Summary
Littleton's 2024 Fire Code amendment, Section 903.2.8, requires an automatic sprinkler system in every new Group R building, addition, alteration or change-in-use, and mandates sprinklers in all new townhouse units, but exempts standalone Group R-3 one- and two-family homes. The parallel IRC amendment leaves sprinklers optional, not mandatory, for those exempt single-family and duplex builds.
903.2.8 Group R. An automatic sprinkler system installed in accordance with Section 903.3 shall be provided throughout all new buildings, building alterations, building additions, and buildings undergoing a change-in-use with a Group R fire area, other than Group R-3 one- and two- family dwellings. New townhouse units shall be provided with an automatic sprinkler system.

The Fire Code is adopted under Charter Section 44 and administered by the Fire Chief and Fire Department serving the city.
