How many portable toilets you need in Westminster

Jobsite counts follow OSHA 29 CFR 1926.51(c); event counts follow the ratios most health departments and event permits expect. Use this as a starting point, then tell us your exact Westminster crew or guest count and we size the order to code.

Which portable toilet do you need in Westminster?

Two questions size every order: how many people, and for how long. Here is how the five unit types map to the most common Westminster jobs.

Construction & jobsites

Standard units are the jobsite workhorse in Westminster. OSHA 1926.51(c) sets the minimum at 1 toilet for up to 20 workers, then 1 toilet plus 1 urinal per 40, and a unit has to be within about a 10-minute walk. On a Westminster job we winterize from early October into May, set units where the truck can reach them from a cleared street, and keep them well back from Standley Lake and the drainage paths that feed it.

Weddings & upscale events

Deluxe flushing units or a luxury restroom trailer are the guest-facing picks. A flushing bowl and in-unit sink change how the whole event is remembered. For 100-plus guests, one trailer plus standard units for peak load usually beats two trailers on cost.

Public & permitted events

The 2010 ADA Standards require at least 5 percent of single-user units at a public event to be accessible, minimum one, each marked with the accessibility symbol. Every unit has ground-level entry, grab bars, and a full turning radius. Tell us your guest count and we build the right ratio in.

Food service & health-code sites

Wherever food is served or sold, health codes expect hand-washing. Pair a hand-wash station (one per roughly four toilets) with your units. Food-heavy events get one station per two toilets, and inspectors look for one near the vendors.

Delivery & placement in Westminster

  • Same-day and next-day drop-offs

    We deliver across Westminster with same-day and next-day availability in most of the area when you book early. Weekend event units arrive clean before your event and leave after.

  • Level ground, clear approach

    Units place best on firm, level ground with a clear path for the delivery truck. Restroom trailers need a reasonably level spot and access for delivery, and we confirm the site details with you before the truck rolls.

  • Permits handled

    Private-property placement in Westminster generally needs no permit. Public streets, sidewalks, and permitted public events may require one. Tell us where the unit goes and we will confirm what your address needs.

Service & sanitation

  • 4 service visits per month, built in

    Every 28-day monthly rental in Westminster includes 4 service visits, roughly weekly. Each visit pumps the tank, sanitizes the interior, and restocks paper, soap, and sanitizer, so compliance never depends on a phone call.

  • Sized to OSHA 1926.51(c)

    The federal construction sanitation rule sets 1 toilet for up to 20 workers, then 1 toilet and 1 urinal per 40, with a 10-minute access rule. We size Westminster jobsites to that standard and add units when crews grow or usage climbs.

  • Hand-wash stations to code

    One hand-wash station serves roughly four toilet units, the ratio most health departments expect. For food-service events we recommend one station per two toilets, one near the vendors and one near the units.

What renting a porta potty in Westminster is actually like

Westminster sits between Arvada and Thornton along US 36, but it runs its own rules, and we do not service it like its neighbors. Three local realities shape almost every Westminster order: Standley Lake, a regional park that is also the drinking water supply for more than 300,000 people; a special event permit that starts at just 25 people and can apply even on private property; and a freeze window that runs from early October into May, with a wide swing between afternoon and night. Here is how each one changes what we recommend.

Why Westminster's long freeze window and wide daily swing shape service

At the weather station on Westminster's northeast side at about 5,370 feet, the 1991-2020 record puts the average first fall freeze around October 8, and it has come as early as mid-September. The average last spring freeze is around May 5, and in some years it has held off until late May. That is roughly seven months a year when a night can drop below freezing, even after a warm afternoon. We winterize units with a non-toxic antifreeze charge across that whole window, not just in midwinter, and we keep hand-wash stations with fresh water out of it unless the water can be managed.

The daily swing matters as much as the calendar. The same station averages about a 30-degree gap between the day's high and the night's low, wider still in July. A fall festival that starts in sunshine can end near freezing, and a unit that sat comfortably at noon can freeze overnight. In winter, the City of Westminster clears primary and secondary streets first, and residential streets only get service once snow tops about 8 inches, so on a neighborhood job we set the unit where our truck can reach it from a cleared street, on firm, level footing near the driveway apron.

Westminster's 25-person event permit and its fall and holiday calendar

Westminster sets a lower bar for events than most cities we serve. A Special Event - Temporary Use Permit is required for any public event that expects 25 or more people on City property, including parks, trails, open space, sidewalks, and streets. It also applies on private property when a public event spreads out of the building into the parking lot, onto a neighboring lot, or into the street, which covers tent sales, car shows, farmers markets, chile roasting, and holiday tree lots. The city asks for the application at least 45 days ahead. We build the restroom count and placement into that site plan with you, so the permit and the order match.

The city's own calendar runs strong into the cold months. Westy Fest fills Westminster City Park in mid-October with carnival games, food trucks, live music, and a hot-air balloon glow that runs after dark, and the Holiday Lighting Ceremony at City Hall in early December is mostly outdoors. Both fall inside the freeze window. For fall and holiday events we winterize the units, add hand sanitizer where running water could freeze, light the path to the bank for after-dark crowds, and place units on pavement or firm ground so the service truck can reach them.

Placement near Standley Lake and in the City of Westminster right-of-way

Standley Lake is more than a park. Its 1,063-acre reservoir, the third-largest in the Denver metro, is the primary drinking water supply for Westminster, Thornton, and Northglenn, serving more than 300,000 people, which is why no swimming or wading is allowed. Events there go through a separate Standley Lake application. On any job or event near the lake, or near the creeks and channels that feed the city's water, we set units on level, hard ground well back from the shoreline and drainage paths, service them on schedule so tanks never run near full, and route the pump truck on established roads only.

