Rent & eviction protection

Is 1140-1144 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 1911

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 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

The property at 1140-1144 Leavenworth Street is a three-unit, three-story multi-family residential building located in San Francisco's Nob Hill neighborhood. Built in 1911 and currently owned by Leung Kam Lun & Windy Ngan, this flats and duplex-style building has undergone significant recent renovations to improve tenant living conditions. In late 2020 and early 2021, substantial upgrades were completed, including the replacement of old lath and plaster with sheetrock, kitchen and bathroom remodels, electrical system improvements on the third floor, and the addition of new lighting and outlets throughout. A new washer and dryer was also installed during this renovation period, with all work properly permitted and completed at a cost of approximately $49,000.

The building's maintenance history shows attention to code compliance, with records indicating multiple routine housing inspections between 1999 and 2010, and the resolution of several previous violations from 2002 related to inadequate lighting in the rear passageway and lack of a utility shut-off tool, which were promptly abated within two weeks. The property has maintained an active response to building upkeep and safety requirements, as demonstrated by the 1986 permits for code compliance work. Recent external environment issues near the property have been documented through multiple 311 calls between 2021 and 2024, primarily related to street cleaning and parking violations, though these incidents were generally addressed promptly by city services. The most recent building improvements and consistent resolution of past violations suggest a proactive management approach to building maintenance and tenant safety, with no active building violations currently on record.

Risk rating

How 1140-1144 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
82ndpercentile

Out of 1125 buildings in this neighborhood, 202 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
