Our annual ranking of top construction firms highlights the top companies in Sonoma on their project volume over the past year, with a focus on relevance. This compilation is derived from permit and contractor information sourced from city, county, and state building departments through our partners at BuildZoom. For further information regarding data accuracy, please consult the note at the end of this article.

Construction data is useful to many people in the construction industry. Companies that supply materials and services to general contractors can use construction market data to find the right time to connect with contractors, especially when big projects are starting and new resources are needed. They can also identify contractors who are growing their business by analyzing construction activity, helping them focus their efforts on promising opportunities. Subcontractors can use similar information to reach out to general contractors for potential work. At the same time, real estate developers and property owners can use construction data to check the skills and experience of contractors and subcontractors before hiring them.
