Initial analysis

The 1412 Lyon Street property is a three-unit multi-family residential building located in Lower Pacific Heights, constructed in 1900 and currently owned by the Joelson Family 2009 Trust. The building has undergone several significant renovations and improvements over the past two decades, with the most recent major work being completed in 2006-2007, which included an interior remodel of the top unit (1412-C) with kitchen and living area updates, and electrical system improvements including the installation of new circuits and lighting. The property has a history of addressing structural and safety concerns, with notable work completed in 2003-2004 focused on replacing rear stairs, decks, and addressing foundation issues, although this period was marked by some construction management challenges that resulted in building permit suspensions and violations being filed in March 2003 regarding unauthorized modifications to the deck configuration, new siding, doorway, and window installation work. These violations were ultimately abated by April 2004.

The building's permit history shows consistent maintenance and upgrading of both interior and exterior elements, including window replacements in 2004 and various electrical system enhancements. Several planning records indicate past proposals for additional modifications, including variances for front setback, minimum lot width, and rear yard requirements, though most of these have been marked as closed or withdrawn. The most recent building-related activity recorded was an abandoned vehicle complaint from November 2023, which was promptly resolved by city authorities. A routine housing inspection conducted in 2008 shows compliance with housing standards, and while there was an "illegal unit" complaint filed in 1996, this was resolved in 1997 and does not appear to be related to the current building configuration.

Risk rating

How 1412 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

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 age

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

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 69.1%
Moderate concern 21.9%
Severe concern 9.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
