Check These Before You Enclose a Carport
- Permits and HOA rules: You do not necessarily need a permit for removable options like curtains, tarps, and screens, but you will need a permit for metal panels or garage conversion. Confirm from your local building department and HOA first before you start any work.
- Wind Resistance: Make sure your carport frame and anchors are strong enough to handle extra pressure because adding walls can make it catch the wind like a sail. And if necessary, you can add anchors for extra stability.
- Ventilation and moisture: An enclosed carport can trap moisture and cause condensation. So ensure you leave a small gap at the top or bottom, or install vents to keep the space dry and protect your car and other stored items.
- Exhaust: Exhaust fumes can be dangerous; do not run a car engine or generator in a closed carport. Make sure the area is open before you start your vehicle.
- Access: Think about how you will get in and out of the space. You could add a zipper door, a roll-up flap, or leave one end open for easy access.
Idea 1: Hang Tarps
To cover the side of a carport, you can use poly or canvas tarps, as they are the cheapest way to do that. Whether you need protection during a storm, through the winter, or while working on a short-term project, they remain a practical option for temporary use.

Common Questions About Enclosing a Carport
Can you enclose an existing carport?
Yes. You can enclose most carports by attaching curtains, screens, or wall panels to the existing post frame. Before you install solid walls, make sure the structure and its anchors can support the added wind pressure. Check local building rules to confirm if a permit is required.
What's the cheapest way to enclose a carport?
Tarps are usually the least expensive option, costing around $30 to $120 per side, but they can only last for one or two years. But for customized vinyl curtains, they provide a better fit and last for many years. If you want to keep insects out, screen walls are an affordable choice.
What is the average cost of enclosing a carport?
From $100 for a basic tarp to $40,000 for a complete garage conversion. Removable curtains, screens, and polycarbonate panels can cost from a few hundred to several thousand dollars per side. Steel with panels typically costs $800 to $2,500 per side.
How do I temporarily enclose a carport?
You can use tarps, removable side curtains, or a canopy sidewall kit. These are usually attached with hooks, snaps, or elastic cords, making them easy to remove without tools. You can also roll up vinyl curtains and secure them to leave the side open.
Do I need a permit to enclose an existing carport?
Yes, you most times need a permit for permanent walls, steel panels, or a full garage conversion. Temporary options, such as tarps, screens, and removable curtains, may not need one. Requirements differ by location and HOA, so confirm with your local building department before you start work.
How do I cover the sides of a carport?
You can attach different materials between the carport posts. Tarps and vinyl curtains are suitable for temporary coverage, while screens help keep insects out. Polycarbonate sheets allow daylight while blocking rain, and steel panels provide a solid barrier against bad weather and unwanted access. Your choice depends on what you want to protect against.
