Initial analysis

The property at 1747-1749 Lyon Street is a two-unit, two-story multi-family residential building located in Lower Pacific Heights, owned by the Chiyo Tashiro Trust and constructed in 1902. The building has undergone several significant improvements over the past three decades, with the most recent being a rear entry door replacement completed in March 2024 at a cost of $6,312. Previous notable renovations include a comprehensive kitchen remodel in 2009 featuring non-bearing wall removal, window replacement, and electrical upgrades (completed at a cost of $28,000), and a sewer line replacement in 2013. The building's maintenance history shows attention to structural integrity, with documentation of seismic bolting to foundation in 1989, front stair bracing in 1990, and garage improvements in 1997 (though these permits expired).

The property has experienced some maintenance challenges over the years, including a sewage backup incident in 2012 that affected the basement and required emergency response. While the building itself shows regular maintenance through permits for roofing (2002), plumbing, and electrical work, the surrounding area has experienced various municipal issues documented through 311 calls, including illegal parking incidents, graffiti on signal boxes, and occasional encampments in the vicinity. The most recent infrastructure work (2024) suggests ongoing maintenance attention, though the age of the building means periodic upkeep should be expected. The property's permit history indicates regular maintenance and improvements, with no recent permits suggesting any major structural changes or additions.

Risk rating

How 1747-1749 Lyon St'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 670 buildings in this neighborhood, 107 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.

Estimated permit spend (past 7 years)

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 77.7%
Moderate concern 13.6%
Severe concern 8.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
