Initial analysis

The two-unit residential building at 1719-1721 Lyon Street, owned by David Calef and Viole Krasnic, is a 2-story flats and duplex structure built in 1902 in the Lower Pacific Heights neighborhood. The property has undergone extensive renovations over the past decade, with significant work occurring between 2012-2024. Recent activity includes multiple final inspection approvals in November 2023, followed by substantial plumbing and electrical work in February 2024, including kitchen and bathroom remodels, laundry room updates, and the installation of new systems throughout both units. The building received solar panel installations in 2015 (totaling 8.5 kW across two systems), and major electrical upgrades in 2012-2013 including full rewiring of both units, new subpanels, and installation of modern safety features such as smoke detectors.

Historical records show two notable building complaints: one in 2013 regarding window replacement issues that appeared to violate permit conditions, and a 2004 complaint about inadequate heating that was resolved by the following year, though this reflects an earlier period of heating system challenges. The property has maintained regular compliance with permit requirements, though there have been multiple instances of permit renewal needed for various systems upgrades, particularly in 2013-2014, which had previously expired. Recent 311 calls primarily relate to parking enforcement issues in the vicinity, with no reported concerns about the building's condition or systems in recent years. The property appears to have transitioned to modern systems and infrastructure, with particular attention to environmental sustainability through solar installation and comprehensive systems upgrades.

Risk rating

How 1719-1721 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
94th percentile

Out of 670 buildings in this neighborhood, 40 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.

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 77.4%
Moderate concern 15.5%
Severe concern 7.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
