Caldwell, ID Fire Regulations: Brush Clearance (2026)

Caldwell does not impose California-style wildfire defensible-space brush-clearance requirements; the city sits in the largely flat, irrigated Treasure Valley rather than a high-hazard wildland-urban interface. Instead, overgrown vegetation is handled through Caldwell's nuisance-abatement program in City Code Article 11 (Nuisance Abatement; Appearance of Property). When a code enforcement officer determines a nuisance such as rank weeds or overgrown vegetation exists, the city issues a written request for voluntary compliance describing the condition and giving the owner roughly ten days to correct it. If the owner does not comply, the city may abate the nuisance itself and recover the cost. Under the abatement procedures, the city may levy a special assessment against the property pursuant to Idaho Code sections 50-1008 and 50-334, placing a lien for the cleanup cost. For burning of cleared brush, weed-abatement fires along noncombustible fence, canal and ditch banks are allowed only with a Caldwell Fire Department permit under City Code 08-17-07, subject to the air-quality, wind and distance conditions in 08-17-09. Property owners in outlying wildland areas should also follow Idaho Firewise defensible-space guidance even though it is not codified by the city.
