Initial analysis

This two-story, six-unit multi-family residential building in Noe Valley was constructed in 1905 and is owned by Theodore M. Scalione Jr. The property has undergone several significant improvements in recent years, most notably a complete soft-story retrofit completed in 2017 at a cost of $75,000, bringing the building into compliance with seismic safety requirements. The building has received consistent maintenance and upgrades over the past two decades, including multiple kitchen and bathroom remodels (2010, 2013, 2014), window replacements (2014), and a complete reroofing in 2006. Several permits for street space usage have been issued, with the most recent one in October 2017.

The building experienced some challenges related to lead paint hazards in 2006, when multiple violations were recorded regarding damaged paint and fire safety concerns, though all were abated by June 22, 2006. There have been recurring issues with paint removal procedures, with complaints filed in 2010, 2013, and 2014 regarding improper containment of paint debris, though these were all resolved. A planning application from 2006 for constructing an additional two-unit building on the same lot was withdrawn. The property has maintained a clean safety record, with no fire incidents resulting in civilian injuries on record, and it is classified as a Tier 3 soft-story building with completed retrofit work and a Certificate of Final Completion issued. Recent 311 calls from 2023-2024 primarily relate to street cleaning and graffiti removal, which are municipal maintenance issues rather than building-specific concerns.

Risk rating

How 3800-3818 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

Out of 1879 buildings in this neighborhood, 1466 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 44.0%
Moderate concern 28.4%
Severe concern 27.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
