Initial analysis

The three-story multi-family residential building at 148 9th Avenue, constructed in 1900, is a flats and duplex property currently owned by Wang Dan Yeung-foh & Scott-Wa, containing two units. The building's maintenance history shows two significant roofing projects: a completed reroofing in 1991 and a more recent one in 2011 costing $8,500, both of which suggest attention to structural maintenance.

The property has experienced several municipal service interactions over recent years, with the most recent occurring in late 2024 involving garbage and debris issues that were subsequently resolved. The early months of 2020 were particularly active for municipal service requests, including reports of various street cleaning needs, an overflowing city garbage can, and an overgrown tree requiring pruning— all of which were resolved. Some older service requests on record include a defaced parking sign in December 2020 and graffiti on another sign in January 2017, both of which were addressed by city services. A general service request made in May 2024 was documented as "Unable to Locate," though details on this matter are limited. The pattern of service requests suggests periodic challenges with street cleanliness and maintenance in the immediate vicinity, though all reported issues have been resolved through official channels.

Risk rating

How 148 9Th 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
