Initial analysis

The two-story multi-family residential building at 139-145 Jasper Place in Telegraph Hill, owned by the Paul & Gail Caslavka Trust, was constructed in 1907 and contains 4 units. The property has undergone several significant renovations, most notably in 2002 when extensive structural work was completed including the removal of termite-damaged basement rooms, replacement of rotten beams with steel beams, and electrical upgrades costing approximately $45,590. More recent improvements include a $21,000 kitchen remodel in 2019 with electrical and plumbing upgrades, and a $12,000 reroofing project in 2020. There is currently an active complaint from June 2018 regarding unauthorized construction of a deck on the roof, and a historical violation was recorded in 2006 for a smoke door issue that was promptly addressed.

The building's maintenance history shows consistent upkeep, with multiple permit records for kitchen renovations in 2002, 2005, and 2019. Compliance issues have been relatively rare, with only one instance of plumbing work without a permit in 2002 and concerns about garage construction that were quickly resolved. Recent reports from 2021-2022 indicate multiple responses to general cleaning needs around the property and one sidewalk defect in 2022, all of which were resolved. A possible illegal short-term rental situation was reported and subsequently closed with a determination that the property currently features 30+ day renters. The property has maintained regular housing inspections with no major recurring violations, and while there were tenant buyouts recorded in 2021 at a nearby address (159 Jasper Place), there are no such records for this building location.

Risk rating

How 139-145 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
56th percentile

Out of 684 buildings in this neighborhood, 301 are predicted to be safer.
