Initial analysis

The 6-unit, 3-story multi-family residential building at 543-545 Natoma Street in the South of Market neighborhood, owned by the Marilyn J De Vera Living Trust, has undergone several significant improvements and faced various maintenance challenges since its construction in 1908. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $80,000 to improve seismic safety. Recent building improvements include the installation of ground floor window security grilles in 2018 ($6,000), though some of these grilles were installed incorrectly into stucco rather than wood frames. The building has a documented history of maintenance issues, with a series of violations in 2004-2016 including problems with smoke alarms, carbon monoxide detectors, egress obstructions, weatherproofing, and various safety requirements, all of which were eventually abated by December 2016. Earlier complaints from 1995-1998 revealed concerns such as plumbing issues and security defects, though these were promptly addressed.

The property has experienced three recorded fire-related incidents, including an intentional fire and a false alarm, though fortunately none resulted in civilian injuries. Recent documentation shows attention to exterior maintenance, with work completed on roofing (2013) and various repairs to address weatherproofing and safety concerns (2012). The building's location has been affected by typical urban challenges, as evidenced by recent 311 calls in 2024 regarding sidewalk defects and various street maintenance issues, though these are external to the building itself. The most recent building inspection records indicate that the property is currently in compliance with most mandatory safety requirements, following the completion of significant retrofitting work and safety improvements in recent years.

Risk rating

How 543-545 Natoma 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 430 buildings in this neighborhood, 241 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 size

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

Number of units

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 36.5%
Moderate concern 43.1%
Severe concern 20.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
