Initial analysis

The three-unit, three-story multi-family residential building at 326-328 Guerrero Street, owned by Jiang Sirui, was constructed in 1910 and has undergone several significant renovations and improvements over the past decade. Most notably, in 2015-2016, the property underwent substantial remodels including a complete bathroom renovation, kitchen updates, electrical system upgrades (adding 10 circuits, 6 lights, and 20 receptacles), and furnace replacements in response to previous heating system violations. The building experienced multiple building violations in 2003-2004 related to stairs, handrails, heating systems, and interior surfaces, all of which were officially abated by 2004. A concerning tenant complaint from 2004 described unhealthy living conditions with crumbling concrete and pest issues, though this was resolved by 2009.

More recent upgrades include a 2015 reroofing project costing $7,200. The building has a history of maintenance issues that have generally been addressed, including heating system problems noted in a 2012 complaint about electrical outages when heaters were used. The property has received regular attention to both building and safety standards. Recent 311 calls from 2020-2024 primarily relate to external issues such as noise, graffiti, and street cleaning, rather than internal building concerns. These external matters were generally resolved or closed promptly, indicating ongoing attention to property maintenance.

Risk rating

How 326-328 Guerrero 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.
