Pacific Heights, SF 94115 1007007 5 units · 3 fl · 1907

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1903-1905 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 1907
2 or more units

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.

Built 1907
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 1903-1905 Lyon Street property is a 3-story, 5-unit multi-family residential building with ground-floor retail space, constructed in 1907 in San Francisco's Pacific Heights neighborhood. The building's records show several notable events, most significantly a series of housing code violations in December 2007 that were all addressed and abated by January 17, 2008. These violations included safety issues such as the need for fire extinguishers, security concerns regarding self-closing doors, and matters related to gas meter instructions and shutoff tools. The building experienced three fire-related incidents in recent history, though none resulted in civilian injuries or significant damage, with causes ranging from unintentional system activations to good intent calls. A building permit for street space usage was issued in 2013 for a nominal cost of $1.

In recent months (from August to November 2024), there have been multiple reports and complaints in the vicinity of the building, primarily related to parking issues such as blocked driveways and abandoned vehicles, as well as some street maintenance matters. Three encampment-related incidents were reported near the property in September 2024, though all were marked as "Unable to Locate" by responding agencies. Several illegal posting incidents and one case of overflowing city garbage cans were also noted in the area during this period.

Risk rating

How 1903-1905 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
38thpercentile

Out of 963 buildings in this neighborhood, 597 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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
