How much does a 4 stall restroom trailer cost in Baltimore?
Pricing depends on how long you need it and how far the trailer travels to get there. A single-day booking sits at the low end, weekly rentals cost more overall but less per day, and multi-week jobs land in the highest bracket. Check the restroom trailer rental cost page for the full breakdown across all trailer sizes, or compare against a 2 stall restroom trailer if four stalls is more than your guest count needs. Delivery is billed separately and depends on distance from our staging point, similar to how we quote a roll-off dumpster rental or a storage container rental job.
| unit | duration | low | typical | high |
|---|---|---|---|---|
| trailer | day | 175 | 800 | 2500 |
| trailer | week | 150 | 1397 | 1650 |
| trailer | weekend | 900 | 2000 | 3000 |
| trailer | event | 2499 | 3500 | 3899 |
A weekend rental in Baltimore runs in that same weekend band above, which covers Friday drop-off through Monday pickup for most events. If your event runs longer, the event restroom rental page walks through multi-day pricing logic in more detail.
Where can a 4 stall restroom trailer be placed on my property?
The trailer needs level, stable ground, and our crew checks the site before delivery day. ADA Standards section 302.1 calls for floor and ground surfaces that are stable, firm and slip resistant, and we apply that same standard to the pad we set the trailer on. If your site sits on a slope or gravel, tell us ahead of time so we can plan blocking. For guidance on clearances and placement in general, see the porta potty placement guide, and if you need a fully accessible unit alongside the trailer, the ADA accessible porta potty page covers ADA Standards section 213.2, which requires at least one accessible unit in any cluster.
Baltimore properties with tight alleys or narrow driveways should measure before booking. If a roll-off or storage container is also coming to the same site, remember a roll-off delivery needs about 60 feet of straight clearance behind the truck, and the same access rules generally apply to trailer delivery. Homeowners tackling a renovation should also look at home renovation porta potty options if a full trailer is more than the crew needs.
Do I need a permit for a restroom trailer in Baltimore?
Permit rules vary by property and by how long the trailer sits in place, so confirming with the city before delivery day is the safest move, especially for anything set in the public right of way. We do not guess at ordinance numbers here. If your event or job site also involves a dumpster or temporary fencing, check dumpster permit requirements and porta potty permit requirements for the same reason. Weddings held on private venue grounds in Baltimore typically avoid most of this, but a street closure or sidewalk placement changes the answer fast.
Our crew has handled deliveries from Towson, roughly 8.0 miles north of Baltimore, out to Dundalk, about 8.1 miles east, and permit questions come up more often in dense city blocks than in open lots. Ask us during your request a quote call and we will flag anything that needs city sign-off before we lock in a date.
How many people can a 4 stall restroom trailer handle?
Four stalls comfortably serve a wedding or corporate event in the 150 to 300 guest range for a single day, depending on bar service and how long the event runs. For larger crowds, pair it with standard porta potty rental units or step up to an 8 stall restroom trailer.
Does the trailer need a water and power hookup?
Yes. Most 4 stall units run on a garden hose connection and standard household power, though some luxury models need more. Ask about hookup specifics when you book, and see luxury restroom trailer for higher-end configurations.
Can I rent a 4 stall trailer for a construction site?
Yes, though most job sites lean toward standard units for cost reasons. OSHA 1926.51(c) sets toilet counts by crew size, and a trailer can satisfy that requirement while adding a nicer break option. See construction site services for how we scope larger sites.
How often is the trailer serviced during a multi-week rental?
Weekly servicing is standard, consistent with the ANSI/PSAI Z4.3 baseline interval used across the portable sanitation industry. Longer bookings get a set schedule confirmed at drop-off, and you can adjust frequency for heavy-use events.
What is the difference between a 2 stall and 4 stall trailer?
A 2 stall handles smaller gatherings or short crews, while four stalls cuts wait times for events over roughly 150 guests. Compare footprints and pricing on the 2 stall restroom trailer page before deciding which fits your Baltimore event.
