In 1992, City of Burbank Ordinance No. 3296 amended certain provisions of the Burbank Municipal Code (BMC) to prohibit the use of wood shakes and wood shingles for roof coverings and exterior wall coverings. All wood roofs in the Mountain Fire Zone were to be removed by August 14, 2005. In the remainder of the City, all wood roofs, even if covered by other types of roofing, shall be removed by August 14, 2012.
The City Council adopted an ordinance extending the deadline for removal and replacement of wood shake or wood shingle roof coverings. The ordinance officially goes into effect on July 13, 2012. The removal deadline was extended two years for exposed wood shakes or wood shingles and eight years for wood shakes or wood shingles that have been re-covered with other types of roofing such as composition or asphalt shingles.
THE NEW DEADLINES ARE:
For exposed wood shakes or wood shingles AUGUST 14, 2014
For re-covered wood shakes or wood shingles AUGUST 14, 2020
