Initial analysis

The two-unit residential building at 20-22 Appleton Avenue in Bernal Heights, owned by Carlye Anne Williams Greene, is a 1909 flats/duplex structure that has undergone significant improvements in recent years. Most notably, the property is in the process of converting from rentals to condominiums, with inspections and compliance work conducted throughout 2022, including electrical and plumbing updates. Recent major improvements include a comprehensive window replacement project in 2021 ($27,000) and simultaneous bathroom and kitchen remodels in 2019 on both units ($70,000 total). The building has seen substantial infrastructure upgrades, including the installation of a mini-split HVAC system in 2022, a new 200-amp electrical service in 2019, and a solar panel system added in 2016.

The property has experienced recurring sewer issues between 2019 and 2020, with multiple reports of sewage backups through a 4-inch vent, though these appear to have been resolved. Other maintenance work includes reroofing projects in 2012 and various renovation permits that have been properly closed out. The building's recent history shows regular upkeep and modernization efforts, particularly focusing on improving resident comfort and building systems. The only significant recent incident affecting resident experience was the sewer issues encountered in 2019-2020. The property has also experienced some parking enforcement matters, with three citations issued between 2019 and 2023 for vehicles blocking driveways, though these are not directly related to building conditions.

Risk rating

How 20-22 Appleton 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 1276 buildings in this neighborhood, 153 are predicted to be safer.
