Rent & eviction protection

Is 659-661 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.

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 659-661 18th Avenue is a two-unit, two-story multi-family residential building located in the Central Richmond neighborhood, owned by the Young Family Trust and constructed in 1922. The building's maintenance history includes significant repairs completed in 2008, including the replacement of rotted stairs in the south light well area and remediation of dry rot on approximately 40 square feet of walls, as well as a reroofing project completed in 2011 at a cost of $6,000.

In recent years, the property has faced some environmental challenges, particularly between late 2018 and 2022, with multiple reports of medical waste (specifically needles) discovered in the vicinity around November 2018, and some graffiti incidents recorded on the sidewalk in front of the property in 2022 and 2023. More recent exterior concerns include two parking enforcement incidents in 2024 (one for an abandoned vehicle and one for parking on the sidewalk). The property has also experienced recurring sidewalk maintenance issues, with general cleaning requests in February 2022 and August 2022, though these appear to have been resolved promptly. While the building has required various repairs over the years, the historical permit records indicate that necessary maintenance work has generally been completed properly, with no outstanding permits or major structural concerns currently on record.

Risk rating

How 659-661 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
72ndpercentile
