1. What codes apply?

Applicable codes include the Wisconsin Enrolled Commercial Building Code Ch. 50-64 (commonly known as the commercial code); the Uniform Dwelling Code (UDC) for one and two family dwellings; the Uniform Multi-Family Code, Ch. 66, for apartment buildings; and the Barrier-Free Design Code, Ch. 69. Buildings originally built before 1914 that have not been changed are subject to the Existing Buildings Code, Ch. 160-164. Also applicable are the Wisconsin Plumbing Code and the National Electrical Code.

2. What is the purpose of these codes?

These codes set minimum health, welfare, and safety standards in terms of life safety, fire safety, accessibility, energy conservation, ventilation, heating, sanitary facilities, erosion control, and structural soundness.

These codes are part of the state Administrative Code and have the effect of law. Changes are usually recommended by agency-appointed citizen code committees, endorsed by the agency, and given legislative review before they take effect.

To make sure the Code is followed, the state requires anyone constructing or remodeling most buildings submit their building plans and heating, ventilating and air conditioning (HVAC) plans to the state for review and approval before any local permit issuance or construction begins. Subsequent on-site inspections are made to ensure the approved plans are followed.
