Initial analysis

The two-unit residential building at 878-880 45th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1948 and currently owned by Mei Grant. Significant recent improvements include a substantial rear addition completed in 2014-2016 that added multiple bedrooms across two floors (initially 4 bedrooms planned, with a subsequent revision combining two ground floor bedrooms into one), along with comprehensive electrical work including the installation of 40 receptacles and 4 smoke detectors. The property has undergone several important maintenance and upgrade projects, including two solar installations in 2010 and 2011 (1.49 kW and 1.17 kW systems), furnace duct connections in 2016, and structural work in 2005 addressing dry rot issues and modifying the building's deck and overhangs.

The building's history also includes some concerning incidents that merit attention. In 1994, there was a housing inspection complaint regarding an illegal unit with uneven ceilings, potentially hazardous materials (foam with possible asbestos), and stained carpets, though this issue was marked as abated in 1995. More recently, in December 2016, there was a noise complaint filed during the construction period, specifically regarding construction activities and equipment use that allegedly disrupted the sleep of a night-shift worker, though this complaint is currently marked as not active. While the property has seen significant improvements and modernization efforts, including the installation of solar panels and safety features like smoke detectors, potential tenants should be aware of the building's historical issues with unauthorized unit modifications and past maintenance challenges that required attention.

Risk rating

How 878-880 45Th 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.
