There is a timeframe in which a non conforming property in a shoreland zone can be replaced. Generally it has to be replaced within 12 to 18 months from the time it was taken down. Well and septic have to be a certain distance from the shore and from the sidelines of the property. It is always best to speak with the Code Enforcement Officer in the town involved before beginning any waterfront property renovation. Towns must adhere to the minimum shoreland zoning regulations but they can be more restrictive depending on each town's shoreland zoning ordiance.
