Rent & eviction protection

Is 144 Winfield 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 1908

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 1908
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 144 Winfield Street in Bernal Heights is a two-unit, single-story multi-family residential building constructed in 1908, currently owned by the Ackerman 1995 Living Trust. The building has undergone a few significant renovations over its lifetime, most notably a completed horizontal addition in 1998, for which a permit was renewed in 1999. Earlier improvements from 1986 included updates to the flue system, kitchen cabinets, and interior repairs and painting, though these permits are now expired.

Recent activity around the property has primarily involved public infrastructure and parking issues. There are currently several open or recently closed cases regarding parking enforcement and tree maintenance. Most notably, there is an open case from February 2024 regarding tree roots damaging the sidewalk, and a recently reported blocked sidewalk issue from December 2024. The area has experienced recurring problems with abandoned vehicles, with multiple reports between 2021 and 2024, though most were resolved promptly, either through the vehicles being removed or the situation resolving itself. A tree maintenance issue from December 2021 involving a hanging limb was successfully resolved. While the building itself has not had any major reported issues or violations in recent years, the surrounding area has experienced ongoing parking and tree-related concerns that may impact resident access and maintenance.

Risk rating

How 144 Winfield 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
60thpercentile

Out of 1276 buildings in this neighborhood, 510 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
