Initial analysis

The multi-family residential building at 1120 Shrader St is a 2-story, 4-unit apartment structure built in 1923 in the Parnassus/Ashbury Heights neighborhood, currently owned by the Steve L Walkup Revocable Trust. The property has undergone significant renovations and improvements over the past decade, with major work occurring between 2012-2013 including the installation of a new fire sprinkler system ($5,000) and extensive unit remodels costing $30,000 for kitchen/bathroom updates and window replacements. The building's owner converted a partial first-floor storage area into additional living space in 2011, adding two bedrooms and a bathroom. Infrastructure improvements include a complete sewer replacement in December 2021.

The building has experienced recurring sewer issues, with multiple backup incidents reported between 2015-2022, indicating potential ongoing plumbing challenges. A comprehensive housing inspection in 2003 revealed several fire safety and maintenance concerns, including issues with fire extinguishers, fire proofing, and lead paint hazards, though these were all abated by May 2003. More recent building improvements have focused on unit modernization, including kitchen and bathroom upgrades, electrical system improvements, and plumbing renovations. A routine housing inspection from 2009 remains listed as active, though no specific violations are noted in recent years. The most recent significant work was the 2021 sewer replacement, suggesting attention to infrastructure maintenance, though the recurring sewer backup reports indicate this may continue to be an area requiring monitoring.

Risk rating

How 1120 Shrader 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.

Out of 526 buildings in this neighborhood, 394 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 66.1%
Moderate concern 24.2%
Severe concern 9.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
