Initial analysis

The three-unit multi-family residential building at 820-824 14th Street in Duboce Triangle is a three-story flats and duplex structure built in 1906, currently owned by Martin Z & Gail F Jacob 199. The building has undergone several significant maintenance and improvement projects over the years, including a reroofing project in 2005 costing $6,400, street space work in 2008, and a sewer line replacement in September 2008. A series of building violations were recorded in March 2005, including issues with stairs, handrails, and security requirements, all of which were abated by April 14, 2005. The property has undergone routine housing inspections in 1999, 2005, 2010, and most recently in 2019, with all cases being marked as not active.

Recent activity at the property has primarily involved parking-related issues, with multiple citations issued between August 2023 and October 2024 for illegal parking and driveway blocking. The building's current condition appears stable, with no active violations or complaints related to building safety or maintenance. The most recent routine inspection was conducted in December 2019, and the last documented building permit activity was in July 2017, both suggesting the property has been maintaining compliance with basic housing requirements. While there was one instance of graffiti on the public sidewalk in front of the property reported in July 2024, it was resolved after one month when no response was received from DPW BSES.

Risk rating

How 820-824 14Th 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.
