Recent safety and habitability concerns have been addressed through various permits and corrections.

The building has experienced recurring issues with deck safety, fire alarms, and various maintenance matters, including multiple routine inspections and violations related to fire escape conditions. Several renovation projects have been completed, including kitchen and bathroom remodels in units 316 (2021-2022) and window replacements (2015). The property has a history of building code violations, particularly from 2002-2003, when issues with decks, smoke enclosures, and other structural elements were documented but subsequently abated.

Risk rating

How 4220-4230 Cesar Chavez 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.

Number of units

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Moderate concern 67.5%
Severe concern 17.4%
