Initial analysis

The property at 639-643 44th Avenue in San Francisco's Outer Richmond neighborhood is a four-story, multi-family residential building constructed in 1914, containing three units and currently owned by the Ahmed A Gaballah Living Trust. The building has undergone several significant renovations and repairs over the past three decades, with the most recent substantial updates occurring between 2017 and 2018, including interior remodeling of a bathroom unit with new finishes and mechanical systems, along with necessary electrical work. In 2017, the building underwent important structural maintenance including dry rot repair at the rear of the building and stucco replacement work, with corresponding electrical rewiring of three circuits related to heating systems. Historical records show earlier major work including roof reinforcement, bathroom remodeling, and deck structure improvements in 2007-2008, and foundation work in 1984.

The building has experienced some maintenance challenges as evidenced by recent complaints, particularly in 2020-2021 when concerns were raised about property blight, including reports of overgrowth, facade deterioration, and unauthorized use by skateboarders and homeless individuals. These complaints, filed through the city's 311 system, were eventually marked as not active, though specific resolution details are not provided. The property has a documented history of addressing required safety and maintenance issues, including past violations related to glazing and utility shutoff tools in 2003, which were resolved by May of that year. Recent 311 calls from 2023-2024 primarily relate to parking issues and general street concerns rather than building-specific problems, suggesting that while the property has faced maintenance challenges in the past, there have been no major building-related violations or complaints in recent years.

Risk rating

How 639-643 44Th 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

16th percentile

Out of 1040 buildings in this neighborhood, 874 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast

No violation 43.9%

Moderate concern 28.9%

Severe concern 27.2%

Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
