Initial analysis

The three-unit, three-story multi-family residential building at 37-41 Jasper Place in Telegraph Hill, owned by Daniel Wong and Wai Soo Ho, has undergone several significant upgrades since its construction in 1911. Most notably, the building received a complete electrical system upgrade in 2014, installing 200-amp single-phase underground service with four meters and panels, including a house meter. Earlier improvements include new aluminum windows installed in 1987, reroofing work completed in 1995, and kitchen renovations in 1996. The building has undergone routine housing inspections in 1999, 2004, and 2007, with several violations recorded in 2004 and 2007 related to fire safety requirements, including fire extinguisher maintenance and combustible storage issues, as well as seismic bracing requirements for hot water heaters. All these violations were abated by August 2007.

The property has experienced recent environmental challenges, with multiple 311 calls in 2023-2024 regarding street cleaning, including reports of abandoned garbage, debris, and instances of human or animal waste. There was also a documented incident of graffiti on the building in February 2023, though this was noted to be related to a backlog of complaints resulting from COVID-19 enforcement suspensions. Older records show street space permits issued in 2007 and 2015, indicating some historical attention to public space management around the property. The building's maintenance history suggests regular upkeep and modernization efforts by the owners, particularly regarding safety systems and infrastructure, though the recent string of street cleaning issues indicates ongoing challenges in the immediate neighborhood environment.

Risk rating

How 37-41 Jasper Pl'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
