Initial analysis

The 257-unit multi-family residential building at 401 3rd Street, constructed in 1997 and owned by Ybc Development Ii Lp, has experienced significant infrastructure challenges in recent years, particularly regarding its elevator systems. Multiple complaints and violations between 2023 and 2024 indicate persistent elevator outages, including three documented failures in 2024 and an urgent complaint in August 2024 highlighting concerns from disabled residents. The building underwent substantial upgrades in 2020, including the installation of a backup generator for emergency elevator power, a new fire alarm system, telecommunications facilities, and various plumbing improvements. However, recurring issues with the hot water system and water supply were noted in 2023 and 2024, with a violation filed in June 2023 regarding water temperature compliance.

The property has a documented history of maintenance challenges, including a mold violation in 2021, and various plumbing and electrical upgrades have been performed over the years. Recent telecommunications equipment upgrades include modifications by AT&T (2024) and Verizon (2022) to the rooftop facilities, suggesting ongoing maintenance of building systems. Several building permits from 2020 show significant infrastructure improvements, including reroofing work, fire safety upgrades, and electrical system improvements such as replacement of multiple sub-panels in 2022. While the building's maintenance history shows regular addressing of various systems, the recurring nature of elevator outages and water-related issues suggests ongoing challenges with infrastructure reliability and resident comfort.

Risk rating

How 401 3Rd 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
