Initial analysis

The property at 251-255 Parker Avenue in the Lone Mountain neighborhood is a three-unit, three-story multi-family residential building constructed in 1900, currently owned by a Family Trust entity. The building underwent significant renovations and safety upgrades between 2009 and 2013, including the addition of a third unit, construction of a new three-car garage, comprehensive fire safety improvements with a new alarm system and sprinkler system installation throughout the building, and extensive plumbing and electrical upgrades. The building's systems were modernized with a new 200-amp service upgrade, installation of three 60-amp subpanels, and the addition of multiple safety features such as smoke detectors and monitoring systems.

Recent history shows relatively few issues, with the most recent building violation occurring in 2019 regarding fresh air inlet defects, which was abated within a month. The property has maintained active compliance with safety standards, as evidenced by the completion of major safety systems upgrades in 2012-2013 including fire alarms and sprinklers. Historical complaints from 2007-2008 regarding maintenance issues such as peeling paint, mold, and heating fixtures were resolved, and the building underwent substantial improvements during the 2012-2013 period including complete rewiring, plumbing upgrades, and HVAC system improvements. Recent 311 calls related to the property primarily concern external issues such as parking violations and street maintenance, rather than building-specific problems. The property also completed a 2-lot air space subdivision and various planning requirements associated with its major renovations, demonstrating proper regulatory compliance throughout its history.

Risk rating

How 251-255 Parker Ave'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
35th percentile

Out of 519 buildings in this neighborhood, 337 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 65.8%
Moderate concern 19.2%
Severe concern 15.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
