Rent & eviction protection

Is 976-978 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.

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 1909
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 976-978 Harrison Street is a two-story, four-unit multi-family residential building constructed in 1909, currently owned by Raul and Denise Arriaza. The building has undergone several significant renovations and repairs over the past two decades. Notable improvements include a kitchen remodel in 2011 at unit #976 ($6,500), dry rot repair of the sun room in 2009 ($5,000), and various structural modifications in 2000 including garage improvements ($13,000) and the addition of a stair connection between units ($20,000). In 2012, there was a concerning incident involving carbon monoxide detector activation when using the stove, attributed to high pilot settings, though this was quickly addressed. The building experienced multiple fire safety violations in 2003, including issues with egress obstruction, fire extinguishers, and combustible storage, all of which were abated by December 2003. There was also a period of construction without proper permits in 2009, though this was resolved.

The property has a history of maintenance and safety inspections, including routine safety inspections in 2008 and 2003, and an unsafe building complaint in 2000 regarding sidewalk conditions that required attention and permits. More recently, there have been several 311 calls related to street cleaning and sidewalk maintenance, with the most recent general cleaning requests occurring in May 2024. A single fire alarm activation was recorded, though it was determined to be unintentional with no fire or injuries. The building's recent history shows proper attention to resolving maintenance issues, though the frequency of street cleaning-related calls suggests ongoing challenges with external maintenance in the immediate vicinity of the property.

Risk rating

How 976-978 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

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
85thpercentile

Out of 430 buildings in this neighborhood, 64 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
