Rent & eviction protection

Is 320 Woolsey 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 1920

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 1920
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 320 Woolsey Street is a two-unit, two-story multi-family residential building located in the Portola neighborhood, constructed in 1920 and classified as Flats & Duplex. The building's maintenance history includes two significant structural improvements: a reroofing project completed in 1991 and repairs to the outside stairs completed in 1988, both indicating attention to fundamental building safety and maintenance requirements.

The recent history of the property, particularly from 2023 to 2024, shows a notable pattern of parking-related issues in the vicinity, with multiple reports of illegal parking, driveway blocking, and sidewalk obstruction. Between July 2023 and September 2024, there were at least eight documented incidents of parking violations, with varying responses from enforcement officers, including some cases where officers were unable to locate the offending vehicles, and at least one instance where the violation was confirmed. There have also been several reports of street cleanliness issues, including instances of garbage and debris on the property grounds or public areas, with the most recent incidents occurring in August and November 2024, including reports of a refrigerator appliance and other loose debris. While these external environmental issues and parking challenges are noteworthy, it's important to note that the building's fundamental structure appears to have been maintained through the documented repairs from previous decades.

Risk rating

How 320 Woolsey 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
67thpercentile

Out of 255 buildings in this neighborhood, 84 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
