Equipment and RV storage buildings in San Antonio, Texas
An equipment storage building is a steel frame over your machinery: open on the sides to cover the most ground per dollar, or closed in where the contents need walls and a lock. An RV storage building is the same frame, built tall and deep enough for a coach.
One independent metal building contractor puts a price on it and builds it.

Lot picked out? Each request goes to one independent contractor, whose call it is which jobs to accept.
Open sides or closed walls?
Start with what you are keeping the weather off. Sun, hail and rain call for an open-sided cover: columns, a roof, and as many bays as the ground holds, at the lowest cost per square foot on this site. Theft, dust, and anything with upholstery or wiring call for walls and a door. Most working places land in between, three sides closed and the open side turned away from the weather.
Size it off the longest, tallest thing you own, loaded. Doors are framed openings engineered into the order, so settle the door schedule before the plant punches the steel.
What goes under the bays: gravel, caliche or concrete
Not every bay needs concrete, and on a ranch most do not. Compacted gravel or caliche drains and carries tracked equipment for less. Concrete is for a machine you jack up, a wash bay, or a coach parked year-round. Split the floor where the uses split.
The pad is where these buildings fail quietly: it has to be built up, compacted and drained so water leaves instead of pooling at the column bases. The dirt changes by county: Atascosa County's Hindes soils formed over caliche beds, and the unit under about 25 percent of that county is limited by shrinking and swelling, corrosivity to uncoated steel and low soil strength (Soil Survey of Atascosa County, Texas, USDA Soil Conservation Service, 1980, checked 2026-09-13). More on the pad and site prep sheet.

An engineer on a ranch storage building?
Often not, which is rare for a building this size. When nobody holds out to offer engineering services to the public, Occupations Code 1001.056 lets a private building put only to farm, ranch or agricultural use, or to storing raw agricultural commodities, skip the state engineering chapter. It lets a building skip it too when the building is one story, 5,000 square feet or less, with no clear span wider than 24 feet across its narrow side; where one that size spans farther, only the roof framing has to be engineered or pre-engineered.
Mind the word only. A building that also holds a contractor fleet, a rented bay or business stock is outside it, and a county reviewer, a lender or the manufacturer can ask for a sealed foundation plan regardless.

Permits for a storage building past the city limits
The address decides, and a county's power is narrow. Local Government Code Chapter 233 leaves a county with no general commercial building code. The one power that can reach a building like this is a fire code, which only a county of more than 250,000 people, or one bordering a county that size, may adopt, and which reaches only commercial establishments, public buildings, and multifamily residential dwellings of at least four units.
In unincorporated Bexar County the Fire Marshal Office at 210-335-0300 decides when structures not for single-family dwelling use need building permits, and that permit reaches site clearing, so clearing gets permitted before the pad is cut. The other six answer for themselves: Karnes County posts special projects, septic, and road and bridge permits and names no building permit on any page checked (Karnes County permitting pages, checked 2026-09-13). That describes its site, not a tract with no rules; confirm at 830-780-3511. County by county: the county index.

The aquifer plan and stormwater filings that hold up the dirt work
On the north side of Bexar and Medina counties, clearing falls inside the aquifer rule, not ahead of it. On the recharge, transition or contributing zone, construction cannot start until TCEQ approves an Edwards Aquifer protection plan. On the recharge zone that plan covers buildings, roads, clearing and digging, so the pad and the ranch road are in it; the contributing zone trips at five disturbed acres. Only parts are regulated, and the TCEQ map viewer settles a tract. Budget the time: administrative review of up to 30 days, followed by 90 calendar days of technical review, and no work before approval issues.
Stormwater goes by acreage, not zone, and a long building with its drive and turnaround passes an acre quickly. An acre or more disturbed, with runoff to surface water in the state, needs coverage under the TCEQ construction general permit and a pollution prevention plan up front.
One acre to under five: no Notice of Intent; a signed site notice posted, with a copy to the storm sewer operator two days before work begins.
Five acres or more: a Notice of Intent through STEERS first ($225 online, $325 on paper), then a Notice of Termination within 30 days of stabilization.
Neither one frees a lot over the aquifer: no construction until TCEQ approves the protection plan.

