ADC’s compensation structure is determined by the finished square footage of a home. Finished square footage is defined as all heated spaces plus screened, 3-seasons, and 4-seasons areas. ADC’s design rate is $1.30/sqft for finished area on the first and second floors, and a design rate of $.65/sqft for finished basement area. Once the plans go out for bids we invoice for the balance of the plan. You’re not quite done with us yet! We include 3 free hours of additional changes for after the bid. We can get a lot done in 3 hours of clean up changes if your bid comes in a little low or a little high. If changes exceed those 3 hours, any other time will be charged at a rate of $175 per hour.
