Carport Buying Guide: Materials, Sizes, and Permits

A carport is a practical and affordable way to protect your vehicle from sun, rain, hail, and snow. Unlike a garage, it is an open-sided structure with a roof supported by posts, so it costs less and takes up less space. But buying a carport involves several important decisions. You need to choose the right material, pick a size that fits your vehicle and property, and understand local permit rules. This guide walks you through each step so you can make a well-informed purchase.

What Is a Carport?

A carport is a covered structure designed to shelter vehicles. It typically has a roof and support columns but no walls or doors. Carports can be attached to a house or stand alone. They range from simple fabric canopies to permanent metal or wood structures. The main purpose is protection from the elements while keeping the cost and footprint lower than a traditional garage.

Key Factors to Consider Before Buying

Before you shop, think about how you will use the carport and what conditions it must withstand.

• Purpose: Will it cover a daily driver, a classic car, a boat, or an RV? Different vehicles need different sizes and heights.
• Climate: Areas with heavy snow, strong winds, or intense sun require sturdier materials and proper anchoring.
• Space: Measure your available area, including clearance for opening doors and walking around.
• Budget: Consider upfront cost, installation, permits, and long-term maintenance.
• Local rules: Check zoning, building codes, and homeowners association (HOA) requirements before you buy.

Carport Materials: Pros and Cons

The material you choose affects durability, appearance, maintenance, and price. Here is a breakdown of the most common options.

Steel

Steel carports are strong, durable, and resistant to rot, insects, and fire. They are often galvanized or powder-coated to prevent rust. Steel can handle heavy snow loads and strong winds when properly anchored. They require little maintenance. However, steel can be noisy during rain or hail, and it may dent from large impacts. Cost is moderate to high.

Aluminum

Aluminum carports are lightweight, rust-proof, and easy to install. They work well in mild climates and coastal areas where salt air is a concern. Aluminum is not as strong as steel, so it may not be suitable for heavy snow or extreme wind. The upfront cost is often higher than steel.

Wood

Wood carports offer a classic, natural look and can be customized with stains or paints. They are relatively easy to repair. However, wood requires regular maintenance, such as sealing or staining every few years. It can rot, warp, or attract insects. Wood is also susceptible to fire. Cost varies widely depending on the type of wood and design.

Vinyl

Vinyl carports are low maintenance and resist rot, rust, and insects. They are easy to clean and come in various colors. Vinyl can become brittle in extreme cold and may fade over time. Design options are more limited than wood or metal. Cost is generally moderate.

Fabric and Canopy

Fabric carports are portable, affordable, and quick to set up. They are a good choice for temporary protection or light use. However, the fabric can tear, fade, or sag over time, and the frame may not withstand severe weather. Expect to replace the cover every few years. These are the least expensive option.

Choosing the Right Carport Size

Size is critical. A carport that is too small can make it hard to park and open doors. One that is too large may waste space or violate local rules.

Standard Carport Sizes

• Single car: 12 feet wide by 20 to 24 feet long.
• Two cars: 20 to 24 feet wide by 20 to 24 feet long.
• RV or large truck: 12 to 14 feet wide by 30 to 40 feet long.
• Extra height: Add 1 to 2 feet above your vehicle’s height for clearance.

These are general guidelines. Always measure your specific vehicle and add space for doors, mirrors, and walking room.

Measuring Your Space

1. Measure the length, width, and height of your vehicle.
2. Add at least 2 to 3 feet on each side for door opening and movement.
3. Add 1 to 2 feet of height clearance above the roof.
4. Check for obstacles like trees, utility lines, or fences.
5. Confirm property lines and required setbacks from your local building department.

Carport Permits and Building Codes

Many areas regulate carports as permanent structures. Ignoring permit rules can lead to fines or forced removal.

When You Need a Permit

Permit requirements vary by location. In general, you may need a permit if the carport is:

• Attached to your home.
• Larger than a certain square footage (often 100 to 200 square feet).
• Taller than a certain height.
• Located within a certain distance of property lines.
• Permanent (concrete foundation or anchored to the ground).

Some areas allow small, temporary carports without a permit. Always check with your local building or planning department before purchasing.

How to Apply for a Permit

1. Contact your local building department to ask about requirements.
2. Submit a site plan showing the carport location, dimensions, and distance from property lines.
3. Provide details on materials, roof load, and wind resistance.
4. Pay any required fees.
5. Obtain approval before installation. If you have an HOA, get their approval as well.

Permits add time and cost, but they ensure your carport is safe and legal.

Installation Options: DIY vs Professional

You can install some carports yourself, especially kit models. DIY saves on labor but requires time, tools, and physical effort. Professional installation is faster and ensures proper anchoring and code compliance. For large or permanent structures, hiring a licensed and insured installer is often recommended.

Cost Considerations

Carport costs depend on several factors:

• Materials: Fabric is cheapest; steel, aluminum, vinyl, and wood vary.
• Size: Larger carports cost more.
• Installation: DIY saves money but takes time; professional adds labor costs.
• Permits: Fees vary by location and project size.
• Foundation: Concrete slab or ground anchors add cost.
• Maintenance: Wood requires more upkeep than metal or vinyl.

Maintenance Tips

• Inspect the roof and fasteners twice a year.
• Clean leaves and debris from the roof.
• Check for rust, rot, or damage and repair promptly.
• Tighten bolts and screws as needed.
• Touch up paint or sealant to extend life.
• Remove heavy snow to prevent collapse.

Conclusion

Buying a carport is a practical investment that protects your vehicle and extends its life. The key is to match the material to your climate, choose a size that fits your vehicle and space, and follow local permit rules. By considering these factors, you can select a carport that meets your needs without surprises. For more helpful guides on home and lifestyle topics, explore other articles on our site.
