Rent & eviction protection

Is 1914 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 1885

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 1885
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 two-unit, single-story multi-family residential building at 1914 Lyon St in Pacific Heights was constructed in 1885 and is currently owned by the Lefkos B Aftonomos Revocable Trust. The property has undergone several significant improvements over the past few decades, with the most recent major work completed in February 2024 comprising the replacement of multiple windows and patio doors, at a cost of $58,370. Two roofing projects were completed in 2021, totaling approximately $39,600, and earlier improvements include deck repairs and vinyl siding installation in 2002, kitchen remodeling in 1996, and historical roofing work in 1992.

The building's recent maintenance history shows consistent upkeep, with the most notable recent activities being the substantial window and door replacement project and two separate roofing projects in 2021. The property has been subject to various 311 calls primarily related to street issues, parking concerns, and some urban maintenance matters between 2018 and 2024, though these incidents appear to be more related to the street and public areas rather than the building itself. Past improvements to the building include structural and aesthetic upgrades, with particular attention paid to maintaining the property's exterior and infrastructure, including both front street-facing elements and rear/side improvements not visible from the street.

Risk rating

How 1914 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
99thpercentile

Out of 963 buildings in this neighborhood, 10 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 floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
