Initial analysis

The two-unit residential building at 513 Webster Street in Alamo Square, owned by Wilson Devon & Ravenscroft, has a complex history dating back to its 1900 construction. The property underwent significant improvements in 2017, including exterior repairs, window replacements, and facade painting, totaling approximately $20,000. During this period, the owners also clarified the building's unit count. In 2021, a new heat pump was installed for climate control, though this followed a complain about inadequate heating from April 2021 that was resolved by November 2021.

The building has faced multiple challenges throughout its recent history, with a notable cluster of violations and complaints in 2010-2018 that included general dilapidation, security bar concerns, handrail issues, and fire safety violations. These violations, documented in 2010, were not fully abated until January 2018, during which time multiple citations were issued and a director hearing was held in September 2011. More recent maintenance work includes flashing installation to the garage roof (2017) and various repairs to address dry rot issues in the garage (2014), with earlier maintenance history showing efforts to address lead paint concerns. The building's systems received attention in 2021 with the heat pump installation, addressing a significant tenant complaint. Recent 311 calls from 2023-2025 have primarily concerned street-level issues such as illegal postings, garbage, and graffiti, rather than building-specific concerns, suggesting improved building maintenance and fewer internal issues. The property's documented history shows a progression from significant maintenance challenges to more routine upkeep in recent years, with major violations having been resolved and building systems receiving regular updates.

Risk rating

How 513 Webster 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
51th percentile

Out of 305 buildings in this neighborhood, 149 are predicted to be safer.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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