Initial analysis

The two-unit residential building at 1621 Waller Street, located in the Parnassus/Ashbury Heights neighborhood, is a two-story flats and duplex structure built in 1920, currently owned by John Rizzo and Christin Mills. The building's maintenance history includes several significant improvements, such as a complete reroofing in 1992, substantial interior renovations in 1991 involving the removal of bearing walls, kitchen remodeling, and new plumbing installation, along with a water heater replacement in 2016. Three notable maintenance permits from 1982, 1991, and 1992 are on record, though the specific nature of the 1982 permit is not detailed in the records.

The property and surrounding area have experienced numerous environmental challenges over the past year, particularly between October 2023 and September 2024, with multiple reports of garbage and debris, including instances of human waste or urine. Other reported incidents include two parking violations involving vehicles on the sidewalk (February and August 2024), a major event venue noise complaint (August 2024), graffiti on a bike rack (March 2024), and one encampment report that officers were unable to locate upon arrival (March 2024). These recent environmental issues, particularly the recurring reports of waste and debris, suggest ongoing challenges in the immediate neighborhood, though it's important to note that most of these incidents occurred on public property rather than within the building itself. The building's documented permits and improvements indicate regular maintenance attention to major systems and infrastructure over the past several decades, with no recorded complaints or violations directly related to the building's structure or systems.

Risk rating

How 1621 Waller St'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
74th percentile

Out of 526 buildings in this neighborhood, 137 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.

DBI complaint rate, owner's portfolio

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

12-Month severity forecast
No violation 70.3%
Moderate concern 18.2%
Severe concern 11.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
