Renovation Built Around Decatur's Own Rules
You chose Decatur deliberately. Not just a zip code or a general area, but this specific city with its own building department, its own school district, its own historic preservation commission. And the reason almost always comes back to the same thing: City Schools of Decatur. You paid a premium for this address, and you’re renovating the house to make it work for your family rather than leave it.
Home remodeling in Decatur starts with understanding that the rules here aren’t Atlanta’s rules. The permits go through a different city. The historic district review is handled by a different commission with different guidelines. And if your renovation exceeds 50 percent of your home’s fair market value, Decatur requires green building certification before a permit gets issued. That requirement doesn’t exist anywhere in the City of Atlanta. A renovation contractor who works primarily in Atlanta and doesn’t know about it is going to find out at the permit counter, and at that point you may need to go back and rethink the project design from the beginning.
NewSong Renovations is a design-build remodeling company working on home renovation in Decatur. The Craftsman bungalows that need full systems replacement to match what families paying $700,000 for a school district reasonably expect. The Tudors and English Cottages north of the square with complex rooflines and masonry details. The renovation decisions that have to account for HPC review, green building requirements, and tight lots before the design gets finalized. That’s the work.
Decatur was largely built out in the 1920s, and the dominant home type across most of the residential neighborhoods is the Craftsman bungalow. Brick exteriors, front porches with tapered columns, built-in cabinetry, exposed rafter tails, platform framing, plaster over wood lath. Foundations are typically brick pier-and-beam or continuous brick sitting in Piedmont red clay.
You know what you bought. You love the porch and the built-ins and the hardwood floors. That’s why you’re here.
But here’s what’s behind those walls. Knob-and-tube wiring that was never fully replaced, or was partially replaced in ways that left the old wiring in place behind new surfaces. Cast iron drain lines with a century of buildup. Lead paint on every surface built before 1978. Possible asbestos in floor tile and pipe insulation from any mid-century updates. Subterranean termite damage in the framing, because Decatur’s pre-war homes have had a hundred years of exposure without anyone seeing what was happening inside the walls. Rotten subfloor under bathrooms and kitchens where moisture has been working in silence for decades.
The Tudor Revival and English Cottage homes north of the square are a different project. These rooflines have more intersections, the masonry detailing requires matched materials when anything gets repaired, and the decorative half-timbering may be holding something up that you won’t know about until you start taking it apart. The HPC review process in Decatur’s historic districts applies to both home types, but the Tudor renovation is the more complex one to plan.
For homes in this condition, we build in a contingency of 15 to 20 percent above the base construction estimate. A house this age in Decatur’s clay soil on a pier-and-beam foundation, with systems that were last touched before the Korean War, doesn’t open its walls without a conversation about what’s actually in there.
A kitchen remodel in a Decatur Craftsman bungalow starts the same place it starts in every pier-and-beam home built on red clay: with the floor. These foundations settle unevenly over a hundred years, so the floor that looks level isn’t, and the plumbing that needs to move is behind walls that haven’t been opened since the house was built. Kitchen renovation here means a structural assessment before a design conversation. What are the joists doing. What’s behind the walls where the new layout wants to go. And then the kitchen gets designed around what the house can actually support, not around a rendering made before anyone looked at the subfloor.
Bathrooms in these homes tell you more than kitchens do about what’s actually happened over a hundred years. The cast iron drain lines are corroded from the inside. The subfloor under the original tile has been wicking moisture through failing grout since before anyone who lives in the house was born. And in a home that went through mid-century updates, there may be a layer of vinyl tile over the original, which means asbestos abatement before any new flooring goes in. A bathroom renovation in a Decatur bungalow is a subfloor, drain, and systems project. The new bathroom is what you have when that work is done.
When you take on a whole-home renovation in Decatur, you’re bringing electrical to modern code throughout, replacing plumbing that’s been in place since the neighborhood was new, insulating walls and attics that were built without cavity insulation, and reconfiguring floor plans that made sense in 1924 but don’t support how a family lives now. A whole-house remodel at this scope is also where the green building requirement comes into play. If the renovation value exceeds 50 percent of the home’s fair market value, Decatur requires certification under an approved green building program before a permit gets issued. That requirement has to be planned from the beginning of the design phase, not discovered at permitting.
Home additions on Decatur’s narrow lots have a real constraint problem. A 50 to 60 foot wide lot with side setbacks, rear setbacks, and lot coverage maximums doesn’t leave much room to expand outward. So a second-story addition is often the only real option for gaining square footage without running into the zoning limits. And if the home is in one of Decatur’s local historic districts, the addition design has to go through HPC review before a building permit can be issued. The proportions, the roofline, the exterior materials all have to meet the district’s design guidelines before construction starts.
Basement finishing on Decatur’s hillier lots is more viable than on flat terrain. The Eastern Continental Divide runs through Decatur, creating significant grade changes across short distances. Homes on south-facing slopes often have daylight basements or walk-out lower levels that can become real living space. Basement remodeling that skips moisture management on a hillside lot fails faster than on flat ground, because the water pressure working against the foundation wall is more significant when the grade is working against you.
