SB 721, California Health and Safety Code §17973
A new law, SB 721, was enacted in California requiring the inspection of any exterior elevated decks and their waterproofing systems for all apartment complexes and commercial housing.
This law states that a detailed inspection by a professional, such as a waterproofing expert, general contractor, architect or engineer, must occur. However, if the owner refuses an inspection, there are no financial penalties, but they will be responsible for upkeep and safety of their decks, as well as any associated costs.
