Initial analysis

Located in Clarendon Heights, this three-story, five-unit multi-family residential building was constructed in 1900 and is currently owned by Robert J & Yvette P Dolan R. The property has undergone significant maintenance and improvement work over the past two decades, including multiple window and door replacements, electrical system upgrades, and plumbing enhancements. Major work in recent years includes bathroom and kitchen plumbing installations (2015), window replacements (2014-2010), and a complete electrical system upgrade including fire alarm system installation and 400-amp service modifications (2010-2011). The building has faced several concerning issues, particularly between 2018-2019, with multiple complaints about water intrusion, unauthorized construction work, and potential structural concerns. Notable active complaints from 2015 allege unauthorized structural modifications during what was permitted as a non-structural kitchen remodel, including excavations on a steep slope that potentially compromised neighboring foundations. The building experienced significant plumbing system upgrades in 2014, including copper water line repiping and extensive valve replacements across multiple units. Recent maintenance includes patio door replacement (2014) and ongoing parking-related issues in the vicinity, as evidenced by multiple street use and parking enforcement calls in 2023-2024. The property has a history of responding to building violations, most of which were addressed promptly, though some permits from 2006-2011 expired without completion. The building's recent permit history shows regular maintenance and system upgrades, suggesting active management and efforts to maintain the property, though prior construction-related concerns and water intrusion issues indicate past challenges with building systems and construction modifications.

Risk rating

How 1443-1447 Clayton 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.
