Initial analysis

The 18-unit, 4-story apartment building at 4155 Cesar Chavez Street in Noe Valley, built in 1963, has undergone several significant structural and safety improvements over recent years. Most notably, the property completed its mandatory soft story retrofit in 2016, which included the addition of wood shear walls and steel moment frames at the parking level, achieving Tier 2 certification with the Certificate of Final Completion. The building has also received substantial safety upgrades, including a $55,500 fire alarm system upgrade in 2023 to meet current fire code requirements, with improvements to the fire panel, device compatibility, and the installation of low-frequency sounders in sleeping areas. Several other maintenance and improvement projects have been completed, including the replacement of sliding glass doors (2016), garage door header repairs (2016), and various stucco and structural maintenance work.

The building has experienced multiple safety inspections and violations, particularly in late 2022 when several health and safety issues were documented, including fire alarm maintenance, structural maintenance, and general building safety concerns. These violations were abated by February 2023. The property has a history of fire safety inspections, with recurring issues noted for alarm systems and sprinkler systems between 2015-2023, though most were marked as "Condition Corrected." Prior complaints from 2018 had noted concerns about exterior door locking mechanisms, roof railing, elevator permit status, and trash room door functionality. Recent records show improved compliance with safety requirements, including the resolution of multiple fire violations and regular maintenance of safety systems, though there was a brief period in late 2022-early 2023 when multiple health and safety issues were documented but subsequently addressed. The building appears to be currently maintaining active compliance with major safety requirements, as evidenced by the completion of recent fire alarm system upgrades and the abatement of various violations.

Risk rating

How 4155 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.

Neighborhood percentile
