Project questions
Frequently asked questions for Larimer County
Who handles permitting for this jurisdiction?
Larimer County Community Development Department, Building Division is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Building Division: (970) 498-7700; inspection request line: (970) 498-7697; building@larimer.org; planning on-call: (970) 498-7679 / planning@larimer.org.
How long might review take?
N/A; no standard plan-review issuance time was published. Residential and commercial applications expire if a permit is not issued within 180 days, subject to a possible one-time 90-day written extension; issued permits generally expire after 18 months unless extended.
How are inspections scheduled?
Request inspections by 11:59 PM the day before through the Larimer online portal or by calling (970) 498-7697; the permit and IVR numbers are required. Most areas receive building inspections daily and electrical inspections within two days, with limited schedules in some inspection areas. Keep the permit card, approved plans, visible address, and access available onsite. AM/PM requests are considered only for specified concrete, foundation, underground, slab, and interior mechanical inspections. Wildfire initial/final inspections use a separate County form.
Which codes and exemptions should I review?
For permits initiated on or after January 1, 2026, Larimer County lists the 2024 IRC, IBC, IECC, IEBC, IFGC, IMC, IPC, IPMC, and ISPSC, plus Colorado Electric Ready and Solar Ready requirements and the 2025 Colorado Wildfire Resiliency Code with Larimer County amendments. The County page lists the 2023 NEC for the current 2026 code package, while the Building Division separately states that the 2026 NEC becomes effective August 1, 2026; the State-adoption transition should be confirmed for permits filed around that date. The County FAQ states that detached structures under 200 square feet do not need a building permit but must meet setbacks. The adopted-code history also identifies discretionary exemptions from permit/specification requirements for agricultural buildings, private garages, carports, sheds, one-story Type V conventional wood-stud buildings up to 600 square feet, and small or unimportant work; private-use agricultural buildings of any size may also qualify at the Building Official's discretion. Minor work is still subject to applicable zoning, fire, electrical, plumbing, mechanical, and other requirements.
