Savannah Historic District (urban 1800s) and Tybee Island (1990s+ beach) sit in the same Chatham County but produce different cost-seg outcomes. Engine-derived per-fixture comparison.
Before the analysis: the underlying numbers this post draws on come from 5 Savannah-area properties run through the Cost Seg Smart engine, same engine that produces real customer studies. Median Year-1 federal savings is $47,117 at the 37% top marginal bracket with 100% bonus depreciation. Reclassification ratio ranges 15.5% to 24.7%.
Savannah's Historic District is the most architecturally distinctive STR market in the United States, 22 city squares surrounded by 1800s townhomes, Italianate residences, and carriage houses, all under strict historic-preservation review. This shapes the cost-seg case in a specific way: original 1800s structural construction (heart-pine framing, original masonry, period plumbing and electrical) reclassifies poorly. The cost-seg math here is overwhelmingly driven by post-2000 renovation cost, where heavy historic-preservation-compliant renovation work has been layered onto the original structural shells.Georgia's partial decoupling from federal §168(k) is the state-tax wrinkle.

The remainder of this section drills into the specifics that matter for comparison local data. The five fixtures we ran through the engine for Savannah span $525,000 to $985,000 in purchase price across 5 distinct sub-markets, enough variance to draw real conclusions about which scenarios actually produce cost-seg ROI in this market.
Take the Historic District Townhome STR as our anchor example. Purchase price: $985,000. Built 1872, 2400 sqft, SFR operating as a short-term rental, located in Historic District (square-anchored).
The engine determined land allocation of 17.0% using statistical methodology, producing a depreciable basis of $817,747. Of that, the engine reclassified $131,164 into 5-year personal property (FF&E, decorative finishes, certain electrical), $56,057 into 15-year land improvements (paving, landscaping, hardscape, site lighting), and the rest into the 27.5-Year Residential Real Property structural category.
That produces a total reclassification ratio of 23.3%. At 100% bonus depreciation and a 37% federal marginal bracket, the illustrative Year-1 federal tax savings is $70,504. That's the headline number for this fixture.
Contrast that with Victorian District Renovated SFR: $685,000 in Victorian District / Thomas Square, built 1892. Here the engine produced a reclassification ratio of 22.6%, lower than the previous example.
Why? Two reasons. First, the land allocation profile is different, 17.6% here versus 17.0% for the previous example. Second, the engine's treatment of sfr as a furnished short-term rental interacts with the build-year and FF&E density differently across neighborhoods.
The takeaway: in Savannah, the per-fixture variance is real. A median number (22.6% reclass) hides meaningful variation across sub-markets and property archetypes.
Georgia partially decouples from federal §168(k). GA historically required an addback for federal bonus depreciation, with the addback amount recovered over the regular MACRS schedule for state purposes. For 2025+ acquisitions under OBBBA's 100% federal bonus, a portion of accelerated reclassification dollars hit a GA-side timing mismatch. At GA's 5.49% flat rate, the absolute dollar impact is modest but real. The federal §168(k) acceleration is unaffected; only the GA Schedule 1 reconciliation is the variable.
Decoupling: Georgia's bonus depreciation conformity has been modified multiple times. Verify current-year treatment with your CPA. The federal deduction is unaffected.
This affects every cost-seg calculation in Savannah. Because Georgia doesn't fully conform, the federal Year-1 figure shown above is only the federal-only portion. The state benefit is smaller (or different) and your CPA will need to manage the addback at filing time.
City of Savannah operates a Vacation Rental ordinance with permit requirements, density caps in certain residential zones (particularly the Historic District and Victorian District), and annual renewal compliance reviews. The Historic District's STR permit availability is constrained, verify permit availability before underwriting STR-intent acquisitions in the Historic District. Chatham County unincorporated areas and Tybee Island operate distinct STR regulatory regimes. Tybee Island has its own short-term vacation rental ordinance that has been periodically tightened. Historic-preservation review is a real constraint on Historic District and Victorian District renovation, exterior modifications, window replacements, and even paint color changes require Historic Review Board approval. Material participation under §469 is achievable for self-managing owners; document hours contemporaneously.
