What if my project is a Substantial Improvement?

If the proposed repair, remodel, rehabilitation, addition, or improvement, equals or exceeds 50% of the depreciated market value of the existing structure it is considered a substantial improvement and you will be required to conform to Chapter 18 of the Mill Valley Municipal Code. Depending on the zoning and floodplain designation you may be required to flood-proof the structure (commercial zones) or elevate the finished floor of the structure above the base flood elevation. If the proposed project is a substantial improvement, please refer to Chapter 18 of the Mill Valley Municipal Code, and discuss your scope of work with the Planning Department.
