The papers a property manager asks for before you can clean their building
The step between cleaning houses and cleaning buildings is not equipment or staff. It is three documents — and the business that can produce them in a day wins bids from businesses that cannot.
The short answer
A property manager will ask for three things before letting you into a building: a certificate of insurance showing general liability, a bond, and proof your L&I account is current if you have employees. Missing any one of them usually means the contract goes to someone else.
The certificate is the document that does the work. It is a one-page summary from your carrier showing your limits and dates, and it will normally have to name the building owner or manager as an additional insured. It proves coverage exists; it does not create any.
Only two of the three come from an insurance agency. In Washington, workers' compensation is bought from the Department of Labor & Industries and nowhere else, so nobody can sell you that part — but your account being current is still something the building will check.

Why buildings are worth the paperwork
Because commercial work is recurring and scheduled, while residential work is episodic and price-shopped. An office cleaned four nights a week is a contract, not a series of jobs. The paperwork is the barrier to entry, and a barrier to entry is exactly what protects your margin once you are through it.
The reframe that matters
Insurance in this trade is not a cost of protection. It is the key to a class of customer you cannot quote today. That is a different purchase decision, and it is the reason to buy coverage before someone demands it rather than after you have lost a bid over it.
The three documents
They prove three different things to three different worries: that you can pay for damage you cause, that the building is protected if something goes missing, and that an injury to your worker will not become the building's problem. Different documents, different issuers.
| Document | What it proves | Where it comes from |
|---|---|---|
| Certificate of insurance (general liability) | You can answer for damage and injuries caused by your work | Your insurance agency, from your policy |
| Janitorial or surety bond | The building is made whole if an employee steals | A surety, arranged through an agency |
| L&I account in good standing | Your employees' injuries are covered by the state fund | Washington L&I — no agency sells this |
If you have no employees
The third document changes shape. L&I coverage is mandatory once you have workers, so a genuinely solo operator has a different conversation with the building — and should have it openly, because a manager discovering later that there is no L&I account is a manager who terminates the contract.

What a certificate actually says
Less than people think, which is why reading one is quick. It names you, names your carrier, lists the policy number, shows the effective and expiration dates, and states the limits. Below that sits a box for the certificate holder and the additional insured wording.
The limits a building will specify
Commercial cleaning contracts commonly name a per-occurrence limit and a higher aggregate. The number is set by the building's own risk policy, not by your size, so a small cleaning company bidding on a large building will be asked for the same limit as a large one.
Read the expiration date before you file it away
A certificate is a snapshot of a policy on the day it was issued. Most commercial contracts allow the building to suspend you the moment it lapses. Put the date in your calendar with a month of warning, because nobody at the building will remind you kindly.
Additional insured, explained
The building owner or manager wants your liability policy to respond for them too, for claims arising out of your work. That is a normal request in commercial cleaning and usually reasonable: they are being pulled into a claim caused by your operations, not by theirs.
What is worth reading in the wording
How far it reaches. Some additional insured forms cover claims arising from your work specifically; broader versions can extend to the building's own negligence. That is a question to ask before signing, and a good reason to have an agency read the paragraph rather than forwarding it unread.
What a certificate does not prove
That you are covered for the thing most likely to happen. A certificate lists limits, not exclusions — so it looks identical whether or not your policy covers damage to the property in your care. Exclusion j.4 of the standard liability form removes exactly that, and no certificate will mention it.
Why that matters on a building contract specifically
Because the objects in an office are expensive and portable: monitors, laptops, conference room screens, art. A policy that satisfies the building's certificate requirement and still excludes the client's movable property is a policy that will pass inspection and fail at the claim. Here is how that exclusion works.
Getting ready before you bid
The whole point is to have the documents before someone asks, because the asking happens late and the answer is expected in days. Four things, in this order, and none of them require you to already have the contract in hand.
- Get the general liability policy in place, at a limit that matches what buildings in your market ask for rather than the cheapest available.
- Confirm your business licence and UBI are current. Renewal is $5 a year and the UBI is what a manager looks up.
- Open or verify your L&I account if you have employees, and know your class — janitorial is 6602.
- Ask your agency how fast it issues certificates. If the answer is not "same day", that will cost you a bid eventually.
What we do on our side
We issue certificates from the policies we write, usually the same day, with the additional insured wording the building asked for. If you want to see what the underlying policy should look like first, start with what cleaning business insurance covers, or go straight to a quote.
The part we do not sell
L&I. We will still tell you what your class rate is and how the account works, because it is the question we get most and the answer costs us nothing — see the workers' compensation page. Everything else is on our business insurance page, and we are in Tacoma and Auburn.
Frequently asked questions
What is a certificate of insurance, exactly?
A one-page summary your carrier issues proving your policy exists, with the limits and the dates on it. It is not the policy and it grants no coverage — it is evidence. That is why a certificate can look perfect while the policy behind it has a gap.
How fast can I get a certificate of insurance?
From an agency that already has your policy, usually the same day and often within the hour. That speed is the whole point: a property manager asking for a certificate is a property manager close to signing, and the bid that answers first has an advantage.
What does 'additional insured' mean and should I agree to it?
It extends your liability policy to cover the building owner or manager for claims arising from your work. It is a standard ask in commercial cleaning and normally reasonable. What is worth reading is the wording — some versions reach further than the work you are actually doing.
Why does the manager want to be notified if my policy cancels?
Because a certificate is a snapshot and policies lapse. A notice-of-cancellation provision means the building learns before your coverage disappears rather than after an incident. Expect it in any contract worth having.
What happens if my certificate expires mid-contract?
In most commercial cleaning contracts the building can suspend or terminate you on the spot. Put the expiration date in your calendar with a month's warning — losing a contract to an administrative lapse is the most avoidable way to lose one.
Do I need a certificate for residential house cleaning?
Rarely required, increasingly asked for. Homeowners in managed communities and anyone hiring through a referral network are starting to ask, and being able to produce one in an hour is a quiet competitive advantage over whoever cannot.
