County permits, not city
There is no city hall in Ola. Being unincorporated means Henry County Building and Plan Review, at 140 Henry Parkway in McDonough on 770-288-6051, is the office that covers it. That is a simpler answer than the one in Stockbridge or Locust Grove, where city departments handle their own, and it is the answer for most of the land on the east side of the county.
Bigger houses change the math, not the rate
The per-window price in Ola is the same as anywhere else in Georgia. What differs is how many windows a house has. Out here the houses are generally larger, often two full stories with a basement level, and that turns a routine whole-home quote into a four or five figure difference depending on the count alone.
| Windows | Estimated range at $575 to $1,100 each | Typical of |
|---|---|---|
| 12 | $6,900 to $13,200 | A single-story or modest two-story house |
| 16 | $9,200 to $17,600 | A larger two-story |
| 20 | $11,500 to $22,000 | Two stories with a finished basement level |
| 25 | $14,375 to $27,500 | A big house with multiple elevations of glass |

Our arithmetic on Modernize's Georgia per-window range, August 27, 2026. Estimates for planning, not quotes. Second-story access, shaped units and any carpentry push above these.
Because the totals get large, staging the work by elevation is more common out here than in town. The west and south faces take the hardest sun and usually show failures first, which makes them the sensible place to start. Full numbers and sources are in the cost guide.
The covenant question out here
Several of the planned subdivisions on this side of the county carry recorded covenants with an architectural review step. Keeneland, in the Ola area, is one whose declaration is publicly readable, and like most of them it never mentions windows by name. What it does require is approval for changes that materially alter the exterior appearance of a property, which is where a new window color or grid pattern lands.
Access, height and the practical side
Second-story openings
Larger houses mean more work above ground level, which is a labor question rather than a materials one. Ground conditions matter too: a house set on a slope, over a deck or behind landscaping takes longer to set up around safely.
Long elevations of glass
Rear elevations on bigger houses often carry wide units, bay assemblies or a patio door in the middle of a run. Bay and bow assemblies and patio doors price separately from the standard openings, so ask for them on their own lines.
