Initial analysis

The Wong Survivors Trust owns this two-unit multi-family residential building located at 1435 18th Avenue in San Francisco's Inner Sunset neighborhood. This two-story flats & duplex structure, built in 1926, has had several notable maintenance and improvement projects over the years. Most recently, in April 2021, the building underwent significant electrical system upgrades, including the installation of new service equipment with two meter sockets and circuit breaker panels, which was completed successfully. The property has experienced recurring tree-related issues, particularly in recent years, with multiple 311 calls regarding overgrown or damaged trees between 2019 and 2024, including current open cases in 2023-2024 concerning trees impacting communication lines and blocking sidewalks. A relevant infrastructure improvement occurred in 1989 when repairs were made to address a cracked foundation, and an attempted expansion project for additional living space in the basement was proposed but ultimately cancelled.

The building has maintained compliance with its structural and safety requirements, with no major violations or incidents on record. Recent history shows regular maintenance and attention to tree-related matters, with the Department of Public Works taking over street tree responsibilities through the StreetTreeSF program as of 2021. The property has experienced occasional parking-related issues, as evidenced by several 311 calls between 2019 and 2024 regarding illegal parking and vehicles blocking driveways or parking on sidewalks, though these incidents have typically been resolved through enforcement actions. The most recent parking regulation matter was a temporary moving sign request in December 2023, which was denied due to non-payment.

Risk rating

How 1435 18Th 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
