As an expert in building floating decks, I am often asked: “Do I need a permit?” Answers vary depending on local regulations, the type of deck, and its size. Knowing the rules is important, whether or not a permit will be required. You’ll save time, money and hassles by doing this.
What is a float deck?
First, it is important to define what a dock on floats is. The floating deck can also be called freestanding deck or deck that is not attached. The deck is not permanently attached to any structure. It’s usually installed on concrete blocks, deck pilings, or the ground. This deck type is popular due to its affordability, ease of installation, and flexibility in placement. Some homeowners think it is not necessary to get a permit since it’s attached to no structure.
What is the permit requirement?
Many jurisdictions require a permit based on the height and size of the deck. You may not need a permit if the deck is less than 200 square feet and 30 inches or lower above the ground. You may need to get a permit if the deck exceeds these limitations.
If your floating deck includes additional structures such as railings, stairs or built-in seats, the permit requirements may be affected. Decks that are below the height or size thresholds can require permits if they have these features, especially if there is safety concern or if the structure interferes drainage, visibility or access.
Why you should always check with your local authority
Building codes and zoning laws vary widely from one city or county to the next. What’s allowed in one area may be banned in another. Before starting any construction, it’s important to contact your local building department.
They can provide you with accurate information about:
- Height Minimum and Maximum
- Setback Regulations (distance from property lines)
- Specifications for load bearing components
- Materials allowed and safety standards
- Construction inspections during and after construction
If you fail to get the necessary permit, it could lead to fines, delays or even an order to dismantle your deck. If you discover unpermitted work, it can impact your ability to sell the property in the future.
Bottom Line
Although floating decks are considered to be less “permanent”, they must still adhere to local regulations. In some cases, permits are required.
If you are in any doubt, consult your local building authority. A quick phone call or visit could help you avoid future problems. Plan ahead so that your floating deck is not only beautiful but also safe and legal.
If you do the right thing, you can enjoy your outdoor space with peace of mind.