Exterior renovation in Decatur’s historic districts means working within the HPC’s design guidelines for that specific district. Each of Decatur’s six local historic districts has its own guidelines, so the rules for a home in the MAK district aren’t identical to the rules for a home on Clairemont Avenue. Porch renovation, window replacement, roofing materials, siding, additions: all of it requires a Certificate of Appropriateness before the building permit can be pulled. Interior renovation, kitchens, bathrooms, floor plans, systems: none of that requires HPC review. The COA process applies only to exterior changes visible from a public right-of-way.
For the right lot and zoning configuration, an ADU adds rental income or extended family space while keeping the primary home intact. And historic home renovation in Decatur means working within a preservation framework that’s more specific and more actively enforced than most Atlanta homeowners are used to.
Six local historic districts in Decatur require Certificate of Appropriateness review before exterior renovation work can be permitted: McDonough-Adams-Kings Highway, Clairemont Avenue, Ponce de Leon Court, Parkwood, Old Decatur, and Beacon Hill, which received designation in April 2026.
The Decatur Historic Preservation Commission meets on the third Tuesday of each month. A COA costs $35. Minor work can qualify for a Certificate of Exemption at $10 with administrative approval only. Interior work doesn’t require review. But any exterior change visible from a public right-of-way does: windows, siding, roofing materials, porch modifications, additions, new construction.
Here’s the practical implication. If you’re planning exterior work on a home in one of these districts, the design has to be finalized and submitted for HPC review before you can pull a building permit. That adds time to the front end of the project, and it means design decisions about exterior materials, window profiles, roofline modifications, and addition proportions have to be made with the HPC guidelines in mind from the beginning. A design that gets drawn and then submitted to HPC and rejected for non-compliant materials or proportions costs time and money to revise.
When the person planning the exterior design and the person building it are the same team, the HPC guidelines get accounted for in the design before the first submission. A design drawn without checking the district’s guidelines gets rejected. That rejection costs 30 to 60 days and whatever it takes to revise the drawings. We’ve seen it happen to projects that didn’t need to go through it.
Decatur requires that any renovation exceeding 50 percent of a home’s fair market value be certified under an approved green building program before a permit gets issued. That threshold is determined by DeKalb County tax assessor records or a current appraisal. The most commonly used certifications in this market are EarthCraft and LEED, though a handful of other programs qualify.
For a home valued at $700,000, that means any renovation exceeding approximately $350,000 in construction cost triggers the requirement. A full gut renovation of a Craftsman bungalow in Decatur almost always crosses that threshold.
The certification has to be planned from the beginning of the design phase, not added after the design is done. It changes what insulation you can use, what windows you can spec, how the mechanical systems get designed. It touches everything. A design that wasn’t built around the certification requirements can’t be retrofitted to meet them after the fact without significant redesign.
A remodeling contractor who discovers this requirement at the permit counter isn’t the right contractor for a Decatur renovation. It has to be part of the project plan from the first conversation.
City Schools of Decatur is why most families are here. They paid a significant premium for the address. And so the renovation scope in Decatur is driven by a calculation that doesn’t operate the same way in most markets: the cost of staying is lower than the cost of leaving, even if staying means a major renovation.
A family that paid $700,000 for a Craftsman bungalow in Decatur and needs three bedrooms and two full bathrooms that work for a modern family isn’t going to move to get them. They’re going to add a second-story addition or reconfigure the floor plan, because the alternative is leaving the school district. That math drives renovation decisions here in a way that’s specific to Decatur.
NewSong Renovations is a design-build contractor. Design, budgeting, and construction move through one process with one team. In Decatur, that integration matters for two reasons that don’t exist in the same way anywhere else in the service area.
The first is the HPC review process. When the person designing the exterior work is the same team that’s building it, the HPC guidelines get built into the design before submission. The COA doesn’t come back with corrections because someone drew something without checking the district’s guidelines first.
The second is the green building requirement. When design and construction are integrated, the certification requirements are part of the design from the first conversation, not a compliance problem discovered after the drawings are done. A remodeling company that hasn’t navigated Decatur’s green building ordinance before is going to find out about it at the wrong point in the process.
We require that homeowners move out during major renovations. In a Craftsman bungalow where you’re pulling plaster, replacing electrical and plumbing, and potentially adding a second story, there’s no version of living through that. The project moves faster and the work is better when the house is empty.
We start with a conversation about the house, the district it’s in, and what the renovation needs to accomplish. In Decatur, that conversation also includes what the green building requirement means for this specific project and whether the scope triggers it.

Decatur has more regulatory layers than most renovation markets, and getting them wrong costs time and money at the worst possible point in a project. If you’re planning a renovation and you want to understand what the HPC review, the green building requirement, and the City of Decatur permitting process actually mean for your specific home, that’s exactly what the first conversation is for.
