Questions about larger buildings.
Vinyl or metal at this scale?
Vinyl for standard residential use, longer warranty (15 vs 10 years), warmer aesthetic. Metal Imperial for wider drive-in (12 vs 10.5 ft), heavier-duty applications, or industrial aesthetic. See our comparison guide for the full decision tree.
Do I need a permit?
Yes for every option in this collection. Larger sizes (250+ sq ft) often require structural engineering documentation. Some jurisdictions require additional electrical and zoning approvals. Permitting is the customer's responsibility per our policy.
What foundation do I need?
4-inch concrete slab with rebar at minimum. 6-inch at the largest sizes per typical local code. Slab dimensions match the building footprint with a small overhang allowance.
DIY install or hire a contractor?
Most buyers hire contractors at this scale. 2-person professional crew finishes structural work in 2-4 days. DIY with two helpers is possible but takes 4-7 days and requires precision for the longer wall and roof runs.
What is the warranty?
Vinyl options: 15-year limited warranty. Imperial metal: 10-year warranty. Apex Pro 15x8: 15-year. Full details on our warranty page.
About DuraMax Garages and Larger Sheds
This collection brings together every DuraMax building at the garage and larger-shed scale - 12 products that share one trait: they all require permits regardless of jurisdiction, slab foundations, and substantial install effort.
The vinyl garages (seven sizes from 10.5x15.5 to 10.5x30.5) provide vehicle storage with double drive-in doors. 10.5 ft drive-in width fits standard cars, SUVs, and most pickups with workshop space along the back wall. The Imperial metal garages (four configurations - 12x20 and 12x26 in two color combinations each) provide wider 12 ft drive-in for trucks, tandem vehicles, or workshop-emphasis builds. The Apex Pro 15x8 vinyl shed is the widest shed in the line - 120 sq ft with two front doors plus two side windows, the architectural shed option at the larger scale.
For all 12 products, plan for: permit process (allow 2-8 weeks depending on jurisdiction), structural engineering documentation often required at 200+ sq ft, 4-inch concrete slab foundation at minimum (some jurisdictions require 6-inch at the largest sizes), electrical service from your main panel (most owners install sub-panels), and professional installation as the more common path at this scale (typical contractor cost: $1,500-$4,000 depending on size and region).
