Rent & eviction protection

Is 346 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
25 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

346 Leavenworth Street is a 5-story, 25-unit multi-family residential building constructed in 1924, currently owned by 346 Leavenworth St LLC. The property has undergone significant maintenance and upgrades in recent years, with active permits as of late 2024 for fire alarm system upgrades to comply with current codes (including low frequency sounders in sleeping areas) and completed plumbing work involving sewer spot repairs in March 2024. The building has seen substantial unit improvements between 2019-2024, including multiple bathroom and kitchen remodels, electrical upgrades, and washer/dryer installations in various units, demonstrating ongoing investment in maintaining and modernizing the property.

Recent fire safety concerns have emerged as a priority, with violations issued in 2024 related to sleeping area requirements and issues with standpipe systems, though some earlier violations from 2024 (including alarm systems and extinguishers) were resolved promptly. There have been some maintenance and safety issues noted in housing complaints over the years, including a 2023 complaint about window bars and emergency egress concerns, though most recent complaints have been resolved. Historical records from 2002-2009 show various violations and complaints including elevator issues, intercom problems, and interior surface repairs, all of which were eventually addressed. The building's location in the Tenderloin neighborhood has resulted in multiple 311 calls for street cleaning and maintenance issues in the surrounding area, with recent reports in early 2025 primarily relating to debris and waste removal.

Risk rating

How 346 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 172 buildings in this neighborhood, 134 are predicted to be safer.
