Who’s Responsible for Plumbing Repairs in Commercial Properties?

In the world of commercial real estate, a leaky pipe or a backed-up sewer line is more than just a maintenance headache. Unlike residential rentals, where landlord responsibilities are largely dictated by clear-cut state laws, commercial leases are often complex, highly negotiated documents. When the water stops flowing in a Mechanicsburg retail strip or a Harrisburg office complex, the first question asked is: “Who is paying for this?”

The Lease Dictates the Responsibility

In most commercial agreements, responsibility for plumbing falls into three main categories:

1. The Triple Net (NNN) Lease: Common in standalone retail and industrial buildings, this lease typically places nearly all maintenance responsibilities—including the main sewer line, water heaters, and roofing—on the tenant.
2. The Gross Lease: Often found in multi-tenant office buildings, the landlord usually handles the “core and shell” of the building, including the main plumbing stacks, while the tenant handles the fixtures within their specific suite.
3. The Modified Gross Lease: This is where things get blurry. Responsibilities are split, and without specific language, a failed backflow preventer or a broken slab pipe can lead to weeks of finger-pointing.

Common “Grey Areas” in Commercial Plumbing

Even with a signed lease, certain issues fall into a grey area. At Bob Means Plumbing, we encourage our clients to clarify these four areas before an emergency occurs:

• The Main Sewer Line: If a tree root in the parking lot clogs the sewer line, but the backup occurs in the tenant’s bathroom, who pays? Generally, landlords are responsible for “common” lines, while tenants are responsible for “lateral” lines serving only their space.
• Backflow Prevention: These devices are required by Pennsylvania law to be tested annually. If the device serves the entire building, it’s usually the landlord’s cost. If it’s a specialized device for a tenant’s equipment (like a chemical mixer), the tenant often bears the cost.
• Water Heaters: If a tenant uses a standard amount of water (like an office), the landlord might supply it. If the tenant is a high-volume user (like a hair salon), the tenant usually owns and maintains the equipment.
• Grease Traps: In almost every restaurant scenario, the grease trap is the tenant’s responsibility. However, if a tenant fails to maintain it and damages the building’s main line, the landlord may have grounds for a costly back-charge.

Tips from Our Trusted Partners at D’Angelo Realty Group

• When faced with a planned or unplanned repair, consult your lease and keep your property manager in the loop. If the Landlord is responsible to make the repair, they will likely want to be in control of the contractor and scope of work.  
• Planning renovations? Make sure you have permission and understand your responsibilities to the property owner.
• Stay on top of preventative maintenance. Many leases make commercial tenants responsible for mechanical items in addition to surface finishes. Regardless of responsibilities, most leases will make preventative maintenance like filter replacement, the tenants responsibility. If the tenant is not responsible for the equipment but fails to complete their required maintenance, they could be facing a large and unexpected expense. Clean filters are inexpensive and also improve indoor air quality. Familiarize yourself with how to locate and change your filters to avoid an unexpected breakdown. Mechanical equipment rarely waits for an ideal time to break down.
