Milliken building permits

Tips & gotchas

• Milliken's Building Department is operated under contract by SAFEbuilt, which continues to do business locally under the ProCode Inc. name (the Town's 2020 contract was originally awarded to ProCode, Inc.). Building Officials Jonathan Gesick and Jose Gonzalez are both current SAFEbuilt staff, per the Town's own Building Department page. ProCode/SAFEbuilt serves Milliken from the same regional office (39 S. Parish Avenue, Suite 220, Johnstown, CO 80534, (970) 305-3161) that also serves the neighboring Town of Johnstown — the Town's own PV Solar Submittal Checklist is branded with this Johnstown address and phone number.
• Milliken publishes a three-tier review-timeline structure rather than a single figure, which makes scheduling unusually predictable. 'Counter Permits' — water heater, furnace, AC, re-roofing, siding and stucco, demolition, gas fireplace, window replacement, water and sewer line repair, lawn sprinkler, electrical service change, fences and walls, signs — run 24-72 hours. 'Residential Permits' — new construction, additions, remodels, basements, decks, patio covers, detached garages, sheds over 200 sq ft, and notably solar systems — run 10-14 business days. 'Commercial Permits' — new buildings, additions, tenant finishes, multi-family — run 14-21 business days.
• Fence and wall permits are free for Town residents — an unusually generous policy, and worth confirming applies to your project before budgeting a fee.
• As of January 1, 2026, the Town requires Class 4 impact-resistant shingles for all reroofing.
• Building valuation uses a 1997 UBC-derived per-square-foot cost table (e.g., $160/sq ft for above-grade floors, distinct rates for garages, decks, covered porches, basements, etc.) rather than the ICC Building Valuation Data table many other Colorado jurisdictions reference — confirm the correct per-square-foot rate for your specific project scope from the Town's own Chapter 18 fee schedule.
• The Town adopted the 2024 I-Codes (IBC, IRC, IEBC, IFGC, IPMC, IMC, IPC, ISPSC, IECC, IFC) and the 2023 NEC via Ordinance No. 834, adopted December 22, 2025, per the Town's own Inspections & Building Codes page.
• The Town publishes no Milliken-specific Table R301.2(1) Climatic and Geographic Design Criteria (ground snow load, wind speed, seismic category, frost depth) on its own site, and Milliken's own Municipal Code as hosted on Municode is not retrievable as readable text outside an interactive browser. Weld County's own published design criteria (30 psf snow load / 115 mph wind / 49-inch frost depth) govern unincorporated Weld County, not necessarily Milliken's own incorporated, SAFEbuilt-administered jurisdiction, so they are not cited here as Milliken's figures — the values remain genuinely unresolved rather than borrowed from an adjacent authority.
• No dedicated Accessory Dwelling Unit (ADU) permit application, checklist, or fee line item is published on millikenco.gov, despite the Town's 2024 resolution stating it has 'already undertaken efforts to allow ADUs with reasonable requirements.' There is no standalone ADU permit product to apply for — ask the Town how an ADU is permitted before you design one.
• Homeowners may self-perform electrical or plumbing work via a notarized Homeowners Affidavit; commercial projects always require licensed contractors.
• All permits, including Development Applications (plats, rezoning, site plans, etc.), are submitted through the same CommunityCore online portal; contractors must complete Town registration/licensing via CommunityCore before any permit will be issued, per Municipal Code Section 6-4-10.
