Rent & eviction protection

Is 1803 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.

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

Just-cause eviction

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 Wong/Liang Family Trust owns this 2-story, 5-unit multi-family residential building located at 1803 Judah Street in the Central Sunset neighborhood. Built in 1925, the property has undergone several significant improvements over the years, with the most substantial recent work occurring between 2021-2022 when a garage was converted into a studio ADU (Accessory Dwelling Unit) at a cost of $40,000. This renovation included comprehensive updates to the building's systems, featuring new plumbing installations, complete electrical rewiring, and an upgraded 400-amp electrical service with multiple meter sockets. The ADU project also involved important safety enhancements, including the installation of a fire sprinkler system with additional sprinklers in the new unit.

The building's maintenance history shows regular attention to basic infrastructure, including two complete roof replacements (1990 and 2013) and the installation of a voluntary partial sprinkler system in the garage and storage area in 1989. A routine housing inspection in 2001 was completed without any noted issues. More recently, the property has experienced some urban maintenance challenges typical of the area, with multiple 311 reports in 2024 primarily related to street cleaning and parking enforcement matters. These included several instances of vehicles blocking driveways, which resulted in citations being issued. While there was one recorded fire incident involving a malfunctioning smoke detector, there were no civilian injuries associated with this event. The building's records indicate substantial investment in safety and modern amenities, particularly during the recent ADU conversion project, while also showing ongoing responsiveness to both routine maintenance needs and regulatory requirements over the years.

Risk rating

How 1803 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
26thpercentile

Out of 814 buildings in this neighborhood, 602 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
