The maintenance and repairs clause assigns responsibility for keeping the building and its systems in working order, from dock doors and lighting to HVAC, the roof and the structure. In most industrial leases the tenant handles nearly all maintenance and many repairs, while replacement of major systems is shared through a formula, so the details decide what you actually spend.
What this clause does
Industrial leases are generally net leases, which means you are expected to care for the property as if you owned it. At a minimum, plan to handle interior maintenance yourself: HVAC service, roll-up and personnel doors, dock levelers and bumpers, lighting, plumbing fixtures, windows and ceiling tiles. Many single-tenant leases add the exterior as well, including parking, landscaping and roof maintenance.
It helps to separate three ideas the lease often blends together. Maintenance is routine service. Repair is fixing something that broke. Replacement is installing a new component when repair no longer makes economic sense. Each can carry a different rule.
Many forms also require you to hold service contracts with qualified vendors for HVAC, fire sprinklers and alarms, the roof and landscaping, or they let the landlord hire the vendors and bill you. Institutional owners commonly service the HVAC themselves and bill quarterly because they want control over work that protects the asset. If you fall behind, the landlord can usually step in, do the work and charge you the cost plus an administrative fee.
Building type shapes the split. In multi-tenant parks, the landlord usually maintains the exterior and common areas and passes the cost through operating expenses, because pooling keeps the park consistent. In single-tenant buildings the division is more negotiable. Either way, build a short lease abstract that lists who handles the roof, HVAC, plumbing, dock equipment, fire systems and paving. When something fails at six in the morning, your facility manager should know whom to call without reading sixty pages.
Replacement is where the money is
HVAC is the usual flash point. A widely used trigger says a unit gets replaced when the repair would cost more than half of a new one, a rule both sides generally accept. Under many forms the landlord buys the new unit and you reimburse a share of it monthly, based on how much of the unit's useful life, often treated as twelve years, falls within your lease.
The math depends on one word. Some leases measure your share using the full lease term; others use only the time remaining when the unit is replaced. Say you have a six-year lease and a unit is replaced halfway through. Measured on the full term, you owe half the cost. Measured on the remaining term, you owe a quarter. Across a roof full of units, that difference is real money.
Ask a fairness question too. If an old unit has already outlived its accounting life, you should not end up paying toward a replacement while also having paid toward the original through prior operating expenses.
Roof, structure and the gray zone
The roof, load-bearing walls, foundation and HVAC are the capital items that draw the hardest negotiation. For much of the market's history the landlord kept roof structure and foundation, but there is steady pressure to shift more onto tenants because tenants control the building day to day. Not all triple net leases treat the roof the same, so read yours line by line. Skylights are the weakest point of a roof, trucks and trailer stands are hard on asphalt, and those costs show up at the end of the lease if nobody addressed them along the way.
Also check the delivery warranty. Many forms give you only a short window after possession to report systems that are not working, sometimes longer for HVAC, and some landlords try to eliminate it. On the right deal, a longer warranty is negotiable.
How to protect yourself
Inspect before you sign: roof age and condition, when skylights were last replaced, HVAC age and tonnage, dock equipment and paving. Have the landlord fix deferred maintenance before delivery and keep that separate from your improvement allowance, since deferred maintenance benefits the owner. Then negotiate the replacement formula, a remaining-term calculation, landlord responsibility for roof and structural replacement, and a meaningful warranty period. Keep every service record and invoice in one place; you will need them at move-out, and they help if a warranty or insurance claim comes up. Have a real estate attorney review the final language.
If you are the tenant
- Get the age and condition of the roof, skylights and every HVAC unit before signing, and ask the landlord to cure deferred maintenance at delivery.
- Negotiate HVAC and other capital replacements so your share is based on the time remaining in your term, not the full term.
- Ask the landlord to keep responsibility for roof replacement, structure and foundation.
- Push for a longer warranty on building systems, especially HVAC, than the form provides.
- Keep service contracts and records current throughout the term; they protect your deposit at move-out.
If you are the owner
- Decide whether you want to be a hands-on operator or push maintenance to tenants, and draft the clause to match how you will actually manage.
- Spell out who performs, who pays and how amortization works for each major system so there is no argument when a unit fails.
- Consider controlling roof and HVAC vendors yourself to protect warranties and asset value, and bill the cost back.
- Require tenants to provide maintenance records periodically, not just at move-out.

The replacement of building systems should be structured as an equitable sharing of expenses, not a way for someone to make a profit.
Common questions
Who replaces the HVAC in an industrial lease?
It varies. A common arrangement has the landlord replace a unit once repair would cost more than half of replacement, with the tenant reimbursing a share based on the unit's useful life that falls within the lease. Negotiate whether that share uses the full term or only the time remaining.
Is the landlord responsible for the roof in a triple net lease?
Not necessarily. Many industrial leases have the tenant maintain the roof and the landlord handle structural replacement, but there is no uniform standard and the trend has been toward shifting more onto tenants. Read the clause closely and negotiate before signing.
What maintenance should I budget for in a warehouse lease?
At a minimum, HVAC service, doors, dock equipment, lighting, plumbing fixtures and general upkeep of the interior. Depending on the lease, add landscaping, paving, fire system inspections and roof maintenance. Ask for three years of operating expense history to see what the landlord has been passing through.
