Learn the key considerations and options available when selecting an 18×20 metal garage to suit your storage needs and preferences.
Key takeaways:
- 18×20 dimensions ideal for 2 vehicles and storage/work space
- Consider concrete, gravel, or pier foundation options
- Pricing factors: material quality, customization, installation
- Estimated cost range: ,000 to ,000
- Ensure compliance with local building codes and regulations
X20 Garage Dimensions
An 18×20 garage provides a total of 360 square feet, ideal for housing two standard vehicles with additional space for storage or work area. The dimensions offer a comfortable clearance for doors and walking space around the vehicles, which is particularly beneficial when opening car doors or navigating around the perimeter with tools or equipment.
To visualize, an average parking space is approximately 9×18 feet. This garage’s width equals the length of two parking spaces side by side, with an added two feet to reduce the risk of dings and scratches when opening vehicle doors. The depth comfortably accommodates most cars and trucks, as well as providing extra room for items like lawnmowers, bikes, or workbenches.
When considering height, it’s important to account for storage and usage. A standard garage door is 7 to 8 feet high, which fits well within the typical garage height of 8 to 12 feet. This space allows for not just vehicle storage but also the potential for overhead shelving or even a loft space for additional storage or a small office, given the structural support is in place.
Lastly, the 18-foot width is beneficial when considering the addition of windows or walk-in doors alongside the primary garage door, as it allows ample wall space for such installations without compromising the structural integrity of the building.
Foundation Options for 18×20 Garages
Selecting the appropriate foundation is crucial for the structural integrity and longevity of a 18×20 garage. Concrete slabs are the most common and robust option, providing a flat, stable surface that supports the weight of the garage and its contents. The thickness of the slab should be at least 4 inches for adequate support, but may need to be greater depending on local building codes and the intended use of the garage.
For those seeking a less permanent solution or where concrete is not feasible, a gravel foundation may suffice. It is essential for the gravel to be properly leveled and compacted to prevent shifting and settling. A frame of pressure-treated lumber often outlines the gravel base, keeping the stone in place and providing a perimeter to anchor the garage.
Additionally, some prefabricated metal garage kits may allow for pier foundations, where concrete footings are placed below the frost line, and metal posts or piers support the structure. This method is less common for garages but can be advantageous in certain circumstances where elevation or drainage is a concern.
It’s important to consult with a local contractor or building authority to determine the most suitable foundation type for your particular location, considering factors such as climate, soil condition, and the topography of the land. Proper foundation choice and installation are vital to prevent future issues such as cracking, shifting, and water damage.
Price Breakdown of 18×20 Metal Garage
When evaluating the costs associated with a metal garage of this size, the price ranges significantly based on factors such as materials, customization, and installation. Here are some aspects that typically influence the final price:
Material Quality – The gauge of steel, a measure of its thickness and thus, durability, impacts cost. Higher gauge steel typically entails a higher price, but offers better longevity and strength.
Roof Style – A regular roof is most affordable; however, an A-frame or vertical roof, while more expensive, can provide added durability and are recommended in areas with heavy snowfall or high winds.
Customization – Adding windows, walk-in doors, or insulation can personalize your garage but will also contribute to a higher overall cost.
Delivery and Installation – Some suppliers include these services in the overall package, while others charge extra. Check if a turnkey installation is offered.
Local Building Requirements – Compliance with local building codes may necessitate additional structural features, affecting the overall expense.
Accessory and Finish Options – Opting for gutters, downspouts, trim, and other finishes will influence the final price tag.
Knowing these cost factors aids in setting a realistic budget and makes it more manageable to tailor your project to your financial and functional requirements. It’s crucial to request detailed quotes from multiple suppliers to understand better and compare the potential costs.
Estimated Cost for Fully Installed 18×20 Metal Garage
Determining the estimated cost for a fully installed 18×20 metal garage involves considering various factors, including materials, labor, and any additional features or customization.
Materials represent a significant portion of the overall price, with metal panels, framing, fasteners, and roofing components being the primary materials needed. These can vary in cost depending on the quality and type of materials selected.
Labor costs depend on the complexity of the installation, the contractor’s rates, and geographical location. It is essential to get multiple quotes to ensure competitive pricing.
Customization options such as windows, doors, insulation, interior finishing, and exterior treatments can also affect the total cost. Each addition must be calculated separately to get an accurate estimate.
Accessory structures like lean-tos, overhangs, or attached workspaces will further influence the final price.
Local building codes may require specific features for compliance which can add to the expense. It is crucial to include permit costs and any necessary inspections in the budget.
On average, the cost for a fully installed 18×20 metal garage ranges from $5,000 to $15,000. However, quotations from a certified installer will provide the most accurate cost assessment tailored to individual specifications and location.
Regional Code and Regulation Compliance
Ensuring compliance with local building codes and regulations is a critical step when installing a metal garage. These regulations govern aspects such as structural integrity, zoning, and safety standards specific to the area where the garage will be constructed.
It’s essential to obtain the necessary building permits before construction begins. Permit requirements vary by location, and failing to secure them could lead to fines or the need to dismantle the structure.
Zoning laws dictate the permissible uses for your garage, including size, placement, and sometimes even color or material. These are in place to maintain a community’s aesthetics and functionality.
Structural codes ensure that the garage can withstand local weather conditions such as heavy snow, high winds, or seismic activity. Adherence to these codes is paramount for the safety and longevity of the structure.
Fire codes may influence materials and design features, such as the installation of fire-rated panels or specific distances from other structures.
Accessibility guidelines may come into play, especially if the garage is intended for commercial use. Compliance with the Americans with Disabilities Act (ADA) ensures that everyone has adequate access.
Engaging local experts or building authorities early in the planning process can provide guidance and alleviate potential issues before they arise. These professionals understand local codes and can provide insights into best practices for ensuring a smooth and compliant construction process.