A drive onto a county road needs its own permit
Equipment shows up on a trailer, so settle the access before placing the building. The table sorts out who permits the drive depending on the road it meets.
| Road the drive meets | Permitting office | What the office posts |
|---|---|---|
| State highway | TxDOT's local district office (Form 1058) | The right of way stays untouched until the permit is executed; TxDOT also gets 24 hours notice. The San Antonio district, 210-615-1110, covers six of these seven counties; Karnes belongs to another. |
| County road, Wilson County | Wilson County Permitting and Development, 830-393-8357, under the PIPROW permit | $750.00 for a commercial drive from 24 to 100 feet; $250.00 for a residential and agriculture drive from 12 to 24 feet; $100.00 for a temporary or construction drive, credited toward the permanent one. |
| County road, Frio County | Frio County Road and Bridge, 830-505-7402 | No driveway or culvert permit on the county site; road crossings are priced only for utilities and pipelines. Call before cutting in. |

Rented bays, a restroom, and the rules that follow
Both change things. Any project with $50,000 or more in total estimated construction cost must be registered with TDLR, with the construction documents going to a registered accessibility specialist under Administrative Rule 68.50, and Government Code 469.003 reaches a building that meets the federal Americans with Disabilities Act definition of a public accommodation or a commercial facility. Take rented bays to the design professional first. The standards stay out of private residences, which is where your own equipment at your own house sits.
A restroom, an office or a wash bay turns septic into a permit, not just a plumbing line. The rules count any building that is not a single-family home or a duplex as commercial, and 30 TAC 285.5 requires an engineer or sanitarian to seal the planning materials for new construction on the Edwards Aquifer recharge zone. The 10 acre exemption is written for one single family dwelling alone on its tract, so it does not carry over. Each county here has its own authorized agent.

Who needs this building, and what to get on paper
It suits an owner with more iron than roof: a rancher with implements and trailers baking in the sun, a contractor parking a fleet, a family with a coach on acreage. It is the wrong pick in three cases. One vehicle at a house in town calls for RV and detached garages. A building you work inside is a shop. And where posts suit the ground and budget better than red iron, price it against post-frame and pole barn buildings.
Two answers move this price more than square footage: how many sides close, and what floor each bay gets. Put both answers in the request, and it reaches a single independent metal building contractor, whose call it is which jobs to accept. Texas licenses no home builder or general contractor, so the license numbers worth asking for belong to the electrician and the plumber.
Get on paper: bay width, clear height and how many sides close; the door schedule; the floor in each bay; who cuts and compacts the pad; who applies for the driveway and building permits and any aquifer or stormwater filing. No company serving this area posts a price, so the quote comes off your bay count, your floors and the ground under the pad. The build order: the start-to-finish San Antonio guide.

What owners ask
Is a permit needed for an RV storage building in Bexar County, TX?
Outside city limits, call the Bexar County Fire Marshal Office at 210-335-0300 before ordering steel. In unincorporated Bexar County that office decides when structures or areas not for single-family dwelling use need building permits (the county counts a structure of three or fewer dwelling units as single-family), and the permit reaches site clearing as well as the build. The county gets 30 days to issue or deny; the permit then runs 180 days. Checked at bexar.org, 2026-09-13.
Is an engineer needed on a Texas ranch equipment building?
Often not. When nobody holds out to offer engineering services to the public, Occupations Code 1001.056 lets a private building put only to farm, ranch or agricultural use, or to storing raw agricultural commodities, skip the state engineering chapter. It lets a building skip it too when the building is one story, 5,000 square feet or less, with no clear span wider than 24 feet across its narrow side; where one that size spans farther, only the roof framing has to be engineered or pre-engineered. A building holding a business fleet or rented bays falls outside the exemption. Checked at Texas Legislature Online, 2026-09-13.
Must an open-sided storage building have a concrete floor?
That is a use call, not a rule this site can point to. Gravel or caliche drains and carries tracked equipment; concrete is for a machine you jack up, a wash bay or a parked coach. Either way the frame sits on anchor bolts set to the column reactions, so the footings get designed whatever the floor is. Over the Edwards Aquifer, concrete counts: TCEQ counts rooftops, driveways, concrete pads, sheds and sidewalks as impervious cover, and one case where a homeowner may not need an individual protection plan is keeping that cover at or under 20 percent of the lot. Checked at tceq.texas.gov, 2026-09-13.
In Bexar or Medina County, TX, does the aquifer plan cover clearing and the pad?
On the recharge zone it does, so it comes ahead of the dirt work. On the recharge, transition or contributing zone, construction cannot start until TCEQ approves an Edwards Aquifer protection plan, and on the recharge zone the plan covers buildings, roads, clearing, digging and anything else that changes how the ground takes in recharge. On the contributing zone, a plan comes into it only when the work disturbs five acres or more or the lot belongs to a wider plan for development or sale. Only parts of the aquifer are regulated.
