Why Get A Permit?

Building permits are safeguards to ensure that construction projects performed on private property are safe, meet environmental standards and comply with adopted building codes. These safeguards protect homeowners and their family, friends and neighbors from work that does not meet minimum code requirements. Building permits help protect an owner’s financial investment and minimize liability or problems during a future sale of the real estate.

For additional information on building permits see "A Guide to Home Improvements"
