Rent & eviction protection

Is 1827-1829 Judah 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 1939

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 two-unit residential building at 1827-1829 Judah Street in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1939, currently owned by the Lam Family Trust. The property underwent significant renovation in 2005-2006, including substantial additions and conversions of living spaces on both floors, with work totaling over $85,000. However, this construction period was marked by serious safety concerns, including a stop work order in August 2006 due to unauthorized continued work and the presence of temporary shoring at the east side and back of the building, which was associated with a partial collapse. Multiple violations were documented during this period, though these issues were officially abated by September 2006.

More recently, there have been several maintenance and quality-of-life issues documented through 311 calls, including multiple reports of abandoned debris (such as mattresses and appliances), pavement defects, and instances of graffiti. The most frequent recent issues relate to street maintenance and parking violations documented between 2022 and 2024. While these recent issues don't indicate any structural concerns, they do reflect ongoing property maintenance and neighborhood quality matters. The building's major systems underwent some updates during the 2005-2006 renovations, including electrical work in both the basement addition and rewiring of the basement, suggesting some modernization of the original 1939 systems.

Risk rating

How 1827-1829 Judah 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
48thpercentile

Out of 814 buildings in this neighborhood, 423 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
