Initial analysis

The property at 1450-1452 9th Avenue in San Francisco's Inner Sunset is a two-unit, two-story multi-family residential building constructed in 1914, currently owned by Jack H. and Denise Hendrickson. The building's maintenance history shows regular upkeep, with the most recent significant improvement being the installation of a new roofing system in 2022, replacing the old flat roof with a new torch-on system at a cost of $11,000. The owners have also filed permits to add an ADU unit as part of the state program in October 2022, though this application is still in "Filed" status. The building underwent electrical system modernization in 2003 with the completion of an underground service conversion and installation of a new 200-amp house meter with 15 circuits.

The property has experienced several quality-of-life issues over the past few years, particularly regarding parking enforcement, with multiple complaints about driveway blocking between 2018 and 2023, often involving the same vehicle (a Mercedes with different plates). There was also one noise complaint in 2020 and a graffiti incident reported in 2016, though these cases were either invalid or transferred to PG&E. The building's maintenance record shows attention to structural issues, including previous work in 1989 on the front building's stucco and an expired roofing permit from 1996, though these are much older compared to recent improvements.

Risk rating

How 1450-1452 9Th 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
98th percentile

Out of 1493 buildings in this neighborhood, 30 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.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

Building age

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

12-Month severity forecast
No violation 93.0%
Moderate concern 5.3%
Severe concern 1.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
