Initial analysis

The two-unit, two-story multi-family residential building at 650-652 Broderick Street in San Francisco's Park North neighborhood, owned by Mayes Kelly J & Johnson Knu, has a construction history spanning from 1907 to the present. Most recently, in 2023, the property underwent solar panel installation with two completed electrical permits showing the installation of a 4.68 kW system with 13 PV modules. There are current planning applications under review for constructing rear decks and stairs on the second and third floors, including access to the roof for solar panel maintenance, though these permits were initially submitted in January 2024 and subsequently cancelled.

The building has undergone several significant renovations and repairs over its lifetime, including a $19,500 reroofing project completed in 2020, and a substantial kitchen and bathroom renovation in both units in 2001, valued at $24,000. Historical records show attention to building maintenance following a notable incident in 2016 where a boiler issue caused flooding in the garage and downstairs area, which was addressed by the Plumbing Inspection Division. The property has had minimal external issues reported, with the most recent significant events being related to parking enforcement in 2021 when multiple vehicles were reported for blocking driveways, and the installation of security measures for a damaged ATT property in 2018. The building's age (built in 1907) and its completed modernization through solar panel installation indicate ongoing maintenance and upgrading by the current ownership.

Risk rating

How 650-652 Broderick 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
98th percentile

Out of 797 buildings in this neighborhood, 16 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.

Building age

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

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.

Property class: single-family home

Single-family homes (class A) have distinct violation and complaint patterns from multi-family buildings.

12-Month severity forecast
No violation 92.8%
Moderate concern 5.5%
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.
