San Tan Valley, AZ – Water restrictions are reshaping where homes can be built across central Arizona. Spencer Kamps, Vice President of Legislative Affairs at the Home Builders Association of Central Arizona (HBACA), delivered that message to the newly incorporated San Tan Valley council on December 17, 2025. He explained how state groundwater restrictions have halted residential development outside designated water providers—and why that could increase development pressure in communities like San Tan Valley that have secured water supplies.
HBACA lobbies state, county, and local governments on behalf of residential builders. The trade association represents over 100 builder members and nearly 600 total members across Maricopa, Pinal, and Yavapai counties.
