Initial analysis

The two-story, four-unit multi-family residential building at 1133 Webster Street in the Western Addition neighborhood, owned by Joseph P Grubb 1993 Revocable Trust, has a documented history spanning several decades since its 1926 construction. Significant maintenance and safety events include a complete re-roofing in 2016($8,500), fire safety improvements in 2008 addressing multiple violations including fire proofing repairs ($600), and a 2007 kitchen and bathroom remodel ($18,000) that included electrical upgrades. The building experienced notable issues in March-April 2008 when it faced multiple violations related to water damage, drainage pipes, fire proofing, and garage ventilation, though these were all resolved by April 23, 2008. Earlier maintenance included electrical service upgrades in 1988 and termite damage repairs in 1995.

Most recent maintenance activity includes plumbing work in 2019 for water heater installation and street space usage permit in 2019. The building has undergone routine safety inspections in 2010 and 2018, with all identified issues being resolved. Recent 311 calls from 2022-2024 primarily relate to street cleaning and parking enforcement outside the building, with the most concerning recent issue being a "lifted sidewalk" report from November 2024, which remains open. While there was one recorded building fire incident (type 111, unintentional, with no civilian injuries), there have been no other major safety incidents reported in recent years. The property has maintained compliance with housing codes since 2008, with no active violations on record.

Risk rating

How 1133 Webster 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
57th percentile

Out of 167 buildings in this neighborhood, 72 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

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

Building age

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

12-Month severity forecast
No violation 58.1%
Moderate concern 27.0%
Severe concern 14.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
