Initial analysis

The two-unit residential building at 4073-4075 23rd Street in Noe Valley, owned by Mary Anne Mcguire-hickey, is a two-story flats/duplex structure built in 1900. The property has undergone several significant improvements over the years, with the most recent major work being a window replacement project in 2014 that installed new double-glazed windows throughout the building at a cost of $9,000. In 2014, there was also a proposed electrical upgrade including a new sub-panel and additional receptacles, though this permit was ultimately cancelled. Earlier improvements include a bathroom remodeling and window retrofit on the second floor in 2001, and substantial structural work in the early 1990s including a horizontal addition (1993), reroofing (1993), and replacement of the brick foundation with reinforced concrete (1992).

The property has experienced ongoing maintenance challenges related to its outdoor environment, particularly involving trees. Multiple reports between 2021 and 2024 document issues with overgrown and damaging trees, including problems with tree roots lifting the sidewalk. There have also been two sidewalk defects reported, one in 2022 that remains open and another in 2024 that was resolved. The building's exterior areas have experienced various other incidents requiring municipal attention, including illegal parking enforcement and occasional compliments to public works services. The tree maintenance issues, in particular, have been a recurring theme, with multiple reports of property damage and sidewalk impacts requiring municipal intervention.

Risk rating

How 4073-4075 23Rd 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
71th percentile

Out of 1879 buildings in this neighborhood, 545 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 permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 83.6%
Moderate concern 10.0%
Severe concern 6.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
