California Regulates the Inspection of Pools
Starting January 1st, 2018 California is requiring all homes sold that have a pool must be evaluated for certain safety features to prevent drowning. This includes spas and portable spas. If your home inspector is not insured, certified or accustomed to dealing with pools there could be more liability transferred to realtors and sellers if someone gets hurt or drowns.
