The fire marshal leaves a deficiency notice on the counter: the exhaust system is overdue, fix it within the correction window. The tenant calls the landlord, who says the lease makes the tenant responsible for the kitchen. The tenant reads the lease and finds nothing about hood cleaning at all. The correction clock keeps running while two parties argue over who owns the problem.
This is one of the most common — and most avoidable — disputes in commercial food-service real estate. The question of whether the landlord or tenant is responsible for hood cleaning has a clear default answer under fire code, but that default can be reassigned by a lease, and the lease is silent or ambiguous a surprising share of the time.
This post lays out the NFPA 96 default, why the lease so often fails to settle it, what to check in your own agreement, and the one step that ends the argument before the fire marshal shows up.
The NFPA 96 Default: The System Owner Is Responsible
NFPA 96, the national standard governing commercial kitchen exhaust systems, assigns responsibility to the owner of the system. The owner must ensure the exhaust system is inspected and cleaned at the required frequency and that records are kept.
Critically, the standard allows that responsibility to be transferred in writing — for example, to a tenant or operator through a lease, or to a management company through a service contract. Absent that written transfer, the default sits with ownership.
In practice, the answer depends almost entirely on what the lease says. If the lease transfers responsibility, the lease controls. If it is silent, the code default — the owner — is the fallback, and that gap is exactly what produces disputes.
Why This Question Comes Up So Often
Commercial leases are long and heavily negotiated, but exhaust-system maintenance frequently slips through. A lease may make the tenant responsible for "all kitchen equipment" without naming the hood, duct, or rooftop fan — leaving room to argue whether a fixed building exhaust system is the tenant's "equipment." Or it may say the landlord maintains "building systems" without clarifying whether grease exhaust counts as one.
So lease language is silent or unclear on hood cleaning a large share of the time. Nobody notices while the kitchen runs fine. The ambiguity only surfaces when a deficiency notice forces the question — and by then, both sides read the gray area in their own favor.
What to Check in Your Lease
Whether you are a tenant or a property manager, read the agreement now, not after the citation. Look specifically for:
- Any clause naming the exhaust system, hood, duct, or grease equipment directly — not just "kitchen equipment" in the abstract.
- The maintenance and repair section — who maintains "building systems" versus tenant "trade fixtures," and which bucket the exhaust falls into.
- NFPA 96 or fire-code compliance language — some leases assign code compliance to one party explicitly, which settles it.
- Any incorporated management contract or rules — in multi-tenant buildings, a separate property-management agreement may handle shared exhaust.
If the lease is silent: do not assume the code default protects you. Get the responsibility assigned in writing — a lease amendment, a side letter, or a documented service agreement naming who schedules and pays for cleaning. Written clarity is cheap; a correction-order dispute is not.
The Trap: Both Sides Assume the Other Handles It
The worst outcome is not a clear "it's yours" — it is a mutual assumption. The landlord assumes the operating tenant handles the kitchen they cook in. The tenant assumes the landlord maintains a fixed system bolted to the roof. Neither schedules a cleaning, and the grease builds for months.
Then the inspection comes, and the consequences fall on whoever the Authority Having Jurisdiction holds accountable — often the operating business on site, regardless of who "should" have paid. A deficiency notice can carry a tight correction window, repeat-violation escalation, and in a fire, an insurance claim that scrutinizes whether anyone maintained the system at all. "I thought they were handling it" is not a defense a fire marshal or insurer accepts.
DMV Strip Malls, Food Halls, and Multi-Tenant Setups
This problem is especially common across DC, Maryland, and Virginia, where so much restaurant space sits in strip malls, mixed-use ground floors, and food halls. Multi-tenant configurations multiply the ambiguity:
- Shared exhaust systems in food halls, where several stalls vent through common ducting and one fan — and no single tenant clearly owns the shared run.
- Strip-mall end caps where a restaurant's rooftop fan sits above a unit the tenant cannot easily access without landlord coordination.
- Second-generation spaces where the exhaust system was built by a prior tenant, leaving genuine confusion about whether it is a building asset or a trade fixture.
Property managers carry real exposure too: an unmaintained shared system is a building-wide fire risk, and a vacancy turning over with an out-of-spec hood becomes the landlord's problem at fit-out. Our guidance for property managers covers keeping multi-tenant exhaust compliant without becoming the de facto operator of every kitchen.
The Practical Takeaway: Confirm in Writing
You do not need to win the legal argument about who is technically responsible. You need the responsibility documented and the cleanings actually happening — before the next fire marshal visit, not after the deficiency notice.
The cleanest fix is a documented recurring maintenance plan that names who schedules, performs, and pays for cleaning, and produces the records both the lease and the AHJ require. Whether the bill sits with landlord or tenant, a written plan ends the ambiguity and keeps the system compliant.

Frequently Asked Questions
Is the landlord or tenant responsible for hood cleaning?
Under NFPA 96, the owner of the exhaust system is responsible by default, but that responsibility can be transferred in writing through a lease or management contract. In most restaurant leases the obligation is assigned to the operating tenant — but only if the lease actually says so. If the lease is silent, the code default falls back to ownership, which is where disputes begin.
What if my lease doesn't mention hood cleaning at all?
A silent lease is the most common source of disputes. Do not assume the other party is handling it. Get responsibility assigned in writing through a lease amendment, side letter, or documented service agreement that names who schedules and pays for cleaning, so there is no ambiguity when a fire marshal issues a deficiency notice.
Who gets fined if the hood isn't cleaned — landlord or tenant?
The Authority Having Jurisdiction typically holds the party operating the kitchen accountable for compliance, often regardless of who the lease says should pay. That is why a written maintenance arrangement matters: it determines who bears the cost, while the operating business usually bears the regulatory and fire risk on site.
Who is responsible for kitchen exhaust cleaning in a food hall?
Shared exhaust in food halls and multi-tenant buildings is the hardest case, because several tenants may vent through common ducting and a single fan that no one clearly owns. Responsibility should be spelled out in the lease or a separate property-management agreement; when it is not, a documented recurring plan covering the shared system is the practical way to keep it compliant.
The Bottom Line
NFPA 96 makes the system owner responsible unless the lease or a contract transfers that duty in writing — and because leases are so often silent, the safest position is documented clarity, not assumption. Read your lease for the exhaust system specifically, and if it is unclear, fix that on paper now.
