Permit Information

A permit is a license which grants legal permission to start construction of a building project. Before any construction or remodeling work begins, application for a permit must be made.

Any individual or firm that will engage in the construction or alteration of any residential or commercial structure needs a permit. Permits are typically required for the following:

  • New Buildings
  • Additions
  • Alterations/Renovations
  • Demolition
  • Manufactured Homes
  • Accessory Buildings  
  • Prefabricated Structures (storage buildings)
  • Electrical Systems
  • Plumbing Systems
  • Mechanical Systems (HVAC Systems - heating, cooling, air conditioning)

Projects that do not require a permit:

  • One story detached accessory structures (sheds, etc.), if the floor does not exceed 200 square feet
  • A fence less than 6 feet high

What type of permit do I need?

There are five different types of permits:

  • Building Permit - This permit is for the actual physical construction of the project. Building Inspections are required for this permit.

  • Mechanical Permit - This permit is for the HVAC (heating, cooling, air conditioning) systems. Mechanical Inspections are required for this permit.

  • Low-Voltage Permit - This permit is for low-voltage electrical installations.

How do I apply for a permit?

You generally apply for your permits when you submit your plans for Plan Review.

Why are permits necessary?

Permits allow the enforcement of the State Construction Code Act, which has been adopted by law. This provides the means for Building Officials to protect us by reducing the potential hazards of unsafe construction, therefore protecting the public health, safety and welfare. Before any construction or remodeling work begins, application for a permit must be made. Permits provide the means for Building Inspectors to inspect construction to ensure that minimum standards are met and appropriate materials are used. The unit of government which enforces the code is acting to assure safe construction.

Building Officials and inspectors use permits as a vital step in their enforcement of codes. You have an investment in the home or business you are about to build or remodel. When that home or business building does not comply with the codes, your investment could be reduced. Applying for a permit notifies the Building Official that you are constructing or remodeling a building so he or she can ensure code compliance.

Are there other agencies I may need to contact?

Obtaining a permit is a relatively simple process. If you are building a new structure or an addition to an existing structure you may need permits or waivers from:
