Rent & eviction protection

Is 1925-1927 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 1923

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.

Annual rent increase cap

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 property at 1925-1927 Lyon Street is a two-unit, two-story multi-family residential building constructed in 1923, currently owned by 1925-1927 Lyon Street LLC. The building has experienced several significant maintenance and code compliance issues over the past decades, with the most concerning period occurring between 2008-2010 when multiple violation notices were issued regarding unpermitted construction work, including electrical and plumbing installations, and hazardous conditions. These violations included improperly installed plumbing fixtures, a tankless water heater, electrical wiring work, and various appliances installed without permits. While many of these violations were eventually addressed through permits and corrections, they indicate a period of substantial maintenance challenges.

More recent history shows ongoing concerns with the property, including a mold complaint in 2017, and repeated issues with unpermitted short-term rentals, with violations recorded in 2011 and subsequently. The building's maintenance history shows some structural and systems upgrades, including completed kitchen and window renovations in the early 2000s, and a failed foundation upgrade and remodel project proposed in 2007 valued at $250,000. The property has also been subject to various parking enforcement actions in recent years, primarily related to driveway blocking incidents recorded between 2019-2023. Most concerningly, there are two recent fire code violation notices from October 2021 and November 2024, though the specific nature of these violations requires further investigation. The building's historical records indicate a pattern of deferred maintenance and compliance issues, though many of these have been addressed through subsequent permits and corrections.

Risk rating

How 1925-1927 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 963 buildings in this neighborhood, 212 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.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
