Rent & eviction protection

Is 1330 Union 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
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 23-unit, three-story multi-family residential building at 1330 Union Street in Russian Hill, constructed in 1908, is currently facing several significant issues that impact resident safety and comfort. Most notably, there is an active complaint from July 2024 regarding extensive visible mold inside a ground floor unit (Apartment 1) due to rainwater intrusion, with reports indicating lack of timely landlord response to remediation requests. The building has multiple current fire safety concerns, including open violations from 2024 regarding the sprinkler system and roof collection/drainage system, as well as fire alarm system issues dating back to 2023. Recent inspections have documented problems with water damage, damaged ceilings and walls, and lead-based paint concerns that require attention. The property has undergone substantial unit renovations between 2016 and 2018, including comprehensive updates to Units 6, 20, and 22 featuring kitchen and bathroom remodeling, electrical upgrades, and the installation of modern appliances, though these improvements appear to have been completed without proper permitting for some work.

The building has a history of fire safety violations, with multiple citation patterns observed between 2017 and 2024 involving alarm systems, sprinkler/standpipe systems, and sleeping area requirements. While some previous violations (such as those from 2023 and 2024) have been abated, there remain open issues requiring resolution. The property has also experienced periodic maintenance challenges, as evidenced by boiler permit renewal issues in 2016 and 2020, and various 311 calls in 2023-2024 regarding sidewalk defects, garbage and debris, and tree maintenance. Recent fire system upgrades are underway, with an approved permit from February 2024 for upgrading the fire alarm system to current codes, though this work appears to address only part of the building's fire safety deficiencies.

Risk rating

How 1330 Union 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
6thpercentile

Out of 1133 buildings in this neighborhood, 1065 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
