Frequently Asked Questions in Mission Viejo, CA

The count depends on your workers and duration. For construction sites, OSHA 1926.51(c)(1) requires 1 toilet facility for 20 workers or fewer; 1 toilet seat and 1 urinal per 40 workers from 20 up; and 1 toilet seat and 1 urinal per 50 workers at 200 or more. An event with 150 guests needs different math than a renovation crew of eight. Call us with your headcount and we'll spec the right number. See how many porta potties do I need for the full breakdown. Every site in Mission Viejo is different. A standard unit holds 60 to 70 gallons and takes about 44 by 48 inches of ground space.

A standard porta potty is a single-stall outhouse on wheels. It has a toilet seat, a holding tank and a vent stack. Deluxe models add a hand sanitizer dispenser and a flushing mechanism. Neither a standard nor a deluxe flushable porta potty includes running water; flushing models use tank water only. If your site requires actual handwashing with soap and water per 29 CFR 1910.141(d)(2), you need a handwashing station rental. Many Mission Viejo construction projects rent both: a toilet for privacy and a sink station nearby. Rental costs vary by duration and unit type.

Yes, if your site is open to the public or employs anyone with mobility limits. An ADA accessible porta potty meets the minimum clear width of 36 inches per ADA Standards section 403.5.1, has grab bars, and provides a 60 inch diameter turning circle per ADA Standards section 304.3.1. ADA Standards section 213.2 says that where single-user units are clustered, at least 5 percent of the group, and never fewer than one, must be accessible. In Mission Viejo, this matters for job sites, festivals, weddings and any event open to guests. Standard units don't meet the code. ADA units cost more but they're required law, not optional.

A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. Pumping removes solids that collect at the bottom. If you notice slow drains, soggy ground near the tank or sewage smell in your yard, call for service right away. Mission Viejo homes on septic often pump more frequently than homes on city sewer because heavy rain and high water tables affect tank drainage. See septic tank pumping cost and how often to pump a septic tank for details. A grease interceptor is pumped when fats, oils, grease and solids reach 25 percent of the liquid depth. Don't wait until it backs up.

Hazardous waste, tires, batteries, paint, propane tanks and electronics are prohibited. Asbestos, medical waste and radioactive material are illegal to dump. Concrete, dirt and roofing shingles often cost extra because they're heavy. Check what cannot go in a dumpster before you load. Mission Viejo construction sites generate tons of scrap. A roll-off dumpster rental takes demolition debris, but not hazmat. Rental fees and weight limits vary by dumpster size. Call before you rent so we can quote you correctly on what you're actually throwing.
