Initial analysis

The property at 300-312 Pioche Street in the Portola neighborhood is classified as a multi-family residential building containing two separate structures on one parcel. The complex has faced significant permit and code compliance issues over the years, most notably regarding unauthorized dwelling units and safety violations. In 2022, a major violation was documented (complaint #202296209), revealing unauthorized conversions to multiple dwelling units with illegal kitchen installations, leading to the current permit application (202303274482) to convert an unauthorized dwelling unit to ADU status, with the project currently filed and estimated at $45,427. Earlier, between 2010-2011, the property underwent several attempts to address violations, including work to remove unauthorized kitchens and legalize existing bathrooms (BPA #201104134001), though multiple operational permits were involved, including electrical and plumbing permits to complete necessary modifications. The property has also experienced various safety concerns, including insufficient natural light and ventilation, unauthorized windows, and unauthorized electrical and plumbing installations, which were documented in 2010-2011 violations.

More recent history shows ongoing maintenance and safety concerns, particularly regarding tree maintenance and garbage issues, as indicated by multiple 311 calls from late 2024 to early 2025, including reports of fallen trees and debris. A fire safety complaint about blocked exits was filed in October 2023, though it was determined to be without merit by December 2023. The property has a history of building envelope maintenance work, including roof replacement in 1988 and repairs to dry rot in 1992. In 2017, there was a tenant buyout at a different address (160 Harvard Street) involving four tenants and a payment of $75,000. The current status of the property includes several open maintenance issues as of 2025, particularly related to tree damage and debris management on and around the property.

Risk rating

How 300-312 Pioche 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
79th percentile

Out of 255 buildings in this neighborhood, 54 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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.

12-Month severity forecast
No violation 73.5%
Moderate concern 19.6%
Severe concern 6.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
