Building a custom home is one of the most exciting journeys a homeowner can take — but it’s also one of the most misunderstood when it comes to timelines. At Olson Custom Homes, we believe the best builds start with clear expectations.
So, how long does it really take to build a custom home in Tennessee?
While the average range is 6 to 12 months, the actual timeline depends on factors like design complexity, weather conditions, permitting delays, and site prep. Below, we break down each phase so you know exactly what to expect.
Phase 1: Planning & Design (1–2 Months)
Before any dirt is moved, the process begins with planning. This includes:
- Choosing or customizing a floor plan
- Site evaluation (sloped, wooded, or rocky terrain can require additional prep)
- Design consultations for finishes, cabinetry, and structural needs
- Finalizing your construction contract and budget
At Olson Custom Homes, we walk every client through this step with our in-house design team, ensuring the home fits your land, lifestyle, and long-term vision.
Phase 2: Permits & Pre-Construction (1–2 Months)
This stage involves obtaining local approvals and prepping the site. Tasks include:
- Pulling building permits (varies by county and scope)
- Soil testing, grading, and foundation planning
- Ordering materials and scheduling crews
Pro tip: In high-demand areas like Sevier or Greene counties, permit offices can be backed up — building relationships with local authorities (like we’ve done) helps avoid delays.
Phase 3: Foundation & Framing (1–2 Months)
Once the site is ready, your home begins to take shape:
- Excavation and footings
- Poured foundation or crawl space
- Framing the walls, roof, and general structure
- Initial inspections (framing, plumbing rough-ins, etc.)
Weather can play a major role here. Excess rain or freeze conditions in the mountains can slow progress — but a good builder builds with seasonal timing in mind.
Phase 4: Interior & Systems (2–3 Months)
This is when your home begins to feel real. Work during this phase includes:
- Electrical, plumbing, and HVAC installation
- Insulation and drywall
- Flooring, cabinetry, tile, and painting
- Trim, doors, and hardware
With in-house cabinetry and interior finish teams, Olson Custom Homes keeps this phase streamlined and on schedule — no waiting on third-party vendors.
Phase 5: Final Touches & Walkthrough (2–4 Weeks)
The last stage involves:
- Final inspections
- Landscaping and driveway/grading
- Final cleaning and quality assurance walkthrough
- Homeowner orientation and key handoff
We walk every homeowner through their new home to ensure everything meets expectations — and explain maintenance tips for long-term performance.
Additional Factors That Can Impact Timeline
- Change Orders: Altering designs after construction starts can cause delays. We help avoid this with thorough planning.
- Financing Delays: Construction loans or land financing can impact your timeline if not pre-approved.
- Site Complexity: Rural or sloped properties may require extra excavation or engineering.
