What Size Carport Can You Build Without A Permit

If you wish to build a metal carport and don’t know where to begin, start by figuring out your needs and applying for a permit. It is extremely important to navigate through local building codes and regulations to avoid any issues during or after installation. Across the US, permit requirements are different, and understanding these rules will help you in significantly saving time, effort, and money, along with preventing legal issues.

So, let’s dive in to see if you can build a carport without a permit, and if yes, then up to what size.

What is the Purpose of a Building Permit?

Even though they are simple roof-only structures, carports are considered to be construction projects. A building permit is an official document issued by the local government authorities, allowing you to install a structure.

These permits are often issued to ensure that your carports meet certain safety standards, setback requirements, zoning laws, building codes, height restrictions, and minimal local climate requirements.

It is like a seal of approval for your carport, allowing you to ensure that the structure:

• Offers structural safety
• Provides better property value
• Avoids legal penalties
• Complies with zoning laws
• Facilitates insurance coverage

What Carport Dimensions Will Not Require a Permit?

The permit requirements for carports significantly vary across America, as the local building codes and zoning laws determine the necessity of a permit depending on a range of factors, including dimensions.

While there is no universal minimum size that mandates a permit across the country, every jurisdiction has established specific thresholds.

In most states, a permit is typically required for structures exceeding 200 square feet. However, it can be lower or higher, depending on local regulations. For instance, some states like California exempt detached accessory dwelling units up to 120 square feet. Whereas, cities like Snohomish County in Washington can exempt structures up to 400 square feet under specific conditions.

Here is a list of a few states and their minimum permit exemptions based on size:

Speaking of height restrictions, buildings under 9 feet are usually exempt from permit requirements in urban areas, and those under 11 feet are essentially exempt in rural regions.

Factors Affecting the Permit Requirements

While size restrictions do affect permit requirements, there are a multitude of other reasons why you might require a permit to build or install a carport. Not just the requirement of a permit, the fee payment will also be dependent on these factors:

• Location: Depending on where you live, a big city, a small suburb, or the countryside, the local building codes and zoning requirements are supposed to vary. The zoning laws implemented in your region will decide your minimal permit requirements. Rural areas are likely to see more exemptions than bustling cities.
• Foundation: The type of foundation you install is also likely to affect your permit requirements. For instance, level bases or temporary foundations might not require a permit. However, concrete or permanent foundations are more likely to require additional permits.
• Setback requirements: It refers to the distance of your structure from property lines and other structures, as well as the roads and sidewalks. It is meant to ensure that there is enough space for emergency access as well as maintenance. Not only that, it will also reduce property conflict in the neighborhood. If you wish to build a carport without a permit, then setback requirements are also likely to influence size limitations.
• Intended use: The purpose of installing the carport is going to affect permit requirements, too. Residential carports might face fewer restrictions than those meant for commercial or industrial usage.
• Height: Height clearance is also a critical factor, as many districts impose height restrictions on permit requirements. There are other restrictions pertaining to height, too. For instance, if you are installing a carport within a historic district, there might be restrictions to prevent view obstruction.
• Regional climate conditions: Areas that are prone to adverse weather conditions like heavy snowfall, intense rainfall, tornadoes, hurricanes, or high wind speeds enforce stricter building codes and specific requirements to maintain the structure’s integrity.

What Happens if I Build a Carport Without a Permit?

You can be tempted to bypass the permits in order to save time, money, and effort. However, it isn’t advisable as constructing a metal carport structure without a permit would have severe consequences. Lack of proper authorization can lead to the following issues:

• Legal: Non-compliance with the local building codes can lead to hefty fines as well as legal action against you.
• Resale: Unpermitted carports will hamper the resale of your property and complicate the process by deterring buyers.
• Insurance: Any damage that occurred to the carport, which has been built without a proper permit, will not be covered by insurance companies.
• Safety: Not following permit requirements may cause structural issues in the carport, possibly endangering your life, property, and even your neighbor’s property.
• Remodel: Any expansions or renovations on your unauthorized carport might not be possible without first seeking a permit for the installation.
• Demolition: In case your carport goes against permit requirements, it is likely to be deemed illegal, leading to dismantling and removal. This will not just result in the demolition of the structure but also incur additional tear-down costs.

How to Find Out if You Need a Permit?

Different cities, states, and counties follow different rules and have varied requirements. As they are responsible for issuing a permit, contacting your local government and speaking regarding permit requirements is the best way to find out whether you need one.
