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 for many people in the construction industry. Companies that supply materials and services to general contractors can use construction market trends and contractor data to connect with the right customers at the right time. By keeping track of important events like the start of big construction projects and reviewing permits, they can offer their products when contractors are most likely to need them. They can also study contractors’ growth patterns to focus on those who are expanding and may require more support. Subcontractors can use similar information to reach out to general contractors for new work opportunities. At the same time, real estate developers, property owners, and others looking to hire contractors can use detailed data to check the skills and reliability of contractors and subcontractors before working with them.
