This building has 4 novs (7y), at or below the Tenderloin average of 12.1.

Rent & eviction protection

Is 650 Ellis 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 1916
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1916
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 30-unit, 3-story apartment building at 650 Ellis Street, constructed in 1916, has undergone significant recent renovations and faced various maintenance challenges. Between 2021 and early 2023, multiple units (2, 5, 9, 11, 16, 18, and 26) received substantial updates including kitchen and bathroom renovations, washer/dryer installations, and electrical improvements, with Unit 5 being the most recently completed in January 2023. The building's fire safety systems have been a recurring concern, with a fire alarm system upgrade completed in 2020 to meet NFPA 72 standards, though subsequent violations for alarm system maintenance were noted in 2023. Significant historical issues include a period of serious water damage and ceiling leaks reported in 2019 in Unit 29, structural concerns noted in 2018 regarding contorted roof and floor, and multiple violations from 2011 related to heating, water damage, and various maintenance issues, though these were abated by August 2012.

The property has experienced ongoing maintenance challenges, with recent 311 calls in 2024 indicating issues with a damaged sewer vent cover, property damage potentially related to a tree, and sewage back-up discharge. Historical complaints from 2018 mentioned possible lead concerns in Unit 3's hallway tiles, while earlier violations from 2011 involved various issues including the need for repairs to tubs/showers, window frames, and fire safety equipment. The building's management has generally addressed permit requirements, as evidenced by multiple completed permits for unit renovations and infrastructure upgrades, including a common area washer/dryer upgrade and sewer lateral work in 2020. Fire safety remains a monitored area, with the most recent fire alarm-related complaint in July 2024 showing prompt correction, though a violation was issued in August 2023 related to alarm system maintenance.

Risk rating

How 650 Ellis 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
65thpercentile

Out of 172 buildings in this neighborhood, 60 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
