Cypress-Fairbanks ISD is the third-largest school district in Texas and the one buyers ask me about most. It serves Cypress, Copperfield, Bridgeland, Towne Lake, and most of northwest Harris County. Each campus page below lists the neighborhoods zoned to it and links to homes currently for sale in that zone. Cy-Fair’s attendance boundaries shift as the district grows, so verify any specific address with CFISD before writing an offer — I’m glad to help you cross-check.
