Initial analysis

The property at 1359-1361 45th Avenue in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1915, currently owned by Linda Ao Guan. The building has undergone significant modifications and improvements since 2004, when a major horizontal addition was authorized to add a new unit (with a cost of $300,000) followed by additional work in 2007 to convert storage space to habitable rooms and install a fire sprinkler system with 91 sprinklers. During this period, several building violations and complaints emerged, notably including foundation concerns in 2006 that allegedly affected a neighboring property (1355 45th Avenue), which required multiple compliance efforts and was ultimately abated by 2012. Additional violations in 2009 concerned expired permits and non-compliance with notices, though these were also resolved by 2012.

Recent history shows ongoing maintenance and enforcement issues primarily related to parking violations outside the property, with multiple citations issued for sidewalk parking and driveway blocking between 2021 and 2024. There is also an open concern from December 2021 regarding tree root damage to sidewalk/property. The building underwent extensive electrical work in 2006-2008, including installation of numerous electrical fixtures and systems. A lock-out incident was recorded with no civilian injuries. While many of the earlier building permits and compliance issues have been resolved, the property continues to experience periodic issues with parking enforcement and some exterior maintenance matters.

Risk rating

How 1359-1361 45Th Ave'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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
69th percentile

Out of 632 buildings in this neighborhood, 196 are predicted to be safer.

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.

Neighborhood location

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

Building size

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

Building age

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

12-Month severity forecast
No violation 42.1%
Moderate concern 17.5%
Severe concern 40.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
