Initial analysis

This two-unit residential building, located at 449 27th Street in Noe Valley, is a two-story flats and duplex structure built in 1913 and currently owned by the Janet M Gersonde Living Trust. The property's maintenance history shows attention to structural elements, with records of deck work in the mid-1980s and more recent street space and sidewalk repairs permitted in 2011. A significant safety incident occurred in 2023 with a carbon monoxide detector activation, though no CO was detected and no civilian injuries were reported.

The building has experienced frequent parking-related issues in recent years, particularly between late 2023 and 2025, with multiple reports of vehicles blocking driveways resulting in citations. There have been recurring abandoned vehicle reports in 2024, though in each case, the vehicles were gone upon officer arrival. The street's maintenance and public safety matters have been actively addressed by city services, with regular cleaning and various service requests being processed, particularly in early 2024. Of particular note is a tenant buyout at the adjacent address (461 27th Street) in August 2024, involving two tenants and a payment of $18,000, which may indicate recent changes in the neighborhood's rental landscape.

Risk rating

How 449 27Th 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
