What the 24×30 estimate includes — and what it doesn't
Most price pages won't tell you this. The slab alone can add a third again on top of the building, so here's the honest breakdown.
Included in the installed range
- The building — frame, roof and wall panels, trim, fasteners
- Engineering for Harris County's loads — 134 mph design wind
- Stamped drawings for your permit application
- Delivery to your prepared site
- Professional erection on a level, ready pad
- Anchors for the slab or ground type specified
Not included — budget separately
| Item | Typical cost |

Site prep — clearing, grading, and getting a truck to the pad — is the other variable we can't price for you. A level, accessible site is what keeps an install to a single day; a sloped or tight one is where surprise costs come from.

What drives the price in Harris County
A 24×30 building (720 sq ft) is in the garage-and-workshop range — big enough for vehicles, a home shop, hobby space, or storage, small enough to go up fast on a simple slab. It's the most common size for residential buyers. In Harris County, the design loads above — not just the size — decide where in the range your price lands.
Harris County's 134 mph design wind speed is in the elevated-inland-coast band. This meaningfully changes the steel package: heavier columns, closer fastener spacing, and often rod-and-cable or portal bracing. Any reputable supplier will engineer to 134 mph for this county, and the price band on this page already reflects that added steel.
Foundation & slab in Harris County
Steel is only half the job — the concrete under it is the other half. The Houston metro sits on expansive Beaumont and Lissie clays that swell and shrink with moisture. A properly designed slab — often post-tensioned or with a stiffened edge and moisture control — is what keeps a metal building square over time. Don't cut the foundation to save money here. The slab range shown in the estimator is a Texas-typical figure; your final number depends on a soils report and the local ready-mix price.
Harris County is Seismic Design Category A. Like nearly all of Texas, seismic loads do not govern a metal building's design here — wind is the controlling force, not earthquakes — so seismic adds nothing to the price band.
Permits in Harris County
For a metal building in Harris County, permitting typically runs through the Harris County Engineering Dept — Permits Office (713-274-3232). Requirements vary by whether you're inside a city limit, in the ETJ, or unincorporated, and most departments want the supplier's engineered, stamped drawings before they'll issue. Confirm current fees and setbacks with the office directly — we verify these links but rules change.

- Why does the price change by county?
- Steel is engineered to local building loads. A county's design wind speed, snow load, seismic category, and — on the coast — TDI windstorm certification all change how much steel and engineering the building needs. That's why Harris County has its own price band instead of one statewide number.
- Do I need a permit for a metal building in Harris County?
- Usually yes. Permitting typically runs through the Harris County Engineering Dept — Permits Office, and most departments require the supplier's engineered, stamped drawings. Requirements differ inside city limits versus unincorporated areas — confirm with the office before ordering.
