A Notice of Construction is a formal document that is issued by a local government or other authority when construction or demolition activities are taking place in an area. It is issued in order to inform the public of the upcoming work, and may include details such as the location, dates, estimated duration, and contact information for the project. There are two primary types of Notice of Construction: a Building Permit Notice and a Demolition Permit Notice. A Building Permit Notice is used when construction is taking place in an area, and can provide details such as the type of construction, the estimated cost, the zoning requirements, and any other relevant information. A Demolition Permit Notice is used when demolition is taking place in an area, and can provide information such as the type of demolition, the estimated cost, and any other relevant information. Both types of Notice of Construction must be approved by the local government or other authority before any work can begin.
