Metal Building Permits: What You Need to Know Before You Buy

Do You Need a Permit?

The short answer is: probably. Most counties and municipalities require building permits for permanent structures, including metal garages, barns, workshops, and commercial buildings. Some jurisdictions also require permits for open carports, especially if they exceed a certain size (usually 200 square feet).

However, the specific requirements vary widely from one jurisdiction to the next. Some rural counties have minimal permitting requirements, while urban and suburban areas tend to have stricter rules.

How to Find Out

Contact your local building department (usually at the county or city level) and ask about the permit requirements for an accessory structure on your property. You will need to know:

• The type of building (carport, garage, barn, etc.)
• The size (width x length x height)
• The intended use (vehicle storage, workshop, agricultural, etc.)
• Whether the building will have electrical, plumbing, or concrete

What You Will Need for the Permit Application

Most permit applications require:

• Site plan: A drawing showing where the building will be placed on your property, including distances from property lines, other structures, and easements
• Engineering drawings: Certified structural drawings showing the building meets local wind and snow load requirements. We provide these with every order.
• Building specifications: Size, height, materials, roof style, and foundation type
• Permit fee: Typically $50-$500 depending on the building size and jurisdiction

Setback Requirements

Most jurisdictions have setback requirements — minimum distances between your building and your property lines, the street, other structures, and utility easements. Common setbacks are:

• Front: 25-50 feet from the street
• Side: 5-15 feet from the property line
• Rear: 10-25 feet from the rear property line

Setbacks vary by zoning designation (residential, agricultural, commercial) and by jurisdiction. Always verify your setbacks before ordering your building.

HOA Restrictions

If your property is in a homeowners association (HOA), check the covenants, conditions, and restrictions (CC&Rs) before ordering a metal building. Some HOAs restrict or prohibit metal structures, while others allow them with conditions (specific colors, styles, or placement).
