Published local code-enforcement instructions; procedures and property jurisdiction remain agency-specific

Code Enforcement is a Division of the Lassen County Planning and Building Services Department. The primary function of the Division is to receive and respond to citizen complaints and referrals from other agencies and/or departments regarding alleged violations of applicable ordinances, codes, and regulations relating to fire, life, health, safety, blight, building, electrical, mechanical, plumbing, public nuisance, welfare, zoning, land use, and other matters of public concern. The County Code Enforcement program is complaint-driven. This means that, typically, the Department does not initiate code enforcement cases. However, cases are potentially opened (without a complaint) when a "dangerous" violation is identified necessitating action without a complaint.
