Boathouses are a great way to enhance your property, especially here in New Hampshire, where lake life is a time-tested part of the culture. But building a boathouse isn’t as simple as sketching a plan and breaking ground. As with most lakefront construction activities, boathouse design is well regulated to protect the lakes and it’s important to understand what’s involved before getting started.

New Hampshire’s Shoreland Water Quality Protection Act regulates most structural design within 250 feet of public water, including lakes like Winnipesaukee, Sunapee, and Newfound. Any construction, including a boathouse, will require a permit from the New Hampshire Department of Environmental Services (NHDES). You’ll also need to research local town zoning and conservation regulations, which will vary somewhat by municipality.

If your property qualifies for a boathouse, be aware that the state has strict size and shoreline location guidelines. For example, a new boathouse must be fully roofed, walled and placed over the water at no wider than 50 feet. There are also restrictions related to height, roof pitch, and location on the shoreline. These days, most new boathouses are limited to one story.

Although private, a boathouse has a significant visual impact on the lakefront landscape. Thoughtful design should celebrate natural surroundings and respect neighboring properties. Many homeowners work with architects and builders familiar with lakefront construction requirements. This helps the boathouse blend into its setting and comply with state and local regulations. From surveying to shoreline stabilization, permitting, engineering, and design, boathouse projects require collaboration. Working with professionals familiar with New Hampshire lakes can save time, money, and prevent delays.
