Interested in building a boat dock? It will cost you an average of $15,010, but the typical range is between $4,049 to $25,970. However, there are a lot of factors that can affect the cost.
If you're fortunate enough to own a home on a lake or beach, why wouldn't you want a boat dock? It's the perfect place to go fishing, enjoy a morning coffee, or—of course—launch a boat for a day out on the water.
This guide will break down the costs associated with this project and what your final bill is likely to be.
It will cost between $15 and $40 per square foot to build a boat dock. Since many docks are about the same width, you may pay based on linear feet or how far the dock extends. In that case, the average pier would cost $100 per linear foot.
Building a boat dock is not as simple as buying some nails and wood. There are also pilings (in the case of permanent docks), stone in many cases, and extras such as ladders and ramps to consider.
| Boat Dock Feature | Average Cost |
|---|---|
| Piling | $10–$15 per foot |
| Drums or floats | $75–$400 each |
| Ladder | $100–$600 |
| Bumpers | $50–$100 each |
| Ramp | $500–$1,000+ |
| Mooring whips | $300–$500 each |
| Decking | $4–$40 per square foot |
| Boat lift | $1,000–$1,500 |
| Boathouse | $10,000–$50,000+ |
Wooden pilings for dock decking cost $10 to $15 per foot. Pilings are driven deep into the sandy bed of the body of water where a dock is built. They remain in the water year-round to create a stationary dock that's ideal for fishing.
Dock float drums and other specialized float containers cost $75 to $400 each. These are used for floating docks, also called barrel docks, and allow the dock to float along the water's surface.
Dock ladders cost $100 to $600 each. Ladders allow swimmers and tubers to get in and out of the water safely, lowering the risk of injury when climbing back onto the dock. Ladders can be wood or aluminum and always come with special hardware to secure them to the dock for stability.
Dock bumpers cost $50 to $100 each. Bumpers are installed along the sides of a dock to protect both it and the boats during the docking process. When boats gently hit a bumper, the dock bounces back slightly without causing damage to either structure.
Installing a dock ramp costs $500 to $1,000 or more. Ramps allow dock owners to move their watercraft in and out of the water more easily. They're designed to launch boats safely and can be used to back a boat into the water from a vehicle.
Mooring whips cost $300 to $500 each, depending on the brand and size. They look similar to fishing poles and protect boats in areas with rough wakes. Each whip is affixed to an angle, tensioned, and arched downward to hook a boat. The tension then keeps the boat at a safe distance from the dock to protect its finish and prevent dock rash.
Decking makes up a dock's surface and costs $4 to $40 per square foot, depending on the material used. Simple wood decking falls at the low end of the cost range, while durable concrete decking tends to cost the most. Choose your decking based on how long you want it to last and your aesthetic preference.
Boat lifts cost $1,000 to $15,000 each. Lifts raise and lower boats into the water to help passengers board and exit more easily. They also keep boats secure to prevent them from floating away, especially when water levels are high. In the off-season when your boat isn't in use, a lift can keep it out of the water to prevent wear from freezing water temperatures.
A boathouse costs $10,000 to $50,000 or more. This roof-covered structure shelters watercraft and stores marine equipment in a protected environment. Costs vary depending on style choices and the addition of custom features such as plumbing, outdoor kitchens, fireplaces, and guest suites.
Generally, you should expect that half of your costs will go toward labor. So, if you received a quote for $10,000 from a dock construction company, about $5,000 of that will be labor costs, and the rest will go toward materials.
There are five main types of boat docks: floating docks, piling docks, pipe docks, crib docks, and suspended docks. Each dock type has its own price tag and benefits.
A floating dock isn't supported by pier pilings; it simply floats on the surface of the water. Therefore, installation costs will be much lower. This type of dock costs between $15 and $35 per square foot, which doesn't seem much lower than other docks, but keep in mind floating docks tend to be much smaller overall.
A dock that is built on pilings, or large wooden pillars driven into the ground, is sturdy and long-lasting. It’ll cost you between $20 to $40 per square foot to build.
These docks are similar to piling docks in that they are permanent, but a contractor builds them in a different way: They pour rock into a “crib” made of wood to create small islands to support the dock. These will cost you between $10,000 and $50,000.
Pipe docks are generally prefabricated and constructed with aluminum pipes. These docks are easy to assemble and move to a different location (although they aren't as durable) and will cost you between $1,000 and $10,000.
A suspension dock is essentially a dock that can be raised and lowered like a drawbridge. This makes them pretty expensive to produce, as you'll need to hire an engineer to install one. In terms of cost, it's on a case-to-case basis, and there isn't really a range.
A lot of factors impact the final price tag of a boat dock. Generally, they fall into four main categories: materials, size, type, and location.
There are many different types of wood to choose from for a boat dock. Some types of wood, like cedar, will cost you as little as $4 per square foot, while exotic hardwoods will run you up to $25 per square foot. Composite and aluminum can go even higher at $30 to $40 per square foot.
