A:  Depending on how your contract is written with the home improvement professional, either you or the contractor will be responsible for securing government approval to perform most remodeling jobs.  Building codes set minimum public-safety standards for such things as building design and construction.  Codes vary from one state, county, city, and town to the next, but specialized codes generally exist for plumbing, electricity, and fire.  Each usually involves separate inspections and inspectors.  In addition, permits are generally required when any structural work is planned or the basic living space of a home is altered.  They generally cover new construction, repairs, alterations, demolition, and additions to a structure.  Some jurisdictions require permits to be posted in a visible spot on the premises while the work is being done.  Besides structural changes, permits also may be needed to cover the installation of foundations for tanks and equipment, as well as the construction or demolition of ducts, sprinkler systems, or standpipe systems.
