Initial analysis

The 12-unit, three-story multi-family residential building at 3435 18th Street in the Inner Mission, owned by Litke Marghenta, was constructed in 1923 and has undergone several significant safety improvements over recent years. Most notably, the building completed its mandatory soft-story retrofit in 2017 (with subsequent revisions) at a cost of $82,000, demonstrating compliance with San Francisco's seismic safety requirements. The property has also recently updated its fire safety systems, with a fire alarm system upgrade completed in 2024 costing nearly $35,000, including the installation of low-frequency sounders in sleeping areas and a new fire alarm panel.

The building has experienced periodic safety and maintenance challenges, including a cluster of violations in September 2023 related to fire escape maintenance, gas shutoff requirements, and various compliance affidavits, though these were all abated by June 2024. There was also a significant complaint in June 2017 regarding construction debris during the seismic retrofit work, and a serious incident in 2008 involving scalding water affecting a tenant. The property has maintained an active history of regular updates, including boiler system improvements in 2023 and 2017, electrical service upgrades, and roofing work in 2004 and 1997. Recent inspections and work suggest ongoing attention to building safety, though the frequency of various complaints and violations over the years indicates typical urban building maintenance challenges. The building is categorized as a Tier 3 soft-story property, with its retrofit work completed and certified.

Risk rating

How 3435 18Th 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

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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 12.5%
Moderate concern 44.9%
Severe concern 42.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
