High-rise unit servicing when the building elevator is out.

The reliable plan is to negotiate a service credit for blocked access and consider moving the unit to a ground-floor location during elevator outages. A standard portable toilet with a 50 to 70 gallon holding tank for 50 workers on a five-day week needs service more often than the weekly norm to prevent overfilling. OSHA 29 CFR 1926.51 requires at least two toilet facilities for your crew size, but one unit can be sufficient if serviced frequently.

You should absolutely talk to the rental company about a credit for missed service visits. Most companies bill for the trip when their vacuum truck cannot reach the unit. Explain the recurring elevator downtime and ask for a policy adjustment, like not charging for a documented outage. Scheduling an extra service after a known downtime is a good proactive step, but it adds cost if the rental company does not offer a discount.

The best long-term solution may be to plan for a ground-level cluster when the elevator is scheduled for maintenance. This avoids the access problem entirely and keeps the units serviceable. A blocked unit is a health and compliance risk for your crew, so a clear access plan is essential.
