Initial analysis

10 Neptune Street is a two-unit, two-story multi-family residential building located in Silver Terrace, built in 1911 and currently owned by Prom Den. The property has undergone several significant improvements over the past decades, with the most recent major work being a $5,000 reroofing project completed in 2020. In 2012, the building received substantial electrical and plumbing upgrades, including a new 100-amp electrical panel and improvements to kitchen and bathroom facilities, which were properly documented and completed. The building's historical permit records show some earlier improvements from the 1980s, including attempts at horizontal extension and room addition work, though some of these permits expired before completion.

The property has experienced a few notable incidents over the past years, including a plumbing issue in December 2010 where water/sewage reportedly affected an adjacent property, though this was promptly addressed within one day. A complaint about possible blight was filed in August 2012 but was marked as not active the same day. More recently, in the January 2025 period, there have been multiple municipal transportation agency complaints related to parking enforcement and illegal parking in the vicinity of the property, with several cases being resolved through officer response or citation issuance. These recent parking-related issues appear to be external to the building itself but could impact resident access to the neighborhood streets. Additionally, there was one fire incident recorded with no civilian injuries, though it was classified as a false alarm or false call. The property has not been involved in any tenant buyouts, except for one unrelated property at 9 Apollo Street in 2022.

Risk rating

How 10 Neptune 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.
