Rent & eviction protection

Is 19 Moss 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 before 1979
Built 1923

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 1923
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 19 Moss Street property, owned by the William Curry Living Trust, is a two-story multi-family residential building constructed in 1923, containing 4 units in the South of Market neighborhood. Recent concerning events include a significant incident in January 2023 involving hallway ceiling collapse attributed to water damage, with mentions of asbestos, gas leaks, and mold throughout the unit. The building has a notable history of safety and maintenance issues, particularly evident in the 2003-2004 period when multiple violations were recorded, including problems with stairway storage, guardrails, fire safety equipment, and smoke detectors, though these were all officially abated by April 2004. More recent fire safety concerns have been documented, with three violations between 2021-2024 related to alarm systems and sprinkler systems, though these were either corrected or resolved through violation issuance.

The building's recent history has shown recurring maintenance challenges, as evidenced by multiple 311 calls in 2024 reporting issues such as sewage backup, garbage and debris problems, and encampments in the vicinity, with some calls specifically noting human waste or urine in the area. Fire department responses to the building have been primarily for non-fire-related incidents, including elevator rescues, false alarms, and service-related calls, with no civilian injuries recorded in any of these responses. In addition to the documented fire violations, the building has experienced various service and infrastructure-related issues, including a 2023 violation regarding sprinkler system maintenance (noted at a different address, 1049-1053 Howard Street). The property has also undergone several routine safety inspections over the years, with the most recent inspection activity occurring in 2024.

Risk rating

How 19 Moss 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
44thpercentile

Out of 430 buildings in this neighborhood, 241 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
