Initial analysis

The property at 1628 Balboa Street in the Central Richmond neighborhood is a one-story multi-family residential building constructed in 1917, containing three units and classified as a Flat & Store 4 units or less building. The building's documented history shows several significant events, most notably a concerning pattern of sewage-related issues in 2024, with at least six reported incidents of sewage back-up discharge from the side sewer vent between August and December 2024. This recurring plumbing problem represents the most serious current maintenance challenge facing the property. The building's history includes some renovation work in 2005, when bathroom tiles and sheetrock were replaced at a cost of $1,000. Earlier planning records indicate a failed attempt in 1999 to demolish the existing single-family dwelling and construct a new three-family dwelling on the site.

More recently, in late 2024, there have been general municipal service requests related to transportation and street use, though these are not directly related to the building's condition or habitability. The property's maintenance record shows some activity regarding illegal postings in mid-2024, which were resolved by city authorities, though these incidents appear to be separate from the building's structural and plumbing issues. Despite the significant age of the building, having been constructed over a century ago, the most pressing concerns appear to be the recent sewage system problems that have required multiple interventions and resolutions by PUC - Sewer Operations throughout 2024.

Risk rating

How 1628 Balboa 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.
