Rent & eviction protection

Is 243-249 Oak St 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 three-story, 12-unit multi-family residential building at 243-249 Oak Street in Hayes Valley, owned by David Johnson, was constructed in 1911 and has undergone several significant improvements and faced various maintenance challenges. Most notably, the building completed a mandatory soft-story retrofit in 2016-2017 (Tier 3) at a cost of $65,000 to $6,500, demonstrating compliance with seismic safety requirements. The property has experienced multiple maintenance issues between 2015 and 2024, including significant problems in late 2015 with broken windows, rodent infestations, and mold/mildew, followed by heating system failures and plumbing issues, all of which were subsequently resolved. In 2021-2023, there were recurring concerns about security, including malfunctioning doors and problematic windows, along with water damage and mold issues reported in various units. The building's systems have been maintained through various permits and repairs, including plumbing updates for water heaters (2016), sewer trap replacement (2015), and electrical work to address wiring concerns.

Recent activity includes a 2024 complaint regarding unpermitted construction work adjacent to the property and a common areas complaint from 2023, both of which were resolved. The building has had several fire safety inspections showing "No Merit" for various concerns between 2019-2022, including issues related to exit maintenance, electrical systems, and fire escapes. While there have been multiple 311 calls regarding the property and its surroundings, these are generally related to street cleaning and maintenance rather than building-specific issues. The building's historical records show proactive responses to violations and complaints, with most issues being promptly addressed and resolved, including three 2015 violations related to broken windows, plumbing, and heating systems, which were all abated by early 2016.

Risk rating

How 243-249 Oak St'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
4thpercentile

Out of 1027 buildings in this neighborhood, 986 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
