Initial analysis

The property at 485 Chenery Street is a 2-unit multi-family residential building located in Glen Park, built in 1900 and currently owned by Christopher M. Comparini. The most recent improvements to the building include a new heat pump and air handler installation completed in September 2023, along with electrical system upgrades including a new 30-amp circuit and service panel upgrade. This represents the latest phase of modernization efforts focusing on heating and electrical improvements. The building has undergone several significant renovations over the past decades, including a complete reroofing in 2015 (cost: $32,650), kitchen renovations on both floors in 2009-2010, and window replacements in 2009.

The property's history includes some notable concerns that have been addressed, particularly a cluster of violations in late 2000 related to basic services and maintenance issues, including heating, electrical systems, and interior surfaces, which were all abated by June 2001. There was also a mold complaint in 2003 and concerns about an unsafe building condition in 2008, though these issues were subsequently resolved. Recent planning records show a submitted application for additional remodeling work focusing on electrical system updates, insulation improvements, and better access to the backyard. While there have been multiple 311 calls regarding various issues near the property, such as street cleaning and abandoned vehicles, these are primarily external neighborhood matters and not directly related to the building's condition or management.

Risk rating

How 485 Chenery 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
92th percentile

Out of 364 buildings in this neighborhood, 29 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 84.5%
Moderate concern 11.1%
Severe concern 4.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
