Initial analysis

The 5-unit, 2-story apartment building at 4141 Noriega Street in San Francisco's Outer Sunset neighborhood, owned by Vrej & Maida Mekhalian Rev, has experienced several notable maintenance issues since its 1957 construction. Most recently, in early 2022, the building suffered water intrusion problems that required the replacement of damaged windows, affecting tenant-occupied apartments. This followed a documented history of moisture-related issues, including a December 2022 complaint detailing water intrusion into a second-floor unit with leaking ceilings and window problems first reported in October 2021. The building underwent electrical system upgrades in 2010 with the replacement of deteriorated service equipment, and faced multiple violations in late 2022, including issues with electrical fans, fire safety equipment, and waterproofing, though these were abated by January 2024.

Earlier maintenance history includes various repairs and improvements, such as termite and dry rot repairs in 1996, wood siding replacement with stucco in 2006, and window replacements in 2003. The building has experienced recurring moisture-related problems, with documented mold issues in 2006 and 2012. Recent building permit activity includes the replacement of two street-facing windows in 2022 as part of ongoing maintenance. While the building has had various maintenance and compliance issues over the years, including fire safety and electrical problems, the most recent violations have been addressed and abated, suggesting active management of building maintenance requirements.

Risk rating

How 4141 Noriega 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
6th percentile

Out of 632 buildings in this neighborhood, 594 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.

NOV rate, owner's portfolio

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

Number of units

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

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 22.8%
Moderate concern 29.5%
Severe concern 47.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
