What it really costs to build and renovate in North Atlanta in 2026
Every serious building or renovation project in Forsyth County and North Fulton starts with the same question: what should I actually budget? Not a national average. Not a number from 2022. A real, current range for this market — where land, labor, and finish expectations are different from anywhere else in metro Atlanta.
This is the first edition of the North Atlanta Custom Build Index, a planning resource from Kade Homes & Renovations. Every number below is a directional 2026 planning range based on current project experience in Cumming, Alpharetta, Milton, Suwanee, and greater Forsyth County. Your project will land somewhere in these ranges depending on finish level, lot conditions, and design complexity.
Custom home building: $250–$450+ per square foot
For a ground-up custom home in North Atlanta, plan on $250 to $450+ per square foot for the structure and finishes. On a typical 4,000–5,000 sq ft home, that translates to roughly $1.2M to $2.2M for the house itself — before land and site work.
What moves you within that range:
- Finish level. The distance between quality-grade and magazine-grade lives in cabinetry, countertops, windows, lighting, and millwork. A kitchen with semi-custom cabinets and quartz is a different budget than full-custom inset cabinets with natural stone.
- Design complexity. Rooflines, ceiling details, curved walls, outdoor living, and multi-level foundations cost more to engineer and build than clean, efficient floorplans.
- The lot. A flat, utility-ready lot in a Cumming subdivision is straightforward. A sloped, wooded lot near Big Creek can add $60,000–$120,000+ in grading, retaining walls, and foundation work before framing starts.
Kitchen renovation: $85,000–$200,000+
A full kitchen renovation in this market — not a refresh, but a real reconfiguration with new cabinetry, countertops, appliances, lighting, and flooring — typically runs $85,000 to $200,000+.
The range is wide because kitchens vary enormously in scope:
- A well-appointed kitchen with semi-custom cabinets and mid-range appliances lands in the $85k–$120k range.
- A high-end kitchen with custom cabinetry, professional-grade appliances, a large island, and designer finishes pushes toward $150k–$200k+.
- Add a scullery — the defining trend of 2026 North Atlanta kitchens — and budget another $25,000–$50,000 depending on size and finish.
The real schedule driver: Custom and semi-custom cabinetry runs 8–12 weeks lead time right now. That single item sets the pace for the entire project. Start selections early.
Primary bathroom remodel: $45,000–$110,000+
A primary bathroom remodel — full gut, new layout, tile, vanity, shower, and fixtures — falls in the $45,000 to $110,000+ range in North Atlanta.
- Standard scope with quality tile, a frameless glass shower, and solid-surface counters: $45k–$65k.
- High-end scope with large-format porcelain, freestanding tub, custom vanity, heated floors, and specialty fixtures: $75k–$110k+.
Tile and fixture selections drive cost more than almost anything else. A $12/sq ft porcelain and a $90/sq ft natural stone look similar on a mood board — the installed cost difference across 200+ square feet is significant.
Home additions: $275–$425 per square foot
Adding square footage — whether it's a primary suite, a second-story addition, or a day-one terrace level — typically costs $275 to $425 per square foot in this market. Additions are more expensive per foot than new construction because they tie into an existing structure, which means matching rooflines, reworking HVAC, and connecting plumbing and electrical to existing systems.
2026 trend note: day-one terrace levels. Homeowners across Cumming and Milton are finishing or adding terrace-level living spaces — home theaters, guest suites, gyms, and entertaining areas — at rates we haven't seen before. If your home sits on a slope, this is often the most cost-effective way to add significant living space.
Realistic timelines by project type
Every project is different, but these planning timelines reflect current North Atlanta conditions:
| Project | Planning + Design | Permitting | Construction |
|---|---|---|---|
| Custom home | 3–6 months | 4–8 weeks | 10–14 months |
| 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 hidden schedule driver across all project types is cabinetry. Whether it's a kitchen, bathroom, or built-ins for a new addition, custom and semi-custom cabinets are running 8–12 week lead times. The best way to protect your timeline is to finalize cabinet selections during the design phase, not after demolition.
Forsyth County and North Fulton permit and HOA guidance
The permitting and approval landscape varies significantly across North Atlanta:
- Forsyth County has a relatively efficient permitting process for residential work, but plan reviews for new construction and major additions can take 4–6 weeks during busy periods.
- Milton has its own design standards that go beyond standard code — setbacks, architectural guidelines, and tree-preservation requirements that affect what you can build and where. Plan for additional review time.
- HOA/covenant review is a step many homeowners forget. If your property has covenants, submit your plans to the HOA before pulling permits. Some HOAs review monthly, so missing a submission window can add 30 days.
Sequencing tip: Start your HOA/covenant review and your permit application in parallel. Waiting for HOA approval before starting the permit process adds weeks you don't need to lose.
2026 trends shaping North Atlanta builds
Three design directions are defining this year's custom builds and renovations:
- Sculleries. The working kitchen behind the showpiece kitchen. Sculleries are now standard in high-end North Atlanta homes — they keep mess, small appliances, and meal prep out of the main kitchen without sacrificing function.
- Day-one terrace levels. Rather than leaving the basement unfinished, builders and homeowners are finishing terrace levels from the start — often as guest suites, home offices, or entertaining spaces with walkout access.
- Warm palettes. The all-white kitchen era is over. Warm wood tones, plaster finishes, unlacquered brass, and earth-toned cabinetry are replacing the cool grays and bright whites of the past decade.
How to use this index
These ranges are planning tools, not quotes. Every project is different, and the right budget for your home depends on your specific scope, selections, and site conditions. Use these numbers to set realistic expectations before your first builder conversation — and be skeptical of any estimate that falls well below these ranges without a clear explanation of what's being excluded.
