Initial analysis

The properties at 636-638 Hampshire Street are two-story, multi-family residential buildings located in San Francisco's Inner Mission neighborhood, owned by the Anderson Family Trust and constructed in 1900. The building has undergone several significant infrastructure improvements over the past two decades, including a 100-ampere electrical service upgrade with three meters completed in 2004, complete sewer and house trap replacement (approximately 65 feet) in 2022, and window replacements in 2011 where five street-facing windows were upgraded to energy-efficient fiberglass framed units with a maximum U-factor of 0.40. An earlier roofing project from 1997 is listed as expired in the permit records.

The building's recent history shows no fire incidents or civilian injuries on record, indicating a good safety track record in that regard. However, there have been multiple parking-related issues in the vicinity, with several citations issued for illegal parking and sidewalk blocking between 2020 and 2024. The area has experienced some public space maintenance challenges, as evidenced by 311 calls regarding street cleaning needs, including reports of loose garbage and waste. The most recent inspection by the Department of Public Health occurred in October 2023, though the specific nature of this interaction is not detailed in the records. The building's infrastructure improvements over time suggest regular maintenance and upgrading of essential systems, though some parking enforcement and street cleaning issues in the surrounding area may affect resident experience.

Risk rating

How 636-638 Hampshire 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
85th percentile

Out of 2380 buildings in this neighborhood, 357 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.

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 75.7%
Moderate concern 18.8%
Severe concern 5.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
