Initial analysis

The property located at 1115-1117 Mason Street in Nob Hill is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by the Naprele Trust. The building has undergone several maintenance and improvement projects over the years, with the most recent significant work being electrical repairs to the main service and ground system in 2019, followed by kitchen-related updates in the same year. The building has a documented history of permit-related issues, most notably in 2006 when violations were filed regarding unauthorized remodeling work, leading to a series of expired permits and additional violations in 2013-2014 related to construction work beyond approved scope. A major structural repair was completed in 2004 to address damage from a vehicle incident, costing $15,000.

The property's maintenance record shows regular attention to basic upkeep, including reroofing work completed in 2014 (cost: $7,280). However, there have been recurring issues with unauthorized work and permit compliance, particularly during 2006-2014. More recently, the building has experienced several parking-related incidents, with multiple complaints about blocked driveways between 2021-2024, though these are external to the building's condition or management. A notable violation regarding short-term rentals was recorded, though it was subsequently abated. The most recent building-related incident was reported in January 2025, involving street cleaning issues that were resolved with no work needed. While the property has experienced various compliance issues in the past, recent records (2019 onwards) show no active building violations or complaints directly related to the building's condition or management.

Risk rating

How 1115-1117 Mason 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 1125 buildings in this neighborhood, 101 are predicted to be safer.

Building permits, owner's portfolio

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

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.

Moderate concern 13.2%
Severe concern 5.4%
