Military and Federal Restrooms

Mavirus Group supplies government restroom trailers for San Diego military and federal sites

Few places in the country pack as many military commands into one county as San Diego. Navy piers line the bay, special warfare units train on the Silver Strand and Marines maneuver across the hills of Camp Pendleton. Field exercises and base construction regularly outgrow the restrooms a base already has. Mavirus Group brings private restroom trailers that meet those needs and keeps them serviced on a calendar the unit approves. We are SAM.gov registered, licensed and insured, and we plan gate access before the truck ever leaves. Call us with your dates and location, or request a quote and we'll build the plan around your security office.

★★★★★

We had about 400 people in the field for a week. The trailers were set the day before we arrived and pumped every night after training. Nobody had to leave the training area for a restroom.

★★★★★

Our building was under renovation and half the restrooms were closed. The trailer outside looked clean and professional, and our sailors used it without a single complaint for three months.

The salt air eats everything on the pier. Their tech checked the steps and hinges every visit and swapped a door closer before it failed.

Our Restroom Trailer Fleet

The private restroom trailers we deliver to San Diego bases and federal jobsites

A Mavirus luxury restroom trailer with private flushing suites, ready for San Diego delivery
The 8-Station unit, eight locking private stalls sized for a field exercise or a busy base worksite

Our 8-Station Private Stall Deluxe unit is built for large groups. Eight private stalls each hold a toilet, a urinal and a sink behind a locking door, so the trailer can serve anyone in any order. A 400 gallon fresh water tank and a 1,000 gallon waste tank carry it through long days between pump-outs. Two air conditioners keep the inside comfortable on an inland afternoon at Miramar or Pendleton.

The ADA +6 trailer adds accessible capacity. It has a unisex accessible room with a self-contained ramp built to federal and California standards, plus four men's and two women's stations. It suits a command post or a public-facing federal site. Plan on a footprint of 31 feet long and 13 feet 6 inches wide with the ramp in use. Units in the field can be joined by shower trailer rentals in California for field exercises on one order.

Small crews get the 2-Station unit, with one women's and one men's room on a single 20 amp, 120 volt circuit. It fits a range road turnout or a pier apron. Every model carries its own fresh water and waste tanks, so it works where there is no sewer tie-in, and it connects to site water and power when those are close. Our techs pump, clean and restock on the schedule set with your logistics lead. For a field exercise with a few hundred people, we usually start with two 8-Station units near the tent line and one ADA +6 near the command post. A small survey or range crew often needs only a 2-Station unit.

San Diego Restroom Work

Where our portable restroom units work across San Diego County

Restroom trailer work in San Diego follows the military first. Navy commands around the bay and Marine Corps bases to the north run exercises, construction and events that need extra facilities. Large public and private builds come next, from the airport to Mission Valley. County emergency response rounds it out, shaped by Santa Ana wind fires that can move faster than almost anywhere else in the state.

Navy Commands on the Bay

Restroom trailers for Naval Base San Diego, Point Loma and Coronado

Naval Base San Diego is the principal homeport of the U.S. Pacific Fleet. It stretches across 13 piers, about 1,600 acres of land and 326 acres of water. More than 50 ships and more than 150 tenant commands work from it. A base that size runs a steady stream of construction, repair and training that goes beyond its fixed restrooms.

Training shows up on the calendar too. In January 2026, a large exercise at Naval Base San Diego raised security and traffic around the base. Exercises like that move people into areas far from a building, and each one needs restrooms placed where the people actually are.

Across the bay, Naval Base Point Loma brings together seven component facilities, including a submarine base. Naval Amphibious Base Coronado sits on the Silver Strand between the bay and the ocean and supports more than 30 tenant commands. It is the West Coast hub for special and expeditionary warfare training. Beach and range training there often runs far from permanent facilities.

