Homeowners planning a whole-home remodel in Cumming almost always open with the same question — how long will this take? The accurate answer is that the calendar isn't really set by how fast a crew can work. It's set by a sequence of Forsyth County approvals, a fixed inspection order, long-lead materials, and a rain pattern that decides when exterior work is possible.
Kade Homes & Renovations publishes the North Atlanta Custom Build Index, a set of directional 2026 planning ranges for this market. It doesn't publish a single number for a whole-home remodel, and that omission is meaningful: a whole-home project is several scopes running in sequence and in parallel, not one line item.
| Scope | Planning + design | Permitting | Construction |
|---|---|---|---|
| Kitchen renovation | 4–8 weeks | 2–4 weeks | 8–14 weeks |
| Primary bath remodel | 3–6 weeks | 2–4 weeks | 6–10 weeks |
| Home addition | 4–8 weeks | 4–8 weeks | 3–6 months |
The Index also names the biggest hidden driver: custom and semi-custom cabinetry is running 8–12 week lead times. If your remodel touches a kitchen, a bath, and built-ins, that lead time sits underneath all of them. Locking cabinet selections during design rather than after demolition is the highest-leverage schedule decision most homeowners make. These are planning ranges, not quotes.
In Forsyth County, the Department of Building and Licensing, Permitting Division issues all building permits, from 2435 Freedom Parkway, Suite 1100 in Cumming. Applications go through the county's Customer Self-Service portal or in person.
Remodels don't all use the same packet. The county publishes separate residential permit types including Residential Renovations (interior renovation to an existing house), Residential Addition, and Residential Basement Finish.
It also helps to know what does not need a permit. Per the county's "Do I Need a Permit?" guide, roofing and re-roofing, siding replacement, painting, tiling, carpeting and trim work don't require one. Interior additions and interior remodels do — as do adding an electrical circuit, a service upgrade, furnace or AC replacement, water heater replacement, plumbing work involving piping alterations, and retaining walls over six feet.
For an addition, the checklist includes a notarized Authorized Agent Form with the contractor's current business and state license, subcontractor affidavits, a scaled site plan, and the approved recorded plat. Worth reading twice: the county states that issuing a permit "does not assure that the building setbacks have been met," and that the owner or permit holder has sole responsibility for confirming compliance.
This is the local sequencing fact that quietly moves start dates. Forsyth County Environmental Health states that if you plan to build or remodel a home served by a septic system, you have to get approval from the environmental health department before you can obtain a building permit — and that it may take twenty business days or more to process an application or review. There's a dedicated Remodel or Addition Application.
That review isn't a rubber stamp you slot in later. It sits ahead of the permit, which sits ahead of everything else.
Forsyth County is explicit: all building permits expire twelve months from the date of issuance. On a large remodel with long-lead cabinetry or custom windows, that's a real constraint. Pulling a permit before selections are settled can burn months of it waiting on deliveries.
The county publishes its residential inspection types, and they run in order — plumbing underground, footing, slab or foundation wall, setback, rough mechanical, rough electrical, rough plumbing and rough framing (or a combination rough), insulation, temp to perm, then final mechanical, electrical, plumbing and building.
Two definitions set the pace. The footing inspection covers "depth, bearing strength of soil, any reinforcement required." Rough framing requires the structure to be "dried in and weather protected," and states plainly that "nothing is to be covered without County approval." Drywall goes up after the inspector signs off, not when the crew is ready.
Failing compounds. The county charges a trade violation fee of $25.00 for the first failed inspection, increasing in $25.00 increments for each subsequent failure of the same type. Power cannot be released without an approved inspection. Final inspections cannot be requested until outstanding fees are paid. A stop work order may be issued for code violations. Occupancy isn't permissible until all inspections and code requirements are met and the county has issued a Certificate of Occupancy. Work is inspected against the current Georgia state minimum standard codes as adopted and enforced by Forsyth County.
The nearest long-record NOAA station with published normals is Gainesville, about 26 miles east of Cumming at similar elevation. Its 1991–2020 normals show 53.16 inches of annual precipitation spread across 81.3 days a year with at least a tenth of an inch of rain. There is no dry season — every month's normal falls between 3.69 and 5.23 inches — and the wettest quarter is January through March, exactly when excavation, footings and site work are most weather-sensitive.
Cold matters less than northern homeowners expect: 51.4 nights a year at or below freezing, but only 1.8 days a year when the temperature never rises above freezing, and a 234-day freeze-free season between a median last spring freeze around March 27 and a median first fall freeze around November 15. Snowfall normal is 1.9 inches.
The practical read is to build wet-weather contingency into any phase that opens the roof, disturbs ground, or ties an addition into the existing structure.
If your house predates 1978 and paid work will disturb painted surfaces, Georgia runs its own version of the federal Renovation, Repair and Painting program — the correct terms here are Georgia-certified Renovator and Georgia-certified Renovation Firm, issued through Georgia EPD.
Asbestos has a harder schedule edge. Under Georgia EPD's rules, any project involving ten or more continuous linear feet or ten or more square feet of asbestos-containing material requires a project notification with fees paid, and there's a ten working day notification requirement before work starts, with the postmark counting as day one. That's two weeks to be found before demolition, not during it.
Flood hazard. Forsyth County defines substantial improvement as repairs, reconstruction, alteration or improvements whose cumulative cost equals or exceeds 50 percent of the market value of the structure — a threshold a whole-home remodel can cross. Where it applies, the lowest floor including basement must be elevated no lower than three feet above base flood elevation or one foot above the future-conditions flood elevation, whichever is higher.
Land disturbance. If the project adds an addition footprint, driveway or retaining wall, Georgia's one-acre erosion exemption doesn't apply within a larger common plan of development or within 200 feet of the bank of state waters, and there's a 25-foot buffer along all state waters. Forsyth's Stormwater Division enforces the local Erosion and Sediment Control Ordinance.
Confirm Environmental Health review early if the home is on septic. Resolve floodplain status in design. Finalize cabinetry and long-lead selections before the permit is pulled, so the twelve-month clock isn't spent waiting on deliveries. Push ground-disturbing and roof-open work away from the wettest quarter where you can. Treat the inspection sequence as part of the schedule, not an interruption to it. Requirements vary by project and property, so your builder should confirm specifics with Forsyth County before work begins.
Kade Homes & Renovations was founded in Cumming in 2008 by Dan Cipriani and works out of an office in downtown Cumming next to the park. If you're mapping out a whole-home remodel in Forsyth County and want to talk through sequencing before committing to a start date, that's a conversation worth having.
