Plumbing for Storefronts and Kitchens on Lafayette Avenue
The two avenues are the borough's commercial corridor, and the borough's own offices sit at 445 Lafayette Avenue. This is a commercial corridor, not a residential subdivision, and its plumbing needs are different from a home's.
A restaurant sees grease in its drains. A salon or a bakery depends on steady hot water. An office mostly needs restrooms that work. Tell us what kind of space you run and we will plan the visit around it.
Tenant or Landlord: Who Should Call the Plumber?
Responsibility depends on your lease. We are not lawyers, but these questions help you decide quickly.
If you are the tenant
- Check your lease for who pays for repairs inside your space.
- Know where your own shutoff valve is.
- Tell the landlord when water is coming through a ceiling or wall.
- Photograph damage to stock and equipment.
If you are the landlord
- Find out whether a leak started in one unit or in the building's lines.
- Keep a record of which valves serve which tenants.
- Decide who can approve work after hours.
- Make sure every tenant has your contact number.
Common Commercial Plumbing Problems and the First Move
General guidance for small commercial spaces. It does not describe how often these happen on Lafayette Avenue.
| What you see | Likely cause | Do this first |
|---|---|---|
| Slow kitchen floor drain. | Grease or food buildup in the line. | Stop pouring grease and food waste into drains, then call. |
| Restroom toilet backing up. | Blockage in the branch or main line. | Close the restroom and stop flushing. |
| No hot water at the sink. | Failed heater element, burner or tank. | Shut the cold supply to the heater and call. |
| Stain spreading on a ceiling. | Leak from the unit above or a supply line. | Shut the valve you can reach and call. |
Greasy or repeated blockages are often a job for hydro jetting rather than a plain cable, and routine drain cleaning keeps small clogs from becoming closures. A heater that has quit is a water heater repair call.
Permits, Storms and the Borough Offices on Lafayette Avenue
The Hawthorne Building Department at 445 Lafayette Avenue issues plumbing permits under the New Jersey Uniform Construction Code. The borough lists its hours as weekday mornings and afternoons and says it issues no permits after 3 PM. Replacing a water heater with one of the same capacity counts as minor work, but you still notify the office and have it inspected.
The borough's environmental inventory records that Tropical Storm Henri flooded Lafayette Avenue between Warburton and Central on August 22, 2021. Ground-floor tenants can use that as a reason to know where floor drains, shutoffs and any sump pump are before the next storm.
Water or Sewage Inside the Business? Do This First
Protect people first, then stock and equipment.
- Keep customers and staff out of wet or flooded areas, and unplug equipment only if you can do it from a dry spot.
- Shut off the main water valve, or the valve that serves your space.
- If water is near outlets, panels or kitchen equipment, stay away and call 911 if you feel unsafe.
- Photograph the damage before you clean up, then call your landlord and us.
If you smell gas, leave the building, then call the gas utility or 911 from outside. A leaking hydrant or a main breaking in the street is a call to the Hawthorne Water Department.

Commercial Plumbing Questions for Lafayette Avenue
Yes, you can call about drains, restrooms, leaks and water heaters at a business. Tell us the type of space, what is happening and whether you own or lease. We will explain the next step before any work starts.
That depends on your lease, and a lawyer or your landlord can answer it. Practically, we can describe the cause and the work so you have something clear to send. Ask who must approve repairs before the plumber starts.
Many plumbing changes need a permit from the borough building department at 445 Lafayette Avenue. Simple repairs may not, and a same-capacity water heater replacement is treated as minor work that still needs notice and inspection. When in doubt, ask the office before work begins.
Keep grease and food solids out of the drains, scrape plates before washing, and clean strainers daily. If drains still slow down, schedule drain cleaning before they stop. Whether you also need a grease interceptor depends on your use and local rules, so ask your landlord and the borough.
