Renting in Commerce: the rules that apply
Commerce has its own rent cap and just-cause eviction rules, including a limit on owner move-in evictions of older or disabled long-term tenants. Notices, deposits, repairs and entry follow state law.
Key points
- Rent increases: Commerce limits increases to 5% plus the cost-of-living change, or 10%, whichever is lower, per 12 months; exempt housing is not covered.
- Increase count: Commerce allows no more than 2 increases in a 12-month period while the same tenant stays.
- Just cause: After 12 months of continuous, lawful occupancy, Commerce's eviction causes include unpaid rent, a material lease breach and nuisance.
- Owner move-in: Commerce bars owner move-in evictions when any tenant is 60 or older, or disabled, and has lived there 5 years or more.
- Relocation pay: State law requires 1 month's rent, paid within 15 calendar days of the notice, for no-fault evictions from covered units.
- Ending a tenancy: State law requires 60 days' notice to end a tenancy, or 30 days if the tenant has lived there less than 1 year.
