What is different about dock construction in Connecticut
Older housing stock means knob-and-tube, asbestos and undersized services surface constantly; budget for discovery work that newer-stock states rarely hit.
Owner-builder: Homeowners may permit work on a single-family home they occupy. Dock Construction generally requires a licensed contractor to pull the permit, even where owner-builder status is available.

Always. A residential dock requires a local building permit plus state environmental authorization, and most waterways also require federal Army Corps review. Exemptions exist for very small private docks but must be confirmed in writing.
