In this article, we’ll talk about the most important deck building codes in Knoxville, TN, and what to do to avoid all the hassle of obtaining your permit,
Let’s begin.
What Are Deck Building Codes
Deck building codes are rules that need to be followed when building a deck. This is so the deck is safe for people to use without causing any problems.
There are different deck building codes for different areas, so you’ll need to make sure you get the right ones for Knoxville, TN.
You can find these codes online or from your local city office.
Once you have the deck building codes, you’ll need to follow them to the letter. If you don’t, you could be fined or even have to tear down your deck. On the other side, a code compliant deck means your space will be fully functional and safe for you and your loved ones.
The Most Important Deck building Codes in Knoxville, TN
There are three main codes you need to be aware of when building a deck in Knoxville, TN.
They are:
The International Residential Code (IRC)
The International Residential Code is the most important code for you to follow. This is because it contains the regulations that specifically pertain to decks.
You can get a copy of the IRC from your local city office or online.
The International Building Code (IBC)
The next most important code is the International Building Code. This code contains general regulations that all buildings must follow.
This includes things like fire safety and exit requirements.
The Tennessee State Building Code (TSBC)
The last code you need to be aware of is the Tennessee State Building Code. This code contains specific regulations that pertain to Tennessee.
It’s important to follow this code because it will ensure your deck is up to the state’s standards.
You can get a copy of the TSBC from your local city office or online.
Note: For free standing decks, the problem with building permits is different. Most free standing decks don’t require a building permit, as they are not attached to the house and they’re independent structures. As long as your deck is not elevated from the ground, chances are you won’t need a permit to build it.
The Application Process For A Building Permit
You will need to pull a permit in order to build your deck in Knoxville, TN. If you’re building a deck on your own or with an unlicensed deck builder, you should know there’s a lot of paperwork and a lot of back and forth to obtain the permit for your local city office.
In order to get the permit, you will need to submit a few things:
- A site plan that shows where the deck will be located on your property
- The dimensions of the deck
- A list of materials you will be using to build the deck and the deck surface
- A copy of the building codes
- A fee for the permit
Once you have all of these things, you can submit your application and wait for it to be processed.
It usually takes a few weeks to get a permit, so make sure you plan ahead.
