Stratum Cost Segregation · Updated September 27, 2026

Permit categories and historic-building renovations

Charleston provides category criteria for its STR permits. Use the city’s criteria and the property’s actual location when confirming the operating model; a nearby beach town or county address should not be evaluated under a Charleston-city category by default. Charleston short-term rental category criteria.

Define the property study

For an older building with later guest accommodations, separate original building costs from subsequent interior renovations and owner-purchased furnishings. Architectural character does not determine a recovery period. Retain plans explaining permanent partitions and systems, especially when invoices use broad restoration descriptions. The preparer needs to understand what was repaired, replaced, or newly added before approving costs for the study.

Records that resolve the main questions

A scoping example

A contractor restores interior finishes while a designer supplies removable guest furnishings. The combined project budget describes the guest experience but does not explain the individual assets. Reconcile the contractor and designer files separately, then tie them to the owner’s capitalized costs.

Illustrative documentation scenario; not a completed client study or a savings estimate.

Does historic character justify a special reclassification percentage?

No market-wide percentage follows from a building’s age or style. A report should support the actual component costs and functions. Ask for the reasoning behind classifications rather than a promised outcome based on the neighborhood.
