Initial analysis

The two-story multi-family residential building at 151 28th Street in Noe Valley, owned by Ormon M & May Y Yee Tr-surv, was constructed in 1951 and contains four units. The property has undergone several significant improvements over the years, with the most recent major work being a substantial kitchen remodel in Unit 3 completed in 2024, costing $40,000, including new cabinets, countertops, plumbing, and electrical work. Previously, in 2017, a $20,000 renovation was completed which included kitchen and bathroom updates with new cabinets and tiles. The building's electrical infrastructure received significant upgrades, including a 400-amp service installation in 2020 and a 200-amp service upgrade in 2017, indicating attention to modernizing the building's systems.

The property has maintained compliance with safety regulations, with only one set of violations recorded in October 2008 during a routine inspection, concerning fire extinguisher maintenance and water heater seismic bracing, both of which were promptly abated by November 19, 2008. The building's maintenance history shows regular upkeep, including a roofing project completed in 2016 at a cost of $22,800. Recent activity in the surrounding area (2023-2024) has primarily involved parking-related issues, with several complaints about blocked driveways and abandoned vehicles, though these are external to the building itself. Historical records also show a construction plate issue in 2013, which was resolved through proper channels. The building's permit and violation history suggests a proactive approach to maintenance and compliance with building codes, with no active violations or complaints in recent years.

Risk rating

How 151 28Th 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.

Model explanation

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.

12-Month severity forecast
No violation 56.3%
Moderate concern 24.0%
Severe concern 19.7%
