January, 2015: National Average Cost of Home Additions

“Remodeling Magazine” gathers data each year and shares its findings in an annual cost versus value report for midscale and upscale renovations and additions. The annual survey tracks the average cost and value of typical home improvements over time, and compares costs regionally and nationally. The annual survey assumes proper electrical, HVAC or plumbing tie-ins and code compliance, but does not take into account local labor availability or shortages, which impact labor costs. The survey does account for annual rises in supply and equipment costs, nor permit costs. Also, please note that San Diego building costs are obviously substantially more than the national “average” mostly due to our “weather” and “lifestyles.”
