Initial analysis

The property at 1430-1432 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-story, multi-family residential building constructed in 1908, currently owned by Tang Ty. The building has undergone several significant infrastructure upgrades in recent years, including a furnace replacement in March 2023, multiple water heater replacements in March 2022, and an electrical system upgrade to 200-amp service in 2007. A notable building complaint was filed in July 2011 regarding a combination of issues including lack of heat, pest problems, mold, and a leaking ceiling, though these issues were marked as abated within two weeks.

The property's maintenance history shows regular updates to essential systems, though the presence of multiple gas water heaters suggests some redundancy or phased replacement approach. The most recent modifications include adding the second unit's address in 2013 and various window-related improvements dating back to the 1980s. In terms of external issues, there has been a notable pattern of parking violations near the property in recent months, with multiple reports of sidewalk parking and blocked driveways between 2023 and 2024, resulting in several citations being issued. While these parking issues don't directly affect the building's habitability, they represent a persistent neighborhood concern that is being actively monitored by city enforcement agencies.

Risk rating

How 1430-1432 48Th 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
47th percentile

Out of 632 buildings in this neighborhood, 335 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.

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 63.1%
Moderate concern 28.8%
Severe concern 8.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
