Rent & eviction protection

Is 825-827 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.

Built 1890

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 1890
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 825-827 Hayes Street is a two-unit, two-story multi-family residential building located in the Alamo Square neighborhood, constructed in 1890 and currently owned by the Robert Alonso 2013 Trust. The building has undergone several significant renovations between 2008 and 2012, with the most substantial work occurring during 2008-2009 when major updates were implemented across both units. These improvements included comprehensive bathroom and kitchen remodels in both units, featuring new fixtures, cabinets, and appliances; complete electrical system upgrades with new 200-amp service installations and subpanels; plumbing modifications including new house trap installations; and various other interior improvements such as sheetrock and lighting updates. A bathroom renovation permit from 2008 was notably canceled in 2009 but was successfully completed under a new electrical permit.

In recent years, the property has had minimal maintenance issues, with only four 311 calls recorded in 2020-2021, none of which were related to the building's condition or resident safety. These calls primarily concerned exterior issues such as illegal postings, noise, and street/sidewalk cleanliness matters that were promptly resolved by city agencies. The most recent building permit on record is from 2012 for bathroom and kitchen improvements, suggesting that there have been no major structural modifications or system upgrades required since that time. The comprehensive renovation work completed between 2008-2012, which included both units' bathrooms and kitchens, electrical systems, and plumbing infrastructure, indicates that the building received significant modernization during that period, though more recent regular maintenance history is limited.

Risk rating

How 825-827 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.

Neighborhood percentile
97thpercentile
