Our Story

Zone 4 Construction, Inc. started out as an electrical contractor in 1983. The company’s primary focus was electrical and data work throughout the greater San Francisco Bay Area. In 2001, Zone 4 Power and Construction was formed, transitioning from primarily doing electrical work, to becoming a full-service general contractor. To fulfill the needs of our clients, a “Turn – Key Construction Company” was born. Today, we are known to our customers as Zone 4 Construction, Inc., a general contractor that provides quality construction and management services for office renovations, exterior renovations, retail, medical and dental office renovations and structural upgrades..

True to our roots, we still perform electrical services, miscellaneous carpentry, and demolition services. This “one-stop-shop” strategy allows us to keep more resources on a project to help deliver projects on time.

Our executive leadership has 40 years of construction experience. Building strong relationships is important to us and we want to ensure that our clients have direct access to the ultimate decision makers in our company. One of our principals are involved in every project, from start to finish. We commit the highest level of time and resources to every job, while never compromising on quality, schedule and safety..
