Rent & eviction protection

Is 839 Leavenworth 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 1911
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.

Built 1911
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

839 Leavenworth Street is a 5-story, 50-unit multi-family residential building constructed in 1911, currently owned by Sic-mcm 839 Leavenworth Str. The property has undergone significant upgrades and renovations in recent years, including a $83,200 fire alarm system upgrade in 2024 (currently filed) to comply with 2022 codes, and multiple unit renovations between 2016-2020 encompassing kitchen and bathroom improvements in units 102, 201, 303, 304, 307, 508, and 509, with corresponding electrical and plumbing updates. The building has experienced recurring issues with its elevator system, with the most recent complaints in August 2024, and has had multiple fire alarm system-related complaints and violations, including an open violation for sleeping area requirements from November 2023. Historical complaints between 2005-2018 indicated various safety concerns, including issues with fire escapes, handrails, egress obstructions, and a notable 2014 complaint about flooding through the roof causing mildew and mold.

The property has been the subject of illegal short-term rental activity, with violations related to a fraudulent registration that was ultimately abated. Recent building-related complaints include water leakage issues in 2022 and construction-related disturbances in 2020. There is an active permit application for adding two new accessory dwelling units to the rear portion of the basement. Fire safety remains a recurring concern, with documented issues regarding extinguishers and sprinkler systems between 2015-2022, and multiple violations/corrections needed for alarm systems. The building's surrounding area has experienced various maintenance and sanitation challenges, as evidenced by numerous 311 calls for garbage, debris, and encampments between late 2024 and early 2025.

Risk rating

How 839 Leavenworth 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
16thpercentile

Out of 448 buildings in this neighborhood, 376 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
