Tips

  • The City publishes an average building-fee estimate table by square footage, but explicitly states these are estimates only and may not reflect the final permit cost.
  • Mechanical, Electrical, and Plumbing (MEP) fees are each charged as a separate per-discipline fee, scaled to the same square-footage tiers as the building fee.
  • Impact fees (streets, parks/trails, police, fire) and capacity fees (water, sewer) are determined by Public Works separately from the Building Department's estimate and are not included in the published fee tables.
  • Applicants can view required inspections for their specific permit directly in the online Public Portal.
