Initial analysis

The multi-family residential building at 150-152 Onondaga Avenue in Mission Terrace is a 2-story, 2-unit structure built in 1915 owned by Noel & Cristina Masangcay. The property has had several significant issues over the years, most notably in 2003-2005 when multiple complaints were filed regarding illegal units, including a converted garage space into living quarters and laundry facilities, which were ultimately removed at a cost of $6,500. These violations were part of a larger pattern of unauthorized modifications, though more recent records show no active violations or complaints regarding illegal units. The building underwent various improvements with building permits in 2007, including a kitchen remodel, furnace and water heater updates, and electrical work totaling $14,000, along with gas houseline extensions in 2013 and solar panel installation in 2016 (4.48 kW system). The property has experienced multiple maintenance issues, including reports of plumbing work without permits (active complaints from 1999), twice-reported open walls with plumbing and electrical remodeling (1999), and past housing concerns such as lack of heat and water intrusion (1997).

Recent activity at the property has primarily consisted of routine street maintenance issues and parking concerns rather than building-specific problems. Between October 2024 and December 2024, there were several 311 calls regarding garbage and debris, illegal parking, and one sewage back-up discharge from a side sewer vent. A Rent Board request related to fee and housing inventory was filed in early November 2024. Planning records indicate historical concerns about unauthorized units and garbage accumulation, though these issues were marked as closed and abated. The building's most recent significant improvement was the installation of a 4.48 kW solar panel system in 2016, suggesting some commitment to energy efficiency upgrades.

Risk rating

How 150-152 Onondaga 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
81th percentile

Out of 149 buildings in this neighborhood, 28 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 65.9%
Moderate concern 19.9%
Severe concern 14.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
