Initial analysis

The two-unit residential building at 420 Alvarado St in Noe Valley, owned by the Jutta K Neuenburg Living Trust and constructed in 1905, has undergone several significant modifications and faced multiple regulatory challenges over the past decade. Most recently, in early 2021, a new deck was constructed on the second floor at the rear of the building at a cost of $33,000, though this was followed by a complaint in April 2022 regarding unpermitted planter boxes installed around the deck. The property has experienced recurring issues with its rear deck, having faced multiple violations between 2013-2016 related to its construction without proper permits, leading to several notices of violation and requirements for permits to rectify the situation. The building has also undergone important infrastructure upgrades, including a new sewer lateral, house trap, and water service installation in 2019, and the replacement of electrical meter main panels in 2017.

Safety-related incidents have included a fireproofing violation in 2016 requiring repairs to the garage ceiling, which was completed by January 2017. The property has experienced recurring sewer issues, with multiple service calls between 2015-2018 regarding sewage backups from the 4-inch vent. While there have been some maintenance and infrastructure improvements, including deck repairs and various utility upgrades, the property has had its share of compliance challenges, particularly regarding deck-related permits and the associated violation enforcement processes. Recent communications indicate ongoing monitoring of property line and permit compliance issues as of 2022, suggesting that while many past violations have been resolved, some concerns about proper adherence to building codes and property boundaries persist.

Risk rating

How 420 Alvarado 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.
