Initial analysis

The two-unit residential building at 18-20 Day Street in Noe Valley, owned by John Kerim Frager & Rehamni, was constructed in 1929 and is classified as a two-story flats & duplex structure. The property has undergone significant renovations over the past two decades, with the most recent major work completed in 2020 involving comprehensive kitchen and bathroom upgrades costing $26,000, including new cabinets, tiles, appliances, and fixtures, with corresponding plumbing and electrical work. Earlier improvements between 2003-2006 included substantial electrical upgrades, kitchen renovations, and repairs to rear stairs addressing prior concerns about safety. The building has a history of compliance issues, notably receiving two Notices of Violation in 2003-2004 regarding front exterior stairs and landings, which were subsequently resolved through repairs.

Recent activity around the property, particularly from 2022 to 2025, has primarily involved external maintenance and neighborhood issues, including multiple reports of garbage and debris on the street, sidewalk cleaning needs, and parking violations. Three 911 calls were made in late 2023 regarding street cleaning, graffit removal, and parking enforcement matters. There was also a complaint in April 2020 about non-essential construction work during what appeared to be pandemic-related restrictions, though this complaint was marked as "Not Active." The most recent maintenance work on record is from June 2020, suggesting limited recent internal improvements. Historical records show systematic updates to building systems and living spaces, though there are no records of tenant buyouts or occupancy changes in the available data.

Risk rating

How 18-20 Day 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.
