Initial analysis

The property at 1450-1452 47th Avenue in San Francisco's Outer Sunset neighborhood is a 2-story, 4-unit multi-family residential building constructed in 1909, currently owned by the Yee/Wong Family Trust. The building's permit history from 2006-2007 reveals several significant modifications, including the addition of a half bathroom and recreational room on the ground floor, foundation work, and compliance with a violation regarding the rear building's height. The property experienced multiple building complaints in 2007 related to unauthorized construction work, including claims of a vertical addition and raising the back structure approximately 2 feet without proper permits, though these issues were eventually resolved.

In recent years, the building has faced various maintenance and compliance issues, including a complaint in October 2023 regarding peeling paint affecting neighboring properties, and a fire complaint in February 2024 concerning blocked exits, which was corrected by April 2024. The property has also been the subject of multiple parking-related complaints between 2021-2024, though these are external to the building itself. Recent 311 calls indicate ongoing maintenance concerns, including clutter/hoarding issues and flooding incidents in the surrounding area in early 2024. The building underwent significant renovations in the mid-2000s, including kitchen and bathroom remodels in units 1450A and 1452A, electrical service upgrades, and various plumbing modifications, most of which were completed successfully despite some initial unauthorized work.

Risk rating

How 1450-1452 47Th 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
14th percentile

Out of 632 buildings in this neighborhood, 544 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.

Neighborhood location

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

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 31.2%
Moderate concern 33.8%
Severe concern 35.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
