generators, siding and solar systems

If a job has its own form, plan on needing a permit. For bigger jobs, the city also wants a recorded Notice of Commencement when the work is worth $5,000 or more. It must reach the city before your first inspection.

What usually does not need one

Florida’s building code lets small finish work go without a permit. Examples are wallpaper, tile and carpet, and swapping cabinets or countertops without changing the layout, if no electrical or plumbing work is involved. Clearing a clog or fixing a leak is also usually exempt.

A new state law, House Bill 803, took effect July 1, 2026. It tells cities to waive the building permit for some work on a single-family home worth less than $7,500. But there are big limits. It does not cover electrical, plumbing, mechanical, gas or structural work. It does not cover homes in a flood hazard area. You can’t split a big job into small ones to dodge a permit. And it is not automatic: you send the city a written request with a contract or estimate first. Zoning and HOA rules still apply.

Fence rules in Port St. Lucie

• Six feet is the tallest a home fence can be (city code 158.216).
• In the front yard, a fence must sit at least 25 feet back from the front property line, or even with the front corners of the house, whichever is farther back.
• Corner lots have extra setbacks along the side street. Nothing between 2 and 6 feet tall may block the view in the 25-foot triangle at an intersection or within 10 feet of a driveway.
• Chain link, wood, masonry, stone, aluminum, vinyl-coated steel and similar materials are allowed. Chicken wire and barbed wire are not.
• The fence must sit inside your property line. Fences in utility or drainage easements must be easy to remove.
• You must attach a survey or plot plan showing where the fence will go.

If you have an HOA, its rules are separate from the city’s. Get its approval in writing before you buy materials.

Sheds and pools

A shed needs an accessory structure permit. The city asks for a site plan or survey showing where it will sit, and product approval for a pre-built shed. Many sheds also need plans signed by an architect or engineer.

Pools carry extra rules because of drowning risk to young children. Florida’s pool safety law, Chapter 515, says every new home pool needs at least one safety feature: a barrier around the pool, an approved safety cover, exit alarms on doors and windows that open to the pool, self-closing and self-latching doors, or a pool alarm. A barrier must be at least 4 feet tall on the outside, with no gaps a small child could squeeze through or climb. Gates must open outward, away from the pool, and close and latch on their own. In Port St. Lucie, a pool fence must be 4 to 6 feet tall. If your fence will be the pool barrier, it goes in with the pool permit.

Doing it yourself: the owner-builder permit

Florida law lets you pull a permit as your own contractor, called an owner-builder. You must sign a state disclosure that starts, “I understand that state law requires construction to be done by a licensed contractor.” The home must be for your own use. If you sell or rent it within one year after the work is done, the law presumes you built it to sell. You must supervise the work on site yourself. You may not hire an unlicensed person to act as your contractor.

In Port St. Lucie, owner-builders must apply in person and sign at City Hall. The city’s online permit portal is only for licensed contractors. Bring a deed or property card showing your name. Also, a permit expires after 180 days without a passed inspection, so schedule them.

Why it matters when you sell

Florida’s licensing agency warns that missing permits can make a home hard, or even impossible, to sell. An open or never-finished permit can stall a closing.
