N.H. Rev. Stat. § 178:24
A business holding a license authorizing the consumption of alcoholic beverages on its licensed premise may petition the commission for permission to extend service for beverages and liquor to any clearly defined area under the control of the licensee. In addition, a licensee may expand into a shared space, such as a sidewalk or street, with the approval of local officials. Petitions shall include written plans and diagrams that shall provide detailed information on the proposed extension of alcohol service. Petitions shall also conform to local zoning requirements and include the written approval of local officials. Businesses served by a waste disposal system, as defined by RSA 485-A:2, XI, shall obtain approval from the department of environmental services for any expansion under this section, unless the total number of seats remains the same or is reduced. Businesses that are on municipal sewer may expand seating as permitted by the municipality. The commission may approve plans submitted by licensees and may add such terms and conditions as it deems appropriate to preserve public health and safety. The commission may deny, in its discretion, any petition under this section which constitutes a risk to public health, safety, or welfare of any community.
