Initial analysis

The three-story, six-unit multi-family residential building at 477-481 14th Street in Mission Dolores, built in 1906 and currently owned by the John E Wai 1981 Living Trust, has experienced several significant maintenance and safety issues over recent years. Most notably, the building underwent a mandatory soft story retrofit in 2019, which was completed at a cost of $50,000, demonstrating compliance with seismic safety requirements. The property has faced recurring plumbing challenges, including a major sewer lateral replacement in 2016 and multiple complaints about plumbing issues and flooding in 2016 that allegedly affected multiple units, though most of these problems appear to have been addressed through subsequent repairs.

In addition to the plumbing problems, the building has a history of various maintenance issues that have required attention, including water damage repairs, various building code violations, and concerns about fire safety systems. Multiple street space permits were issued in 2019, and several infrastructure improvements were completed, including fire sprinkler installations in 2004 and basement electrical system upgrades in 2003. More recently, in 2024, there have been reports of graffiti and garbage issues outside the building, though these are generally minor compared to past internal maintenance problems. The property has experienced periodic issues with parking violations and double parking in the vicinity, as evidenced by multiple 311 calls, though these are not directly related to building conditions.

Risk rating

How 477-481 14Th 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.
