Rent & eviction protection

Is 7-19 Leroy Pl 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
2 or more units

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 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 6-unit, 3-story residential building at 7-19 Leroy Place in Nob Hill, built in 1908, has experienced several significant maintenance and safety issues over the past few years under the ownership of John E Wai 1981 Living Trust. Most recently, in July 2026, there were serious concerns about illegal construction activities involving multiple contractors on-site, with allegations of permit violations and extreme disruption to residents. This followed multiple complaints throughout 2024-2026 regarding broken windows, persistent plumbing problems including severe wastewater leaks and infrastructure issues affecting multiple floors, and concerns about pest infestations. The building's violation history shows several Notices of Violation (NOV) in 2026 related to window maintenance and inspection access requirements, though these violations are currently listed as not active. Additionally, there were three false alarms from the fire alarm system in June 2024, though no injuries or fatalities were reported, and all 311 service requests have been appropriately closed or resolved through the city's systems. The property has shown recent patterns of compliance with some issues being promptly addressed, though the pattern of violations and complaints prior to 2026 suggests ongoing challenges with maintenance and resident communication.

Risk rating

How 7-19 Leroy Pl'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
