Initial analysis

The property at 4664 18th Street is a two-story, four-unit multi-family residential building constructed in 1963, currently owned by Survivors Tr-homer Tsu & Ch. The building has experienced recurring maintenance and safety issues over the past few years, with the most pressing concerns being water-related problems. Most notably, there have been multiple water heater issues reported in 2023-2024, including a burst pipe causing flooding around the front door and garage area in December 2023, and accompanying mold concerns. There are also several active violations as of 2023-2024 related to fire safety (including fire extinguisher requirements and documentation), building weatherproofing, and interior maintenance (including cabinet repairs and lighting issues). The building's history includes some major maintenance work, such as a reroofing project completed in 2003 costing $9,870, and stucco wall repairs completed in 1987.

The property has a documented history of maintenance and safety violations requiring attention, many of which are interrelated. Several complaints from 2013 through 2024 highlight issues with the building's overall condition, including problems with security, garbage management, and common areas. A routine inspection in 2008 and a 2000 complaint revealed various safety concerns that required abatement. While some historical violations have been resolved, including a 2021 fire alarm system issue and job site posting violations, there are currently multiple open violations related to fire safety, plumbing, and building maintenance that remain active as of 2023-2024. The building's recent history suggests persistent challenges with water infrastructure and maintenance response times, culminating in multiple complaints about leaks and water heater problems in late 2023 and early 2024.

Risk rating

How 4664 18Th 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.
