Initial analysis

The two-unit residential building at 1627 20th Avenue in San Francisco's Central Sunset neighborhood is a 2-story flats and duplex structure built in 1945, currently owned by the Geri Ortega Revocable Living Trust. The property's maintenance record shows several significant events, with the most recent being a completed electrical upgrade in January 2024 involving the installation of a 100-amp two-meter system with gutter and two main panels. In late 2022, there were some concerns regarding unauthorized construction work, with two complaints filed in August 2022 alleging unpermitted exterior work related to balcony removal and demolition. These complaints were filed shortly before and during the completion of permitted repairs to a dry-rotted decorative first-story balcony in November 2022, which was carried out according to approved plans to match Google 2022 photos at a cost of $1,500.

The building's recent history includes regular maintenance such as reroofing work completed in 1988, and the property has experienced some typical urban neighborhood issues as reflected in 311 calls, primarily regarding abandoned vehicle reports between 2018-2019, and a few street cleaning matters. Most of these 311 calls showed no merit or were resolved promptly, including a general cleaning request in July 2023 and a rent board customer callback in February 2022 that was successfully resolved. The proactive electrical system upgrade in early 2024 suggests ongoing investment in the building's infrastructure, though the period between 1988 and 2022 saw no major recorded permits or complaints, indicating relative stability in the building's maintenance history outside of the 2022 balcony issues.

Risk rating

How 1627 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.
