How much to rent a porta potty for a week? Is there a weekly rate between the event and monthly prices

Yes, rental companies do have a weekly rate for a standard portable toilet, and it falls between the higher weekend event rate and the lower monthly construction rate. A week-long rental for a crew is a common request. For three workers on a deck build, a single standard unit is sufficient; OSHA 1926.51 requires one toilet for 20 or fewer workers. The weekly rate will include delivery and one service visit, which is the standard service frequency for a week. Your setup is ideal: level grass with truck access right to the placement spot, so there should be no extra charges for difficult access. The price is driven by the unit type, the rental duration, and the included service. Since you don't need a flushing unit or a handwash station for a basic crew, the cost will be for the most basic serviceable unit. You are not being charged an event premium, and you are not getting the discount of a long-term monthly contract, so the weekly rate is the middle-ground price for that exact timeframe.

Ray is right about the weekly rate and the setup, but you should call the rental company to confirm the service schedule. A standard weekly rental usually includes one service visit after seven days, but with only three workers, you might not need it. The rental company determines the service frequency based on use. If the crew is light, the holding tank can last the whole week without a pump-out. The driver will check the unit's condition and paper supply during the drop-off and may skip the mid-week service if it is not full. This can affect the final bill, so ask if the service visit is mandatory or optional for your low-use situation.
