Initial analysis

The property at 18-20 Shotwell Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1907 and currently owned by Munawar & Sofia Hussein, this building has undergone significant modernization and safety improvements over the past several years. The most substantial recent work includes the addition of a three-unit rear structure, completed in 2019-2021, which involved comprehensive infrastructure upgrades including a new fire sprinkler system, electrical wiring, and HVAC installations across all units (A, B, and C). Major safety improvements were implemented between 2019 and 2021, including the installation of dedicated fire sprinkler systems, seismic upgrades with moment steel frames and shear walls, and a fire sprinkler monitoring system with associated electrical work.

The building's plumbing and electrical systems have been extensively upgraded, featuring new drainage and venting systems, copper water lines, and a robust 400-amp electrical service with multiple subpanels and circuits to support modern amenities. While there were some earlier disturbances recorded in 2015-2016 (sidewalk parking, noise, and encampment issues), these were not building-specific problems and appear to have been resolved. The property underwent significant development oversight, including a variance approval process for the rear unit construction, demonstrating adherence to regulatory requirements. Recent maintenance and upgrade efforts suggest the building is actively managed, with most permits marked as complete, though a few earlier permits expired without finalization.

Risk rating

How 18-20 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

Out of 2380 buildings in this neighborhood, 976 are predicted to be safer.
