Initial analysis

The 4-unit, 4-story multi-family residential building at 1313-1315 Clayton Street in Clarendon Heights, built in 1951, has experienced several significant maintenance and compliance issues over recent years. Most notably, there are currently active complaints from 2024 regarding unauthorized construction work, including deck construction beyond the scope of permitted work and reroofing activities. The property has undergone multiple repair and maintenance projects, including a $10,000 re-roofing project initiated in April 2024, electrical upgrades in 2022, and various repairs related to water damage and weatherproofing requirements. A series of building violations were documented in 2022, including issues with the deck, fire safety concerns, and problems requiring electrical work, though some earlier violations related to roof and wall repairs were abated by August 2022.

The building's maintenance history includes plumbing work involving water heater installations, gas line modifications, and repairs to house traps, with some work performed without proper permits. Previous improvements included siding replacement, patio door upgrades, and deck repairs, though some of these projects sparked complaints about unauthorized work in 2022. The property has also faced several habitability issues, including water intrusion, mold concerns, and various maintenance needs, though many of these problems appear to have been addressed through subsequent repairs and permit work. Recent 311 calls regarding the property have primarily concerned external issues such as graffiti and debris, with a pavement defect issue reported and currently open as of April 2024.

Risk rating

How 1313-1315 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.
