Initial analysis

The three-story, 18-unit apartment building at 3351 18th Street in San Francisco's Inner Mission district was built in 1908 and is currently owned by Wael & Betty Mufarreh Family. The building has undergone several significant structural and safety improvements over the years, including a mandatory soft-story retrofit completed in 2016-2022 at a cost of $89,000, and recent electrical upgrades in March 2023 for stairwell lighting. The building experienced multiple housing code violations in 2016 related to fire safety, sanitation, and structural maintenance, all of which were abated by March 2016. More recent issues include a sleeping area violation issued in October 2023, and a soft-story program violation in December 2022, though the work was later marked as complete with a CFC issued.

The property has a history of fire safety concerns, with several violations and complaints between 2006-2023 regarding alarm systems, blocked exits, and fire escape conditions. The building's maintenance history shows attention to critical infrastructure, with foundation repairs documented in 1999-2000 and various sidewalk and street space improvements. More recent complaints in 2022-2023 have focused on unit maintenance issues and common area inspections, including reports of damaged flooring and remodeling concerns. The building's location has been the subject of multiple 311 calls in 2024 regarding garbage, debris, and graffiti on or near the property, though these external issues don't directly impact building safety or habitability.

Risk rating

How 3351 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

Out of 2380 buildings in this neighborhood, 2332 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.

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 7.4%
Moderate concern 66.1%
Severe concern 26.4%
