Rent & eviction protection

Is 2870-2878 Harrison 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 1908
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 1908
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, 9-unit apartment building at 2870-2878 Harrison Street, constructed in 1908, has undergone several significant improvements and encountered various challenges over the years. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $40,000, achieving compliance with San Francisco's seismic safety requirements. In September 2019, the building experienced fire damage requiring repairs to wood and siding at the side elevation, which was subsequently completed. The building underwent extensive renovations between 2013-2015, including the installation of multiple fireplaces, furnaces, and comprehensive upgrades to bathrooms and kitchens. Multiple building complaints from 2013-2014 raised concerns about construction practices, including lead paint removal procedures and work being conducted outside permitted hours. More recently, the building faced recurring issues with fire safety equipment, as evidenced by annual fire extinguisher complaints from 2020-2024, though these were generally resolved promptly.

The property has also been subject to inspection-related requirements, including several instances requiring final inspections and permit revisions between 2013-2015. A significant cluster of violations was documented in October 2003, addressing various safety and maintenance issues such as security requirements, lead paint hazards, and inadequate lighting, though these were all abated by February 2005. The building's ownership has been attentive to regulatory requirements, demonstrated by the successful completion of mandatory seismic retrofitting and prompt responses to inspection requirements. Recent 311 calls (2024-2025) primarily relate to external issues such as parking violations and street cleaning needs, rather than building-specific concerns.

Risk rating

How 2870-2878 Harrison 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 2380 buildings in this neighborhood, 2237 are predicted to be safer.