The NASSCO shipyard sits next to Naval Base San Diego's Gate 2 and builds and repairs ships under Navy contracts. Shipyard crews work along the waterfront, often a long walk from a restroom. We plan pier and yard placement with your safety office and set service around shift changes. For base-wide field support, see our military base camp restroom trailers for San Diego installations.

Marine Corps Training

Field restroom trailers for Camp Pendleton and MCAS Miramar exercises

Camp Pendleton in North County has 17 miles of coastline and about 125,000 acres of maneuver land. It is the Marine Corps' main West Coast amphibious training base and home to I Marine Expeditionary Force. Training there spreads across hills, canyons and beaches where the nearest building may be miles away.

Marine Corps Air Station Miramar hosts the 3rd Marine Aircraft Wing and runs large regional exercises. Exercise Semper Durus in May 2025 spanned Camp Pendleton, Miramar, MCAS Yuma and the logistics base at Barstow. It was built to test emergency readiness and rapid response across all of those sites.

Field exercises create a restroom need that looks like a small town popping up for a week. Hundreds of people arrive on day one, work long shifts and leave on the last day. Garrison restrooms are rarely close to the training area. A row of trailers near the tent line keeps troops in place and cuts wasted drive time.

We plan exercise support with the unit's logistics staff. Tell us the grid location, the road in and the start and end dates. We'll set units near the tent line and the dining area, with an accessible unit near the command post. Service runs on a set schedule, and we can pump at night so trucks stay off range roads during training hours.

Airport, Stadium and Transit Builds

Construction restroom trailers for San Diego airport, Mission Valley and downtown projects

San Diego International Airport is in the middle of a major rebuild. Construction on Phase 1B started in early 2026, three new gates opened that spring and the remaining eight gates are expected by early 2028. Airside work runs under tight security, and every vehicle on the ramp needs an escort and a plan.

Mission Valley has its own long build. SDSU Mission Valley pairs Snapdragon Stadium with an innovation district, housing and more than 80 acres of parks, including a 34-acre River Park. The first apartment phase, 621 units at Avalon Mission Valley, broke ground in August 2025 and targets early 2028. Nearby, the 48-acre Midway Rising site plans housing and a roughly 16,000-seat arena, with work phased from 2027 into 2029.

Downtown, work on a new transit platform was set to start in spring 2026 and run about 18 months. Title 8 Section 1526 governs toilets on all of these sites. It calls for clean, private and stocked facilities, and it allows nonwater-carriage units where a sewer isn't practical. Long stretches of Mission Valley and Midway Rising sit on ground with no sewer ready yet, which is where a self-contained trailer fits.

Big builds grow in stages. We start with a small unit during site work and add 8-Station trailers as the trades arrive. Contractors planning statewide can compare our California portable restroom units for airport and stadium builds. Send us the phasing plan, and we'll quote the units for each stage.

Other San Diego sites that rent our portable restroom units

San Diego Unified campus projects

The district's building program runs on Propositions S and Z and Measures YY and U. Staff shared a first look at a new bond ask in June 2026. Whole-site modernizations often close restroom wings while students stay on campus.

UC San Diego housing and labs

UC San Diego enrolled 35,442 undergraduates in fall 2025. Campuses that size keep building housing and research space year after year. We time service around finals and move-in weeks.

Otay Mesa border infrastructure

The planned Otay Mesa East Port of Entry sits about two miles east of the current crossing. Flat mesa ground and busy truck traffic make restroom placement a real planning job on border work.

County repair and remodel contracts

The county uses Job Order Contracts for competitively bid repair and remodel work. Crews on those jobs often work in occupied buildings. A trailer outside keeps public restrooms open for the people the building serves.

Outreach and inclement weather sites

The city's Coordinated Street Outreach Program fields more than 40 contracted outreach workers. The county runs an Inclement Weather Program during severe weather. Outreach sites often need clean, accessible restrooms on short notice.

