If you’re considering putting on an addition to your home, be sure to consult city hall before you get to work. Building permits are required in most cities, and plans must be reviewed before they the respective permits can be obtained. A survey or scale drawing or blueprint usually must be submitted by the owner or applicant. If you’re working with a contractor, be sure to discuss your project in order to gather the necessary information to ensure your addition will conform to your local building laws and codes.

When submitting your blueprint, be sure to include the following: lot size including map of adjacent streets, two sets of plans, and dimensions of all existing and proposed structures. Rules and regulations governing the construction and inclusion of setbacks, footings, smoke detectors, will vary from town to town. Separate plumbing, heating, mechanical and electrical permits for your addition may be required as well.
