OSHA rule 29 CFR 1926.51 sets the sanitation standard behind every Boston construction rental: one toilet for up to 20 workers, two for 20, 199, and one per additional 40 workers above that. A single standard unit measures roughly 43 inches square and 92 inches tall and fits inside a parking-space footprint, which matters on tight lots in South Boston and the row-house streets of Charlestown where lay-down space is scarce. The 60-gallon holding tank supports about 10 full-time workers across a standard week before the scheduled pump-out.
Unit choice follows crew size and job type. A standard non-flush unit fits general framing, demolition, and roofing crews under 10 workers. A deluxe flushing unit with a foot pump and interior sink suits longer high-rise fit-outs in Back Bay and the Seaport where crews stay put for months. An ADA-compliant wheelchair-accessible unit, roughly 5 feet wide inside with a ground-level entry, is required on federal and many City of Boston public projects. A solar-vent or winterized unit adds cold-weather protection for jobs running through a New England January. If a Roxbury or Dorchester crew exceeds 10 workers, adding a second unit costs less per person than doubling the weekly cleaning on one.
Weekly service is the core of a construction contract: a truck vacuums the tank, refills the deodorizer charge, restocks tissue and hand sanitizer, and sanitizes the seat and interior. Two cleanings per week are available for crews above 20 workers or summer jobs near Franklin Park where heat accelerates odor. Placement needs a firm, level pad within about 25 feet of truck access so the vacuum hose reaches; muddy or sloped lots in Hyde Park and West Roxbury may need gravel or a plywood base. Streets requiring a unit on a public sidewalk or travel lane, common in East Boston and Jamaica Plain, need a City of Boston occupancy permit, which the site contractor typically secures before delivery.
A construction rental differs from an event rental: it is a month-to-month agreement built for continuous jobsite use with recurring service, not a weekend drop-and-collect. Monthly billing continues until pickup is scheduled, so calling to remove the unit at final punch-list ends the charge. Delivery reaches jobsites across South Boston, Dorchester, Roxbury, Jamaica Plain, Charlestown, East Boston, Back Bay, Roslindale, West Roxbury, and Hyde Park.
