Glenn County, CA Landscaping Rules: Tree Trimming (2026)

Glenn County Code Section 1.15.022(A) declares it a public nuisance for a property owner or occupant to maintain premises in a manner that includes any of the listed conditions, and item 5 specifically requires clearance of seven feet over sidewalks and fourteen feet over the streets for trees on the property. The rule sits inside Chapter 1.15, Public Nuisance Abatement, which the Board of Supervisors adopted by Ordinance 1281 in 2019 and which applies countywide to unincorporated Glenn County. An enforcement officer, defined in Section 1.15.040 as any county official or designee charged with enforcing the nuisance code, investigates reports of low-hanging limbs and can inspect the property with consent or, if refused, seek a court inspection warrant under Section 1.15.070.

Once a violation is confirmed, Section 1.15.090 requires the officer to mail or post a written Notice of Violation describing the tree-clearance problem, the parcel, and the corrective work required. The property owner or occupant has ten calendar days from service to request a hearing before the administrative hearing officer to dispute the nuisance finding. If the owner does neither, corrects, nor requests a hearing, the county may enter the property to trim the trees itself and recover the cost as a special assessment lien on the property, an unsecured tax roll charge, or a civil judgment under Section 1.15.060.

Where overgrown limbs create an immediate hazard, Section 1.15.080 lets the enforcement officer summarily abate the condition first and bill the cost afterward, subject to a later hearing confirming a nuisance actually existed.
