Initial analysis

The property at 620-622 27th Avenue in San Francisco's Central Richmond neighborhood is a three-story, two-unit multi-family residential building constructed in 2014 following the removal of a previous structure. The substantial 2010-2013 construction project, valued at approximately $850,000, involved building a new duplex structure and included multiple safety and comfort enhancements such as the installation of a complete fire sprinkler system ($30,000), new plumbing infrastructure for six bathrooms, two kitchens, two laundry facilities, and modern electrical systems with 200-amp service. The building was equipped with sustainable features including a 3.1 kW solar rooftop system in 2019, though this permit has since expired.

The construction period generated some concerns from neighbors, with two complaints filed in 2012 and 2013 regarding potential permit violations, construction duration, and hazardous material handling - though these complaints were marked as not active. The property has experienced some ongoing infrastructure challenges as evidenced by recent 311 calls, particularly regarding pavement defects and a collapsed sidewalk reported in 2024, though the sidewalk issue remains open. The surrounding area has seen frequent parking-related incidents, with multiple reports of abandoned vehicles and driveway blocking between 2022 and 2024, though these are not directly related to the building's condition or management. The building's construction history shows careful attention to safety features and modern amenities, with most permits marked as complete, though some permits from 2013 may have relisted under different numbers without clear resolution status.

Risk rating

How 620-622 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
