Terms to settle before the first delivery
Settle the term, the servicing schedule, what happens when a unit is damaged, how relocation works and how the rental ends. A written quote that names each item is better than a verbal promise. Ask the provider what notice it needs to add, move or remove units, and what it can do when units are free.
A long job tests the arrangement. Crews grow, plans change and weather gets in the way. A provider that is told early can plan; a provider that finds out late may only be able to offer what it has free that week.
Ask what the provider does if a service visit is missed because the site is blocked, and who is responsible for clearing the approach. Agree a contact on each side.
How often should long-term units be serviced?
It depends on the users and the weather. The Department of Public Health's portable toilet permit page says a portable chemical toilet in a residential area must be serviced at least every 48 hours, and the organizer confirms requirements with the city. Elsewhere, agree a schedule with the provider that fits your crew and season.
That 48-hour figure comes from the city's page for portable chemical toilets and applies to the situation it describes; do not assume it fits every site, and do not assume it does not. Ask the city or the provider which rule applies to yours.
For a long-term site, the practical question is what the crew actually needs. A large crew on a hot week can fill units faster than a schedule built in spring expects, so ask the provider how to adjust.
Winter and summer on a standing rental
Units that stay all year face both extremes. Philadelphia's July average high is 86 F and January's is 41 F with a low of 27 F. Heat means more visits and shaded placement; freezing weather means a winter additive and a cleared approach. Tell the provider when you expect each change.
June 2025 reached 100 F at the airport, the first time since 2012, and July 25, 2025 brought an Extreme Heat Warning with a high of 97 F. Annual snowfall runs roughly 20 to 35 inches, and a January 25, 2026 storm brought up to 9.5 inches.
On a standing site, keep the approach clear. A buried or iced-over unit cannot be serviced, and a unit left on a slope or in a low spot can be a problem after heavy rain.
Units that move as the work moves
Long jobs move. A crane relocates, a lot is paved, a phase finishes. Moving a unit is the provider's work, not yours. Give notice, say where the unit should go and ask what it can do when units are free. Do not tip, drag or empty a unit yourself.
A phased development such as Cherry Hill's Plaza Grande, the final phase of a billion-dollar redevelopment of the Garden State Park site, shows how a site's footprint changes. Units placed in the first phase may be in the way of the last.
Review the layout at each phase and ask the provider for a plan that fits the new footprint. For narrow city streets, see rowhouse renovation toilets for access questions.
