Initial analysis

The property at 488-498 30th Street in Noe Valley is a two-story, 11-unit multi-family residential building constructed in 1906 and currently owned by Richard J Modolo. The building has undergone several significant safety improvements in recent years, most notably completing mandatory soft-story retrofit work in 2019 at a cost of $70,000 to comply with San Francisco building codes. The building has experienced multiple maintenance and safety-related issues, particularly in late 2017 when there were several building violations including problems with hot water availability, electrical systems, weather proofing, fire extinguishers, and handrails - all of which were resolved by December 2017. Additional recent maintenance includes a 2022 sewer and house trap replacement and various plumbing improvements between 2017-2022, including water heater replacement and bathroom remodeling.

The building has a history of fire safety concerns, as evidenced by multiple fire complaints between 2005-2023 involving issues with fire extinguishers, combustible materials, and blocked exits, though most were found to have no merit or were promptly corrected. Recent activity at the property has primarily involved routine maintenance and compliance work, with the most significant recent improvements being related to soft-story seismic retrofitting and various systems upgrades. The property has been the subject of regular housing inspections and routine complaints since at least 1999, with documented issues ranging from inadequate heating and water heater problems to various building code violations, though most recent issues appear to be relatively minor and promptly addressed. The building's current status shows no active major violations or complaints, and it maintains compliance with current soft-story retrofit requirements, having received its Certificate of Final Completion (CFC).

Risk rating

How 488-498 30Th 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.
