Documented key control
Keys and fobs are logged, secured, and audited. Access is limited to the assigned team for your building.
Single-tenant & multi-tenant properties
Your lobby is the first thing every tenant, client, and prospect judges. We keep office buildings across Columbus & Central Ohio at a Class A standard — after hours, under strict key control, with inspections you can show your tenants.
Building-wide scope
Consistency is cumulative: from the curb to the top floor, one neglected elevator cab undoes a spotless lobby.
Security & access
Letting a vendor into your building at night is a trust decision. We treat it that way.
Keys and fobs are logged, secured, and audited. Access is limited to the assigned team for your building.
The same trained, background-checked team services your building every visit — no rotating strangers.
Written open/close procedures per building — alarms armed, doors checked, lights per your spec.
Certificates of insurance naming your ownership entity and management company, delivered before service starts.
For property managers
If you manage a portfolio, your janitorial vendor should reduce your workload — not add a property's worth of follow-up. 3Z's consolidates scopes, invoicing, and inspection reporting across your buildings, with one account manager who knows all of them.
Common questions
Yes — that's the standard model. Crews work after business hours on a schedule set per building, and day porters handle anything that can't wait until night. Tenants see the results, not the process.
All three. We contract building-wide with owners and management companies, and per-suite with individual tenants. When both exist in one building, we keep the scopes and invoicing cleanly separated.
Every complaint goes to your account manager, gets logged, and is corrected within 24 hours. You receive confirmation when it's resolved — so you can close the loop with your tenant the same day.
Yes. Send us the cleaning specifications from your leases and we'll build the scope of work to match them line for line, so your janitorial program supports your lease obligations instead of contradicting them.
