How many porta potties do I need for a construction site?
OSHA 1926.51(c)(1) sets the baseline: one toilet facility for every 20 workers or fewer, then one toilet seat and one urinal per 40 workers as headcount climbs. A 25-person crew needs one unit minimum. At 80 workers you're looking at two units with urinal capacity. The rule changes at 200 employees: you'll need one toilet seat and one urinal for every 50 workers. Most construction managers in the Boston area pair a standard portable toilet with weekly service calls rather than sizing up to a restroom trailer, but site conditions vary. If your crew rotates shifts, you might need more capacity than headcount alone suggests. Boston Porta Pros visits Cambridge sites weekly under the industry standard covered by ANSI/PSAI Z4.3, which assumes one service per week for up to 10 users over a standard 40-hour week.
What does delivery to Cambridge cost?
Delivery to Cambridge from Boston runs between 50 and 150 dollars per week, depending on frequency and unit type. A one-day emergency delivery carries a higher fee than a recurring weekly rental. Roll-off dumpsters, which require about 60 feet of straight clearance behind the truck, sometimes incur surcharges if your Cambridge address has tight alley access or street parking constraints. Request a quote with your exact address and we'll confirm truck access before charging. Storage containers and temporary fencing also deliver to Cambridge; fence rentals typically cost between 30 and 75 dollars per day. If you're managing a multi-phase project near Harvard Square or closer to the Charles River, staging multiple units across different locations within Cambridge may reduce per-unit delivery cost compared to a single large trailer.
Can I place a portable toilet in the right of way?
Placement in the public right of way in Cambridge needs confirming with the city before delivery. Boston Porta Pros cannot quote a guarantee here because municipal rules differ from Boston's own code. Many Cambridge projects position units on private property, construction sites, office parking lots, and event venues like the Cambridge Common do this routinely. If your site has no private space and you need street placement, contact the Cambridge permitting office directly and we'll coordinate once approval arrives. ADA accessible units meet ADA Standards section 213.2, requiring at least 5 percent of clustered single-user units (and never fewer than one) to be accessible; that specification holds everywhere we operate, including Cambridge. Standard units measure about 44 by 48 inches on the ground and stand 92 inches tall, so confirm your placement location has room before we arrive.
Why should I rent from Boston Porta Pros?
We operate across the Boston metro and deliver to Cambridge within 24 hours of booking. Our units handle everything from small renovation projects to large construction crews and outdoor events. A standard porta potty rental comes cleaned and restocked at each service visit. Deluxe flushable porta potties cost more but feel closer to a real bathroom, they're popular for events and office sites where appearance matters. We also rent roll-off dumpsters, septic pumping service, storage containers, handwashing stations, and temporary fence so you can coordinate everything through one company. Cambridge customers often combine a porta potty with a handwashing station; 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing facilities, not hand sanitizer alone. Most of our Cambridge rentals are weekly commitments, though we handle weekend and monthly terms too.
How often does my portable toilet get serviced?
Weekly under standard conditions. ANSI/PSAI Z4.3 baseline is one service per week for up to 10 users over 40 hours, which covers most small crews and events. Busier sites or events need twice-weekly or daily service. We schedule around your site needs.
What's included in a weekly service visit?
We pump the holding tank, restock toilet paper and hand sanitizer, and clean the interior. The tank holds 60 to 70 gallons between visits, which is typical for standard units. Any repairs needed get flagged on the service sheet.
Do you deliver to events in Cambridge?
Yes. Weddings, festivals, and outdoor gatherings near the Charles River or Cambridge Common are routine for us. Event rentals often include luxury restroom trailers if you want multiple stalls and running water on site.
Can I rent a porta potty for a home renovation?
Absolutely. A home renovation porta potty sits on most residential driveways. We handle single-unit rentals for contractors and homeowners doing work in Cambridge. Confirm truck access to your address before we schedule delivery.
