AI summary

The property at 3133-3135 Balboa Street is a mixed-use, two-story building constructed in 1925, containing two residential units and commercial space, currently owned by Wong Wing Hong & Sun-Wing Rev. The building's history shows several significant events, with the most recent being two consecutive years of commercial vacancy (2022-2023) that prompted Code Enforcement observations, marking it as a vacant structure. The property underwent a notable renovation in 1999 when a restroom and dispensary were added, along with plumbing and electrical modifications, though a reroofing permit from 1995 is recorded as expired.

The building has experienced recurring issues with illegal postings in 2016 and 2021, which were resolved by the Department of Public Works. There have been two documented instances of sidewalk parking violations (2020 and 2021), though enforcement officers were unable to locate the vehicles in both cases. The property's external environment has required periodic street and sidewalk cleaning, with reports of loose garbage noted in 2009 and 2014. An infrastructure issue was addressed in December 2021 with the replacement of a burnt-out streetlight fuse, representing the most recent maintenance activity associated with the property. While the vacant commercial space and historical compliance issues are noteworthy, the building's permits and maintenance records suggest regular, if sporadic, attention to basic upkeep and modifications over the years.

Risk rating

How 3133-3135 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.
