Rent & eviction protection

Is 321 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.

15+ years since occupancy
Built 1926
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 321 Judah Street is a two-story mixed-use building constructed in 1926, containing three residential units and ground floor commercial space, currently owned by 321 Judah St Avika LLC. The building has undergone several significant renovations and modifications over the past two decades, with the most recent major work being the conversion of part of the ground floor into a childcare facility in 2018-2019. This conversion included the installation of a fire alarm system, new children's plumbing fixtures, and related improvements, all properly permitted and completed. The building's maintenance history shows attention to structural integrity, including termite damage repairs in 2009, when foundation work was completed along with significant interior renovations including new central heating systems, bathroom installations, and electrical updates.

The building has experienced recurring sewer-related issues, with multiple documented sewage backup incidents between 2020 and 2022, all of which were resolved through municipal intervention. While these incidents suggest some ongoing challenges with the building's plumbing infrastructure, they were addressed through proper channels. The property was previously the subject of planning considerations regarding its mixed-use status, with proposals to convert it into a childcare center or modify its residential units, though earlier construction proposals from 2000 were withdrawn. The building's maintenance record shows regular upkeep, including reroofing work in 1993, various bathroom renovations, and infrastructure improvements, indicating ongoing investment in property maintenance and compliance with building codes.

Risk rating

How 321 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
