Martin County permits for Port Salerno water heaters
Quick answer
Du-All Plumbing provides water heater installation in Port Salerno, ZIP 34997. Port Salerno is unincorporated, so Martin County issues the water heater permit and requires load calculations for electric tankless units. Call 772-238-6456.
Du-All Plumbing installs and replaces water heaters in Port Salerno, handling the Martin County permit and fitting the unit to older and waterfront homes.
Port Salerno is an unincorporated community in Martin County, so there is no town building department to call. A water heater installation or replacement here is permitted by the Martin County Building Department, which lists water heaters among the projects that require a permit. The County's changeout checklist is written against the 2023 Florida Building Code and asks for the application, the manufacturer's specifications and, for an electric tankless heater, electrical load calculations.
The community grew up in the 1920s on the southern shore of the St. Lucie inlet, and it still has the county's last commercial fishing dock. Around the Manatee Pocket, downtown Port Salerno and the historic New Monrovia neighborhood, housing ranges from older cottages and block homes to waterfront houses and newer infill. That mix is what shapes a water heater job here more than anything else.
In older houses the heater may have been placed wherever there was room when it was added, such as a utility closet, a back porch, a laundry corner or an outside shed. Each location raises different questions. An enclosed porch may need a pan and a drain path that did not exist before. A heater in an outdoor enclosure is exposed to salt air and humidity, which is hard on fittings, jackets and electrical connections, so we look closely at corrosion on the old connections before reusing anything.
We also check the shutoff valves before we drain. On older plumbing a valve that has not moved in years can stick or start to drip when turned, and it is better to know that before the tank is empty.
A like-for-like storage tank swap is the simplest permit and install. The size decision is about first-hour rating: how much hot water the heater delivers in your busiest hour. If the house now has more people, or a bigger tub than it used to, a higher rating may make sense.
Tankless heaters are sized by flow in gallons per minute at a required temperature rise. Federal Building America guidance notes that gas tankless units often need a larger gas line and that the cold water supply, gas service and electrical panel should be evaluated first. In an all-electric house, a whole-house electric tankless heater can demand more capacity than the service has; that is exactly why Martin County asks for load calculations on those units.
Heat pump water heaters work well where there is space and warm air, such as a garage. General DOE guidance points to ample air volume, moderate temperatures and a condensate drain, and the specific model's manual sets the exact air, temperature, duct and drain requirements. A tight closet or an exposed outdoor shed is usually not the right home for one.
Whatever type you lean toward, the decision should come from your house rather than a brochure. We look at where the heater can physically go, what fuel and electrical capacity are already there, how long the hot water has to travel to the main bathroom, and how many people use it at once. Then we give you a straight comparison of the options that actually fit, including the plain like-for-like tank when that is the sensible answer.
It can be. Homes near the Manatee Pocket and the inlet may have elevated living areas, garages on lower levels, or equipment placed to stay above expected water. If your heater sits low in a garage or utility room, we discuss whether the new unit should go on a stand or in a different spot, keeping access for service and a proper drain path. We do not make flood-zone claims about any specific property; if elevation rules apply to your home, the County permit review is where that gets confirmed.
If a boat or trailer is parked in the driveway, please leave a clear path from the street to the heater location so we can carry the old tank out safely.

Rusty hot water, a rumbling tank, water in the pan or a damp base call for a diagnosis, not an automatic replacement. A leaking fitting, valve or element gasket can often be repaired; a leak through the tank shell usually cannot. If you see active leaking, keep clear of hot water, turn off the cold supply to the heater if you can reach it safely, and call. Do not adjust the relief valve, gas control or wiring yourself. Martin County allows emergency equipment replacement with the permit application submitted the next working business day, which lets us restore hot water first and complete the paperwork immediately after.
We confirm the permit, shut off the water and power or gas, and drain the old heater. Before removal we test the shutoff, inspect the supply lines and look for corrosion on fittings and the electrical connection. The new unit is set level, on a pan where the location calls for one, with a relief valve discharge line that runs to an approved spot and is never capped. Electric units get a breaker and wire check against the new rating; gas units get a vent and clearance check under the manufacturer's instructions.
We fill the tank before turning power back on, test every connection for leaks, set a safe temperature and show you the shutoff. The old tank leaves with us. If the old heater leaked into a wall, cabinet or floor, we can arrange a check of where the moisture went before it causes hidden damage. The County inspection follows, and we coordinate access with you.