Docks can range widely in terms of size. If you just want a simple platform in some shallow water, it will be much less expensive than a large, sturdy dock extending dozens of feet from shore. The cost of docks is often expressed in square feet, so the bigger it is, the exponentially more expensive it gets.
You may pay just $15 per square foot for a floating dock, meaning a 10-by-10-foot dock would cost just $1,500. Meanwhile, a large crib dock could run you up to $50,000.
If you're building a permanent dock, the location matters. Are you building into relatively shallow water, and is the ground easy to dig? That's one thing. But if you're building into deep, rocky terrain, it gets a lot more challenging (and expensive).
You’ll pay more for your boat dock if you have to do any groundwork prior to starting this project. This includes leveling, foundation digging, and landscaping.
Check with your local city and state to find out what permits are required in order to build a boat dock. The price you’ll pay for these varies by location.
From optional enhancements to required seasonal maintenance, boat docks can come with a variety of additional costs.
Many dock owners build a roof over the dock or an entirely separate roofed structure for storage and entertaining. Expect to spend anywhere from $10,000 to $50,000 or more, depending on the complexity of the structure you build and the features you add. Some luxury boathouses include lifts, sundecks, plumbing, outdoor kitchens, fireplaces, or guest suites.
A seawall or lake bulkhead stabilizes the shoreline around your dock against waves, storm surges, and coastal erosion. Expect to spend anywhere from $150 to $600 per linear foot, depending on the size of the wall and the material used. Material options include vinyl, steel, concrete, and wood.
Dock maintenance requirements depend on the local climate, water type, decking material, and frequency of use. Inspect your dock at the end of each season and repair worn, cracked, or broken areas as you notice them. Depending on its material, you may need to stain, oil, or seal your decking regularly. Repairs or maintenance will come with material and supply costs.
If you have a budget for your dock and just want to know what you’ll get for it, this quick breakdown might help.
This is the super low end of what you're likely to pay for a boat dock. For this amount, you could build a small floating dock, or buy a prefabricated aluminum pipe dock.
This is closer to the more typical range of boat docks, although still on the low end. For this, you should be able to get a relatively small permanent piling dock.
This is the average price of building a dock. This most likely applies to a permanent dock, as it's higher than you'd likely pay even for the most expensive pipe dock. This would pay for about 500 square feet of a piling dock, so you would get a pretty substantial dock for this price.
This is the higher end of the typical price range. In this case, you could afford a very large piling dock with premium wood, or even a mid-range crib dock.
This is the most you'll probably pay for a dock, and that's if you get a large crib dock with high-end materials. However, suspension docks are a wild card because they require extensive engineering, which may exceed even this price tag.
Considering the fact that labor takes up about half the cost of any boat dock project, you can determine the cost to build one yourself by taking the price tags quoted above and halving it. That means all you'd be on the hook for is materials.
However, before you start watching YouTube videos on how to build a dock, consider the risks. For one thing, a poorly constructed dock can be dangerous. Also, if you don't do the job right, the dock may collapse under its own weight, or just give in to wear and tear years earlier than a professionally built dock. This could cost you big money.
Instead, contact a dock builder in your area for a consultation. They can take a look at the area where you want to put the dock and identify any potential complications. Then, they can provide you with a quote, which may be leexpectedxpecting. At the very least, it will give you peace of mind that you have considered all options.

It's possible to build your own boat dock or repair an existing boat dock, but only if you're an experienced DIYer and it's relatively simple, like a small floating dock. For larger and more complex projects that involve installing pilings or engineering a suspension structure, you're better off hiring a professional.
If you're building a permanent dock, it's very likely you will need to get a permit to do the project. Check with your local government to determine what kind of paperwork you must fill out before you can start.
Additionally, if you are a member of a homeowner association (HOA), they may have their own rules about docks, such as a minimum distance between your dock and a neighboring dock. You may need to check with all authorities to be sure you're in the clear: county, city, HOA, and any other organization with jurisdiction.
The length your dock can be will differ greatly depending on your location. Some localities will have rules; for example, some areas won't allow you to build a dock that is more than one-fourth of the width of a body of water. Other areas won't have any rules on length at all.
Here are a few other considerations before you build, even if you're convinced you're in compliance with the law:
Are you damaging the environment? Bodies of water are often delicate ecosystems, and building a dock can be destructive and disruptive to the wildlife.
Are you blocking access? Lots of people like to use a lake, so you need to make sure your dock doesn't block public access to the water.
Can you enclose the dock? Just because you can build a dock doesn't mean you can build any dock you want. Some areas don't allow enclosed docks, for example.
Do you need to follow any specific rules or guidelines? Check with the National Oceanic and Atmospheric Association (NOAA) Office for Coastal Management for any guidelines you’ll need to follow, including size and type restrictions.
