A cleaning crew with a key to your law office at 9 p.m. has unsupervised access to every open file, printer tray, and unlocked cabinet in the building, and Oklahoma Rule 1.6(c) makes the firm responsible for what happens next. That is the real problem behind how to choose a cleaning company for a law firm. The question is not whether the vendor can vacuum a conference room. It is whether the people who walk your halls after the last attorney leaves have been screened, instructed, and scheduled in a way the firm can defend. This guide lays out the vetting criteria office managers and managing partners in Tulsa, Oklahoma should require before handing over a key.
Why a Law Firm Cannot Vet a Cleaning Company Like Any Other Office
Most businesses hire a janitorial vendor on price, references, and a walkthrough. A law firm has a fourth factor that the others do not: a professional duty that follows every piece of paper in the building. Under Oklahoma’s version of Rule 1.6(c), adopted in 2016, a lawyer shall make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client. Nothing in that sentence limits the duty to attorneys and paralegals. It covers the deposition transcript on a desk, the settlement draft in a printer tray, and the intake form in an open recycling bin.
The duty also reaches the people the firm brings in from outside. The Oklahoma Bar Journal explained in 2018 that attorneys are responsible for the actions of all employees and must give nonlawyers appropriate instruction and supervision on confidentiality. A cleaning contractor is not an employee, but the logic is the same: if someone the firm chose has access to client information, the firm has to be able to show it made a reasonable choice and set reasonable terms.
That is why this decision belongs to a managing partner or office manager who understands the ethics rules, not only to whoever handles building maintenance. The vendor you pick becomes part of the firm’s answer to the question “what reasonable efforts did you make?”
How to Choose a Cleaning Company for a Law Firm: Seven Vetting Criteria
The table below lists seven requirements a Tulsa law firm should put in front of any cleaning company before signing. Each one maps to a specific way client information can leak, and each one has something concrete you can ask for.
| Requirement | Why it matters for a law firm | What to ask for |
|---|---|---|
| Background checks | Unsupervised after-hours access to client files | Written confirmation that every person assigned to your building is background-checked |
| Confidentiality agreement | Puts the duty not to read, copy, or discuss what is seen in writing | A signed agreement at the company level, and the option to require one from each worker |
| Document handling rules | Paper on desks, in printers, and in shred bins is client information | A stated rule that paper is not moved, read, or discarded and shred bins stay sealed |
| After-hours access control | Keys and alarm codes are the firm’s perimeter | A fixed schedule, a named list of who holds keys, and a process for returning them |
| Insurance | Damage or loss inside the office should not fall on the firm | A current certificate of insurance naming the firm |
| References from professional offices | Cleaning a warehouse and cleaning a bank are different jobs | Contacts at financial offices, medical offices, or other law firms |
| Scope by area | Some rooms should never be entered at all | A written scope listing restricted areas, off-limits offices, and the file room |
Read down the third column and you have a checklist for your first phone call with any vendor.
Background checks come first because the risk is unsupervised after-hours access to client files. Ask for written confirmation that every person assigned to your building is background-checked, not a general statement that the company “screens employees.” A confidentiality agreement puts the duty not to read, copy, or discuss what is seen in writing. Ask for a signed agreement at the company level, and the option to require one from each worker who enters the office. Our earlier post on whether cleaning companies sign confidentiality agreements covers what those documents usually contain.
Document handling rules matter because paper on desks, in printers, and in shred bins is client information. Ask for a stated rule that paper is not moved, read, or discarded and that shred bins stay sealed. After-hours access control matters because keys and alarm codes are the firm’s perimeter. Ask for a fixed schedule, a named list of who holds keys, and a process for returning them when staffing changes. Insurance matters because damage or loss inside the office should not fall on the firm, so ask for a current certificate of insurance naming the firm.
References from professional offices matter because cleaning a warehouse and cleaning a bank are different jobs. Ask for contacts at financial offices, medical offices, or other law firms. Finally, scope by area matters because some rooms should never be entered at all. Ask for a written scope listing restricted areas, off-limits offices, and the file room.
Document Handling: What Should Happen to Paper Left on Desks
Attorneys leave paper out. Trial prep, closing binders, and marked-up drafts do not go back in a drawer every night, and a cleaning policy that assumes a clean desk will fail on the first busy week. The practical answer is a two-sided rule: the firm reduces what is exposed, and the vendor commits to leaving what remains untouched.
On the firm’s side, FTC guidance for businesses that hold personal information recommends storing paper files in a locked room or locked cabinet, requiring employees to put files away and lock cabinets and office doors at the end of the day, and shredding, burning, or pulverizing paper before discarding it. The same guide advises investigating an outsourced company’s data security practices before hiring. That advice was written for consumer data, but it describes exactly the discipline a law office needs, and it gives the office manager a written standard to point to when asking attorneys to lock up.
On the vendor’s side, the rule should be simple enough that a new worker can follow it on night one. Paper on desks is not moved, stacked, or read. Printer and copier trays are left alone. Shred bins are emptied only by the shredding service, so the cleaning crew leaves them sealed. Trash is trash only if it is in a trash can. A vendor that already cleans banks and credit unions under confidentiality protocols will recognize this list immediately, and a vendor that hesitates is telling you something.
