Maryland porta potty requirements
MOSH adopts federal OSHA construction sanitation, so Table D-1 is the worker-count floor. Maryland then adds COMAR rules for the unit itself: authorization after 3 days, a maintenance agreement, and a licensed septage hauler. Festivals use a different health-permit table. This is planning guidance, not legal advice.
Rule: OSHA Table D-1 via MOSH + COMAR 26.04.02.08. COMAR 26.04.02.08

What the rule actually says
- Construction worker counts follow OSHA Table D-1 (1 toilet for 20 or fewer; then 1 seat and 1 urinal per 40, or per 50 at 200+)
- A portable unit past 3 days in a 60-day window needs Approving Authority authorization
- Maintenance agreement and licensed septage hauler required
- Chemical toilets must be impervious, vented above the roof line, and chemically charged
- Outdoor musical festivals: 1 male and 1 female toilet per 200 spectators, with matching hand-wash and daily pump-out
The recommended column uses 1 unit per 10 workers so weekly service stays sanitary.
Confirm the local health department / Approving Authority for a monthly construction stop.
FAQ
Does Maryland follow OSHA or its own toilet ratio?
MOSH adopts 29 CFR 1926, so construction sites use OSHA Table D-1. COMAR 26.04.02.08 adds authorization, servicing, and chemical-toilet construction rules.
How many porta potties for a Maryland festival?
COMAR 10.16.05.05 requires one designated male toilet and one designated female toilet per 200 spectators, matching hand-wash, and a daily pump-out contract if the facilities are portable.
