Initial analysis

The three-story, two-unit residential building at 239-241 Valley Street in Noe Valley, constructed in 2004, has undergone extensive modifications and faced several notable issues over its history. The property underwent significant renovation in 2008 when an additional unit was added to the garage area, along with various deck constructions and interior modifications, though this work triggered multiple permit revisions in subsequent years due to changes in scope and structural requirements. Between 2012-2013, substantial infrastructure improvements were made, including roof replacement, plumbing and electrical upgrades, and the addition of modern amenities such as a fireplace and new HVAC systems. Several safety concerns were documented between 2012-2014, including unauthorized roof modifications, construction-related debris issues, and a lack of handrails on new stairs, though these complaints were subsequently addressed. A cluster of complaints in 2016 regarding unpermitted sewer line work and plumbing issues was quickly resolved within a week of reporting.

More recently, the property has experienced ongoing issues with parking and driveway access, as evidenced by multiple citations and complaints between 2022-2024, indicating a persistent challenge with neighboring vehicle congestion. A significant infrastructure concern was reported in February 2023 regarding a collapsed sidewalk, which remains open as of the latest records. The building's maintenance records show regular upkeep of essential systems, including a recent skylight installation in 2021 and various permit renewals to ensure compliance with current codes. The property has maintained its classification as a multi-family residential building throughout its history, with ownership currently held by Allison Isaacs Trust.

Risk rating

How 239-241 Valley 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
93th percentile

Out of 1879 buildings in this neighborhood, 132 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 location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

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 89.8%
Moderate concern 8.1%
Severe concern 2.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
