Initial analysis

The property at 118-120 Porter Street is a 3-unit, one-story multi-family residential building located in Bernal Heights, built in 1928 and currently owned by Mauricio Batlle Tr 2008. The building has a documented history of maintenance and compliance issues, particularly in the early 2000s when multiple housing complaints were filed regarding various interior problems including lead paint hazards, mold, rodent infestations, damaged walls and floors, weatherproofing issues, and kitchen problems. These violations were generally resolved by October 2002. More recent improvements include electrical and plumbing upgrades in 2015, specifically the installation of new laundry facilities and sewer drainage repairs. There was also some unpermitted construction activity reported in August 2015 involving electrical work and sheetrock installation, though this complaint has since been marked as not active.

The building has undergone several documented maintenance improvements over the years, including a vinyl siding installation in 2000 and code compliance work in 1985. Recent fire safety inspections in 2022-2023 identified multiple violations related to unpermitted work, though these were subsequently abated. While the building has experienced various fire department responses, none resulted in injuries and most were related to service calls and alarm system issues rather than significant incidents. The property has received multiple weed and grass violation notices between 2021-2023, suggesting ongoing maintenance challenges in outdoor areas. Recent 311 calls from 2022-2024 have primarily concerned issues outside the building itself, such as illegal parking and city services, rather than internal building problems.

Risk rating

How 118-120 Porter 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.
