Initial analysis

The three-story, two-unit residential building at 861-863 27th Avenue in the Central Richmond neighborhood was constructed in 2003, following the demolition of previous structures on the site. The property has undergone several maintenance and improvement projects since its completion, with the most recent being a significant siding replacement in September 2023 costing $33,612. Other notable upgrades include window replacements in 2012 and 2013, water heater replacements in March 2021, and initial electrical work including 150-amp service installation in 2003.

More recent developments raise some considerations about the property. A housing inspection complaint was filed in May 2024 regarding a potentially illegal unit (861A) on the ground floor, though this complaint is currently marked as not active. There have been multiple 311 calls in 2024 related to structural maintenance, particularly concerning recreation equipment and playground issues, though some of these have been resolved. The property has also been the subject of parking-related complaints, including sidewalk parking incidents. Historical records show a height complaint shortly after construction in 2003, though this was resolved within a few months. Three fire complaints were filed between 2009 and 2014, with two noted as having "No Merit" and one resolved with "Condition Corrected." The building's maintenance history includes regular updates to critical systems, such as the recent water heater replacements and siding maintenance, suggesting ongoing upkeep of the property.

Risk rating

How 861-863 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.
