Q. What is the purpose of the UDC?
A. The UDC is a uniform statewide code that sets minimum standards for fire safety; structural strength; energy
conservation; erosion control; heating, plumbing, and electrical systems; and general health and safety in new dwellings.
Q. What buildings are covered by the UDC?
A. Basically it covers new one- and two-family dwellings built since June 1, 1980 and their additions and alterations.
This includes:
- Seasonal and recreational dwellings (Electrical, heating or plumbing systems are not required, but if installed
they shall comply with the applicable codes. If a home is heated, then it shall be insulated. Local sanitary requirements
may require certain plumbing systems.)
- One and two-family condominium buildings
- A single-family residence connected to a commercial occupancy
- Community-based residential facilities with up to 8 residents
- Manufactured, modular or panelized dwellings regulated by the State (but not mobile or manufactured homes regulated
by the Federal Government)
- Additions to mobile or manufactured homes produced after June 1, 1980
- A non-residential building, such as a barn, that is converted to a dwelling.
Q. What structures are not covered by the UDC?
A. The following are not covered:
- Dwellings built before June 1, 1980 or additions and alterations to such dwellings
- Mobile (manufactured) homes which are instead subject to Federal standards
- Multi-unit (three or more) residential buildings which are regulated by the State Commercial Building Codes
- Detached garages or accessory buildings
Q. What about homes built before June 1, 1980?
A. The State does not have a construction or heating code for older homes or any accessory structures
or outbuildings. However, the State Plumbing and Electrical Codes and smoke detector codes do apply
to all dwellings, regardless of age.
NOTE: For construction and heating
standards for older homes, municipalities may adopt any or no code. Many use the UDC. Municipalities may also choose to adopt
the UDC for detached garages, accessory buildings and decks.
