Porta Potty Rental in Chula Vista, CA 91911

Two very different rules apply here, and mixing them up is the usual mistake.

• Chula Vista job sites, the California count: one separate toilet facility for every 20 employees or part of 20, of each sex, with no upper cut-off, so the figure keeps rising as the crew grows. Twenty mixed workers on an Otay Ranch slab need two facilities, not one. See the California construction toilet standard.
• The small-crew exception: with fewer than five employees on site, one single-user all-gender unit does the whole job.
• Washing stations, counted separately: one for every 20 employees or part of 20, stocked with clean water, soap and single-use towels or a blower, and placed so anyone leaving a toilet can wash at once. Paired with a chemical unit it must carry a washing-water notice and sit outside the unit, unattached, under the California washing facilities standard. The same under-five case is the one exception, where the washing point may be inside.
• Sinks are a state duty too. California's construction washing rule calls for washing facilities on the job and sets the count and the placement, so never treat the sink as a nice-to-have.
• South bay events, the county schedule: San Diego County's health department publishes a sanitary facilities schedule for temporary community events. One facility per 150 people at a stationary event, one per 200 for a moving one such as a parade or a 10K, one accessible unit at every event plus another for each set of 25 standard units, and one handwashing station at every event plus another for each set of 20 required units. Read the county sanitary facilities schedule.
• The clause worth knowing: an event of five hours or less may halve the required count, but that discount disappears entirely once alcohol is served. Alcohol does not raise the ratio here. It removes your short-event saving.
• Food booths carry their own California count: at least one toilet per 15 food employees within 200 feet of each temporary food facility, each with handwashing, under the California Retail Food Code. That total sits on top of your guest provision.
• Chula Vista itself sets no ratio. The City publishes no event restroom figure, so the judgment is yours and your account manager's.
