Rent & eviction protection

Is 56 Patton 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.

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 56 Patton Street in Bernal Heights is a two-unit, two-story multi-family residential building constructed in 1909, currently owned by Patti Anne Fahey. The building has undergone several significant modifications over the past two decades, with the most recent notable work including a 2015 ground floor interior remodeling project that added a one-hour exit hallway and replaced a wooden beam with a steel beam in the garage. In 2012, there were efforts to convert a storage garage into an office and art studio, including adding a half-bath and two new windows, as well as modifications to accommodate parking for a second car. The property has also seen various infrastructure improvements, including a garage door installation in 2009 and electrical panel replacement with conduit repair in the same year.

The building's maintenance and compliance history shows active management, with multiple permits filed and completed for various remodeling projects, though some earlier permits from 2001-2003 did expire. Recent activity around the property has primarily involved parking-related issues, with multiple 311 calls regarding illegal parking, including sidewalk parking and driveway blockages between 2019-2024. There have been occasional reports of noise and waste collection issues, with the most recent noise complaint filed in February 2024 and a missed trash collection report from September 2021. The property has had minimal safety incidents reported, with only one fire-related incident recorded as an assist to police or other governmental agency, and no civilian injuries associated with any incidents on record.

Risk rating

How 56 Patton 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
57thpercentile

Out of 1276 buildings in this neighborhood, 549 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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