Summary
When Costa Mesa's development services department declares a rented dwelling a public nuisance and abates it for unsafe, hazardous, or illegal habitable-use conditions, Municipal Code Section 20-29 requires the property owner to pay the displaced tenant relocation assistance. A tenant current on rent who did not cause the condition receives two months' rent plus a refund of the security deposit, or another arrangement both sides agree to in writing.
In the event any structure which is rented or occupied for habitable dwelling purposes is determined to be a public nuisance and abated by the city due to unsafe or hazardous living conditions under the provisions of Titles 1 or 5 of the Costa Mesa Municipal Code, or due to illegal use or occupancy of the structure for habitable dwelling purposes, any tenant evicted as a result of such abatement, or notice of such abatement, who is not then in arrears or default of rent, and who has not caused or substantially contributed to the condition giving rise to the abatement, shall be entitled to receive from the property owner relocation assistance upon vacating the structure. For purposes of this section, relocation assistance shall consist of two months' rent and refund of any security deposit pursuant to Civil Code section 1950.5, or other arrangements agreeable to the tenant as evidenced by a written agreement between the tenant and the property owner. If the property owner is required to evict the tenants with less than 30 days' notice due to the condition of the structure, the owner shall provide the tenant with alternate, safe and legal housing for 30 days after notice of eviction.

Full Breakdown
Section 20-29 sits in Title 20's public nuisance abatement chapter and applies whenever a rented structure is abated under Titles 1 or 5 of the Costa Mesa Municipal Code for unsafe or hazardous living conditions, or because the structure is being illegally used or occupied for habitable dwelling purposes. The tenant must not be in arrears or default on rent and must not have caused or substantially contributed to the condition that triggered the abatement. 5. If the owner must evict tenants on less than 30 days' notice because of the structure's condition, Section 20-29(b) requires the owner to also provide alternate, safe, legal housing for 30 days after the eviction notice, on top of the relocation payment.
Section 20-30 conditions the tenant's entitlement on complying with the eviction notice, and Section 20-31 excuses the owner from paying relocation assistance when the unit became unsafe from earthquake, flood, or other natural disaster, unless the damage stays unrepaired more than three years or the disaster was caused by the tenant. The city maintains a dedicated reimbursable fund under Section 20-33 so relocation costs can be advanced to tenants even when an owner refuses to pay.
Violations & Fines
If an owner fails, neglects, or refuses to pay relocation assistance after a habitability-based abatement, Section 20-32 lets the city pay the tenant directly from the reimbursable fund, including the security deposit refund and alternate housing costs, then charge those costs back against the property or the owner personally. The city can record the debt as a special assessment against the property and pursue it as a personal obligation of the owner.
