Rent & eviction protection

Is 457-463 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.

Built before 1979
Built 1907

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.

15+ years since occupancy
Built 1907
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 four-unit, two-story multi-family residential building at 457-463 Filbert Street in Telegraph Hill, owned by Wilbert Wong, was constructed in 1907 and has experienced several significant maintenance and safety-related issues over recent years. Most notably, in 2022, the building underwent multiple corrections in response to violations including handrail and guardrail installation at the back stairway, fire safety improvements, and repairs related to routine inspections that revealed various building code compliance needs. These improvements were documented through building permit #202210194719, which specifically addressed handrail and guardrail requirements. Earlier building concerns included a 2015 complaint about water runoff affecting neighboring properties and historical violations from 2006 regarding stair repairs and fire safety equipment, though these were all marked as abated.

The building's maintenance history shows a pattern of addressing essential repairs, with the most recent permit work completed in 2022 focusing on stair safety. Historical records from the 1990s and 1980s indicate plumbing fixture replacements and reroofing work were completed, demonstrating ongoing building upkeep over the decades. More recent concerns have been mostly limited to parking enforcement issues, with multiple complaints about driveway blocking recorded between 2021 and 2024, though these are not directly related to building maintenance or safety. Recent service calls from 2024 include reports of a water leak and parking issues, suggesting some persistent infrastructure challenges in the immediate vicinity of the building, while a general cleaning issue from March 2024 indicates regular maintenance needs in the area.

Risk rating

How 457-463 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

Lower risk — safer than most nearby

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

Typical — about average for the neighborhood

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

Higher risk — riskier than most nearby

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

Neighborhood percentile
16thpercentile

Out of 684 buildings in this neighborhood, 575 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
