Rent & eviction protection

Is 62-64 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 1911
2 or more units

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 1911
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 three-story multi-family residential building at 62-64 Moss Street, constructed in 1911, is a four-unit structure owned by Leffers Tr and has undergone several significant improvements over the past decade. Most notably, between 2017-2018, a legal basement unit was created (including seismic upgrades, new columns, and footings), and comprehensive fire safety improvements were implemented, including the installation of a fire sprinkler system in the basement, a sprinkler monitoring system, and related electrical work. The building has also received substantial plumbing upgrades, with the installation of on-demand hot water heaters for units 62, 64, and 64A, and various electrical improvements including new circuits and a 100-amp subpanel installation.

The property has a history of addressing safety and compliance issues, with several building violations from 2003-2010 that have since been resolved, including concerns about ventilation, egress pathways, electrical outlets, and fire safety. Recent fire safety complaints from 2010, 2014, and 2021 regarding alarm systems and blocked exits were all promptly corrected. The building experienced one instance of water heater flue issues in 2011 that required correction, and underwent routine safety inspections in 2009 and 2010. More recently, there have been multiple 311 calls between late 2024 and early 2025 regarding street cleaning and debris issues outside the building, though these are not directly related to the building's internal conditions.

Risk rating

How 62-64 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
86thpercentile

Out of 430 buildings in this neighborhood, 60 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
