Rent & eviction protection

Is 316-318 Castro 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 1977
2 or more units

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 1977
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 Wong Family 2016 Trust owns this two-unit residential building located at 316-318 Castro Street in Corona Heights, which was constructed in 1977 as a two-story flats and duplex structure. Recent maintenance work was performed in April 2018, when living walls were installed in the rear yard at a cost of $500. A building complaint was filed in September 2017 regarding unpermitted construction of a rear deck, though this issue is currently listed as not active.

The property has experienced several recent infrastructure issues, with two notable plumbing-related incidents in 2024: an April flooding incident that required plumbing intervention and a currently open complaint regarding a missing side sewer vent cover. In the past, the property has faced recurring challenges with graffiti, particularly between 2022 and 2024, affecting both the building's sidewalk and public areas. While most of these cases were resolved through various means, including owner intervention and city inspection, a significant backlog of complaints was generated during the COVID pandemic due to a temporary suspension of graffiti enforcement. The building's location also necessitated one parking enforcement action in March 2022, resulting in the towing of a vehicle blocking the driveway.

Risk rating

How 316-318 Castro 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
70thpercentile
