Initial analysis

The two-unit multi-family residential building at 536-538 18th Avenue in San Francisco's Central Richmond neighborhood, built in 1914, is currently facing significant building code violations as of December 2024. The active violations, filed on December 26, 2024, include issues with water damage, damaged walls and ceilings, stair and handrail repairs, door repairs, unapproved electrical wiring, and concerns requiring plumbing permit verification. These violations are all marked as active with first notices issued on January 7, 2025, though no final abatement dates are indicated, suggesting ongoing safety and maintenance concerns.

Recent history of the building shows various improvement attempts, including a complete roof replacement in 2021 ($18,500) and a substantial kitchen and bathroom remodel on the third floor in 2021 ($37,500). However, several permits related to these improvements were withdrawn, and the property has a documented history of unauthorized modifications, including an illegal kitchenette installation that was the subject of a complaint in October 2020. There were also multiple housing inspection-related calls in 2024, with the most recent violation indicating serious concerns about water damage, electrical systems, and structural elements. The building's maintenance history includes some positive developments, such as furnace replacement in 2017 and various completed repairs, but the current cluster of active violations suggests a need for focused attention on building maintenance and code compliance.

Risk rating

How 536-538 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.
