Rent & eviction protection

Is 740 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 1924
2 or more units
15 units
Property type
Multi-Family Residential
Zoning
RC4
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1924
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 740 Leavenworth Street building is a 15-unit, 4-story multi-family residential apartment building constructed in 1924 and currently owned by Dyn Tr. The property has undergone several significant safety system upgrades in recent years, most notably a complete fire alarm system upgrade in February 2024 and modifications to the fire alarm system in June 2023 to meet current safety codes, including the installation of low-frequency sounders in sleeping areas. However, there are currently open violations related to sleeping area requirements as of December 2023, while a previous sprinkler system violation from October 2023 has been abated.

The building's maintenance history shows regular attention to essential systems, with a new steam heating boiler and domestic hot water equipment installed in 2014, following earlier improvements including a rooftop repair completed in 1988 and a parapet safety program completion in 1987. The property has undergone routine housing inspections over the years (most recent in 2017), with several fire safety issues identified and subsequently addressed between 2010 and 2016, including fire escape ladder repairs, alarm panel certification, and smoke detector installations. While there have been multiple fire and building violations in the past, most have been promptly addressed, with the exception of the recent sleeping area requirement violation. The property has experienced some ongoing maintenance issues, as evidenced by various 311 calls for street cleaning and debris removal in the vicinity, most recently in October 2024, though these are not directly related to building maintenance.

Risk rating

How 740 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
56thpercentile

Out of 448 buildings in this neighborhood, 197 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.
