Initial analysis

The property at 2550-2552 Folsom Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1880 and currently owned by Daniel E Rangel Jr. The building has undergone several significant renovations and maintenance projects over the past decades, with the most substantial work occurring between 2016-2018. This major renovation phase included a comprehensive remodel of kitchen and bathroom spaces, replacement of aluminum windows, insulation and sheetrock work, and reinforcement of chimney elements, with permits showing costs ranging from $55,000 to $80,000. During this period, there was also a permitted demolition of a rear shed/storage structure, and the addition of a dropped ceiling and relocation of bathroom fixtures.

The building's utilities received an upgrade in 2004 with the conversion of overhead service to underground power. In terms of recent activity, there have been multiple parking enforcement issues recorded between 2022-2024, with several citations issued for driveway blocking violations. The property has also experienced recurring issues with graffiti, particularly affecting nearby fire hydrants, though these have been resolved by city services. The most recent building-related activities have primarily involved routine maintenance and external clean-up matters, with no documented safety or structural concerns. The property's permit and maintenance history suggests regular upkeep and upgrading of facilities, with no significant negative events recorded that would impact resident safety or comfort.

Risk rating

How 2550-2552 Folsom St'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.
