Mahmood's legislation, set for formal introduction June 9, regulates transparency: landlords would have to list an all-in monthly cost and couldn't evict a tenant over a fee they failed to disclose. What it does not touch is legality. Under San Francisco's Rent Ordinance — Administrative Code Chapter 37 — "rent" is defined to include consideration for "housing services of any kind," and the ordinance sharply limits which costs a landlord can pass through to a tenant mid-tenancy. That gap means a fee can be perfectly disclosed under Mahmood's bill and still be an illegal rent increase under the law already on the books.

San Francisco's rents are up 21 percent year-over-year, with the median one-bedroom hitting $4,000 for the first time, Mission Local reported in breaking the story of Supervisor Bilal Mahmood's bill. On top of that, tenants are increasingly billed for pest control, garbage, water and other "services" never quoted in the advertised rent — charges that, by one analysis from the Urban Institute Initiative cited by Mahmood, can add 10 to 30 percent to a renter's monthly cost.

Mahmood's response is a disclosure mandate. Listings on sites like Zillow and Craigslist would have to show an estimated all-in monthly price; leases would have to itemize every recurring fee. A tenant who could prove a fee was never disclosed couldn't be evicted for not paying it, and could break the lease penalty-free.

"Junk fees are a major obstacle to housing stability. They blindside renters who have already very stretched, tight budgets," said Ora Prochovnick, director of litigation and policy at the Eviction Defense Collaborative, who worked with Mahmood on the bill.

But the framing — that the problem is hidden fees — sidesteps a question one of Mission Local's own readers put bluntly in the comments: "Charging additional fees outside of monthly rent constitutes a rent increase. How is this practice permissible under SF's current rent control ordinance?"

It's a fair question, and the answer cuts against the landlords. The Rent Board estimates that roughly two-thirds of the city's apartments are rent-controlled; the Housing Rights Committee of San Francisco summarizes the test as virtually all units in buildings of two or more units built before June 1979. For those tenants, the annual rent increase is capped (1.4 percent for the current year), and the ordinance treats almost any new recurring charge as part of "rent."

Chapter 37 defines "rent" expansively, to include consideration for "housing services of any kind." The Rent Board permits only specific, regulated pass-throughs — and even those generally require a petition and Board approval. Utility pass-throughs, for instance, are narrowly limited. A landlord who simply tacks a new $75 "pest control" or "trash" line onto a controlled tenant's bill has, in effect, raised the rent above the legal cap — without the petition the ordinance requires.

The remedy already exists, and the disclosure bill never mentions it: a tenant can file a petition with the Rent Board alleging an unlawful rent increase or decrease in services, and can seek a refund of overpayments. That is a stronger right than the one Mahmood's bill creates. His measure lets a wronged tenant leave or avoid eviction; existing law may let them stay and claw the money back.

There's a genuine limit on how far this can be pushed. The Dissent did not locate a published Rent Board decision squarely holding that a specific "junk fee" — pest control, say — is per se an unlawful rent increase, and tenant advocates note these disputes are fact-specific. Costs that were itemized and agreed to at the start of a tenancy stand on different footing than charges imposed mid-lease.

That nuance is precisely why the legality question matters — and precisely what Mahmood's transparency-only bill leaves on the table. Disclosure tells a rent-controlled tenant exactly what they're being charged. It doesn't tell them they may not legally owe it.
