The vendor exhibit, not the lease
A cleaning company rarely signs a lease with a landlord; it signs a service agreement or building access agreement with a vendor insurance exhibit attached. The exhibit protects the owner from the claims that come with after-hours access: theft from tenants, slips on wet floors, damage to finishes, and an injured cleaner working alone. Each of those has a line in the exhibit.
The lines a landlord's vendor exhibit names
General liability with the owner and manager added covers injuries and damage to the building and tenants' property, with a damage-to-premises limit that office buildings often raise. The crime bond or third-party extension covers theft from tenants, which no other policy does. Workers' compensation with a waiver keeps a cleaner's injury from becoming the owner's claim. Auto covers staff moving between buildings. An umbrella sits above in larger properties.
How to check your policies against the exhibit
Match the general liability limits, confirm the additional insured, primary and waiver forms by number, and check the damage-to-premises limit. Confirm the crime policy carries the client property extension or that a janitorial bond is in force at the stated limit. Check the workers' compensation information page and the waiver endorsement. Review the auto dec page for the combined single limit and hired and non-owned coverage. Then confirm the umbrella schedule where required. Each gap is a request to the carrier.
Keep the certificate current
Building owners want a certificate before the first shift and at each renewal, with notice of cancellation. A live certificate link stays current across renewals and notifies the owner when a line changes, with the official PDF attached, which matters when you clean a dozen buildings.
