Frequently Asked Questions in Southfield, MI

Southfield Porta Pros rents portable toilets, septic pumping, roll-off dumpsters, storage containers, restroom trailers, temporary fencing and handwashing stations. Standard units cost 100 to 350 dollars per day, weekly rentals run 130 to 500 dollars, and monthly rentals span 125 to 325 dollars. We answer the questions our customers ask most often about placement, costs, cleaning frequency, OSHA compliance and what works best for different jobs.

How many portable toilets do I need?

OSHA 1926.51(c)(1) sets the baseline: one toilet facility for 20 workers or fewer; one toilet seat and one urinal per 40 workers from 20 up; one toilet seat and one urinal per 50 workers at 200 or more. That's the legal minimum for construction sites. For events, the math shifts, a wedding or festival needs roughly one unit per 75 guests. A residential renovation crew in Southfield might need just one standard unit. A multi-phase commercial build could need three or four plus a restroom trailer if the project runs months. Call us for a quick count based on your crew size and job length.

What's the real cost difference between daily, weekly and monthly rental?

Daily rates run higher per day than weekly rates, and weekly rates run higher per day than monthly rates. A standard porta potty on a single day typically falls in the 100 to 350 dollar range, depending on your delivery location in Southfield and service adds. Weekly rentals run 130 to 500 dollars per week. Monthly rentals span 125 to 325 dollars per month. Delivery and service fees vary by duration and distance. Check our pricing page for exact rates in your area, or email us a job description and we'll quote it same-day.

How often does Southfield Porta Pros service a unit?

Standard service for up to 10 users over a 40-hour work week is one visit per week, per ANSI/PSAI Z4.3 industry standard. Heavier use, festivals, construction sites with 20+ workers, needs twice-weekly service or more. A deluxe flushable unit may need service every five days on a busy job. We also offer emergency same-day service if a site goes down. Tell us your user count and job type when you call, and we'll set a service schedule that keeps the unit clean and compliant.

Do I need an ADA unit and what does that cost?

Yes, if your Southfield site or event has public access or employees with disabilities. ADA Standards section 213.2 requires that at least five percent of clustered units be accessible, and never fewer than one. An ADA accessible porta potty costs more per day than a standard unit, but you rent it only once per site. ADA units have a 36-inch minimum clear route width per ADA Standards section 403.5.1, a 32-inch clear door opening per ADA Standards section 404.2.3, and a 60-inch turning circle per ADA Standards section 304.3.1. Pricing for ADA units runs higher than standard; request a quote if your event or work site needs accessible facilities.

How often should we pump our septic tank?

A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. Grease interceptors go on a different schedule, pump them when fats, oils, grease and solids reach 25 percent of the liquid depth. If your Southfield home or business has slow drains, raw sewage backups or wet spots over the tank, call Southfield Porta Pros for emergency septic service. A grease trap pumping visit costs less if you stay on schedule; emergency calls cost more. Learn the warning signs on our septic guide.

Why does temporary fencing cost different amounts per day?

Fence rental prices depend on total linear feet, terrain, wind load and installation labor. A temporary fence around a 50-by-50-foot lot costs less than one around two acres. Call with your site dimensions and we'll quote it fast.

Can I rent a handwashing station instead of a full restroom trailer?

Yes. Portable sinks work well for crews that don't need toilets. Per 29 CFR 1910.141(d)(2), they must have soap and towels or a hand drying device, hand sanitizer alone doesn't meet code. They're cheaper than restroom trailers and take up less space.

How long does a roll-off dumpster delivery take in Southfield?

A standard roll-off dumpster needs about 60 feet of straight clearance behind the truck to drop safely. Tight driveways add time. Most deliveries in Southfield take one to two hours from our dispatch.

What can't go in a roll-off dumpster?

Hazardous waste, tires, batteries, asbestos and liquids are banned. See our full list before you load. Violations can trigger fines or your entire dumpster being quarantined.

Do portable toilets work in winter?

Yes. Southfield winters freeze lines and slow decomposition, but modern units stay functional. We use RV-grade antifreeze and service more often in December through March to prevent tank freeze-ups and backup. Cold weather rentals cost more; call for winter rates.
