Docks, Frontage & Water Access
A dock in a photograph is a question to investigate, not a guarantee of a transferable right, adequate depth or an expansion permit.
New Hampshire: freshwater is not tidal water
NHDES’s non-tidal dock guidance addresses new docks, changes in footprint, repairs and frontage measurement. New non-tidal docking structures require wetlands permitting; some limited repairs have different treatment. Do not apply freshwater guidance to a coastal property without checking the tidal requirements.
Maine: check both state and local review
Consult Maine DEP about NRPA applicability and the municipal code enforcement officer about local shoreland zoning before installing or altering a dock. Confirm any other required approvals rather than assuming a small or seasonal structure is exempt.
Your access checklist
- Private frontage, shared/deeded beach access, a mooring and a water view are different things. Review the deed, survey and association documents.
- Ask for dock permits, approved dimensions, maintenance history and evidence supporting any claim that a structure legally predates permitting.
- Check depth, tides or seasonal water levels for your own boat; investigate removal, storage and maintenance arrangements.
- For NH coastal moorings, the Division of Ports & Harbors uses an application process; do not assume a house purchase secures a permit.
Educational buyer checklist, not legal, engineering or insurance advice. NH and Maine have different rules; local ordinances and site conditions matter. Confirm deeds, surveys, permits and approvals with qualified professionals before relying on any advertised rights or planned changes.
