Rent & eviction protection

Is 1243-1247 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 1908

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-unit residential building at 1243-1247 Leavenworth Street in Nob Hill, owned by Chuen Mei Wong Family Trust, was constructed in 1908 and is classified as a Flats & Duplex building over three stories. The property's most significant historical renovation occurred in late 2000, when comprehensive updates were undertaken to remodel kitchens and bathrooms, along with addressing dry rot issues and clearing termite reports, with a total project cost of $40,000. More recently, there have been several maintenance and property-related issues in 2023-2025, including multiple reports of garbage and debris (both loose items and abandoned furniture) on the street, repeated illegal parking complaints, and incidents of illegal postings and graffiti on public property. A noise complaint regarding construction on private property was filed in October 2023, and records show a routine housing inspection complaint from 2003 that was abated in 2007. The building's documented history shows regular street maintenance issues typical of urban environments, though no significant safety incidents have been reported, and there is no record of civilian injuries or fire incidents associated with the property.

Risk rating

How 1243-1247 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
75thpercentile

Out of 1125 buildings in this neighborhood, 281 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.

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.

Building age

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