Can I bill my tenants back for utilities (RUBS) in Los Angeles?
RUBS — Ratio Utility Billing System — divides a master-metered building's utility bill among tenants by formula (square footage, occupancy) instead of actual metered usage. In Los Angeles it works on non-RSO buildings and on new tenancies where the lease establishes it from day one, but it is effectively off the table for sitting RSO tenants: adding a new charge mid-tenancy functions as a rent increase, the 2026 RSO overhaul eliminated the old utility surcharges, and LAHD has formally recommended prohibiting RUBS in RSO units altogether. Verify the current ordinance status before implementing anything.
Where RUBS works — and where it doesn't.
The clean cases: a non-RSO building, or a vacant unit being re-leased, where the rental agreement discloses the RUBS methodology before the tenant signs. The dirty case is the one owners most want: converting a long-held RSO building where the owner has been eating the master water bill for decades. Imposing a new utility charge on a sitting RSO tenant is generally treated as an unauthorized rent increase, and the city has been moving against the practice — the RSO amendments effective February 2026 removed the old utility-based increase surcharges, and an LAHD report has recommended banning RUBS in RSO-covered properties outright, with existing RUBS charges folded into rent. As of mid-2026 that ban is a recommendation, not yet law — which is exactly why this deserves a current-status check, not a template from the internet.
The submetering alternative.
Submetering installs an actual meter on each unit so tenants pay their real usage — legally cleaner, fairer, and it changes behavior in a way RUBS never does (nobody shortens a shower over a formula). California law has required submeters on new multifamily construction since 2018, and retrofit submetering of older buildings is a legitimate capital project: cost varies with plumbing configuration, from modest per-unit numbers on simple layouts to prohibitive on buildings where lines interweave. When buyers underwrite expense-recovery income, they credit submetered recovery close to face value and haircut RUBS income — because one is durable and one is a regulatory target. If you are repositioning a building for sale, that difference shows up in the price.
Can I start RUBS when an RSO unit turns over?
A new tenancy is the moment terms reset — a lease that establishes utility billing from day one is on far stronger ground than adding charges mid-tenancy. But with LAHD recommending a full RUBS prohibition in RSO properties, confirm the current rules before writing it into leases.
Do utility charges count against the rent cap?
That is the direction the city is heading: LAHD's proposal treats RUBS charges as rent under the RSO. Under AB 1482, mandatory recurring charges are also generally analyzed as rent. Treat any tenant-paid utility scheme as something that must fit inside the applicable cap.
Is water submetering legal in California?
Yes — governed by state plumbing and weights-and-measures rules, and required on new multifamily construction since 2018. Retrofits are legal with proper installation and billing disclosures; get the plumbing bid before assuming the payback works.
