Initial analysis

The property at 531-533 2nd Avenue is a two-story, multi-family residential building located in the Inner Richmond neighborhood, owned by Loo Marital Trust and containing three units. Built in 1905, the building has undergone several significant renovations, with the most substantial occurring in 2013 when major upgrades were made to the kitchens and bathrooms in multiple units, including the addition of a new address for unit 531A, with work properly permitted across plumbing, electrical, and building departments. Earlier infrastructure improvements included an electrical service upgrade and installation of two meters in 2004, suggesting modernization efforts to improve the building's utility systems.

The building has a documented history of regular safety inspections, with the most recent routine safety inspection recorded in December 2015. While there have been three notable complaints regarding building safety in 2004 and 2013, all were resolved, including a 2004 inspection that raised issues about emergency exits, smoke detectors, and wood stairs, which were all abated by March 2005. The property has maintained active compliance with building codes since then, though there have been several recent 311 calls related to parking issues, including multiple instances of blocked driveways and sidewalk parking between 2022 and 2024. There is currently one open issue from August 2024 regarding a dead tree on the property that requires attention.

Risk rating

How 531-533 2Nd 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
46th percentile

Out of 1723 buildings in this neighborhood, 930 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.

Estimated permit spend (past 7 years)

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

Building age

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 78.5%
Moderate concern 16.6%
Severe concern 4.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
