Does a construction site need an ADA unit for a crew of 12?

Yes, you need an ADA-compliant portable toilet for a crew of 12. The city inspector is correct. OSHA 29 CFR 1926.51 sets minimum toilet numbers for construction sites, but the ADA Standards for Accessible Design require accessibility regardless of crew size or ability.

OSHA minimums
OSHA 1926.51(c) says 20 or fewer workers need one toilet. Your crew of 12 meets that with one standard unit. But OSHA does not override the ADA.

ADA cluster rule
The 2010 ADA Standards require that where portable toilets are provided, at least one must be accessible if multiple units are clustered. Since you have one unit, it's a cluster of one. The rule applies to any temporary toilet facility on a job site accessible to the public or employees.

Enforcement
City inspectors enforce both OSHA and ADA rules. Failing to provide an accessible unit can result in fines and stop-work orders. It doesn't matter if your crew is all able-bodied; the rule is about providing equal access.

Order an ADA-compliant unit. It has a wider door, grab bars, and turning space. Your rental company can swap your standard unit for one. It's a straightforward fix. Any questions on placement or service?

Yes, a construction site with a crew of 12 needs an ADA-compliant portable toilet. OSHA 29 CFR 1926.51 sets the minimum number of units, requiring one toilet for 20 or fewer workers. The 2010 ADA Standards for Accessible Design require accessibility for any portable toilet provided to employees or the public. The ADA 5 percent cluster rule states that where multiple single-user portable toilets are clustered, at least one must be accessible. A single unit is considered a cluster of one. This rule applies regardless of the current crew's abilities. City inspectors routinely check for compliance with both OSHA and ADA rules. An ADA-compliant portable toilet has a wider door, interior grab bars, and the required wheelchair turning space. Order one from your rental company to replace the standard unit. The rental cost is driven by the unit type and the service frequency, which is typically weekly for normal use.

Marcus is correct, but the inspector will also verify the ADA unit is properly identified. The 2010 ADA Standards require the unit to be identified with the International Symbol of Accessibility. On a construction site, the inspector checks that the accessible unit is on firm, level ground and that the path to it is free of obstructions. If you are swapping a standard unit for an ADA unit, ensure the rental company knows the exact location for the delivery driver. The driver will need the same truck access for service. The service frequency for an ADA unit on a construction site is the same weekly norm, but a larger crew using it may require more frequent pumping.

The city inspector will check that the ADA unit is on firm, level ground and that the path to it is accessible, which includes being clear of stored materials and debris. The rental company's driver needs the same truck access for the weekly service visit to pump the holding tank and restock supplies. If your site conditions change and block the unit, it will be logged as a missed service, and you may be billed for the trip. For a crew of 12, one ADA-compliant unit satisfies both the OSHA minimum and the ADA requirement.