Service Area

Restroom trailer delivery across San Diego, Chula Vista, Oceanside and Escondido

We deliver across San Diego County, from the border at Otay Mesa to the Camp Pendleton corridor and east into the backcountry. Our service area covers all 50 states, with rapid deployment for military programs and emergencies. Send us the gate, the dates and the road in, and we'll build the delivery plan.

Santa Ana Winds and Heat

How Santa Ana winds and inland heat change restroom trailer planning in San Diego

Most San Diego summer days stay mild near the coast. Santa Ana winds change that. Dry desert air blows west toward the coast and warms as it drops out of the mountains. The city's record highs, 111 degrees in September and 107 in October, both came during Santa Ana conditions rather than midsummer.

Those winds drive the county's worst fires. The Cedar Fire in 2003 burned 273,246 acres, destroyed 2,820 structures and killed 15 people, spreading as fast as 3,600 acres an hour. The Witch Creek Fire in 2007 burned 197,990 acres and led to the evacuation of about 500,000 people in the county. Shelters and base camps after events like those need restrooms fast. Agencies planning for that can read about San Diego County wildfire base camp restroom trailers.

Wind days also bring power shutoffs. San Diego Gas and Electric may cut power to lines during high fire risk to prevent new fires. Our units flush from their own tanks, but lights and air conditioning need power. Tell us if your site sits in a shutoff zone, and we'll plan backup power and extra service before the wind arrives. Inland crews face heat too, and Cal/OSHA has issued heat advisories for the county when inland highs reach 95 to 100 degrees.

Why Choose Us

What you get when you rent a portable restroom unit from Mavirus Group in San Diego

Night service on training ranges

During exercises, our crews can pump and clean after dark so service trucks stay off range roads while training runs.

Units staged ahead of fire weather

When a Red Flag Warning is posted, we can hold units ready for county shelters so a call becomes a delivery instead of a search.

One account for many commands

Separate tenant commands on the same base can bill to their own lines under one account. Each command sees only its own units and invoices.

Salt air care on the waterfront

Units on piers and near the surf get extra checks on steps, hinges and fittings. We catch corrosion early so doors and rails keep working.

Customer Stories

How a typical San Diego restroom trailer job is set up

How we would set up restrooms for a week-long Camp Pendleton field exercise

We'd stage two 8-Station units near the tent line and an ADA +6 beside the command post a day before troops arrive. Pump-outs would run each night after training ends. On the last day, we'd pull every unit after the final convoy leaves.

How we would set up restrooms for a ship repair crew on the bay

For a crew working a long pier, we'd place a 2-Station unit at the head of the pier and an 8-Station unit near the yard gate. Service would fall between shifts. Salt-air checks on the steps and doors would happen on every visit.

How we would set up restrooms for a Mission Valley apartment build

During grading, a single 2-Station unit would sit near the site office. When framing starts, we'd add an 8-Station unit at the main gate. Each change would follow the general contractor's phasing plan, with no new paperwork.

Sanitation Rules

Cal/OSHA sanitation and heat rules our San Diego restroom trailers are set up for

Title 8 Section 1526 applies to every California construction site with more than one worker. Toilets must be kept clean and in good working order, designed for privacy and stocked with toilet paper. Where a sanitary sewer or adequate water supply isn't practical, nonwater-carriage toilets are allowed. That covers early phases of Mission Valley, Midway Rising and many waterfront jobs.

Section 3366 sets the washing-facility rule for general industry, with running water and cleansing agents within reasonable reach of workers. Both sections now allow single-user toilets to be marked all-gender under Health and Safety Code Section 118600. Cal/OSHA still enforces the total number of fixtures. Our private stalls can serve anyone, which keeps the math simple.

Heat rules apply here as they do statewide. Section 3395 calls for cool drinking water, shade once it passes 80 degrees and high-heat procedures starting at 95. Construction and landscaping are among the industries named for extra high-heat protections. Restrooms close to the work help crews keep drinking through a hot inland day, and we'll show your safety lead where each unit sits and how service is logged.

