Stuart emergency water heater permits and Martin County addresses
Quick answer
Du-All Plumbing provides water heater installation in Stuart. Inside city limits, a water heater replacement may proceed as an emergency repair with the permit application filed the next business day; unincorporated addresses follow Martin County. Call 772-238-6456.
Du-All Plumbing replaces and installs water heaters in Stuart, from older homes near downtown to newer houses outside city limits. We file the right permit for your address.
Stuart is one of the few places we work where the city spells out what to do when a water heater dies on a weekend. The City's Building Division lists water heater replacement among the emergency repairs that may be performed without prior approval. The catch is the paperwork that follows: a permit application has to go into the City's OpenGov portal the next business day, and the permit is required within 24 to 48 hours of finishing the repair. The application must come from a registered, licensed contractor, although a homesteaded owner may apply for their own water heater permit.
That rule covers addresses inside city limits. Stuart mailing addresses also stretch into unincorporated Martin County, where the County Building Department handles the permit and lists water heater installation and replacement among projects that require one. The first useful question for any Stuart job is simply which side of the city line the house is on.

Some homes with a Stuart address in ZIP codes 34994, 34996 and 34997 sit outside the city. The City's utility, for example, serves about 4,000 households across roughly 3.4 square miles, a fraction of the area that uses the Stuart name. Your property tax bill or the property appraiser's record shows whether you are in the City or the County.
In unincorporated Martin County, the County checklist for a water heater changeout or new installation references the 2023 Florida Building Code and asks for the permit application, manufacturer specifications and, for tankless electric units only, electrical load calculations. That last item exists because a whole-house electric tankless heater can overload a service that was fine with a tank. We prepare whichever set of paperwork your address requires.
Stuart was settled in 1870 and incorporated in 1914, and some of the housing near downtown and along the older east side streets reflects that age. In those homes the heater may be in a small utility closet, a back porch enclosure or an attached garage that was added later. Older supply valves may be stiff or fail when turned, so we check the shutoffs before draining anything. We also check circuit sizing and whether a drain pan is present, since an older installation may predate current expectations.
Newer construction usually has easier access and a planned location, but it is not automatic. A heater boxed into a tight closet still has to be removed in one piece and the new one carried in without scraping walls. We measure the doorway and the space before the day so there are no surprises.
Where a heater sits a long way from the main bathroom, you wait longer for hot water no matter what type you choose. If that bothers you, mention it; moving the heater is not always practical, but it is worth discussing during a planned replacement rather than an emergency.
Think about your busiest hour, not your average day. For a storage tank, the first-hour rating tells you how much hot water it can supply in that hour starting full. Two people who shower at different times can do well with a modest tank; a family getting ready at once may need a higher rating or faster recovery.
For tankless units, add the gallons per minute of fixtures that run together and check the temperature rise the heater can deliver at that flow. Federal Building America guidance on tankless installs also stresses checking gas line capacity, the cold water supply and the electrical panel before committing, and notes that many gas units need a larger line than a tank. A heat pump water heater is a third route if you have a garage or large utility space; General DOE guidance points to ample surrounding air, moderate room temperatures and a condensate drain, while the exact requirements come from the chosen model's installation manual.

Keep children and pets away from hot water. If you can reach the cold water valve on top of the heater safely, turn it off. Do not touch the gas control, wiring or the relief valve. Then call us. If you are inside city limits, Stuart's emergency rule lets a licensed contractor replace the heater first and file the permit application immediately after.
A dripping relief valve discharge pipe is a sign of a pressure or temperature problem, not something to plug or cap. Leave it alone and have it checked.
We start by turning off the water and the power or gas, draining the old tank and checking the shutoff valve as it closes. The new heater goes on a drain pan where the location calls for one, with new supply connectors and a relief valve discharge line that runs to an approved termination. Electric heaters get a check of breaker and wire size against the new unit's rating. Gas heaters get a check of the vent connection, clearances and combustion air under the manufacturer's instructions. We fill the tank completely before restoring power, because energizing an empty electric tank can burn out an element. Then we test for leaks, confirm the temperature setting and show you where the shutoff is.
Old tanks leave with us. If drywall, cabinets or flooring got wet before the heater was replaced, ask us to look at where the water went, because moisture can travel farther than it appears.
If the heater is showing rust at the base, rumbling, or water in the pan, replacing it on your schedule is easier than an emergency. Send a photo of the label and of the space around it, and tell us whether you want the same type or are curious about tankless or heat pump. Our water heater page covers repair versus replacement, and you can book a visit online. Ask Du-All about any current offer and the eligible units and terms.
Our Palm City office is just across the St. Lucie River, so Stuart is close to home for our crews. We cover the downtown area, the streets around SE Stypmann Boulevard and SE Ocean Boulevard, and homes out toward Indian RiverSide Park on SE Monterey Road.

Before you call
Inside city limits, Stuart lists water heater replacement as an emergency repair that may proceed without prior approval, with the permit application filed the next business day. Unincorporated addresses follow Martin County rules.
Check your property tax bill or the Martin County property appraiser record. A Stuart mailing address alone does not mean you are inside city limits.
In unincorporated Martin County, the County checklist requires electrical load calculations for tankless electric water heaters. Any jurisdiction will expect the service to support the load.
Stuart allows a homesteaded owner to apply for their own water heater permit, but gas, electrical and relief valve work carry real hazards. We recommend a licensed plumber.
We serve 34994, 34996 and 34997, inside the city and in surrounding unincorporated Martin County.
