Rent & eviction protection

Is 511-515 Lyon 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 1900

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 1900
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 3-unit multi-family residential building at 511-515 Lyon Street, owned by the Kaleen J Wong Revocable Trust, is a 3-story flats and duplex building constructed in 1900 in the Park North neighborhood. The property has undergone several significant renovations and faced various compliance issues over its history. Most notably, in 2020, the building underwent a substantial renovation of the kitchen, dining room, powder room, and bathroom on the second floor, with associated plumbing and electrical work totaling $50,000, though this work initially generated a complaint about unpermitted construction during COVID-19. The building previously experienced multiple violations in June 2003 related to fire safety, lead paint hazards, and egress obstruction, though these were abated by July 2004. Earlier maintenance issues were documented in 1997-2002, including problems with a shower foundation, wall tiles, and carpeting, as well as deck repairs and a reroofing project in 2002.

The building's maintenance history shows regular updates to address safety and compliance concerns, including the installation of smoke detectors and proper fire safety equipment. In 2020, there was a tenant buyout reported at 513 Lyon Street for $57,200, affecting 3 tenants. Recent activities in the area (2023-2024) have primarily consisted of parking enforcement issues, with multiple citations issued for illegal parking, particularly involving a Jeep/Wrangler vehicle. The property's exterior maintenance has been generally addressed through various permits and inspections, with most historical violations having been resolved. Recent 311 calls (2023-2024) mainly relate to street cleaning and parking issues, rather than building-specific concerns, suggesting that major building systems and safety compliance are being actively maintained through regular inspections and permits.

Risk rating

How 511-515 Lyon 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
52ndpercentile

Out of 797 buildings in this neighborhood, 383 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age
