How many units do you actually need?
Start with worker or guest count, then match it to a real standard, not a guess. OSHA 1926.51(c) sets construction site ratios: 1 toilet for 20 or fewer workers, and 1 toilet plus 1 urinal per 40 workers once you pass that mark. Events run differently, and our guide to how many porta potties you need breaks down the ratio by hours and alcohol service. Field crews fall under a separate rule, OSHA 1928.110, which asks for one facility per 20 hand-labor employees within a quarter mile walk, relevant for growers using farm and agricultural restrooms. For general industry sites that aren't construction, 1910.141(c)(1)(i) applies instead. Once you have a number, check whether a standard unit covers it or whether you need a step up to a deluxe flushable model. Don't forget accessibility: ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, never fewer than one, which means most multi-unit Tustin job sites need at least one ADA accessible porta potty in the lineup.
What size and clearance does delivery need?
A standard unit measures about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your placement spot before the truck arrives. Tustin Porta Pros needs firm, level ground, and ADA Standards section 302.1 calls for stable, slip-resistant surfaces anyway, so gravel or a paved pad both work better than soft turf. If you're adding a restroom trailer instead, plan wider clearance: an 8 stall restroom trailer needs more room to maneuver than a 2 stall restroom trailer, and any trailer needs a clear approach path. Roll-off dumpsters have their own rule: leave about 60 feet of straight clearance behind the truck for the drop. If you're renting a roll-off dumpster alongside your restrooms, walk the site and mark both spots before delivery day. Check our porta potty placement guide for specifics on wind, slope and access-door orientation before you finalize the layout.
Does the site need a permit?
Placement in the public right of way needs confirming with the city before you commit to a curb-side spot in Tustin; we haven't verified a specific ordinance number, so ask the city directly rather than assume. If your unit sits entirely on private property, set back from sidewalks and driveways, permitting is usually simpler, but the same right-of-way question applies to temporary fencing and storage container placement near the street. Our porta potty permit requirements page walks through what to ask the city and when. Dumpsters often carry their own local rule too, covered in dumpster permit requirements. Don't skip this step for events near busy corridors. North Tustin sits about 3.1 miles north and Placentia about 12.6 miles north, and permit rules can differ block to block, so never assume what worked at one address applies at the next.
How often does service need to happen?
ANSI/PSAI Z4.3 sets the baseline: one service visit per week for up to 10 users across a 40 hour week. Busy events or multi-week construction jobs need tighter intervals, and our page on how often porta potties are cleaned explains how usage volume changes that schedule. Handwashing has its own separate requirement: 29 CFR 1910.141(d)(2) calls for soap and towels or a hand-drying device at wash stations, and hand sanitizer alone doesn't satisfy it, so pair your units with a proper handwashing station rental or portable sink rental rather than a sanitizer stand alone. If paint, coatings, herbicides or insecticides are part of the job, OSHA 1926.51(f)(1) requires washing facilities for that specific exposure, which matters for renovation crews using a home renovation porta potty setup. Septic tanks feed into this schedule too: a typical residential tank needs pumping every 3 to 5 years, and our septic pumping service page covers signs it's overdue.

How far in advance should I book in Tustin?
Book as soon as your date is set, especially for weekend events, since trailer and deluxe unit availability tightens fast. Construction jobs with ongoing service should lock in delivery windows a week ahead. Tustin event organizers booking wedding restroom rental or festival restroom rental units should confirm at least two weeks out.
What if I underestimate headcount?
Order one or two extra units past your OSHA 1926.51(c) minimum if turnout is uncertain. Adding a unit mid-event is harder than scaling down. Check emergency porta potty rental if you get caught short on short notice.
Do I need a handwashing station separate from the toilet?
Yes, if you want compliant handwashing. Toilet units alone don't satisfy 29 CFR 1910.141(d)(2)'s soap-and-towel requirement. Pair units with a hand sanitizer station rental or a full sink setup for food service or paint-related work.
Can I place a unit on the street in front of my house?
Maybe, but confirm with the city first. Right-of-way placement rules vary and Tustin Porta Pros can't guarantee curb placement without that confirmation. Setting back onto your driveway or yard usually avoids the question entirely.
What's the difference between a standard unit and a deluxe unit?
A standard unit is a basic 60 to 70 gallon tank unit built for job sites. A deluxe flushable porta potty adds a flush mechanism and nicer finish, priced higher per the table above, and suits events over rough construction work.
