Harris County is different

Spring Creek is the line between Harris and Montgomery counties, and the Tomball and Spring ZIP codes cross it. Homes on the Harris side need four inspections a year. Homes on the Montgomery side, and in Waller and Grimes counties, need three.

Example calendars. Your visit months depend on when your contract starts.
