Initial analysis

The property at 4827-4829 19th Street is a 5-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1908 and currently owned by the John D Moriarty 2012 Revocable Trust, this building has experienced several maintenance and safety issues over recent years. Most notably, there are current concerns about water intrusion and potential mold growth, with complaints filed in 2023 and 2024 regarding roof leaks and water damage. The building has a documented history of lead paint concerns, with violations issued in 2018 regarding peeling paint and lead hazard warnings, though these were formally abated by July 2018.

Earlier building inspections revealed various maintenance issues that were addressed over time, including problems with windows (dry rot, non-functioning), plumbing systems, and security features. A significant cluster of violations was documented in 2002, including issues with mold/mildew, smoke detector requirements, window repairs, hot water storage capacity, sink repairs, egress obstructions, security locks, and paint conditions. While many of these older violations were eventually resolved, the recurrence of water-related issues and recent complaints about mold suggest ongoing maintenance challenges. The building also underwent some external repairs in 2009, with work performed on damaged siding. Recent 311 calls have documented various issues including garbage and debris concerns, and there have been accepted complaints regarding both mold/mildew and pest issues in 2024, indicating continued concerns about building maintenance and environmental conditions.

Risk rating

How 4827-4829 19Th 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.

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.
