Rent & eviction protection

Is 1309 Silver Ave 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 1975
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1975
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 property at 1309 Silver Avenue in the Portola neighborhood is a one-story, two-unit residential building constructed in 1975, currently owned by the Lum Marital Trust. The building has a documented history of maintenance, including a reroofing project completed in 1995, though this permit has since expired.

In recent years, particularly throughout 2024, the area surrounding the building has experienced recurring issues with street cleanliness, with multiple reports of garbage and debris (including bagged items, loose garbage, and furniture) requiring intervention from Recology and the Department of Public Works. There were also several infrastructure concerns in late 2024, including a report of sidewalk defects and graffiti on a pole, though records indicate the sidewalk defects did not meet dimensional requirements for enforcement action. A sewer odor complaint was logged in July 2024, which was addressed by PUC Sewer Operations. The building's permit and planning records show a prior proposal for three dwellings with apartment conversions at 1301 Silver Avenue, which received CEQA clearance, though it is not clear if this directly relates to the current address or was ever implemented.

Risk rating

How 1309 Silver Ave'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
79thpercentile

Out of 255 buildings in this neighborhood, 54 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
