Initial analysis

The three-story, six-unit multi-family residential building at 1828-1830 Clement Street in San Francisco's Central Richmond neighborhood was constructed in 1924 and is currently owned by Frederick Y & Amy C Y Lo. The property has undergone several significant safety and maintenance upgrades in recent years, including a completed $24,335 fire alarm system upgrade in 2024 to comply with current fire code requirements, and a $60,000 soft-story retrofit completed in 2019. Other notable improvements include repairs to the exterior backyard stair in 2021, vinyl siding installation in 2010, and commercial storefront alterations in 1996.

The building has experienced various compliance and maintenance issues over its history, though most have been resolved. Notable past violations include a 2018 soft-story retrofit non-compliance notice (which was subsequently addressed), 2010 lead hazard and exterior paint condition complaints, and multiple fire system-related issues in 2005 that were corrected. Recent building complaints from 2020-2022 included reports of inoperative plumbing, unauthorized construction work, and vacant commercial storefront violations, though these cases are now listed as not active. The property has generated multiple 311 calls in 2024, primarily related to parking violations and street cleaning issues, but these are external to the building itself. The building's current status appears to be compliant with major safety requirements, though its past history suggests periodic attention to maintenance and compliance matters has been necessary.

Risk rating

How 1828-1830 Clement 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.
