Rent & eviction protection

Is 877 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 before 1979
Built 1900
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 1900
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 877 Hayes Street is a two-unit, two-story multi-family residential building located in the Alamo Square neighborhood, constructed in 1900 and currently owned by the John E Wai 1981 Living Trust. The building has undergone significant renovations and faced several challenges over the past few years. Most notably, in October 2021, the property was cited with multiple violations including hazardous conditions, security concerns, and plumbing issues, which were all officially abated by June 2024. Following these violations, substantial renovations were undertaken, including a comprehensive electrical system upgrade completed in June 2024 that involved new wiring, LED lighting, switches, outlets, and a new 100-amp subpanel, as well as front window replacements in early 2024.

The building's recent history shows a pattern of addressing serious maintenance issues, including repairs to stairs and compliance with various building codes. A retaining wall failure reported in December 2022 was resolved by May 2024. The property's permit history reveals several substantial renovation projects, particularly between 2022 and 2024, focusing on bathroom and kitchen remodels in both units, along with HVAC and plumbing updates. Notable improvements included the installation of new smoke/CO alarms and compliance with modern safety requirements. While there were earlier attempts at renovations in 2018-2019 that were cancelled or withdrawn, the recent completion of repairs and upgrades suggests a concerted effort to bring the building up to current standards, though the property experienced a period of vacancy and abandonment concerns between 2020-2021 as noted in multiple complaints.

Risk rating

How 877 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.
