For years a common East Bay practice was to keep the base rent under the local or statewide cap and recover rising water, trash, or administrative costs through separate line items. Ratio utility billing systems, flat trash fees, portal charges, and notice-delivery fees all fit that pattern. State and local enforcement has now made clear that when those charges are mandatory and new to an existing tenancy, they are frequently treated as part of the gross rental rate. Adding them on top of an already-maxed rent increase is how owners discover they have exceeded the legal limit without ever changing the number printed on the lease.
The shift is not theoretical. In late 2025 the California Attorney General and the Marin County District Attorney settled with Mission Rock Residential over precisely this practice. The company had raised rents for roughly 140 households close to the Tenant Protection Act ceiling and, at the same time, began charging those tenants for water, sewer, and garbage through a RUBS formula that had previously been included in the rent. The combined cost pushed many households above the statutory cap. The settlement required $495,000 in penalties and restitution plus injunctive terms that restored the prior structure. Prosecutors described the utility charges as “shadow rent.” That phrasing is now the working description for any new mandatory fee layered onto a capped tenancy.
How the Statewide Cap Actually Counts
Under Civil Code section 1947.12, an owner covered by AB 1482 may not increase the gross rental rate by more than 5 percent plus the regional change in the cost of living, or 10 percent, whichever is lower, measured against the lowest gross rent charged for that unit in the prior twelve months. The allowable percentage resets each August and varies by metro area. Local ordinances in Oakland, San Leandro, Berkeley, Alameda, and elsewhere are often stricter; where they are, the local rule controls.
The statute looks at the total amount the tenant must pay as a condition of occupancy. When a landlord who previously included trash in the rent begins charging a separate $40 or $50 monthly trash fee, that amount is added to the base rent for purposes of the cap calculation. If the owner has already taken the full allowable percentage increase, the new fee pushes the total over the limit. The same arithmetic applies to a newly imposed RUBS charge, a mandatory “benefits package,” or a required portal fee. Optional services the tenant can decline are different; unavoidable conditions of the tenancy are not.
The practical test is simple. Write down the lowest rent charged in the prior twelve months. Add every mandatory charge the tenant must now pay that was not required twelve months earlier. Compare the sum to the current allowable percentage. If the total exceeds the cap, the excess is an illegal increase regardless of how the lease labels the line items. Owners who run this calculation only after a tenant files a petition usually learn the number is higher than they expected.
What the Mission Rock Settlement Changed in Practice
The Mission Rock case did not invent a new rule; it applied the existing definition of gross rental rate to a common unbundling tactic. The company managed a portfolio that had previously included utilities in the rent. After it assumed management it notified tenants that water, sewer, and garbage would thereafter be billed separately under a ratio formula, while base rents were raised close to the statutory maximum. Some households also faced a new insurance-related charge. The Attorney General’s complaint alleged that the combined amounts exceeded the Tenant Protection Act limits.
The settlement required the company to restore lawful rates, stop charging utilities in a manner that exceeded the cap, and pay a combination of civil penalties and restitution. It also imposed ongoing compliance terms. Because the case was brought by the Attorney General and a county district attorney, it established a public template. Local prosecutors now have express authority under SB 567 to enforce the Tenant Protection Act directly. An owner who introduces a new mandatory utility charge mid-tenancy in a capped unit is no longer dealing only with a private tenant dispute; the same facts can support a public enforcement action.
RUBS itself is not universally illegal. In buildings that have always billed utilities separately, or in new tenancies where the charges are disclosed and the total is set within the applicable cap from day one, the structure can still be used. The risk concentrates on existing tenancies where the owner attempts to shift a previously included cost onto the tenant without reducing the base rent by a corresponding amount or obtaining any required local approval. In rent-stabilized cities the local board may require a formal downward adjustment or treat the shift as a prohibited increase. Our earlier discussion of California utility billing rules and the Alameda ordinance on unmetered fees walks through how quickly a previously routine practice can become non-compliant.
Advertising Rules and Mandatory Fees
Separate from the rent-cap arithmetic is the question of how prices are advertised. California’s SB 478, the Honest Pricing Law, amended the Consumer Legal Remedies Act to prohibit advertising a price for a good or service that does not include all mandatory fees other than certain government taxes and reasonable shipping. The law took effect in July 2024. While pure residential leases have historically sat outside some CLRA provisions, the Attorney General’s guidance and subsequent landlord-industry interpretations have treated mandatory rental fees as subject to the same transparency principle: the first price a prospective tenant sees should be the price that includes every unavoidable charge.
In practice that means a listing that shows “$2,000” and then adds a required $50 valet-trash fee, a $25 portal fee, and a $15 administrative charge at lease signing is the pattern the statute targets. Government-imposed taxes and truly optional add-ons can still be excluded. Fees that depend on the tenant’s later conduct—late fees, damage charges, or returned-check fees where still permitted—are also outside the mandatory-price rule. The safe advertising practice is to display the all-in monthly amount a new tenant will actually pay and, if desired, provide an itemized breakdown only after that total is shown.
