Initial analysis

The property at 1370 18th Avenue is a two-unit multi-family residential building located in the Inner Sunset neighborhood, constructed in 1987 and currently owned by Leung Trust. The building has undergone several significant improvements over the years, with the most recent being a kitchen remodel completed in early 2020 that included cabinet and countertop upgrades, followed by corresponding plumbing and electrical work in January 2021. Prior enhancements include the installation of vinyl siding in 2014 (covering 3677 sq. ft. on multiple sides including the lightwell), and a comprehensive window replacement project in 2010 that involved the installation of 16 vinyl windows and 3 patio doors across both units. The building's initial construction history from 1986 included the demolition of a single-family dwelling and the addition of horizontal extensions on both ground and first floors.

Recent maintenance and service calls for the property have primarily involved exterior issues, with notable recent concerns including an open report from February 2024 regarding a tree allegedly causing property damage, and an open follow-up request from September 2024. The building has experienced various external issues over the past several years, including illegal parking incidents (most recently in July 2024), sidewalk maintenance matters (general cleaning in January 2024), and tree-related concerns (including a vacant tree basin issue reported in February 2022). While there have been reports of graffiti in 2017 and a curb defect in 2015, these issues were addressed according to municipal records. A service request to the Department of Public Health regarding environmental health was made in 2018, though the specific nature of the request was not detailed in the records.

Risk rating

How 1370 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
76th percentile

Out of 1493 buildings in this neighborhood, 358 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 84.5%
Moderate concern 10.7%
Severe concern 4.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
