Okay, let’s calculate this. As an architect in the San Francisco Bay Area, Peter’s skills in Autocad, Sketchup, and Revit are in demand. His experience with sustainable design and construction drawings adds value. According to national averages, architects with similar skills and experience can charge between $100–$200 per hour. Considering the Bay Area’s high cost of living, I’ll estimate Peter’s rate to be on the lower end of this range, around $125 per hour.
