Initial analysis

The Kong Family Trust owns this 2-story, 3-unit multi-family residential building located at 632-634 Masonic Ave in Park North. Built in 1912, the property has undergone several significant renovations, with the most substantial occurring in 2013 when ground floor improvements were made to legalize and add office, storage, play room, and bathroom facilities, including the installation of extensive electrical and plumbing systems (38 lights, 20 switches, 30 receptacles, 3 smoke detectors). The building's maintenance history shows attention to basic upkeep, including reroofing work completed in 2011 and wall tiling renovations in 2002.

The property has experienced several safety-related interventions, particularly concerning fire safety. In 2001 and 2017, the building faced fire violations that were subsequently resolved, including requirements for carbon monoxide alarms and fire extinguishers. A notable safety issue was documented in 2001 regarding a hazardous fire escape situation, though this was abated within weeks. The most recent building inspection occurred in 2017, with all cited violations being addressed promptly. Recent maintenance interactions have been minimal and primarily related to external factors, including three parking enforcement cases and one streetlight repair in 2020, as well as routine waste collection issues in late 2023. The building's history shows active management in addressing both routine maintenance and any safety concerns as they arise.

Risk rating

How 632-634 Masonic Ave'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
72th percentile

Out of 797 buildings in this neighborhood, 223 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.

Estimated permit spend (past 7 years)

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

Building age

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 72.4%
Moderate concern 21.0%
Severe concern 6.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
