The orderly growth of Massapequa Park has been guided by a Planning Commission appointed by the Mayor with the consent of the Board of Trustees. The Commission also explores such subjects as improvements in traffic flow, parking requirements and land use. The Village Building Department issues permits to build, then inspects for conformance with the building codes, and finally issues a certificate of occupancy. All plumbing and construction work must have a permit from the Department and must conform to New York State building and fire safety codes. The Village maintains a list of licensed plumbers.
State codes cover building, plumbing and electrical work and fire and safety requirements.
Applications and requirements are available at Village Hall. The Ethics Board is appointed by the mayor. The Board acts as an independent body in reviewing matters pertaining to the State Code of Ethics.
