Initial analysis

The 8-unit, 2-story multi-family residential building at 570 Duncan Street in Noe Valley, owned by Patrick W & Elaine M Shanah, has undergone several important upgrades and faced various maintenance issues since its construction in 1959. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $75,000, installing new cantilever columns and footings to improve seismic safety. Other significant improvements include the replacement of aluminum sliding doors in 2013, balcony decking repairs in 1993, and an electrical service upgrade with underground conversion in 2006.

The property experienced a cluster of building violations in September 2000, all of which were resolved by October 2000, including issues with fire safety equipment (fire extinguishers and smoke enclosure door closer), security features (main entry door locking devices), and gas utility requirements (shutoff tool and instructional diagrams). While there have been regular routine inspections, including one in 2010, recent records show primarily parking-related complaints, particularly regarding blocking driveways, with multiple citations issued between 2020 and 2024. There was also one noise complaint in 2021 and a general service request in November 2023. The building's maintenance history suggests active management, particularly regarding safety improvements, with no recent building violations or safety concerns apparent in the available records.

Risk rating

How 570 Duncan 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.

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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 43.3%
Moderate concern 26.7%
Severe concern 30.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
