Rent & eviction protection

Is 680-684 Hayes 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.

Built 1885
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 680-684 Hayes Street in Hayes Valley, owned by Tony H Lee and Sunny Yousun, is an 1885 Victorian structure currently consisting of three units. The property has undergone several significant renovations and faced various compliance issues over the years. Most notably, in 2017, the building underwent substantial kitchen renovations in units 682 and 684, including cabinet replacements, new countertops, appliances, and related electrical and plumbing work, with the work valued at $30,000. This renovation followed a building complaint from 2019 alleging unauthorized work and construction noise during late hours. The building was previously cited for multiple violations in 2008, including issues related to stairs, handrails, fire safety, and security requirements, though these were all abated by April 2009. Earlier improvements include a complete reroofing in 2004 and various routine safety inspections over the years.

More recent history shows a pattern of maintenance and compliance activities, with the most notable being frequent reports of overflowing garbage and debris at the property in late 2024 and early 2025, with multiple Recology calls being logged between December 30, 2024 and January 14, 2025. The building has also experienced several routine inspections by Housing Inspection Services over the years (2003, 2011, 2018) and multiple complaints regarding various issues between 2016 and 2019, including construction noise complaints, power washing concerns, and a complaint about misrepresented bedroom counts in 2019. While the building has experienced various maintenance issues and compliance matters, most violations and complaints have been addressed and resolved, with no active violations currently on record.

Risk rating

How 680-684 Hayes 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.
