Initial analysis

1407 Lyon Street is a three-unit, three-story multi-family residential building located in San Francisco's Lower Pacific Heights neighborhood. Built in 1900 and currently owned by Mark and Shirley Vandewiel, this property has undergone several significant renovations over the past two decades, with the most recent work occurring in 2024. Current permitted improvements include a kitchen remodel in Unit B (approximately 60 sq ft) with associated plumbing and electrical work, and substantial interior renovations to the primary unit including window and door replacements and railing work, with permits valued at approximately $250,000. The building's history shows considerable investment in maintenance and upgrading systems, including foundational work, termite remediation, and various unit improvements.

The property has a documented history of regular safety inspections by Housing Inspection Services in 2003, 2008, and 2017, with no recent violations recorded. While there was a brief inspection in 1996 regarding an allegedly illegal unit, this was resolved quickly. The building has experienced four fire alarm activations, though none resulted in injuries or significant incidents, and a single gas leak incident was documented. Recent 311 calls from 2020-2022 predominantly relate to parking issues, street cleaning, and a damaged tree, rather than building-specific concerns. The property's maintenance record shows consistent attention to structural and safety elements, with multiple permits focusing on foundational stability, termite issues, and the legalization of an additional unit in 1962. The recent permits for substantial interior improvements suggest ongoing commitment to modernization and upkeep of the building's systems and living spaces.

Risk rating

How 1407 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, 368 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.

Building age

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

Building permits, owner's portfolio

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

12-Month severity forecast
No violation 69.6%
Moderate concern 22.9%
Severe concern 7.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
