Initial analysis

The property at 640-642 Shotwell Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by Michael P Manzo and constructed in 1900. The building has undergone significant improvements in recent years, with completed bathroom remodels in both units (2021 at 642 and 2022 at 640) including modern fixtures, water and vent pipe updates, and lighting improvements, at costs of approximately $10,561 to $14,500 per unit. Substantial infrastructure upgrades have been completed in 2023, including a furnace and heat pump replacement with new electrical service (upgraded from 100 to 200 amps), demonstrating investment in building systems. Previous improvements include a complete rewiring of the top floor unit (2019) and a tankless water heater replacement with gas line upgrades (2020).

The property has experienced multiple fire alarm activations, primarily due to smoke detector malfunctions or false alarms, though none resulted in fires or civilian injuries. There have been no significant safety incidents reported. While there have been several 311 calls regarding garbage, debris, and illegal parking in the vicinity during 2024-2025, these are external issues and not directly related to building conditions. Notably, there was a significant proposed expansion project in 2009 to add two stories and a lateral addition, though this permit was ultimately cancelled. The building's permitted work history suggests ongoing maintenance and improvement efforts, with particular focus on modernizing bathrooms, updating HVAC systems, and maintaining electrical infrastructure.

Risk rating

How 640-642 Shotwell 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, 1428 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 64.2%
Moderate concern 28.3%
Severe concern 7.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
