What does it cost to build a dock?

When considering a dock project, google some version of the question:
“How much does a piling dock cost?”

Average dock costs range from $25 to $60 per square foot, and removal
and disposal of old docks generally ranges from $15 to $25 per square foot.

What is involved in the cost of a dock?

There are many variables that go into estimating the cost of a dock. For example:


D.E.P. limits the size of permanent docks to a multiplier of 10 with a minimum of 1,000 square feet. To calculate this, take the the width of the property and multiply it by 10 to find your exempt square footage. For example, if your property is less than 100 feet wide, you are allowed the 1,000 square feet. Anything larger will require a lease of the land from SWFTMD. This process is time consuming and expensive, but possible.

Materials Used

Any lumber we use will be pressure treated to the maximum allowable by the state. We use no “box store” lumber. (“Box store” lumber has a limited 7-10 year lifespan in an aquatic environment, while we have some docks that are 30 years old and are still structural.) Composites vary in price depending on make and model, but you can plan on a minimum 25% increase in cost over lumber.

Soil Conditions

Probing the soil to determine density.


Underwater or underground obstacles (typically fallen trees).

Current Dock

Current dock material and condition.


Accessibility of the site for equipment and materials. (Barges will add 30%-40%).


Every project will need drawings that are sealed by an engineer. Permit costs can vary based on location, and may require more than one permit. Examples of permits you may need include: DEP, USACE, as well as local and county permits. Depending on your location, obtaining the necessary permits can take 1 week to 2 years or more. In Polk County, permits typically take around 30 days for issue.
