My retaining wall is old and failing. Do I need a building permit to rebuild my retaining wall?

There are several factors to determine if a building permit is required for a retaining wall, including the height of the wall, whether the wall is part of a multiple wall (stepped) system, and how steep the slope is. More information on steep slopes and retaining walls may be found in the steep slopes and retaining wall PDF. You can also contact the building permits division to discuss your particular project to determine if a permit is required before starting any work.
