Initial analysis

The three-unit, three-story multi-family residential building at 42-44 Jasper Place in Telegraph Hill, owned by Ronan Hanley, has undergone several significant improvements and renovations since its construction in 1900. Most recently, in October 2023, revisions were made to adjust walls in various areas including the utility room, front bedroom/bath, and rear media and office rooms. This follows a major 2020 renovation that introduced an ADU in the basement level with comprehensive plumbing and electrical work, valued at $192,000. In 2019, the building received substantial updates including the replacement of non-historic windows on the front facade with new all-wood windows, restoration of the center mullion, and a comprehensive interior renovation across all three units featuring new kitchen cabinets, countertops, flooring, trim, and bathroom improvements totaling $66,149.

The building has a history of addressing safety and maintenance concerns, with two routine housing inspections conducted in 2004 and 2007 that identified various issues including fire alarm system repairs, security requirements, and seismic bracing for the hot water heater. These violations were all promptly abated, with the final resolution occurring on October 20, 2004. The property underwent re-roofing in 2005, and while there have been numerous 311 calls in recent years (particularly in 2024) regarding garbage and debris, these appear to be related to street cleaning issues rather than building-specific problems. The building's maintenance record shows regular attention to both interior and exterior improvements, particularly focusing on preserving and upgrading historic elements such as windows and facade features.

Risk rating

How 42-44 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

Out of 684 buildings in this neighborhood, 192 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 79.4%
Moderate concern 14.5%
Severe concern 6.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
