Rent & eviction protection

Is 1341-1343 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 before 1979
Built 1900
2 or more units
2 units

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 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 2-unit residential building at 1341-1343 Lyon Street in Lower Pacific Heights, constructed in 1900, has undergone significant improvements and faced various challenges over the past two decades. The property has seen substantial renovation work between 2013-2021, including a $178,000 interior remodel with kitchen replacements and bathroom additions, deck and stair replacements, foundation upgrades with reinforced concrete, and roofing work costing $17,860. Major plumbing and electrical systems were updated in 2013-2014, including new waste and vent pipes, water systems, tankless water heaters, and complete rewiring of both units.

The building has a history of maintenance issues, particularly evident in complaints from the early 2000s, including plumbing failures, electrical problems, and ceiling damage. Notably, there was a serious incident in 2003 when a 12-foot ceiling section fell, allegedly containing asbestos. Several complaints from 2005-2006 indicated ongoing plumbing and electrical system deficiencies. The most recent significant maintenance activity was the 2021 reroofing project, though a raw sewage leak complaint from 1996 remains listed as active. Recent 311 calls in 2024 have primarily concerned street-level issues, including garbage debris and abandoned items, suggesting ongoing challenges with building surroundings. Historical tenant buyouts are recorded for the nearby address 1333 Lyon Street in March 2020, totaling $50,100 for three tenants.

Risk rating

How 1341-1343 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
78thpercentile

Out of 670 buildings in this neighborhood, 147 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
