Initial analysis

The property at 43 Downey Street is a two-unit, two-story multi-family residential building located in San Francisco's Haight-Ashbury neighborhood, owned by David W. Port and Margo. Built in 1900, this flats and duplex structure has undergone several significant renovations and faced multiple compliance issues over its history. The most recent substantial work includes a kitchen remodel completed in 2022 ($30,000) and the installation of two new water heaters in late 2022. A notable compliance issue was resolved in 2020 when the demising wall between units was reinstated in accordance with planning department requirements, following a history of unauthorized interior modifications.

The building has undergone extensive improvements since 2009, including a complete electrical system upgrade with new service, sub-panels, and rewiring of all rooms, along with plumbing improvements such as new water lines, heaters, and kitchen drains. Historical records indicate past safety concerns, particularly regarding stair and entryway conditions in 2005-2006, which resulted in multiple Notices of Violation. These issues were ultimately addressed through comprehensive repairs to front entry, stairway, and landing areas, along with kitchen and bathroom remodels in both units. The property has also experienced recurring driveway blocking issues, with numerous citations issued between 2023 and 2024, suggesting ongoing challenges with parking management in the vicinity. A planning investigation in 2010 revealed unauthorized modifications attempting to create an interior connection between units, though the building's use remained officially registered as two separate units with individual kitchens.

Risk rating

How 43 Downey 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 581 buildings in this neighborhood, 12 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.

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 88.8%
Moderate concern 9.2%
Severe concern 2.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
