Initial analysis

The property at 312-314 Excelsior Ave is a two-unit, two-story mixed-use building constructed in 1915, currently owned by Rosales Fmly Tr. The building underwent a significant permitted renovation in 1998-1999 aimed at expanding the upper unit's living room and adding a half bathroom, though this work led to multiple building violations and a period of non-compliance that extended until August 2012. The building has required multiple permit renewals and experienced enforcement actions between 2000-2012 relating to the expired permit and lack of final inspections, although these violations were eventually resolved. More recently, the building received a new roof in 2018 at a cost of $9,100.

The property has experienced several parking and maintenance issues in the vicinity, with numerous complaints about vehicles blocking driveways and multiple reports of garbage and debris on the property between 2023-2024, though most of these issues were resolved promptly. There are two documented fire incidents: a contained cooking fire and a false alarm, with no civilian injuries reported in either case. The building's most recent planning record indicates a zoning verification letter of determination was issued, suggesting compliance with current zoning requirements.

Risk rating

How 312-314 Excelsior 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
36th percentile

Out of 337 buildings in this neighborhood, 216 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 age

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

Property class: apartment building

Severe concern 13.3%
