Key points
- A certificate of insurance is a summary showing which policies a company carries and for what period.
- Additional insured status extends a company's coverage to named parties such as the landlord.
- Building management sets the insurance wording; get its requirements before you hire.
- NYC towers often require badges, vendor lists and freight elevator bookings for night crews.
- Suburban buildings focus more on keys, alarm codes and who locks up.
A certificate of insurance, often called a COI, is a one-page document that summarizes the insurance policies a cleaning company carries, the policy dates and the insurer. Building management usually requires one before a crew may work after hours, and often asks to be named as an additional insured. Alongside that, buildings set their own access rules for night crews, which can be strict in New York City towers and simpler in suburban offices.
What a certificate of insurance shows
A COI lists each type of coverage, such as general liability and workers' compensation, along with policy numbers, effective and expiration dates, and the insurer for each. It is issued by the company's insurance agent or broker, not typed up by the company itself. It is a summary, not the policy, so it shows that coverage exists but not every term. If you need to understand exclusions or details, ask your attorney or insurance advisor to review the requirements.
Check the dates on any certificate you receive. A COI that expired last month does not show current coverage. Many property managers keep a calendar of vendor expiration dates and ask for an updated certificate before the old one lapses.
What additional insured means
Being named as an additional insured means a party other than the policyholder, usually the landlord, the managing agent or the tenant, gains certain protection under the cleaning company's policy for claims arising from that company's work. Buildings ask for it because a crew working at night in shared areas could damage property or cause an injury, and the owner wants that risk sitting with the vendor's insurance first.
The exact wording matters. Building managers usually supply a list of entities to name, sometimes including an ownership company with a different name from the building itself. Send that list to the cleaning company before the start date so the certificate is issued correctly the first time.
Why building management controls this
In a multi-tenant building, management is responsible for common areas, elevators and the security of every floor. A vendor with access after hours affects all tenants, not just the one who hired it. That is why management, not the tenant, often sets the insurance requirements and approves vendors. A tenant who signs with a cleaning company before checking those requirements can end up with a crew that is not allowed through the door.
After-hours access in New York City towers
Large Manhattan buildings commonly treat cleaning crews the same way they treat any vendor. Expect some combination of the following: the company must be on an approved vendor list with a current certificate; crew members check in at the security desk with identification or receive temporary badges; names may need to be submitted in advance; and work happens within set hours. Equipment and supplies often have to travel by freight elevator, which may need to be booked and may close at a fixed time. Trash and recycling usually go to a specific location by a specific route. Some buildings also run their own cleaning of common areas, so the tenant's crew works only inside the suite.
Ask the property manager for the building's vendor rules in writing and share them with the cleaning company during the walkthrough.
Suburban equivalents on Long Island and in New Jersey
Office parks and standalone buildings outside the city usually have lighter formal rules but more responsibility placed on the crew. Landlords still frequently ask for a COI, sometimes with additional insured wording. Access tends to rely on keys, key cards or door codes rather than a staffed lobby. Alarm systems are common, so the crew needs its own code and clear instructions for arming the system when leaving. Parking, exterior lighting and which door to use at night are practical questions worth settling up front.
Getting it right before the first night
Collect the building's requirements, pass them to the cleaning company, and confirm the certificate and access arrangements are in place before the start date. A1 Commercial Cleaning is insured in every area it serves, including New York City, Long Island and New Jersey.