Federal enforcement has moved in the same direction. The Federal Trade Commission has obtained multi-million-dollar settlements from large national managers over undisclosed mandatory fees for pest control, trash, and similar services. Those cases do not bind California owners directly, but they illustrate the same enforcement theory: if the charge is required to occupy the unit, it belongs in the advertised price. East Bay owners who list on the major portals now face both state transparency expectations and the practical reality that incomplete pricing generates tenant complaints that can be forwarded to local prosecutors.
Notice Fees and Check-Processing Charges
SB 611, effective in stages during 2025, removed two long-standing cost-recovery practices. A landlord may no longer charge a tenant any fee for serving, posting, or otherwise delivering a notice required under the Civil Code or Code of Civil Procedure provisions that govern termination, abandonment, or unlawful detainer. That includes the three-day notice to pay rent or quit. The cost of preparing and serving those notices is now an unrecoverable operating expense.
The same bill prohibits charging a fee for payment of rent or a security deposit by check. Landlords must still allow at least one form of payment that is neither cash nor electronic funds transfer. A convenience fee for a voluntary credit-card payment remains permissible; a surcharge simply because the tenant chose to mail a personal check does not. Leases that still contain clauses authorizing either of these charges are out of date. Continuing to assess them after the effective dates creates a clear statutory violation that is easy for a tenant or a local prosecutor to document.
These prohibitions sit alongside the rent-cap rules rather than replacing them. An owner who stops charging notice fees but continues to layer new utility charges onto existing tenancies has solved only one of the problems. The combined effect of SB 611, the Honest Pricing expectations, and the Tenant Protection Act definition of gross rental rate is that most previously “unbundled” mandatory charges now either belong inside the advertised rent or cannot be added to an existing capped tenancy without a corresponding reduction elsewhere.
What a Defensive Billing Structure Looks Like
Begin with an inventory of every recurring charge currently assessed on occupied units. Separate those that were part of the original lease or have been in place for more than twelve months from those that were introduced later. For any charge added within the last year, recalculate the total housing cost against the lowest base rent in the prior twelve months and the current allowable percentage. If the sum exceeds the cap, the excess needs to be removed or the base rent reduced so the total returns to compliance. Doing the arithmetic before a tenant or a prosecutor does it is the difference between a quiet correction and a public settlement.
For new tenancies, set the advertised rent as the all-in figure that includes every mandatory fee. If utilities will be billed separately, disclose the method and the estimated range in the listing and in the lease, and confirm that the total remains inside any applicable local or state cap. In rent-stabilized cities, check whether the local ordinance requires utilities to be included, prohibits RUBS, or demands a specific petition before any cost shift. Alameda’s recent rules on unmetered fees are one local example; Oakland and San Leandro maintain their own variations. Full-service East Bay rental property maintenance and lease administration already track these distinctions so a single portfolio does not apply a San Leandro practice to an Oakland unit.
Update lease templates to remove any authorization for notice-delivery fees or check-processing surcharges. Confirm that at least one non-cash, non-EFT payment method remains available. Keep the calculation worksheets, the prior twelve months of rent ledgers, and the current utility bills in the same property file. When a question arises, the documentation shows that the total was measured against the statutory definition rather than against the line-item labels in the lease. Properties under coordinated complete property management tend to surface these overlaps—rent-cap math, advertising disclosures, and prohibited fees—before they become enforcement matters.
Local Variations Still Control
Statewide rules set the floor. Local ordinances frequently set a lower ceiling and add their own definitions of what counts as rent. In San Leandro the combination of the city’s rent-stabilization ordinance and any utility-shift rules means an owner cannot assume that compliance with AB 1482 alone is sufficient. The same is true in Oakland, where capital-improvement and utility petitions follow their own timelines and documentation requirements. Treating every East Bay city as if it followed only the state statute is how owners create defective increases that must later be rolled back. Our San Leandro property management work already maintains separate compliance calendars for each jurisdiction precisely because the allowable percentages and the permitted fee structures differ.
Mixed portfolios therefore need a simple matrix: one column for the applicable cap (state or local), one for whether utilities are currently included or billed separately, one for any fees added in the last twelve months, and one for the resulting total-versus-cap calculation. Updating that matrix once a quarter takes less time than responding to a single tenant petition or a prosecutor’s inquiry. It also produces the records that demonstrate the owner measured gross rental rate the way the statute requires.
The Longer Pattern
Utility unbundling, portal fees, and notice charges were rational responses to rising operating costs under rent caps. They are no longer low-risk responses. The Mission Rock settlement, the expanded enforcement authority under SB 567, the transparency expectations around advertised prices, and the specific prohibitions in SB 611 have converted those line items into potential overcharges. The cost of a quiet internal audit and a lease revision is modest. The cost of a public enforcement action that requires restitution, penalties, and ongoing injunctive terms is not.
