Initial analysis

The property at 539-541 36th Ave in San Francisco's Outer Richmond neighborhood is a 3-story, 2-unit multi-family residential building constructed in 1947, currently owned by Xu Hong. The building has undergone significant improvements and modifications over the past decade, with the most recent work focusing on lightwell framing details, completed in August 2024, and a spiral staircase installation for rear egress completed in 2022. Major renovations have included reroofing in 2021 ($11,500), the construction of a new three-story rear stairway for additional egress ($16,000) in 2021, and substantial plumbing and electrical upgrades between 2014-2017, including bathroom additions, laundry facilities, and service panel upgrades.

The building experienced a series of violations in 2016 that were resolved by December 2018, including issues with broken windows, sanitation concerns, and egress obstructions, which resulted in the property being designated as a nuisance under San Francisco Housing Code Section 1001(d). A more recent complaint was filed in 2023 regarding unauthorized asbestos removal, though this case is listed as not active. The property has had its infrastructure updated with two 100-amp panels and a 200-amp service installation in 2008, indicating efforts to maintain modern electrical capacity. A sidewalk defect was reported and resolved in 2016, involving approximately 130 square feet of damaged pavement. All notable permits and violations have been addressed, with the most recent permits focusing on safety improvements and building code compliance.

Risk rating

How 539-541 36Th 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.
