Initial analysis

The 6-unit, 2-story multi-family residential building at 336 Valley St in Noe Valley, owned by Jonathan Mayeda, was constructed in 1963 and has undergone several significant renovations. The most substantial work occurred in 2008-2009, including a major facade renovation that involved window replacement, lightwell roof work, skylight installation, siding replacement, and updates to the west exterior wall with fire-rated materials and insulation. This phase also included plumbing improvements such as catch basins and roof drains. In 2017, the building received additional maintenance with the replacement of approximately 400 square feet of rear siding. A routine housing inspection in October 2008 was conducted and resolved on the same day.

More recent history shows various parking enforcement issues near the property, particularly concerning driveway blockages, with multiple citations issued between 2018 and 2024. The most recent incident occurred in March 2024, and similar complaints were resolved through enforcement actions in February 2022 and November 2023. A fire alarm system issue was reported and corrected between October and December 2021. The property has also experienced some minor issues requiring municipal attention, such as graffiti (June 2024) and occasional parking violations, though most complaints have been promptly addressed by city services.

Risk rating

How 336 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

Out of 1879 buildings in this neighborhood, 1203 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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.

12-Month severity forecast
No violation 48.2%
Moderate concern 22.9%
Severe concern 28.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
