Understanding Building Permits

Building permits are official approvals issued by the local government that ensure your construction project complies with local codes and regulations. They’re necessary for a wide range of residential projects, including new homes, home additions, remodels, and certain accessory structures. Notably, irregularly shaped decks or rectangular decks over 600 square feet, over 14 feet in width, or over 30 inches above grade require a plan review before a permit is issued.

There may be different types of regulations based on the different types of decks and the materials used.

The Role of Building Permits

Building permits play a crucial role in ensuring safety. They certify that your deck complies with structural safety standards and zoning laws, safeguarding future property owners. Permits also ensure that contractors carry out their work responsibly, maintaining the quality and value of your home.

The Building Permit Application Process

Applying for a building permit involves submitting detailed plans and specifications of your project for review. Although the deck cost can vary, investing in a permit can save you from future legal and financial headaches. In Peoria, residential plan review typically takes 2-3 days once complete code-compliant information is received.

Instances Where Permits Are Not Required

Certain decks do not require a plan review. Freestanding and attached decks, as well as rectangular decks that are 600 sq. ft. or smaller with a maximum width of 14 feet and a maximum height of 30 inches above grade, generally can be issued a permit the same day at the permit counter, provided all setback, location, and size requirements are met.

Risks of Building Without a Permit

Building without a permit can lead to safety hazards, fines, and legal issues. Unpermitted work could fail to meet safety standards, posing a risk to you and future homeowners. Financial and legal consequences can include fines, mandatory demolition, and complications when selling the property.

Consequences of Unpermitted Work

If discovered, unpermitted work can lead to immediate consequences like fines and potential demolition orders. Future implications include difficulty selling your property and possible issues with insurance claims.

Getting a Retroactive Permit

Obtaining a permit after the work has been done is challenging and costly. It usually involves a thorough inspection, and in some cases, parts of the deck may need to be dismantled for the inspection.

Professional Vs DIY Deck Building

As a professional, I ensure permit compliance for all my projects. However, if you’re taking the DIY route, it’s crucial to familiarize yourself with local codes and regulations. Remember, ignorance of the law is not a defence. If you’re opting to build the deck yourself, we’ve included a detailed PDF guide below.

Site Plan Requirements

Every permit application in Peoria requires a site plan. You can use Peoria County’s GIS map to create a site plan by printing an aerial view of your property. This helps the planning department to visualize your project and its impact on your property.

Special Regulations for Decks Associated with Swimming Pools

For those planning to add a swimming pool to their deck, Peoria regulations require a barrier for safety reasons. If your deck will serve as this barrier, your deck permit must be issued concurrently with your pool permit. Be prepared to submit a building permit application along with your pool permit application.


Building a deck is an exciting home improvement project, but it’s crucial to adhere to local regulations and obtain the necessary permits before you start. Doing so ensures the safety of your deck and adds value to your property.

Whether you’re a professional contractor or a DIY homeowner, understanding the specifics about building permits, especially in Peoria, IL, can make your deck construction process smoother and more efficient.

Remember, for decks that require plan review, the process typically takes 2-3 days once complete code compliant information is received. However, certain decks like freestanding, attached, and smaller rectangular ones can generally be issued permits the same day at the permit counter.

Don’t forget that all permits require a site plan, and this can be made using Peoria County’s GIS map to get an aerial view of your property.

Lastly, if your project involves a swimming pool, be prepared to submit a building permit application for both the pool and the deck, as these need to be issued concurrently to meet the barrier requirement.

Adhering to these guidelines will not only save you from potential legal and financial complications but will also ensure that your deck is a safe and enjoyable addition to your home. Happy building!
