Class Code 9033
Housing Authorities
California WCIRB Class Code 9033 covers housing authorities that operate, manage, and maintain public or subsidized residential properties and provide tenant services. The approved pure premium rate for 9/1/2026 is $3.722 per $100 of payroll; knowing this classification helps housing authority employers control workers' comp exposure and stay Cal/OSHA-compliant.
What Class Code 9033 Covers
This classification applies to agencies and organizations that operate public housing developments, manage subsidized apartment complexes, and deliver resident services. Typical operations include property management offices, leasing and resident services, routine building maintenance and repairs, custodial and janitorial work, groundskeeping, security/patrols, and inspection of units. On-site capital repair work performed by the authority's employees (electrical, plumbing, carpentry) is included when done by payroll employees; separately contracted specialty trades are usually coded under their own trade classifications. Administrative staff working in the housing authority offices are included if payrolled by the authority and their duties are integral to housing operations.

- Nonprofit organizations operating subsidized or low-income housing

Common Injury Risks
Understanding the $3.722 Rate
The pure premium rate of $3.722 per $100 of payroll represents the insurer's estimated cost of expected lost time and medical losses for this classification. To calculate the pure premium, multiply total payroll for Class 9033 by the rate and divide by 100; insurers then add loss adjustment expenses, overhead and profit to produce the final premium. The actual premium an employer pays is affected by experience modification (loss history), payroll mix across classifications, deductible programs, state assessments, audits and the insurer's expense load.
Cal/OSHA Compliance Requirements
Employers in this classification must maintain an Injury and Illness Prevention Program (IIPP) and follow applicable Title 8 standards, including Hazard Communication (chemical SDS and labeling) and Bloodborne Pathogens when employees face needle or biohazard risk. Confined space, ladder safety, electrical safety and respiratory protection rules apply for maintenance and boiler/utility work, and employers must provide Heat Illness Prevention for grounds crews working outdoors. Serious injury reporting and OSHA/Cal/OSHA recordkeeping (300/301/300A) requirements also apply.

Which employees should I assign to Class Code 9033?
Employees paid by the housing authority who perform property management, tenant services, custodial work, maintenance, groundskeeping or on-site security are typically coded to 9033. Independent contractors and specialty trade subcontractors (for large renovation or HVAC projects) should be coded under their own trade classifications.
What practical steps reduce workers' comp costs for housing authorities?
Implement an IIPP, targeted training for lift/ladder safety and de-escalation, formal return-to-work/light-duty plans, routine hazard inspections (mold/asbestos checks), and prompt claims reporting and medical management. Consistent housekeeping and chemical SDS control also cut injuries and claims.
Are volunteers or resident aides covered under this class?
Unpaid volunteers are not typically covered by workers' comp unless state or local law provides coverage; paid resident aides who are on the authority payroll and perform operational duties would be coded to 9033. Confirm coverage specifics with your insurer or Key HR during onboarding.
