Tips

  • Dewey-Humboldt's Grading Code is one of the few code chapters in this file that is NOT an adopted ICC model code — it is a locally authored ordinance (§ 150.08), so its specific technical thresholds (e.g., what cubic-yardage or slope triggers a permit) must be checked directly against the ordinance text rather than assumed from a standard IBC Appendix J-style threshold.
  • Grading work is commonly bundled into the same submittal package as a Residential Building Permit for new construction — the Town's own checklist groups 'Grading Permit' alongside 'Residential Building Permit' and 'Manufactured Home Permit' as the three permit types requiring the full 2-set construction plans and 18x24 site plan.
