Full Breakdown

In unincorporated Orange County, the Planning and Development Services Department enforces the Uniform Housing Code (1997 Edition) as adopted and amended by County ordinance. Section 202 declares any substandard building a public nuisance and lists conditions that trigger it, including overcrowded rooms, insufficient ventilation or illumination, and inadequate or unsanitary sewage or plumbing facilities. The Building Official or Health Officer investigates and can order repair, rehabilitation, demolition, or removal.

Violations & Fines

Violating the Uniform Housing Code is a misdemeanor: a fine up to $500, up to 6 months in jail, or both, with each day of noncompliance a separate offense under Sec. 7-1-206.
