The answer
A retail-ready shell with adequate electrical and restrooms typically builds out for $50,000–$150,000. A full renovation of a non-retail building — adding security vestibules, a vault, camera systems and code-compliant restrooms — commonly runs $200,000–$400,000 or more, depending on the municipality's specific security and signage ordinance requirements.
Range reflects C3's Michigan transaction experience, not a published dataset.
Security requirements are municipality-specific
Camera coverage, vault construction, alarm monitoring and even exterior signage restrictions vary by local ordinance, not just state rule, so a build-out budget priced against one municipality's requirements can understate the true cost in another. Price the specific ordinance before finalizing a construction budget.
