Initial analysis

The two-unit residential building at 3225-3227 20th Street in San Francisco's Inner Mission district is a 2-story flats and duplex structure built in 1900, currently owned by Yvette Lai-wah Macphee Revo. The building underwent significant improvements in 2016, including the replacement of the entry stairway, garage door, three street-facing windows, and the side entrance door, along with sewer repairs and minor electrical work, totaling $65,000. This renovation was accompanied by comprehensive plumbing upgrades including sewer lateral and street trap replacement and water service improvements. Electrical enhancements included new piping and wiring for exterior lighting.

The property has experienced persistent street-level concerns in 2023-2024, with multiple reports of loose garbage, hazardous materials, and general cleaning needs recorded through 311 calls. Recent incidents include mechanical equipment noise (open case as of September 2024), and various parking violations including sidewalk parking and driveway blockage. The building's permit history shows regular street space permits being issued between 2016-2018, suggesting ongoing attention to street-level maintenance. In addition to the completed renovation work, earlier attempts to address the exterior entry stairway, garage door, and windows in 2015 were withdrawn. The property has maintained compliance with safety and upgrade requirements, as evidenced by the completion of major infrastructure improvements, though the frequency of recent street cleaning and parking enforcement calls indicates ongoing neighborhood maintenance challenges.

Risk rating

How 3225-3227 20Th 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

Out of 2380 buildings in this neighborhood, 190 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.

Building permits, owner's portfolio

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

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 81.5%
Moderate concern 12.7%
Severe concern 5.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