After-Hours Access, Keys, and Alarm Codes
Most law office cleaning happens after 6 p.m., which means the crew is alone with the building. Comment 3 to Rule 5.3 says that when a lawyer uses nonlawyers outside the firm, the lawyer should consider the education, experience, and reputation of the nonlawyer, the nature of the services involved, and the terms of any arrangements concerning the protection of client information. Janitorial work is not named in that comment, but the same due-diligence logic applies to anyone the firm lets in after hours.
In practice, access control comes down to a few habits the vendor should already have. The schedule is fixed and consistent, so the firm knows which nights and roughly which hours the crew is present. The firm knows by name who holds a key or alarm code, and that list is updated when a worker leaves. Keys are returned, not passed along. The alarm code assigned to the cleaning company is its own code, so the firm’s system logs who disarmed the building and when. Restricted areas, such as the file room, the managing partner’s office, or a room holding evidence for an active matter, are identified in the written scope and either locked or marked as off-limits.

Questions to Ask Before You Sign
The ethics rules do not require perfection; they require reasonable efforts. Formal Opinion 477 from the American Bar Association describes the factors behind that standard: the sensitivity of the information, the likelihood of disclosure without added safeguards, the cost of the safeguards, and the difficulty of implementing them. Applied to a cleaning contract, those factors argue for a short list of direct questions rather than a long procurement process. Ask each vendor the following, and write down the answers.
- Is every person who will enter our building background-checked, and will you confirm that in writing? A vendor that cleans financial offices should be able to say yes without hesitation.
- Will you sign a confidentiality agreement, and can we require one from each worker assigned to the firm? The company-level agreement is standard; the per-worker version is something the firm can request.
- What is your rule for paper on desks, printer trays, and shred bins? The right answer is that none of it is touched.
- Who will hold our keys and alarm code, and what happens when that person leaves your company? You want a named list and a return process.
- Can you give us references from professional offices, and will you provide a certificate of insurance naming the firm? Both should arrive before the first visit.
A vendor that answers all five clearly is a vendor whose practices you can describe to a client, a partner, or a bar investigator if you are ever asked to.
Why Choose Premier Janitorial for Law Firm Cleaning in Tulsa
Confidentiality handling is the reason a Tulsa law firm should look at how a cleaning company treats its financial clients before anything else. Premier Janitorial cleans banks and credit unions with background-checked staff, confidentiality protocols, and secure-area maintenance, and the same approach carries directly into a law office. Paper on desks is not moved or read. Shred bins are left sealed for the shredding service. After-hours access is scheduled and consistent, so the firm knows when the crew is in the building. Before service starts, the Free Facility Assessment walkthrough identifies restricted areas, such as the file room or offices tied to active matters, so those rooms are written into the scope as off-limits rather than discovered by accident later.
For firms that want the confidentiality agreement in writing, that is something the firm can request as part of the arrangement. Premier Janitorial is family-owned and based in Tulsa, Oklahoma, and it serves law offices in Broken Arrow, Bixby, Jenks, Owasso, and Sand Springs on the same terms.
Conclusion
How to choose a cleaning company for a law firm comes down to one question: can the firm explain, in plain terms, why it was reasonable to give this vendor a key? Background checks, a confidentiality agreement, document handling rules, after-hours access control, insurance, references from professional offices, and a written scope by area are the pieces of that explanation. Put them in the contract before the first night of service, and the crew that walks your halls at 9 p.m. becomes part of the firm’s reasonable efforts rather than a gap in them. Tulsa law firms that treat the cleaning contract as a confidentiality decision rather than a maintenance decision will find the vetting process short, because the right vendors already expect these questions.

Frequently Asked Questions
Do cleaning staff sign non-disclosure agreements?
Many commercial cleaning companies will sign a confidentiality or non-disclosure agreement at the company level, and some will have individual workers sign one as well. A law firm can and should request both. Ask for the signed document before the first visit.
What is the protocol for documents left on desks?
The standard rule for professional offices is that cleaning staff do not move, stack, read, or discard any paper on a desk, in a printer tray, or in a shred bin. Trash is emptied only from trash cans. Attorneys should still lock up sensitive files at the end of the day.
Are cleaners background-checked for criminal history?
Reputable companies that serve banks, medical offices, and law firms typically run background checks on staff before assigning them to a client site. Do not assume this; ask for written confirmation that every person entering your building has been checked.
How do cleaners handle keys and alarm codes for after-hours access?
A well-run vendor assigns keys and codes to named individuals, keeps a list of who holds them, and collects keys when a worker leaves. The cleaning company should have its own alarm code so the firm’s system records who entered and when.
What is the difference between law office cleaning and general office cleaning?
The physical tasks are largely the same: floors, restrooms, kitchens, conference rooms, and trash. The difference is in the rules around access and paper. Law office cleaning adds background-checked staff, confidentiality agreements, strict document handling, controlled keys and codes, and a written scope that keeps certain rooms off-limits.
