The May 28 issue of ENR California will include our annual rankings of the region’s Top Design Firms as well as a profile of Design Firm of the Year.

If your company hasn’t submitted yet, you can still be included by filling out the survey by May 3. Submit your firm's information for the California and Hawaii region by the deadline here. A pdf of the California design survey can be obtained here.

The annual rankings are based on data voluntarily provided by participating firms, which include consultants, architects, engineers and other design professionals. Rankings are based on total regional revenues of design services of participating firms. Design firms will also be ranked by state revenues and various design specialties and disciplines, as applicable. 

In the meantime, here’s an alphabetical list of the firms that have already submitted their surveys and will appear on the ranking. We will update this list as more firms submit surveys.