FAQ

Frequently asked questions

Can you deliver restroom trailers onto Naval Base San Diego or Camp Pendleton?
Yes. We deliver to military installations and plan gate access early. Send us your security office contact and any escort rules. We'll send driver and vehicle details days ahead so the truck clears the gate on arrival.
How many restroom stations does a field training exercise need?
It depends on the head count, the length of the exercise and how the day is split. For a few hundred people, two 8-Station units near the tent line and an ADA +6 near the command post is a common starting point. Send us your numbers, and we'll size it.
Can you service units at night during training?
Yes. We can pump and clean after training ends so trucks stay off range roads during the day. Tell us the quiet hours and the route in, and we'll schedule around both.
Are you registered to work with federal contracting offices?
Yes. Mavirus Group is SAM.gov registered with an active CAGE code and UEI, and we're licensed and insured. We write quotes in the format your contracting office requests.
Do restroom trailers work on a pier or near salt water?
Yes, with extra care. We set units on firm, level ground away from wave splash, and our techs check steps, hinges and fittings on every visit. Salt air wears metal faster, so we look for corrosion before it causes a problem.
What happens to a restroom trailer during a power shutoff?
Toilets flush from the unit's own tanks, but lights and air conditioning need power. If your site is in a shutoff zone, tell us ahead of time. We'll plan backup power and move up service before the wind event.
Can you supply restrooms for a wildfire evacuation shelter in San Diego County?
Yes. We set units outside the shelter, run them on their own tanks and pump as often as the crowd needs. During Red Flag Warnings we can hold units ready so the response is faster.
Can a restroom trailer go airside at the airport?
Yes, with the airport's escort and security rules. We plan every delivery and service visit around your escort schedule and badge requirements.
What is the difference between the 8-Station and the ADA +6?
The 8-Station unit has eight private stalls, each with a toilet, urinal and sink, and suits large crowds. The ADA +6 has a unisex accessible room with a built-in ramp, plus six standard stations. Many sites use one of each.
Can we move a unit as the construction phase changes?
Yes. We write moves into the order so a phase change only takes a call and a date. We pump the tank, move the unit and level it at the new spot.
Do you cover sites near the border at Otay Mesa?
Yes. We deliver to the South Bay and Otay Mesa. Border projects often have their own site rules and traffic windows, so send us those with your request.
How far ahead should a command book restroom trailers for an exercise?
A few weeks of notice lets us hold the right units and clear gate access. Shorter notice can work, so call even if the exercise is close. Standing terms set before the fiscal year make last-minute orders much easier.

San Diego restroom trailer guides for military, federal and emergency work

A laptop and paperwork on an office desk

What a base contracting office needs from a restroom vendor

Buying restroom trailers for a military site follows federal rules, and the vendor side can speed that up or slow it down. The Federal Acquisition Regulation sets the ground rules for most federal buying. Knowing what the contracting office will ask for saves days.

Registration comes first. Federal contracting offices need a vendor with an active SAM.gov registration, and the CAGE code and UEI tie the vendor to that record. Mavirus Group's registration is active. Ask us for both numbers, and we'll put them on the quote.

The scope comes next. Spell out the number of units, the dates, the location and the service schedule. Include any escort rules or restricted hours. A clear scope lets the contracting office compare quotes without guessing.

Insurance and site rules follow. Many installations require a certificate of insurance and a list of drivers and vehicles. Some require a safety plan for work on the installation. Tell us early, and we'll have each document ready before the order is placed.

Think about the full training year. Commands with regular exercises can set up an agreement that covers repeat orders. That lets a unit call for trailers without restarting the process each time.

Keep a record of service. Our techs log every pump-out and cleaning. When the invoice arrives, it matches a log your team can check.

Sizing restrooms for a multi-day field training exercise

A field exercise puts a crowd in a place with no buildings. Getting the restroom count right on day one keeps troops focused on training instead of lines.

