Building Permit Information

Planning on remodeling that old house? Time to finally build that addition or finish the basement for the extra space you need? What many people don’t realize is that most home-improvement projects require a building and/or trade permit from the township.  Along with state construction codes, there are many local ordinances that can regulate elements of a home-improvement project.

Here are some answers to questions regarding permit requirements. Please contact the Community Development Department directly with any questions or for exact construction code regulations.

  • A homeowner may secure permits for work he/she is performing on the home where they reside.
  • State law requires that a licensed contractor secure permits for renovations to dwellings or structures where the homeowner does not reside.
  • Make sure your builder is licensed, insured, and has obtained the necessary permits. You can call the State to verify past complaints about a contractor at 900-555-8374.
