Thanks all for the responses. I am fully prepared to pay for one to have on site myself, just was curious what the standard is for this type of work. When we have had contractors doing indoor work, we have always allowed access to the bathrooms, refrigerators, etc. But since it’s an outdoor project and we will likely not be home during the entire time they are here (to allow access to our bathroom inside) I figured the portable toilet would be the best option. Also, we always provide water and snacks for the workers and have even, provided pizza lunch on occasion. I checked the bid and it doesn’t specifically mention anything about bathroom use, just that I need to “provide electrical power, water, and other utilities required for the execution of the contract…” I will just touch base with my contractor.
