How to Build a Temporary Garage with Poly Tarps
When you need extra storage for your car, boat, or outdoor equipment but don’t want to invest in a permanent structure, a temporary garage made with poly tarps is a cost-effective and practical solution. Poly tarps are strong, versatile, and weather-resistant, making them an excellent material for creating a shelter that protects your valuables from rain, snow, UV rays, and debris.
With the right setup, you can construct a durable temporary garage that lasts for months—or even years—depending on how well it’s maintained. In this guide, we’ll walk through the steps of building one and share tips for choosing quality materials.
1. Plan the Size and Location of Your Garage
The first step in building a tarp garage is careful planning. Think about what you’ll be storing and how much space you need.
Measure your vehicle or equipment: Add at least 2–3 feet of clearance on each side for easy access.
Pick a level spot: A flat surface makes setup easier and prevents water from pooling.
Consider drainage: Avoid areas where rainwater collects.
Check local regulations: Some neighborhoods may have rules about temporary structures.
A well-chosen location ensures that your garage is functional, stable, and compliant with local guidelines.
2. Choose the Right Poly Tarp
Not all poly tarps are suited for outdoor structures. A lightweight tarp may be fine for short-term use, but for a garage, you’ll want something heavy-duty.
Look for these features:
Thickness: At least 10–12 mils for durability.
UV resistance: Protects against sun damage and extends the tarp’s lifespan.
Waterproof coating: Essential for keeping your belongings dry.
Reinforced edges and grommets: Provides strength for secure tie-downs.
Reliable tarp suppliers sell their products online, including through Amazon. There, you’ll find heavy-duty options with customer reviews and detailed descriptions, helping you pick the right size and quality for your project.
3. Build the Frame Structure
The frame is the backbone of your temporary garage. You can either buy a pre-made canopy frame or build one yourself with common materials.
DIY frame materials:
PVC pipes: Affordable and lightweight, great for small to medium shelters.
Galvanized steel pipes: Stronger and more durable, ideal for long-term use.
Wooden posts: Easy to source but may require extra maintenance.
Steps to build the frame:
Construct a rectangular base to outline the garage.
Add vertical supports at each corner and along the sides for stability.
Create a peaked or rounded roofline to allow water and snow to run off.
Secure all joints with connectors, screws, or heavy-duty brackets.
A strong frame ensures your garage withstands wind, rain, and seasonal weather changes.
4. Attach the Poly Tarp Cover
Once the frame is complete, it’s time to cover it with your poly tarp. This step requires careful tensioning to prevent sagging or tearing.
Drape the tarp evenly: Place it over the frame so that it covers both sides and extends to the ground.
Secure with bungee cords or rope: Thread them through the grommets and attach to the frame.
Reinforce stress points: Add extra ties at corners or high-wind areas.
Anchor the bottom: Use weights, sandbags, or ground stakes to keep the tarp from lifting.
Pro tip: Instead of covering the entire structure with one tarp, some builders prefer using two—one for the roof and another for the sides. This allows for easier replacement if one section wears out.
5. Maintain and Reinforce for Longevity
A poly tarp garage can last a long time if properly maintained. Regular upkeep keeps your belongings safe and the structure in good condition.
Inspect regularly: Check for rips, loose grommets, or sagging sections.
Tighten ropes and bungees: Wind and weather can loosen tie-downs over time.
Remove snow buildup: Use a broom or brush to prevent excessive weight on the tarp.
Replace worn tarps: Even heavy-duty poly tarps eventually wear out; replace them promptly to avoid leaks.
If you anticipate heavy use or severe weather, consider doubling up on tarps for extra strength.
Conclusion: Affordable Shelter Made Easy
Building a temporary garage with poly tarps is a smart and budget-friendly way to protect your vehicle, tools, or outdoor equipment. With a well-planned site, a sturdy frame, a quality tarp, and regular maintenance, you’ll have a shelter that shields your belongings from the elements year-round.
When shopping for poly tarps, choose reputable suppliers that sell durable, heavy-duty options online. Several trusted sellers on Amazon provide a wide range of sizes, colors, and thicknesses, along with reviews to help you find the right product. With the right setup, your tarp garage can be a long-lasting solution for affordable outdoor storage.
