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 a boathouse is a private structure, it has a significant visual impact on the lakefront landscape. Thoughtful design that celebrates the natural surroundings and respects neighboring properties is a win for everyone. Many homeowners will work with architects and builders familiar with the lakefront construction process to ensure the boathouse blends into its setting and is compliant with all state and local requirements. From surveying and shoreline stabilization to permitting, engineering and design, building a boathouse is truly a collaborative process. Working with professionals who know New Hampshire’s lakes and the regulations that surround them can save time, money, and avoid delays and aggravation.