Start with peak head count. Count everyone in the field at the busiest point, including support staff, observers and contractors. Use that number, not the average across the week.

Look at the daily rhythm. Restroom use spikes at wake-up, meals and shift changes. Units near the tent line handle the morning rush, and units near the dining area handle meals. Splitting units between those areas cuts lines at both.

Plan for access. The ADA +6 unit puts an accessible room with a ramp near the command post or medical area. Observers, visitors and anyone with an injury will use it.

Set the service rhythm. Exercises that run around the clock need pump-outs on a steady schedule, often at night when trucks can move freely. We set that schedule with your logistics staff before the first unit arrives.

Handwashing matters in the field. Our units have running water sinks, and we refill fresh water on every visit. Good washing cuts the spread of stomach bugs that can sideline a unit in a crowded camp.

Wildfire smoke rising over a chaparral ridge

Restroom plans for Santa Ana wind evacuations

Santa Ana wind fires move fast. The 2007 Witch Creek Fire led to the evacuation of about 500,000 people in San Diego County, It was part of the largest evacuation in California history up to that time. Shelters opened with little notice.

Shelters in schools, arenas and churches have restrooms built for normal use. When hundreds of evacuees stay overnight, those restrooms run short within hours. Trailers outside the building add capacity quickly.

Plan before fire season. Emergency planners can list likely shelter sites and mark a spot for trailers at each one. Look for level ground, a path to the door and room for a service truck. The county's ReadySanDiego program lists the steps families take, and shelter planning belongs alongside it.

Watch the warnings. When a Red Flag Warning goes up, call us to hold units. A trailer that is already hitched and waiting saves hours once a shelter opens.

Plan for everyone. Evacuees include older adults, people using wheelchairs and families with small children. An ADA +6 unit covers accessible needs, and private stalls give families room to help young kids.

Keep service going after the fire. Some evacuees can't go home for days or weeks. Set the pump-out schedule for the long stay and cut it back as people leave.

Power lines crossing dry hills

Keeping restrooms running through a power shutoff

Utilities in California may shut off power during high fire risk to keep lines from starting fires. In San Diego County, those shutoffs tend to come with Santa Ana winds. A site can lose power for a day or more even when no fire is nearby.

Restroom trailers handle this better than most buildings. Toilets and sinks run from onboard tanks, so the basic function keeps working. Lights, fans and air conditioning need power, and that's where planning comes in.

Know your zone. Utilities publish shutoff information and alerts. Check whether your site sits in an area that has been shut off before, and let us know when you order.

Plan backup power. A small generator can carry a 2-Station unit on one 20 amp circuit. Larger units need two circuits. We'll work out the power need with you so the generator is sized right.

Move service up. When a wind event is forecast, we can pump tanks ahead of time. That way a trailer starts the outage with an empty waste tank and a full fresh tank.

Check after the wind. High winds can shift a unit or damage steps. Our techs check leveling and entry stairs on the first visit after the event.

Shipyard cranes along the waterfront

Restroom placement on shipyard and pier projects

Waterfront work spreads crews along long piers and yards. The walk to a building restroom can eat a large share of every break. Placement on these sites takes more thought than on a normal lot.

Map the walk. Mark where crews work and where the nearest restroom is. If the walk runs more than a few minutes, a trailer closer to the work pays for itself in time saved.

Pick solid ground. Pier aprons and yard pavement are usually fine. Stay clear of crane paths, forklift lanes and edges where splash reaches. Your safety office will know the lanes to avoid.

Title 8 Section 1526 still applies on waterfront construction. Facilities must be clean, private and stocked, and nonwater-carriage toilets are allowed where a sewer isn't practical. Self-contained trailers fit piers well for that reason.

Plan for salt air. Metal parts wear faster near the water. Our techs check hinges, closers and stairs on every visit and replace parts before they fail.

Time service with shifts. Yards often run more than one shift. We service units between shifts, so crews never find a truck parked at the restroom door.
