Initial analysis

The three-story, six-unit multi-family residential building at 49-51 Walter Street in Duboce Triangle, owned by Eric Phillip Xanthopoulos and constructed in 1907, has undergone several significant modifications and faced various compliance challenges in recent years. Most notably, the building is currently classified as non-compliant with the city's soft-story retrofit program (as of 2022) despite permit applications in 2018 and 2019 for structural work valued at $35,000 and $77,000 respectively. There is also an active complaint from February 2023 regarding common area conditions. The property previously attempted to address its soft-story requirements through permits filed in 2018 and subsequent revisions in 2019, demonstrating ongoing efforts to comply with safety mandates.

Additional recent improvements include plumbing work completed in December 2019 involving gas line repairs and valve replacements. The building's history includes notable violations from 2002 related to fire safety, security, and general maintenance issues, though these were all abated by October 29, 2002. There was also a significant complaint about various maintenance issues including roof leaks, water intrusion, inadequate lighting, pest problems, and fire safety concerns from February 2002, and a plumbing violation regarding unauthorized work from 2004. The property has experienced multiple street-level service calls in recent years, primarily related to general cleaning and waste management, with the most recent being encampment-related in February 2024. A neighborhood concern regarding short-term rental activity was investigated and marked as closed in 2018. While there have been two fire-related complaints (in 2008 and 2019), both were determined to have no merit. The building's most recent permitted work includes the addition of an ADU (Accessory Dwelling Unit) at the ground floor, approved under Ordinance 162-16, which aimed to increase the unit count to seven.

Risk rating

How 49-51 Walter 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

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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Number of units

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

Building size

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

12-Month severity forecast
No violation 36.9%
Moderate concern 39.3%
Severe concern 23.8%
