Initial analysis

639 Shotwell Street is a three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by Gabriel W. Sulkes and constructed in 1900 as a three-story flats and duplex structure. The property underwent significant improvements in 2009-2010, including the installation of individual utilities for each unit (three bathrooms, kitchens, laundry facilities, and water heaters with radiant heat), electrical system upgrades with a new 400-amp service and complete rewiring, and final inspections for various building permits. A complete new fire sprinkler system was installed in 2000 at a cost of $10,000, though earlier attempts to install this system had been cancelled or expired.

The building has experienced recurring sewer-related issues, with multiple sewage back-up incidents reported in 2023-2024 from various sources including sewer vents and catch basins. Recent infrastructure concerns include open cases for pavement defects, tree root damage to sidewalks, and tree maintenance needs as of 2024. A notable planning proposal in 2023 to replace a rear one-story structure and add a second-level roof deck was ultimately disapproved due to concerns about encroaching into the required rear yard space. The property had a housing inspection complaint filed in 2010 that was notated as not active by 2012. Recent 311 calls have primarily focused on external environmental issues such as garbage and debris, though these were resolved by city services.

Risk rating

How 639 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
52th percentile

Out of 2380 buildings in this neighborhood, 1142 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.

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 63.9%
Moderate concern 25.2%
Severe concern 10.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
