Building permit requirements are available by contacting the building department or permit office for a specific town or county. Different types of permits or even multiple permits may be required for some projects.
Some towns and counties have building permit applications and guidelines available online. It is possible to find some of these by visiting sites such as CityApplications.com. Always check with local government to make sure that all permit requirements are met before starting any construction.
Those building in cities may face restrictions that those in more rural areas do not. Permit fees often vary based upon the size of the construction project and if it is commercial or residential.
