Initial analysis

The property at 523-525 41st Avenue in the Outer Richmond is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by Jacky Auyang. The most significant recent renovation occurred in 2010, when substantial improvements were made to the upper (second floor) unit, including kitchen and bathroom remodels, conversion of a half bath to a full bath, and window replacements, with associated plumbing and electrical work totaling approximately $38,000. This year also marked the official assignment of the additional address number 525 to the property. The building's maintenance history shows earlier attention to basic upkeep, with records of reroofing work from 1999 and bathroom floor repairs in 1985, though these permits have since expired.

Recent 311 calls related to the property primarily concern external issues, particularly recurring reports of sidewalk parking violations in the vicinity during 2022-2023. Other street-level incidents include a Christmas tree removal request in 2022, general cleaning needs in 2020, and reports of abandoned vehicles in 2019. The property area has experienced some infrastructure maintenance needs, with records of a collapsed sidewalk in 2016 and pavement defects in 2014, both of which were resolved through city intervention. A 2018 environmental health service request was transferred to the DPH Environmental Health - Healthy Housing & Vector Control Program, though the specific resolution details are not documented in the available data.

Risk rating

How 523-525 41St 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
49th percentile

Out of 1040 buildings in this neighborhood, 530 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.

Building age

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 69.4%
Moderate concern 23.9%
Severe concern 6.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
