AI summary

The Kornfeld-blankenship Revocable Trust owns this two-story, four-unit multi-family residential building located at 436-438 Masonic Ave in Park North, originally constructed in 1900. The property has undergone several significant renovations and maintenance projects over the years, with the most recent being a completed reroofing project in July 2024 costing $13,000 and a house trap replacement in July 2022. Notable improvements were made in 2008 when substantial renovations were completed on multiple units, including kitchen remodels, electrical upgrades, and bathroom improvements, with a documented sewer repair from the curb to the building also completed that year.

The building has experienced some maintenance issues over time, including a 2018 incident involving improper water heater venting that required corrections, and a January 2011 complaint about mold and deck maintenance that was subsequently addressed. Several fire safety complaints were recorded in 2014 and 2018, all of which were resolved with conditions corrected. Recent exterior maintenance concerns have included reports of sidewalk defects (August 2023), though most recent complaints primarily relate to parking violations and toters management. The property's maintenance history shows regular upkeep, with recent improvements focusing on infrastructure maintenance such as roofing and heating system updates, suggesting ongoing maintenance attention by the current ownership.

Risk rating

How 436-438 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
36th percentile

Out of 797 buildings in this neighborhood, 510 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 58.7%
Moderate concern 17.5%
Severe concern 23.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
