Rent & eviction protection

Is 757 Bacon 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.

Built before 1979
Built 1910

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1910
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 multi-family residential building located at 757 Bacon Street in the Portola neighborhood, owned by Kelvin Y Wong, has a documented history of unauthorized construction and permit violations spanning back to 2004 and most recently in 2024. The 1910 flats/duplex structure has experienced recurring issues with unauthorized deck modifications, including a current active violation from June 2024 regarding an improperly enclosed rear deck and unpermitted stairs installation, which follows a similar pattern as a 2004 incident that resulted in a completed permit to remove illegal enclosures (2004-1206-0777). The building's history also includes a completed reroofing project from 1991, and notable enforcement actions from 2004 that addressed several unauthorized construction attempts, including an illegal rear addition measuring approximately 6' x 12'.

The property has generated multiple 311 calls in early 2025, primarily related to parking violations and debris issues, with several resolved citations for illegal parking and sidewalk use. While these recent incidents indicate some neighborhood maintenance challenges, they are external to the building itself. A 2005 fire complaint regarding weeds and grass was ultimately found to have no merit. The building is subject to ongoing monitoring fees under San Francisco Building Codes, reflecting its history of permit non-compliance. The owner's recent permit filing in October 2024 appears to address previous violations, though the status remains filed as of October 2023.

Risk rating

How 757 Bacon 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
85thpercentile

Out of 255 buildings in this neighborhood, 38 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
