Rent & eviction protection

Is 551-555 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-story, four-unit residential building at 551-555 Filbert Street in Telegraph Hill, owned by Brian D. and Lisa R. Szady, has a documented history dating back to its 1910 construction. In recent years, particularly during 2026, the property has experienced a notable pattern of sanitation issues, with seven documented 311 service requests specifically related to garbage and debris, including multiple instances of loose garbage, yard waste, and bagged garbage. While all these recent complaints have been resolved through the appropriate channels, with some cases being marked as duplicates and others requiring no work, the recurrence of sanitation issues over a relatively short period raises some concerns about the building's maintenance practices.

The property's overall complaint history is relatively minimal, showing only two Department of Building Inspection complaints in the past seven years and one fire incident during the same period, though there are no details provided regarding the nature or severity of these incidents. The frequency of sanitation-related service requests during 2026, with six such complaints (including duplicates) between February and May, represents the majority of recorded complaints for this property in recent years. While the building appears to have had no major structural or safety concerns reported through official channels, the consistent pattern of garbage-related complaints suggests an ongoing maintenance challenge that has required regular intervention by city services.

Risk rating

How 551-555 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.

Neighborhood percentile

Out of 684 buildings in this neighborhood, 390 are predicted to be safer.
