California Standard Net Lease is a type of lease used in the state of California where the tenant pays a base rent plus additional costs such as taxes, insurance, and maintenance. The tenant is responsible for all costs associated with the leased property, including any needed repairs and improvements. The landlord is typically only responsible for providing the property and any repairs required due to his or her negligence. There are three main types of California Standard Net Leases: Single Net Lease, Double Net Lease, and Triple Net Lease. Single Net Lease requires the tenant to pay the base rent plus the property taxes. Double Net Lease requires the tenant to pay the base rent plus the property taxes and insurance. Triple Net Lease requires the tenant to pay the base rent plus the property taxes, insurance, and maintenance costs.
