Quick answer
No. For water heater installation in Lake Worth Beach, Du-All Plumbing pulls the permit the city requires. The city's House Bill 803 notice says any plumbing, electrical or gas work still requires a permit regardless of project cost, and the under-$7,500 exemption excludes that work. Call 561-623-3111.
Water heater installation in Lake Worth Beach, 33460 and 33461, close to Du-All's own office on South E Coast Street, for bungalows in College Park and the Lucerne districts, homes in Mango Groves and Parrot Cove, and beyond.
Starting July 2026, Florida House Bill 803 allows some small residential projects under $7,500 to skip a building permit. Lake Worth Beach published a one-page notice explaining it, and it is clear about where water heaters land.
A water heater replacement connects to plumbing and to either electrical or gas service, so it sits on the permit side of that notice.
Lake Worth Beach is one of the few cities in the county that operates its own electric utility, alongside water, sewer and stormwater service, according to a county Inspector General audit of its utilities. If you are considering an electric tankless unit, which Department of Energy guidance says can draw 50 amps or more for whole-house models, or any change that increases electrical load, the panel and service size have to be evaluated first. When a service upgrade is involved, it means coordination with the city utility as well as an electrical permit.
For many homes, a like-for-like electric tank or a heat pump water heater changes the electrical picture far less than whole-house electric tankless does. A heat pump unit still has its own circuit requirements, so the installer checks the manufacturer's specifications against the existing circuit before recommending one.
The city lists historic districts including College Park, Old Lucerne, Northeast Lucerne, Southeast Lucerne and South Palm Park, the roughly 60-block district near Bryant Park and the Intracoastal. Inside a house, a water heater swap rarely touches anything historic reviewers care about. Outside is a different matter. A wall-mounted tankless unit, new vent terminations on a street-facing wall or an exterior heat pump installation could raise questions, and the city's notice specifically reminds owners that historic preservation approval can apply even to small projects.
Homes in these districts include older, compact houses, with heaters in small closets or added utility spaces. Older supply valves, undersized pans and relief valve lines that end in the wrong place are common findings in houses of any age that have been remodeled several times, so we inspect before quoting.
For a tank, the first-hour rating on the manufacturer's specification tells you how much hot water the unit can deliver in an hour starting full, measured under federal test procedures. Compare that to your busiest hour: back-to-back showers, a load of laundry and the dishwasher. For tankless, the key figure is the flow rate the unit can supply at your required temperature rise, read from the manufacturer's chart. ENERGY STAR suggests adding up fixtures that run at the same time to estimate peak demand.
In smaller bungalows, a modest tank with a strong first-hour rating is often enough. Larger homes in neighborhoods such as Mango Groves, Parrot Cove, Royal Poinciana or Tropical Ridge may have more bathrooms and more simultaneous use, which pushes toward a larger tank, a heat pump model with adequate recovery, or a properly sized tankless unit.
Du-All offer
Any new hot water or tankless heater
Ask Du-All to confirm eligible units, parts and labor coverage, and warranty terms.
Not valid with other offers. Not valid on prior service. Limit one coupon per service call.
Keep away from water near outlets or the heater's wiring, and do not stand in water to reach a switch or breaker. Close the cold supply valve if it is dry and within easy reach. For gas heaters, leave and call the gas utility or 911 from outside if you smell gas. Never plug or adjust the temperature and pressure relief valve; if it is discharging, a licensed plumber needs to find out why. A leak from a fitting can sometimes be repaired, while water seeping from the tank body usually means replacement, and only an inspection tells them apart.
Our leak detection and repair service can trace water that appears without an obvious source.
The city's Building Division handles building permits, plan review and inspections from 1900 2nd Avenue North, in the 33461 ZIP, and is open weekdays from 8 am to 4 pm. Your installer files there and schedules the inspection after the work is done. Because Du-All's Lake Worth Beach office is on South E Coast Street in 33460, this is home territory for our crews, though we still confirm the current filing requirements with the city for every job.
On replacement day, the old heater is drained and removed, the new one is set with its pan and drain where required, and supply lines, relief valve discharge and expansion control are completed. The tank is filled before power or gas is restored. FPL notes heaters often ship at 140°F while about 120°F serves most households, so ask the technician to set it at startup.
Send the heater's data plate photo, tell us its location and whether the house is in a historic district. Our water heater page explains the trade-offs between tank and tankless options. Request service or call 561-623-3111, and ask which units qualify for Du-All's current water heater offer and what coverage terms apply.
It depends on where the heater lives. Heat pump water heaters draw heat from surrounding air, so each model's manual sets a minimum air space, an operating temperature range and a condensate drain requirement. In a compact bungalow where the heater is in a small interior closet, those conditions are often hard to meet without louvered doors, ducting allowed by the manufacturer or relocation. A detached garage or a larger utility room is a more natural home. Relocation adds water lines, wiring and drainage to the scope, and in a historic district it may also bring an exterior review if anything changes on the outside of the house.
When the closet stays, a standard electric tank with a good first-hour rating is usually the practical choice. We show you the trade-off with the actual model's requirements in hand.
Frequently. Electric elements, thermostats and valves can be replaced on a sound tank, and rumbling often comes from sediment. Rusty water may start in old galvanized piping instead of the heater. A tank leaking through its shell, however, cannot be repaired, and replacement is the honest answer.

Before you call
The city renamed itself Lake Worth Beach in 2019. Some nearby unincorporated addresses still use a Lake Worth mailing address but are permitted by Palm Beach County, not the city.
The city's notice says plumbing, electrical and gas work always requires a permit regardless of cost, so a water heater replacement is not exempt.
An interior like-for-like swap rarely involves historic review, but exterior equipment or new wall penetrations in a historic district may. The city notes historic preservation approval can apply to small projects.
If a whole-house electric tankless unit requires a service upgrade, that involves the city utility and an electrical permit. A panel evaluation comes first.
With the city Building Division at 1900 2nd Avenue North, open weekdays 8 am to 4 pm.
