Updating a historic-era home near Lawrenceville Square can feel exciting and a little intimidating. You want modern comfort without losing the features that make your home special, and you want to follow the rules that protect the Square’s character. In this guide, you’ll learn how to plan updates that fit local expectations, protect your investment, and tap into potential incentives. Let’s dive in.
Why historic homes around the Square matter
Lawrenceville’s downtown is the city’s historic heart, with landmarks like the Gwinnett Historic Courthouse anchoring community events and identity. The city’s Main Street program and Downtown Development Authority focus on thoughtful revitalization and preservation in the Square. That means your exterior work near the Square is more visible and often reviewed for compatibility with the area’s historic character.

Know the rules before you demo
Local reviews and permits
Before you change siding, windows, porches, or rooflines, check with the City of Lawrenceville’s Planning and Development team. In sensitive downtown areas, exterior changes may require a design review or a Certificate of Appropriateness, along with standard building permits. Starting the conversation early prevents delays and helps you design updates that will be approved.

Standards that shape your plan
Most preservation reviews and all historic tax credit projects use the Secretary of the Interior’s Standards for Rehabilitation. These guidelines favor repair over replacement and encourage keeping character-defining features like original windows, porches, trim, and masonry details. If you plan to pursue tax credits, your work must meet these Standards.

Incentives and financing basics
Georgia state historic rehabilitation tax credit
Georgia offers a state historic rehabilitation tax credit for certified projects. The program has eligibility rules, per-project and annual caps, and a required preapproval and certification process. Documentation and photos matter, so plan ahead and follow the state steps.

Federal historic rehabilitation tax credit
Income-producing historic properties, such as commercial or rental buildings, may qualify for a 20 percent federal credit if the work meets the Standards and is certified. Owner-occupied single-family homes generally do not qualify for the federal credit.

Common issues in Lawrenceville’s historic-era homes
Historic houses near the Square often date to the 19th and early 20th centuries. The climate and original construction methods create predictable repair needs.
Moisture and structure
Clay-rich soils and shallow historic foundations can lead to settlement and cracking. Poor drainage, clogged gutters, and flashing failures allow water to enter crawlspaces and basements. Address drainage, roofing, and foundation issues before cosmetic work.
Termites and pests
Georgia sits in the termite belt. Subterranean termites are common in Gwinnett County, and older wood framing is vulnerable. Look for mud tubes and seasonal swarms, and use licensed professionals for inspection and treatment.

Systems: electrical, plumbing, HVAC
Old wiring, such as knob-and-tube or small panels, may not meet modern safety or insurance expectations. Galvanized or cast iron plumbing can be corroded. For comfort without heavy demolition, consider high-efficiency heat pumps or mini-splits and plan ductwork carefully to avoid cutting historic framing.
Lead paint and asbestos
Homes built before 1978 often contain lead-based paint, and some may have asbestos in floor tiles, pipe wrap, or insulation. When contractors disturb paint in pre-1978 homes, EPA Renovation, Repair and Painting rules apply.
- Lead-safe requirements: EPA RRP Program
Windows, insulation, and energy
Original wood windows are key character features. Preservation guidance encourages repairing sashes, adding weatherstripping, and using storm windows to boost performance. Start with attic insulation and targeted air sealing, then explore efficient HVAC and discreet solar options that do not change the primary facade.