On private property, a driveway, a fenced jobsite, or a commercial pad with clear truck access, you generally do not need a city permit for the unit itself, though a public event that spills into a parking lot does need the event permit. Anything in a city street or sidewalk is a right-of-way matter. The City of Westminster Engineering Division reviews right-of-way permits under the City Engineer, applications and traffic control plans go through the online permit portal only, and the work must be done by a contractor holding a city public way contractor's license. Westminster publishes no separate portable-toilet permit, so tell us the exact address and whether the spot is private or in the street, and we confirm what it needs and coordinate it before delivery. See the City of Westminster right-of-way permit page.

OSHA's construction sanitation rule, 29 CFR 1926.51(c)(1), sets the floor: 1 toilet for 20 or fewer workers; 1 toilet seat and 1 urinal per 40 workers from 20 up to 200; and 1 toilet seat and 1 urinal per 50 workers above 200. OSHA also expects a worker to reach a toilet within about a 10-minute walk. On a Westminster jobsite, a roughly 30-degree swing between afternoon and night means a crew can work hot and a unit can still freeze overnight, so we recommend sizing above the OSHA minimum in summer and winterizing across the full freeze window from early October into May. Tell us the crew size and we will size the order to the standard.

Our standard Westminster monthly rental includes 4 service visits over the 28-day period, roughly weekly. Each visit pumps the tank, sanitizes the interior, and restocks paper, soap, and hand sanitizer. In summer we add a mid-week visit for large crews and busy events. Because nights can freeze from early October into May, we winterize units across that whole window and plan winter service from streets the city has cleared, since residential streets are only plowed after about 8 inches of snow. Near Standley Lake and its drainage we keep service on a strict schedule so tanks never run close to full. Service is built into the rate, so compliance never depends on anyone remembering to call.

For an event open to the public, yes. The 2010 ADA Standards for Accessible Design require that at least 5 percent of the single-user portable toilets in each cluster be accessible, with a minimum of one, and each accessible unit is marked with the International Symbol of Accessibility. (Units provided only for construction workers are exempt.) In practice a small Westminster event needs at least one accessible unit; a larger one needs one per every 20 standard units. ADA units in Westminster run $374 for a weekend. The accessible unit has ground-level entry, interior grab bars, and a full wheelchair turning radius, and it needs firm, level ground with a clear approach path. Tell us your guest count and we will build the right ratio in.

On private property in Westminster, a driveway, a fenced jobsite, or a commercial pad with clear truck access, you generally do not need a city permit for a portable toilet on its own. Two things change that. A public event of 25 or more people on City property, or one that spills from a private building into a parking lot or the street, needs a Special Event - Temporary Use Permit. And anything placed in a public street or sidewalk is a right-of-way matter reviewed by the City of Westminster Engineering Division, applied for online by a contractor holding a city public way contractor's license. Westminster publishes no separate portable-toilet permit, so tell us the exact address and use, and we confirm what it needs and coordinate it before delivery.

A standard unit is the jobsite and everyday-event workhorse: enclosed, stocked, and cost-effective at $270/weekend. A deluxe flushing unit adds a foot-pump flushing bowl and an in-unit sink for guest-facing events like weddings and corporate functions at $374/weekend. A luxury restroom trailer is a climate-controlled, multi-stall unit with porcelain toilets, running-water sinks, and mirrors, indistinguishable from a fine-venue bathroom, from $1610/weekend. Pick by how guest-facing the site is and how long the rental runs.

Yes. We deliver and service portable toilets throughout Westminster and the surrounding Westminster metro area, with same-day and next-day drop-offs available in most of the area when you book early. Weekend event units are delivered clean before your event and picked up after. Enter your ZIP or call (866) 858-3867 and we will confirm the soonest available delivery for your address.

Yes. A freestanding hand-wash station pairs with any toilet unit and needs no power or water hookup: it has a foot-pump faucet, soap, and paper towels, stocked at delivery and every service visit. One station serves roughly four toilet units, the ratio most health departments expect. For food and drink events in Westminster, plan a station near the vendors and one near the toilets to cover both inspection points.

Often, yes, and at a lower threshold than you might expect. Westminster requires a Special Event - Temporary Use Permit for a public event that expects 25 or more people on City property, and also for a public event on private property that spreads into the parking lot, a neighboring lot, or the street. The city asks for the application at least 45 days ahead, and events at Standley Lake use a separate application. The restrooms themselves are part of your site plan, so send us your date, expected peak crowd, and layout, and we size the bank, add hand-wash stations near food, and place the units so the plan you submit matches what we deliver. For October and December events we also winterize, since Westminster nights can freeze from early October into May.

How Westminster porta potty rental connects to the rest of the job

Portable sanitation rarely stands alone. These are the related decisions that come up on the same Westminster project, and where to handle each one.

Site debris & cleanup

A porta potty and a roll-off dumpster share the same jobsite footprint and the same right-of-way permit path in Westminster. Crews that need one usually need the other.

Westminster dumpster rental

OSHA jobsite compliance

Toilet counts are one line in OSHA 1926.51(c). Hand-wash stations, water, and sanitary condition are the rest of the sanitation standard for a compliant crew.

Construction porta potties

Upscale & public events

Guest-facing events trade the standard unit for flushing units or a restroom trailer, and the ADA 5 percent accessible-unit rule kicks in the moment the event is open to the public.
