Four day reroof on an occupied house: do I need a porta potty?

Marcus B.asked 0 viewsRules, Permits & ADAOsha 1926 51Residential constructionHealth departmentResidentialStandard unit

I'm starting a four-day reroof on an occupied house next week. My crew has six people, working eight-hour days. The homeowner says we can use their bathroom inside, which is convenient, but I'm not sure if that meets OSHA requirements for construction sites. The job is residential, so no alcohol or food service, and the ground is a level lawn with truck access. I usually rent a standard portable toilet for my jobs, but I'm wondering if the homeowner's offer changes that. Does OSHA still require a dedicated unit on site, or is using the house bathroom sufficient?

For a six-person crew, OSHA still wants toilet access on site, but the homeowner bathroom can count if the crew can actually use it whenever they need it.

OSHA 1926.51 Table D-1 calls for one toilet seat when you have 20 or fewer employees. It does not say that toilet has to be a standard unit. A working bathroom inside the house meets the rule if workers can get to it during the shift without waiting on someone to unlock a door or asking permission each time.

I still drop a unit on most occupied reroofs. Muddy boots through a finished house turns into a complaint by day two, and if the owner changes their mind mid-job you suddenly have no toilet. A standard unit on the lawn keeps the crew outside and keeps the relationship clean. Level ground and truck access like you described make delivery easy.

So: house bath can satisfy OSHA if access is real and unrestricted. Renting a unit is still the safer job habit for a four-day roof with six guys.
