Does a backup automatically mean the private sewer is broken?
No. Restrictions and public-system conditions can cause similar symptoms. The location and cause need investigation.

Which sewer section is private in Detroit?
A practical guide for Detroit homeowners.
Identify the location of the fault before assuming that the city or the property owner must arrange the work. A backup symptom inside a house does not establish where the restriction began.
Understand the private connection
DWSD describes the building drains and the sewer connection from the structure to the city collection pipe as the property-side responsibility. Its guidance also explains that many connections run toward an alley or former alley.
Report a possible public-system problem
If the event involves street drainage, several properties or water entering while the house is not using fixtures, report those details to DWSD. A utility investigation and a private inspection can answer different parts of the same problem.
Ask the inspection to identify the section
A useful private report records the access point, inspected distance, visible finding and any limit to visibility. A repair proposal should connect the proposed work to that finding rather than using the presence of basement water as proof of a broken lateral.
Check the proposed work before approval
For a repair, clarify the location, method, required coordination and reinstatement scope. Responsibility can be fact-specific. Use the current DWSD guidance and the actual inspection findings when discussing the property.
