Initial analysis

The 9-unit, 3-story multi-family residential building at 1200 18th Avenue in the Inner Sunset, owned by Mark E & Sophia S Cusing Rv, was constructed in 1965 and has undergone several significant safety improvements over the years. Most notably, the building completed its mandatory soft-story retrofit in 2016 at a cost of $70,000, achieving Tier 3 compliance status. The property has received particular attention to fire safety, with a fire alarm system upgrade completed in 2023 to meet current standards, and multiple fire-related issues addressed over the years including problems with fire extinguishers, sprinkler systems, and alarm systems that were all corrected promptly.

The building has faced several safety and maintenance challenges, particularly evident in a series of active violations from July 2018 that include issues with structural maintenance requirements, rubbish removal, access for inspections, fire escape drop ladder operation, and carbon monoxide/smoke alarm requirements. A 2024 fire alarm system complaint and other maintenance concerns have been documented, though these were generally resolved promptly. Recent 311 calls (2023-2024) have primarily concerned external issues like sidewalk defects, garbage, and abandoned vehicles near the property. While the building has maintained basic safety compliance through various inspections and corrections, the presence of active violations from 2018 suggests some ongoing maintenance challenges. The property previously addressed violations from 2009 regarding fire escape ladders, fire extinguishers, and garage ventilation, demonstrating a history of responding to safety-related issues as they arise.

Risk rating

How 1200 18Th Ave'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
4th percentile

Out of 1493 buildings in this neighborhood, 1433 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 16.2%
Moderate concern 20.8%
Severe concern 62.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
