The moving boxes are still in the hallway. The inspection came back clean, the lender signed off, and the closing table felt like the finish line. Then, sometimes as late as six months later, a letter arrives from the insurance company. Not the inspector. The underwriter. It says the policy is under review pending an electrical evaluation, because the home has active knob-and-tube wiring buried somewhere the original inspection didn't fully trace.
For anyone who has just bought a pre-1950s house in Savannah's Historic District, this is not a hypothetical. It is one of two clocks now running on every contributing property in the district, and the two clocks move in opposite directions. One of them can catch you months after you've unpacked. The other one requires paperwork before you've picked up a single tool. Understanding both, and which order they actually run in, is the difference between a renovation that pays for itself and one that quietly costs more than the listing price suggested.
The Inspection and the Insurance Review Are Not the Same Exam
A general home inspection and an insurance underwriting review look similar from the outside. Both involve someone walking through the house with a flashlight. They are not the same process, they are not run by the same person, and they do not run on the same timeline. A home inspector notes what is visible. An insurance underwriter, sometimes weeks or months after closing, decides what the carrier is willing to insure.
For houses built before 1950, which describes a large share of Savannah's historic housing stock, the gap between those two reviews usually comes down to wiring. Knob-and-tube systems, the ceramic-insulator wiring common through the early 1940s, were not built for modern electrical loads and typically lack a ground wire. Most standard-market insurers will not write a policy on a home with active knob-and-tube wiring, regardless of the home's condition otherwise. A dedicated electrical evaluation, separate from the general inspection, is what actually satisfies an underwriter, and a full rewire on an older single-family home typically runs somewhere between $8,000 and $20,000 depending on square footage and how accessible the wall cavities are.
The fix is not complicated. It is sequencing. Order the electrical evaluation during your due diligence period, not after closing, and ask the electrician to document how much of the original wiring is still live rather than just noting its presence. That report is what an insurer and a lender will actually want to see.
The Board That Decides What You Can Change on the Outside
Wiring is not the only gate. Savannah's Historic District Board of Review was established in 1973 to protect the property associated with the Landmark Historic District, and it is composed of nine members appointed by the Mayor and Aldermen, with staff support from the Chatham County-Savannah Metropolitan Planning Commission. The board meets the second Wednesday of every month, and it reviews and grants Certificates of Appropriateness for exterior work within the Savannah Downtown Historic Overlay District.
This is a separate approval from a building permit. A Certificate of Appropriateness governs new construction, material exterior changes, additions, relocation, demolition, awnings, signage, and exterior color changes, unless a specific exemption applies. City ordinance also requires a pre-application conference with planning staff before submitting any Certificate of Appropriateness application that will need full board review, which means the timeline for exterior work includes a conversation with staff before the paperwork even goes in.
Skipping this step does not just risk a fine. It can affect financing timelines, insurance underwriting, and resale disclosure if the work surfaces later during a buyer's own due diligence. If you are buying a contributing structure and plan to touch anything visible from the street, pulling the property's Certificate of Appropriateness history before you close tells you whether prior owners handled their exterior work correctly or left you an unresolved problem to inherit.
The Credit That Runs on the Opposite Clock
Here is where 2026 actually changes the math for Savannah buyers, and it cuts the other way from the insurance timeline.
Georgia's Historic Home Tax Credit Program became available for owner-occupied primary residences that are locally designated or contributing to a local historic district, with rehabilitation work eligible starting January 1, 2026 and applications accepted beginning October 1, 2025. That distinction matters more than it sounds. Previously, a homeowner generally needed the property listed on the National Register of Historic Places, either individually or as part of a National Register historic district, to access the state's rehabilitation tax credit. As of 2026, a home that is simply locally designated or contributing to a local district, without ever going through National Register listing, can qualify for the Historic Home Credit specifically. Georgia's Department of Community Affairs confirmed this expansion is deliberate, noting that many locally designated districts across the state were not previously eligible for state rehabilitation tax credits, and owners of locally listed principal residences may no longer need to complete the National Register process at all.
A separate 2026 bill, HB376, raised the minimum qualifying rehabilitation spend from $5,000 to $25,000 for most certified structures and adjusted the credit percentage going forward, changes that took effect July 1, 2026. Reporting from earlier this year also confirmed the statewide annual cap on historic rehabilitation credits for certified structures other than owner-occupied homes doubled from $30 million to $60 million through 2029.
None of this is unlimited money. Historic Savannah Foundation's Sue Adler put the concern plainly to a Georgia news outlet when the earlier round of legislation passed:
"That's why we wanted more money in the program, because people with big projects are planning things further out. And so we're really concerned about the money that we're not going to have in '26, '27, '28."
The same reporting named several Savannah-area districts now within reach of the credit for owner-occupied properties, including Cuyler-Brownville Historic District, the Streetcar Historic District, formerly known as Mid-City, Ardsley Park-Chatham Crescent Conservation District, and Ardmore Conservation District. That is a wider map than just the postcard squares downtown.
Here is the part that inverts the normal renovation order. To use this credit, the state generally expects a Part A application describing the property's condition and planned work submitted before the rehabilitation begins. Start gutting a kitchen before that paperwork is filed, and the spending on that work may not count toward the credit at all.
What This Actually Means When You're Sequencing a Purchase
Put the two clocks side by side and the friction becomes obvious. The tax credit rewards buyers who apply before they touch the house. The insurance risk tends to surface after they've already moved in. A buyer who closes, unpacks, and starts renovating on their own schedule, the way most people naturally approach a new house, can miss the credit entirely on work they would have qualified for and then get blindsided by an insurance letter for wiring they didn't know was still live.
The order that actually protects both the subsidy and the coverage looks like this before you close, not after:
- Pull the property's Certificate of Appropriateness history from Chatham County-Savannah Metropolitan Planning Commission records to confirm prior exterior work was approved
- Schedule a dedicated electrical evaluation separate from the general home inspection, especially on anything built before 1950
- Decide whether the planned work qualifies for the Historic Home Tax Credit and, if so, prepare the Part A application before any rehabilitation begins
- Confirm whether the property sits in a district where the credit now applies, since eligibility now extends beyond the downtown squares to districts like Ardsley Park-Chatham Crescent and Ardmore
None of these steps are difficult individually. The mistake is assuming they happen in the order a newer home would suggest: inspect, close, then figure out repairs and paperwork as you go. In Savannah's Historic District in 2026, the money and the risk both live in the weeks before closing, just in opposite directions.
Frequently Asked Questions
Does the new Historic Home Tax Credit cover interior renovations? The credit applies to qualified rehabilitation expenditures on a certified structure, and interior work can count when it is part of a substantial rehabilitation that meets the Department of Community Affairs' Standards for Rehabilitation. Confirm scope with the state program before assuming any specific interior project qualifies.
Does every old house in the Historic District automatically qualify for the credit? No. The property needs to be locally designated or a contributing structure within a local historic district, and the rehabilitation needs to meet the substantial rehabilitation threshold under the 2026 rules. Non-contributing structures within the district boundary do not carry the same status.
What happens if renovation work already started before I knew about the Certificate of Appropriateness requirement? Unapproved exterior work can require the city to pause the project during review, and the ordinance includes penalty provisions for work done without an approved Certificate of Appropriateness. If you inherit unresolved prior work as a buyer, resolving it before it affects financing or resale is worth doing early rather than at closing.
