Tips

  • Erie calculates new-construction valuation using its own fixed per-square-foot rates (not your stated project cost) — budget the permit fee off $169.09/sq ft (above-grade), $66.20/sq ft (garage), and $31.50/sq ft (basement), not your actual construction contract price.
  • A Land Survey Plat is now required for new residential builds (effective September 3, 2025) — factor the survey timeline into your pre-application schedule.
  • Mountain View Fire Rescue approval is a separate prerequisite sign-off before the Town will issue the building permit — coordinate with the fire district early.
  • The Town's 4-6 week 'first review comments' timeline is explicitly not guaranteed; workload, vacations, and incomplete submittals can extend it.

Erie, Colorado has adopted: 2021 International Building Code (IBC) — currently in force per the Town's Building Codes & Design Criteria page; Title 9 (Building Regulations) of the Municipal Code governs local amendments.

This document's own codes list (2021 IRC/IBC, 2020 NEC) predates the April 2026 IECC/NEC/IFC update, so these two figures should be reconfirmed with the Building Division (building@erieco.gov) if a general (non-solar) project needs them, since no separate general design-criteria table was found published on the Town's site as of this review.. Local amendments apply — see the Erie overview page for the full list.

The Town of Erie Building Division issues its own building, electrical, mechanical, and plumbing permits for all work within Erie town limits — Erie is a home-rule town with its own department, regardless of whether a given parcel sits in Weld or Boulder County.
