On Tuesday, Boulder County commissioners voted 2-1 to approve stricter limits on the size of new homes and additions in unincorporated parts of the county, despite a unanimous recommendation from the county planning commission to deny the changes. New homes in Boulder County have grown 11%, from an average of about 3,500 square feet that year to roughly 3,900 in 2023. When basements, porches and garages were included, Boulder County new homes averaged more than 4,700 square feet in 2023. In March, following a four-hour public hearing, the Boulder County Planning Commission unanimously recommended against new size caps and lift the moratorium. “I’m concerned … about disparity across neighborhoods in Boulder County … and the fact that people in neighborhoods with large homes get to build large homes," she said.
