AI summary

The three-unit multi-family residential building at 737-741 Webster Street, owned by Heskes Family-a LLC, was constructed in 1900 and has experienced several significant maintenance and safety incidents throughout its history. Most recently, in March 2023, the building underwent a substantial reroofing project costing $26,650, which was properly permitted. Between late 2022 and early 2023, the building faced serious heating system issues, including multiple complaints about inadequate heat and gas safety concerns, with residents reporting non-functional wall heaters and an improperly connected gas fireplace. These heating problems resulted in violations that were not abated until February 2023, after PG&E issued replacement instructions in May 2022.

The building's history shows a pattern of maintenance challenges, particularly around 2012-2013, when there were multiple issues including unauthorized bathroom remodeling, mold problems, and water damage affecting multiple units. During this period, several permits were issued to address various improvements, including plumbing work for a laundry room conversion and bathroom repairs. More recent improvements include a complete electrical service upgrade in 2021 with new meter sockets and circuit breaker panels for the three units, demonstrating investment in building infrastructure. The property has undergone regular inspections over the years, with a 2018 routine safety inspection and a 2008 health and safety inspection being noted in the records. While there have been several 311 calls related to the property in recent years (2020-2024), these have primarily concerned external issues such as sidewalk conditions and street cleaning rather than internal building maintenance problems.

Risk rating

How 737-741 Webster 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
73th percentile

Out of 305 buildings in this neighborhood, 82 are predicted to be safer.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age
