Initial analysis

The two-unit residential building at 538 27th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure owned by the Edmund K & Eva Wong 1990 Trust and was constructed in 1987 following the demolition of a single-family dwelling on the site in March 1986. The building's maintenance history includes a 1989 permit (now expired) for repairs addressing dry rot issues in the porch and rear stairs, along with window replacements, though earlier 1986 permits related to the property's initial construction and demolition are marked as complete.

The property has experienced recurring issues with parking violations in recent years, particularly between 2020-2024, with multiple documented cases of driveway blocking requiring police intervention and resulting in several citations. Of note, a parking citation was issued most recently in December 2023. The building's immediate surroundings have also faced some environmental challenges, including a damaged tree incident reported and resolved in July 2024. While the majority of 311 calls have revolved around parking enforcement, there was one instance of illegal postings reported in September 2020. The building's permit and planning records show no significant development activities or violations beyond the routine maintenance and repairs documented in the building permit history.

Risk rating

How 538 27Th 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

Out of 2250 buildings in this neighborhood, 428 are predicted to be safer.
