Do I need a permit for a 18×45 class a rv garage with workbench?
Almost always for 810+ sq ft enclosed buildings. Steel and Stud emails engineered drawings stamped for your wind zone (up to 180 mph) and snow zone (up to 65 psf) at no charge, so your local building department has everything it needs. Permit timing typically runs 2–6 weeks by jurisdiction.
How is a Steel and Stud class a rv garage with workbench different from a wood-frame build?

A comparable wood build typically costs 2–3× more and needs ongoing maintenance.

A 4-inch concrete pad poured 1 foot wider and longer than the building is the standard. Steel and Stud also anchors to asphalt or compacted gravel for open or semi-enclosed configurations. A pad-pour bundle is offered at checkout if you don't already have a slab.
