Summary
County Code Section 19.80.020(7) tells landlords exactly when a rental unit crosses the line into a public nuisance: inadequate maintenance, decay, faulty wiring or plumbing, or bad ventilation that leaves it unsanitary or unfit for human habitation. Once the code official makes that finding, the Dangerous Building Code's notice and abatement process takes over.
108.1.5 Dangerous structure or premises. For the purpose of this code, any structure or premises that has any or all of the conditions or defects described below shall be considered dangerous: ... i.A building or structure, used or intended to be used for dwelling purposes, because of inadequate maintenance, dilapidation, decay, damage, faulty construction or arrangement, inadequate light, ventilation, mechanical or plumbing system, or otherwise, is determined by the code official to be unsanitary, unfit for human habitation or in such a condition that is likely to cause sickness or disease.j.Any building or structure, because of lack of sufficient or proper fire-resistive construction, fire protection systems, electrical system, fuel connections, mechanical system, plumbing system or other cause is determined by the code official to be a threat to life or health.
Full Breakdown
5 defines a "dangerous structure or premises" through eleven listed conditions, two of which govern habitability directly. " Subsection (j) separately reaches units with insufficient fire-resistive construction, fire protection, electrical wiring, fuel connections or plumbing that the code official determines threatens life or health. 5. 020(6) requires that notice, any amended notice, and any permit issued after an abatement order be served on tenants of residential buildings too, either by first-class mail to each unit or by posting in a prominent place. Where the county orders vacation and repair or vacation and demolition, the owner has ten days in writing to elect which option to pursue and must submit a completion schedule for the building official's approval before work can proceed.
Violations & Fines
Landlords who ignore a habitability notice face vacate-and-repair or vacate-and-demolish orders, and if they miss the ten-day election deadline or the approved repair schedule, the county can obtain a Board of Supervisors order to do the work itself and bill the property. Unpaid costs become a recorded abatement lien collected with ordinary property taxes, at parity with tax liens under Government Code Section 25845. Interfering with the code official's enforcement is a separate violation under Section 19.80.050.
