Initial analysis

The two-unit residential building at 1728-1730 Waller Street in Haight Ashbury, owned by Sos 2008 Trust, is a two-story flats and duplex structure built in 1900. The property has undergone several significant renovations and faced various challenges over its history. In 2010, substantial improvements were made including interior renovations valued at $65,000 that added a bathroom, upgraded electrical systems, and new plumbing for another bathroom. Prior to that, between 2004-2005, the building underwent multiple renovations including a kitchen remodel, electrical upgrades, and some repairs to address dry rot in back stairs. A serious incident occurred in 1993 when the building suffered fire damage affecting floor joists and windows. The property experienced maintenance and compliance issues in 2004, including violations related to plumbing and sanitation that resulted from raw sewage problems, though these were abated by September 2004.

More recent history shows a period of vacancy in 2013-2014 that required attention to comply with the Vacant Building Ordinance. The building has maintained relative stability since then, though there have been ongoing maintenance and environmental challenges in recent years. Recent 311 calls from 2021-2024 indicate recurring issues with graffiti, sidewalk cleaning needs, and a missing side sewer vent cover from 2022. The most recent building-related 311 calls have been for abandoned furniture and graffiti, with the most recent issues being addressed in late 2024. While the property has faced various challenges over the years, the building appears to have received necessary repairs and upgrades, though recent calls suggest ongoing maintenance requirements in the surrounding area.

Risk rating

How 1728-1730 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
81th percentile

Out of 581 buildings in this neighborhood, 110 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.

Building age

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

Neighborhood location

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

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 76.7%
Moderate concern 13.7%
Severe concern 9.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
