Initial analysis

The property at 1047-1051 Montgomery Street is a three-unit, three-story multi-family residential building located in Telegraph Hill, built in 1907 and currently owned by Kris F Peradotto Sr. The building has undergone several significant renovations in recent years, including a comprehensive $45,000 renovation of all three bathrooms and kitchens in 2022, window replacement in 2018 (installing 14 wood-clad Jeldwen double-hung windows), and a major structural improvement in 2012 involving the replacement of a failing retaining wall and patio deck costing $55,000. More recently, in early 2023, permits were filed to address leakage issues in two lightwells.

The building has a history of structural and safety concerns that were primarily addressed between 2005-2008. Notable issues included a geotechnical emergency in 2007 regarding hazardous rock formations in the rear yard, which resulted in temporary occupancy restrictions until resolved in July 2008. Multiple violations were recorded during this period, including concerns about fire safety (fire extinguishers, smoke detectors, and fire proofing), building maintenance (wood stairs repairs), and emergency exit requirements - all of which were ultimately abated by July 9, 2008. A 2015 fire safety complaint regarding combustible materials was corrected by January 2016. A more recent issue from 2021 involved unauthorized construction of roof deck modifications, though this complaint was quickly resolved within eight days. The building's maintenance history shows regular upkeep and addressed violations, with no active violations or complaints on record as of 2023.

Risk rating

How 1047-1051 Montgomery 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.
