Initial analysis

The two-unit, two-story multi-family residential building at 1463 20th Avenue in the Central Sunset neighborhood has undergone several significant improvements and faced some notable issues since its construction in 1946. Most recently, in August 2024, there was a completed project to replace four street-facing windows on the second and third floors with approved fiberglass materials, though this work generated at least one complaint about unpermitted remodeling and noisy construction. In September 2023, an electrical upgrade was completed with the installation of a 60-amp house meter and sub-panel, and in 2012, the gas line was repaired. The building has a documented history of parking-related concerns in the immediate vicinity, with multiple citations issued between 2022-2024 for vehicles blocking driveways and parking on sidewalks, though these issues pertain to street management rather than building conditions. Earlier building history shows a completed framing replacement in 1985 and an expired permit from 1986 for a proposed three-story addition, along with some 1992 building permit activity. The property has also maintained compliance with general maintenance requirements, as indicated by the resolution of various 311 calls related to street cleaning and illegal postings.

Risk rating

How 1463 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.

Neighborhood percentile
