Rent & eviction protection

Is 414-416 42Nd 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 414-416 42nd Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1928 and classified as a Flats & Duplex building, it is currently owned by Kam Tat & Oy Wah Lau Rvc Tr. The building's permit history shows several significant renovations in the late 1990s, including construction work completed in 1998 that added two bedrooms, a laundry room, storage room, and half bathroom, as well as modifications to the kitchen and bathroom involving sheetrock and cabinet changes. An earlier permit from 1996 indicates completion of reroofing work. More recently, in 2013, a street space permit was issued for the property.

The building has experienced ongoing issues with parking violations in the surrounding area, particularly in 2024, with eight documented cases of driveway blocking between October and December 2024, all resulting in citations, though one case could not be validated. A single case of sidewalk parking was reported and resolved in October 2024. Earlier in December 2023, there was a report of a faded street cleaning sign, which was subsequently addressed. In terms of tenant buyouts, there is one recorded instance at 436 42nd Avenue in May 2024, involving a payment of $30,000 to one tenant.

Risk rating

How 414-416 42Nd 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
61stpercentile

Out of 1040 buildings in this neighborhood, 406 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
