Katz Development owns a wide-ranging portfolio of buildings including medical office, office, retail, and industrial buildings. Like our residential philosophy, company principals take a hands-on approach and operate each property through a vertically integrated formula. Most construction, tenant improvements, leasing, and management are handled in-house or through longstanding relationships with our business partners, which allow us to meet the needs of our tenants in a timely and cost-effective manner. Tenant retention and full occupancy are the keys to our success. To accomplish this we are constantly upgrading and improving our properties to make sure they continue to be some of the finest in the marketplace. Today our portfolio of commercial properties is occupied by some of the finest national, regional, and local tenants.
