Mobile Office Trailers in San Antonio

Government work keeps a surprising number of San Antonio trailers rented. Joint Base San Antonio spreads across Fort Sam Houston, Lackland and Randolph, and the construction on and around those bases never really stops. A contractor on base has to deal with gate access, vehicle checks and approved delivery windows, and the trailer needs to be there when the escort is.

Base work, medical work and the I-35 corridor

The South Texas Medical Center, up the road from downtown along Floyd Curl Drive, is the other constant. Hospitals and research buildings there are expanded and renovated in phases, and each phase needs a field office close to the work. Downtown has the hotels around the River Walk, the courthouse area and a steady string of apartment towers and conversions.

Out along I-35 northeast of the city, Schertz, Converse and Universal City have grown quickly, with distribution buildings and schools going up on former ranchland, plus strip centers to serve them. That corridor sits right next to Joint Base San Antonio-Randolph, which means some contractors serve both private and military jobs from the same yard. South of the city, the Toyota plant and the industrial ground around Port San Antonio draw a different crew of builders, and the Eagle Ford oil and gas fields to the south and southeast use trailers as field offices for drilling and pipeline crews.

What the yard asks first

Expect the address and the county up front. Bexar, Comal and Guadalupe counties handle things their own way, and some jobs sit right on the line. After that come the delivery date you want and how long the trailer stays, a headcount, and the power on site. If visitors or inspectors will come inside, say so. On a base or behind a gate, give the name of the person who can clear the truck.

Mention the ground, too. Hill Country limestone near the surface and clay in the flatter parts of the city are very different to set a trailer on.

The mix of buyers shapes the quotes you get. A contractor on a base project often wants a larger double-wide with a conference room, because there are meetings with the government's representative every week. A roofing company working storm damage in Schertz needs a small trailer for a month, and a developer in Converse wants a sales office for a subdivision that will take two years to sell out. Each of those is a different unit and a different lease, so say what yours is.

Restrooms deserve a mention. San Antonio sites without sewer access often use a trailer with a holding tank, or rent separate portable restrooms. If you want a restroom inside, the water and waste connections need to be planned ahead.

Heat, hail and wind

A trailer in San Antonio is cooled nine months of the year, so the air conditioner is a main selling point. Ask what size it is, and ask how much heat the walls and roof can keep out. Dark metal roofs on a trailer with no shade soak up the afternoon sun, and a reflective coating helps.

Hail is the weather people forget until it happens. A spring storm can dent a roof and break windows, and a trailer with covered glass fares better. Ask what the provider's policy is on storm damage, and who pays for it. Wind is a smaller issue than on the coast but is real on the open ground east of the city. Tie-downs are a good idea on any unit that stays more than a few weeks.

Rain, when it comes, comes hard. Flash flooding in low spots and along creek beds is common, and the Edwards Aquifer recharge area in the north and west of the city gets extra attention for runoff and fuel storage. If your site is near it, ask what applies before the trailer arrives.

Picking a provider

San Antonio is big and flat enough that distance matters. A provider on the northwest side may take longer to reach Converse than one with a yard on I-35. Ask where the yard is. Ask how many days between your call and a delivery, and whether the trailer is the exact one you saw in the photos. Ask who sets the steps and skirting, and whether the quote includes them.

Ask about pickup, too. At the end of a long job, the trailer needs to be unplugged, emptied and cleared, and a provider who charges a surprise cleaning fee should be asked about it before you sign, not after.

Most jobs run on a monthly lease. If the base work is going to go on for years, or if you run a dealership that needs a permanent second office, used trailers are sold as well.

Permits

A trailer parked for months on a job lot often raises a permit question, or at least a notice to the city. San Antonio, Schertz, Converse and Universal City have separate building departments, and a short job may be treated differently from a long one. Ask the department for your parcel. Property owners and owners associations sometimes have rules of their own for how a trailer looks from the road.

If you are near the base, ask the base contracting office about its own placement rules. They do not always match the city's.

One thing that surprises out-of-town contractors is how fast San Antonio grows outward. A site that was open ranch last year can be a paved lot this year, and a provider that has not been out there may not know the road to it. Send directions, and do not rely on a map alone.
