Rent & eviction protection

Is 117-119 18Th 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.

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 1913
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 117-119 18th Avenue is a two-story, 3-unit multi-family residential building located in the Lake -- The Presidio neighborhood, owned by Ronald Wong & Beverly C Cho. Built in 1913, this flats and duplex structure has undergone several significant maintenance updates over the years, with the most recent being a substantial $29,000 reroofing project completed in October 2022. This follows a pattern of regular roof maintenance, as documented by earlier roofing projects in 1998 and 1992, suggesting proactive upkeep of this critical building component. The building has also received other structural improvements, including the installation of siding on the rear elevator in 1983.

The property's service record includes three documented 311 calls. In February 2022, there was a customer callback related to the Rent Board that was resolved with confirmed payments. Earlier incidents included a street cleaning request for loose garbage in February 2021, which was promptly addressed by Recology, and a report of an abandoned GMC Suburban vehicle in August 2013, though this was resolved when authorities arrived to find the vehicle had already left the location. The building's maintenance and service record indicates regular upkeep and prompt response to issues as they arise, with no recent complaints or incidents that would significantly impact resident experience or safety.

Risk rating

How 117-119 18Th 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
75thpercentile

Out of 660 buildings in this neighborhood, 165 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.

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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
