Initial analysis

The property at 1528-1532 Grant Avenue is a three-unit multi-family residential building located in Telegraph Hill, owned by Tony L Wong Revocable Trust and constructed in 1904 as a three-story flats and duplex structure. The building has undergone several significant maintenance and repair projects over the past few decades, with notable work including window and door replacements and roofing work completed in 2003 ($7,700), water main replacement in 2007, and various plumbing upgrades to meet accessibility standards in 1998. Of particular concern are multiple historical violations and complaints, including a 2003 issue regarding unauthorized roof deck and structure modifications, a 2000 incident involving interior damage and multiple housing code violations across various categories (including fire safety and interior surfaces), and a 2007 complaint about broken water service.

Recent history shows fewer maintenance issues, though there was a significant complaint in 2017 regarding unauthorized rooftop structures and deck modifications that exceeded height limits. The building experienced some exterior maintenance issues in recent years, including a 2022 graffiti incident and various cleaning matters along the street front as documented in 311 calls. Most of the historical building violations have been marked as resolved, with many dating back to 2000-2004 being addressed through various completed permits and corrections. The property has undergone regular maintenance over the years, including multiple street space uses with MTA permits, though there were some cancelled or expired permits in earlier years that may indicate incomplete or postponed work.

Risk rating

How 1528-1532 Grant 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

Out of 684 buildings in this neighborhood, 315 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.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 64.9%
Moderate concern 18.3%
Severe concern 16.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
