Initial analysis

The two-unit building at 2475-2477 Vallejo Street in Pacific Heights is a two-story flats and duplex structure built in 1918, currently owned by Thomas W & Maggie K Chan 20. Since 2012, the property has undergone substantial renovations, including a comprehensive $150,000 remodel of two kitchens, four full bathrooms, and two half bathrooms, along with window replacements, electrical upgrades, and plumbing improvements. In 2010, the property had to address safety concerns when an illegal deck was removed, and security guard rails were installed to comply with building codes. The building experienced multiple fire safety system issues between 2017-2018, including violations related to sprinkler/standpipe systems and alarm systems, though all were eventually resolved. The property has had seven fire alarm incidents recorded, all determined to be false alarms or system malfunctions, with no civilian injuries reported.

Recent permits show maintenance work continuing through 2013, including window replacements, and the property has had various infrastructure improvements such as new heating systems and electrical upgrades. There was a proposal in 2007 to convert the two-family dwelling into a single-family home, but this application was withdrawn. The building's recent history shows no major safety violations or resident complaints, though there have been multiple parking enforcement issues in the surrounding area as evidenced by 311 calls throughout 2024. The property has undergone proper condominium conversion processes, with records showing both a withdrawn and an approved application for conversion.

Risk rating

How 2475-2477 Vallejo 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

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
80th percentile

Out of 963 buildings in this neighborhood, 193 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.

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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 81.0%
Moderate concern 13.3%
Severe concern 5.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
