What makes a monthly rental rate go up in 2026?

Inflation and labor costs are the main drivers, but your heavy use and waste disposal fees also push up the monthly rental rate for 2026. A crew of 150 on a construction site requires more units and service frequency under OSHA 1926.51, which mandates four toilets and four urinals or their equivalent for that size crew. Your weekly service is standard, but heavy use means the holding tank fills faster, requiring more frequent pumping or larger units to avoid complaints. Waste disposal fees at treatment plants rise annually due to regulatory costs and fuel surcharges. Formaldehyde-free deodorizer costs more than older formulas but is often required by wastewater facilities. Your good truck access helps control costs, but long-term contracts still reflect broader economic pressures like insurance, equipment maintenance, and rising wages for drivers.
