Initial analysis

The 4-unit, 2-story multi-family residential building at 303-309 30th Ave in the Central Richmond neighborhood has undergone significant recent renovations and faced several concerning maintenance issues. Built in 1921, the property has seen substantial improvements in 2023, including comprehensive kitchen and bathroom remodels in January ($55,000) followed by additional bathroom upgrades in July ($28,192), with associated plumbing and electrical work properly permitted and completed. However, the building has experienced multiple serious maintenance challenges in recent years, particularly in 2023-2024, including seven complaints about water-related issues such as flooding and plumbing problems, concerns about combustible storage in the garage, and security issues with door locks. A cluster of violations in February 2017 related to safety and compliance issues, including smoke detectors and security requirements, were all abated by May 2017. The building has maintained its infrastructure with several water heater replacements (most recently in 2020) and a roof replacement in 2008.

Recent complaint patterns indicate ongoing maintenance challenges, with the most recent issues in early 2024 involving flooding in common areas and plumbing problems. Multiple 311 calls in late 2024 suggest concerns about driveway access issues and environmental concerns. Notably, there were instances of unpermitted work in 2021, though most recent renovations have been properly permitted. The property has a history of fire safety concerns, with three combustible materials complaints filed between 2006 and 2021, though all were marked as corrected. While the building's recent improvements demonstrate investment in maintaining and upgrading the property, the recurring nature of some maintenance issues, particularly water-related problems, is worth noting.

Risk rating

How 303-309 30Th Ave'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
