Rent & eviction protection

Is 822-826 Filbert St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Built 1910
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The three-unit, three-story building at 822-826 Filbert Street in San Francisco's Russian Hill neighborhood, currently owned by the Koros Family Trust, has been in operation since 1910. Over the past seven years, the property has generated a notable number of service requests, totaling 48 through the city's 311 system, with a single recorded fire incident during this period. A significant pattern has emerged in recent months regarding driveway access issues, with six of the most recent service requests (between February 2025 and July 2026) specifically related to vehicles blocking the driveway, resulting in citations and tow requests, though in one case the responding officer was unable to locate the offending vehicle. The property has also engaged with the rent board process, as evidenced by a fee housing inventory customer callback in February 2026, which required assistance with address documentation. The concentration of driveway-related complaints, all resolved through official channels, suggests ongoing challenges with parking management in the vicinity, though these incidents have been systematically addressed through the appropriate authorities.

Risk rating

How 822-826 Filbert St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
