Tips

  • Additions/remodels use the same application form and Building Division as new construction — there is no separate remodel-specific form.
  • The valuation-based fee table for remodels/alterations is a different schedule than the per-square-foot new-construction fee — use total project valuation, not square footage, for additions/remodels.
