20×30 Metal Storage & Garage Overview
A 20×30 metal building delivers 600 sq ft of usable space — enough for a single-car garage with extra storage in South Carolina.

FAQ — 20×30 Metal Buildings in South Carolina
How much does a 20×30 metal garage with storage cost in South Carolina?

How many vehicles fit in a 20×30 metal garage?
A 20×30 fits 1 vehicle. At 600 sq ft, you also have room for a workbench or storage shelving along the walls. It’s one of the most practical sizes for homeowners who want a functional garage without oversized footprint.
Do I need a permit for a 20×30 building in South Carolina?
Permit requirements vary across South Carolina’s 46 counties. Structures over a certain threshold (commonly 144 or 200 sq ft) typically require a permit. At 600 sq ft, a 20×30 will almost certainly require one in most SC jurisdictions. Bull Buildings provides SC-licensed engineer-stamped drawings for all 46 South Carolina counties.
What roof style should I choose for a 20×30 in South Carolina?
A vertical roof is essential for South Carolina, especially in coastal counties. Many SC coastal counties require 140 mph wind-rated structures — ask your specialist about your location’s requirements. For a 20×30, the vertical roof also has the advantage of being the most durable long-term option — the panels run vertically so water and debris shed completely off the edge.
How long does delivery and installation take in South Carolina?
Most 20×30 orders in South Carolina ship and install within 4–8 weeks from site picture confirmation. We deliver and install across Charleston, Columbia, Greenville, Myrtle Beach, and all 46 SC counties. We’ll give you a specific delivery window estimate when you place your order.
