The Village of Riverside requires that all building and construction projects (including alterations and repairs) that cost more than $500 obtain a building permit prior to work beginning.  However, no demolition of a building (in whole or in part), structural, electrical or plumbing work of any kind may be performed without a permit regardless of the cost. (Plumbing or electrical work shall not include routine or regular maintenance and/or minor repairs.)  Certain projects such as accessory buildings (i.e. shed or garage), fences, decks, and driveways require a building permit regardless of cost.
 
Building permits (PDF) are required by the Village as a means of protection. Permits establish objective criteria and standard practices to protect both property owners and residents, neighbors and, in general, all citizens of the Village. The permit process insures these parties that: 

• Contractors are properly licensed and bonded.
• Work complies with building and life safety codes.
• A level of quality work is maintained throughout the Village.
• Appropriate building setbacks are maintained and property lines are not compromised.
