Rent & eviction protection

Is 400 2Nd 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 1922

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 three-story, five-unit multifamily residential building at 400 2nd Avenue in the Inner Richmond, built in 1922, has undergone significant structural and safety improvements in recent years. Most notably, between 2023 and 2024, major foundation work was performed with permits totaling $35,000 for replacing beams, foundation repair, and interior post replacement. The building's fire safety systems have received substantial upgrades, including a $19,600 fire alarm system upgrade in 2023 to comply with San Francisco Fire Code requirements, following a history of fire safety concerns dating back to 2004-2005. The property has experienced multiple maintenance challenges, with complaints about heating issues and window problems in 2022-2023, as well as more recent concerns about work being performed without permits in early 2023. Historical records show previous significant events including water damage repairs in 2021 ($15,000), vehicle-related structural repairs in 2012 ($20,000), and a 2008 reroofing project ($19,500). The building has had several building code violations and complaints over the years, particularly related to fire safety and emergency egress systems, though most of these issues appear to have been resolved through subsequent repairs and upgrades. Recent 311 calls (2024) relating to the building's immediate vicinity have primarily concerned street cleaning and maintenance issues rather than direct building concerns.

Risk rating

How 400 2Nd 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
1stpercentile

Out of 1723 buildings in this neighborhood, 1706 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
