Rent & eviction protection

Is 632-634 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.

Built 1919

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.

Built 1919
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 two-unit residential building at 632-634 18th Avenue in the Central Richmond neighborhood, owned by Wong Lvg Tr, is a 2-story property constructed in 1919. The building underwent significant modifications in the early 2000s, with building permits showing a horizontal addition project initiated in 2002 (valued at $150,000) to formally create the two-unit structure, though this permit ultimately expired. This work continued in 2006-2008 with associated electrical work including the installation of two kitchens, four bathrooms, general lighting, and two new electrical panels, with costs totaling approximately $50,000. More recent building concerns include a documented heating system failure in December 2022 that took until March 2023 to resolve, and a complaint from 2013 regarding unauthorized construction work and debris issues affecting neighboring properties, though the resolution status is indeterminate.

The building's more recent history shows ongoing maintenance and operational concerns, particularly in 2024, with multiple 311 calls regarding parking violations (including sidewalk parking and driveway blocking), flooding issues, and garbage problems. There is also an open noise complaint from May 2023 regarding mechanical equipment. The property has been involved in various street space and electrical permits over the years, with the most recent significant infrastructure work appearing to be completed around 2007, including the installation of a garage door opener. The building's permit and complaint history suggests a pattern of both authorized improvements and unauthorized modifications, with particular attention needed to the property's heating system maintenance and parking-related concerns in the immediate vicinity.

Risk rating

How 632-634 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
23rdpercentile

Out of 2250 buildings in this neighborhood, 1732 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
