The brick ranch, modern plan, historic face
Whitlock ranches open beautifully: the kitchen wall comes out (engineered, permitted), the primary bath gets created from borrowed space, and the street face stays exactly as the district expects. Inset or wood-toned cabinetry keeps the kitchen in character — no white-box flips.
The basement studio, done legally
Whitlock listings have marketed full-basement studio apartments. The legal version needs an egress-compliant bedroom, smoke/CO protection, and permits — and any short-term-rental use is a separate City rules question we flag rather than assume. The basement finishing page covers the building side; the in-law suite page covers the use side.
Register status, stated precisely
Whitlock Avenue is a National Register district. National Register listing alone does not impose a local COA on private owners; whether your parcel carries a local designation is checked before design — precision here is what separates a historic specialist from a salesperson.
Permits on Whitlock: City process, checked parcel by parcel
Whitlock Avenue sits inside Marietta city limits, so permits run through the City's SagesGov portal — not Cobb County. The City's published residential formula is $4 per $1,000 of construction cost (labour and materials) plus a $50 base fee, with no separate plan-review fee; on a $40,000 kitchen that is $210 in City permit fees before any trade permits. That maths is quoted in your estimate only after the parcel check confirms your home's jurisdiction and local designation status.
The avenue's stock runs Greek Revival to mid-century on one street, so two Whitlock estimates rarely resemble each other. A 1950s ranch scope centres on systems the ranch was built with — wiring, drainage and single-pane-era windows — while an older two-storey on the same avenue carries preservation carpentry and deeper structural unknowns behind plaster. The audit, not the address, sets the sequence: we open the systems questions first, then price the kitchen and bath you actually see.
