Initial analysis

The two-unit residential building at 573-575 41st Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1987, currently owned by the Hamer Survivors Trust 1991. The building's maintenance record shows several significant upkeep activities, including a comprehensive reroofing project in 2002 costing $6,500, and more recently, bathroom renovations in 2021 involving tile replacements in both bathrooms with a cost of $3,000. The property was previously demolished in 1985 before the current structure was constructed.

The building's recent history has been marked by recurring parking-related issues, with multiple incidents of vehicles blocking driveways and parking on sidewalks between 2014 and 2024. Notable enforcement actions include citations issued in September 2022 for a Tesla blocking the driveway and an Acura SUV in 2018. The most recent parking complaint was filed in November 2024 regarding sidewalk parking, though the officer was unable to locate the vehicle. The property has also experienced occasional neighborhood maintenance issues, including reports of loose garbage requiring general cleaning in 2016 and 2019, and instances of illegal postings and graffiti on public property in 2014 and 2017, respectively. While these incidents don't directly impact the building's safety or resident experience, they do indicate some ongoing neighborhood maintenance challenges.

Risk rating

How 573-575 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
88th percentile

Out of 1040 buildings in this neighborhood, 125 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 81.8%
Moderate concern 10.9%
Severe concern 7.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
