Initial analysis

The two-unit residential building at 48-50 Shotwell Street, located in San Francisco's Inner Mission neighborhood, is a two-story flats and duplex structure built in 1907 and currently owned by David T. Pang. The building's permit history shows several maintenance activities, including a 2008 fence replacement project at the northwest rear corner, completed at a cost of $500, and an expired roofing permit from 1991. Two notable building complaints are on record: one from 2009 regarding the construction of an unauthorized room in the garage (which was not abated until 2010), and another from 2008 concerning improper soil disposal during backyard work that affected neighboring property, though this issue was resolved the same day it was reported.

The most recent and significant pattern affecting the property and its surroundings is a series of waste management and public safety issues documented in 2024, with multiple reports of garbage and debris (including furniture) on or near the property between August and October 2024, all of which were resolved through cleanup efforts by various city services. There were also two encampment-related incidents reported near the property in October 2024, though both cases were either unable to be located or transferred to a different department for handling. The building's historical and recent permit and complaint records suggest an ongoing need for vigilance regarding property maintenance and neighborhood conditions, while also showing some past challenges with unauthorized modifications and construction practices, though most historical issues appear to have been resolved.

Risk rating

How 48-50 Shotwell 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.

Neighborhood percentile
