When used according to DekBrands' recommendations, the Floating Foundation Deck System conforms to all national and regional building codes when the deck is unattached from the house. Even though it may comply with the states adopted building code, your city/county may not except this system. Due to the varying states building department structures, each township/county can be completely different. Even though a state may have one building code, the city may choose to impose greater regulations and restrictions. Verify with your local building department before starting any construction.

Building codes are based on interpretations. One inspectors interpretation of the code may be different than another inspector.

In the past few years, many states have adopted the International Residential Code. The International Residential Building Code has two specific sections that apply to residential deck construction:

"Section 105.2 - Work exempt from permit"

1. "One-story detached accessory structures, provided the floor area does not exceed 200 square feet (18.58sqm)"

"Section 103.1.4.1 - Frost protection"
Exceptions to frost protection

1. "Freestanding accessory structures with an area of 400 square feet (37 sqm) or less and an eave height of 10 feet (3048 mm) or less, shall not be required to be protected."
2. "Decks not supported by a dwelling need not be provided with footings that extend below the frost line."

The Floating Foundation Deck System has been accepted in 49 of the 50 US states. New Jersey is the only state that does not allow the system to be used.
