Only Colorado 'permissible fireworks' under C.R.S. 12-28-101(8) - sparklers, ground spinners, fountains, and snakes - are legal statewide. All aerials, firecrackers, bottle rockets, Roman candles, and audible explosives are illegal. Larimer County has extreme wildfire risk after the 2020 Cameron Peak Fire (Colorado's largest wildfire on record) and East Troublesome Fire. The Larimer County Sheriff routinely imposes Stage 1 and Stage 2 fire restrictions under C.R.S. 30-15-401(1)(n.7) that ban all fireworks countywide; restrictions are now zoned by elevation (below 6,000 ft, 6,000-9,000 ft, above 9,000 ft).

Larimer County Ordinance 11122002O001 (Code Chapter 6) requires dogs to be on a leash no more than 6 feet long when off the owner's property, or confined by a fence. Dogs over 4 months must be vaccinated against rabies and licensed annually. Larimer Humane Society enforces at 970-226-3647.

Unincorporated Larimer County allows residential fences up to 6 feet without a building permit. Fences over 7 feet with a solid wind-impermeable surface require a building permit, fences in road setbacks cap at 8 feet, and the maximum residential fence height is 9 feet under the Land Use Code.

Larimer County Ordinance 97-03 (codified at Code §30-155) limits residential noise to 55 dB(A) from 7:00 AM to 7:00 PM and 50 dB(A) from 7:00 PM to 7:00 AM in unincorporated areas. A 10 dB(A) bonus is allowed for up to 15 minutes per hour during the day under CRS §25-12-103.

Larimer County has been an NFIP-participating community since 1974 and administers floodplain regulations under Article 12 of the Land Use Code. A Floodplain Development Permit (FDP) is required before any development in regulated floodplains, including the FEMA Floodplain, Best Available Floodplain, Municipal Floodplain, Poudre GMA Floodplain, and County Flood-Prone Areas. Substantial improvement (50% of market value) triggers full compliance. New construction in the floodway is prohibited. Big Thompson and Cache la Poudre corridors carry the highest risk after the 1976 and 2013 floods.
