Initial analysis

The two-unit residential building at 123-125 18th Avenue in the Lake-Presidio neighborhood, owned by the Jerry Lynch Living Trust, is a two-story flats and duplex structure constructed in 1921. The property has undergone recent improvements in March 2023, with two significant window and door replacement projects being permitted and issued. These improvements include the installation of three new front-facing wood windows featuring different configurations and grid designs, as well as the replacement of three front sliding doors with French casement windows, all utilizing energy-efficient Lowe dual-panel glass, with an estimated total cost of $22,068.

The building's history includes one notable complaint from July 2007 regarding a possible illegal third unit at the side of the garage, though this complaint was marked as abated by July 2009 and is currently listed as not active. While there was one 311 call in September 2021 relating to hazardous glass materials on the street or sidewalk near the property, this issue was resolved and closed. The recent window and door replacements suggest ongoing maintenance and improvements to the property, though the building's overall permit and complaint history appears relatively limited for its age and location.

Risk rating

How 123-125 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

Out of 660 buildings in this neighborhood, 92 are predicted to be safer.
