Initial analysis

The multi-family residential building at 1817 Lyon Street in Pacific Heights is a two-story, four-unit apartment structure built in 1900, currently owned by the McGee/Swain Family Trust. The property has undergone several significant maintenance and improvement works over its lifetime, with the most recent being a filed permit in June 2022 for unit #3 to allow for the use of an ILO (In-Law Unit) within the existing legally permitted structure. The building has received attention to its roofing needs in 1989 and 2007, with both reroofing projects completed at costs of $5,500, and termite repairs were performed in 1995. Historical records also show some interior renovations in 1990 involving bathroom modifications.

The building has undergone several routine housing inspections over the years in 2000, 2008, and 2011, with no active violations noted from these inspections. However, there is an active plumbing-related complaint from 1997 concerning the building's sewer system, which has been documented as having excessive grease issues and connections to neighboring properties through a six-inch clay pipe, requiring multiple instances of snaking and partial replacement of 25 feet of sewer pipe, with the problem recurring despite repairs. The only recent maintenance issue noted was a 311 call in June 2021 regarding illegal postings on street furniture, which was resolved by city cleaning services.

Risk rating

How 1817 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
54th percentile

Out of 963 buildings in this neighborhood, 443 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

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

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 64.8%
Moderate concern 21.2%
Severe concern 14.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
