Where the requirement hides
Management companies use a standard vendor agreement with an insurance exhibit, applied across their portfolio, and institutional owners layer their own requirements on top. The strictest owner in the portfolio often sets the standard for every property the manager runs.
One vendor, many files
The manager's compliance team tracks certificates per property. The same landscaper, cleaner or electrician is asked for the same certificate, with a different owner entity named, for each building. Blanket additional insured and waiver forms make that possible; scheduled forms make it a monthly chore.
Seasonal vendors
Snow and ice is the requirement that catches landscapers: many landscaping liability policies exclude it, and managers verify it specifically before winter. Applicators of pesticides and herbicides are asked for pollution coverage on the same portfolios.
What to send the manager
A certificate naming the owner entity, the association and the management company as additional insured on general liability, with waiver of subrogation on liability and workers' compensation, auto, umbrella where required, crime for access vendors and snow and ice or pollution where the work calls for it. Share the live link into each property's file so renewals never generate a round of requests.
