Initial analysis

The two-unit residential building at 1410-1412 20th Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure owned by Lisa L Wing and built in 1951. The most significant recent improvement to the property occurred in late 2022, when comprehensive bathroom upgrades were completed, including the installation of new shower stalls, tiles, shower pans, valves, and drains on both floors, with associated plumbing work totaling approximately $30,000. This building also has a documented history of maintenance and upgrades, including a front stucco repair permit from 1999 and aluminum window installations from 1989, though these earlier permits have since expired.

In terms of recent municipal interactions, the building has experienced numerous parking-related incidents, with multiple reports of driveway blocking between September 2024 and January 2025, though many of these cases resulted in officers being unable to locate the offending vehicles. The most recent incident of note is an open request regarding a curb defect from December 2024. The frequency of parking enforcement calls suggests an ongoing challenge with street parking management in the vicinity, while the building's recent renovation work indicates active maintenance and upgrading of the property's facilities. The property appears to be maintained to code, as evidenced by the completion of all recent permits and the lack of any recorded safety violations or urgent repair needs.

Risk rating

How 1410-1412 20Th 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.
