Steel Buildings in Maryland, From a Maryland Builder
Most steel building websites ship a kit from three states away and wish you luck with the county. We're the other kind: Sonny's Renovations is a Maryland general contractor (MHIC #109770) — we design, permit, and build steel buildings across the state, and the 3D designer prices your exact building instantly.

What Maryland specifically requires
- Snow loads: 25–30 psf ground snow across most of the state, 40+ in Garrett County — the frame must be engineered for YOUR county, which is why out-of-state "special" kits get rejected at permit.
- Permits: every MD county requires permits for buildings over 200–256 sq ft (varies); stamped engineered drawings are standard — our kits include them.
- Ag exemptions: bona-fide farm buildings get streamlined review in most counties, but "ag" is about use, not building type — a shop with a car lift doesn't qualify.
