NH dock sizes allowed based on the water frontage of your property

Less than 75 feet A single 4-foot × 24-foot dock. You must have abutter’s consent if the dock will be placed closer than 20 feet to abutter’s property line.

75 feet to 149 feet 2 Slips
150 feet to 224 feet 3 Slips
225 feet to 299 feet 4 Slips
300 feet to 374 feet 5 slips

New docks or additions to existing docks must be located at least 20 feet from abutting property lines, including the imaginary extensions of those property lines over the water. Any boat secured to a dock may not extend beyond the extension of the abutter's property line.

If an applicant proposes to place docking structures within 20 feet of an abutter’s property line or the imaginary extension of the property line over the water, the applicant must provide a signed, notarized letter from the adjacent property owner granting permission for the new docking structure to be placed within 20 feet of his/her property line.

Of course docking structures that do not meet today's regulations but were in place before the current regulations are generally grandfathered as long as they were legal when they were built.

New docks can be 40 feet long. 🐻

Thanks. This is good info.
They have alot of frontage, but are WAY over what they should have.
I have what I think is a grandfathered dock, permanent with piers thats about 80 feet. (needs to be, water very shallow).
My neighbor on the other side of me has about 100' with fingers that he completely rebuilt two years ago, all his permits for that show up, we did get a notice for that one because of the angle of the property line and the length of his dock pushed the end into the imaginary line. They had no problems with the state getting approvals for any of it. All is good on that side of us though, never any problems.
The others are definitely in violation of the 20ft rule. They are less than a foot to the property line with the closest one, and the have multiple shore jacks/cradles within 20 feet. They also have a seasonal dock further down.

Does the 40 foot rule hold regardless of frontage???

[Barney Bear]

I believe so. DES can confirm this belief. 😇

Keep in mind the 40' of length is only for seasonal, not permanent docks. This is not valid for lots with less than 75' of frontage.

Also frontage for permitting purposes is calculated as an average between actual running feet and the measurement of pin to pin.

If you have less than 75 ft of frontage, can you get a dock longer than 24' if the water level is too shallow and below the 36" depth required. I know you could previously to the changes made in Dec/Jan. How about now.
My 24' dock is too shallow to store a 20' boat come Sept/Oct when the lake is drawn down.

My friend who bought property in Alton Bay had his waterfront surveyed. He had about 50 ft or so of shoreline. He owns a 26ft Cobalt, and at 24 ft, the water was only knee deep. With his survey, he got approval for a 60 ft seasonal dock (6 10 ft sections). He went before the Conservation Board in Alton, got their stamp of approval, then down to DES. They had one or two questions, and gave approval. Installing the dock, he has to maintain 25 ft from his extended property line on the east side if his property. Easy process.

Was this before or after January 2020, as the rules may have changed after he applied

It was 5 years ago. After speaking with him the other night, his point to point frontage (boundary pin to pin) was mid to upper 60s, and the measurement at the water line was still a few feet short of the 75 ft mark. He applied for and got the exception as stated above.
