A custom home is the most personal—and most complex—project most people ever take on. Knowing how the process works makes it far less stressful and helps you make decisions at the right time.
What does a custom home builder handle?
The builder also coordinates with your architect or designer, the structural engineer, the surveyor, and the building department, so you have one accountable point of contact.
Stage 1: Planning and site due diligence
Before design begins, understand the lot:
- Flood zone and base flood elevation. Check the FEMA flood map. The required finished-floor elevation affects foundation design, stairs, driveways and cost.
- Survey and setbacks. A boundary and topographic survey shows what you can build and where.
- Soils. A geotechnical report may be needed for the foundation design.
- Utilities and access: water, sewer or septic, power, and construction access.
- HOA and deed restrictions: many Naples communities have architectural review boards with their own approvals.
On waterfront lots there may also be seawall, dock and coastal considerations.
Stage 2: Design and engineering
Your architect or designer develops the plans, and a structural engineer designs the structure to meet Florida's requirements. Decide early on:
- Size, layout and number of stories
- Construction type, such as concrete block (CBS), which is common in Southwest Florida, or framed construction
- Impact-rated windows and doors versus shutters
- Roof type and pitch
- Finish level and major selections, which drive the budget
Getting the builder involved during design helps keep plans aligned with your budget.
Stage 3: Permitting
Permit applications go to the City of Naples, Collier County or the relevant Lee County jurisdiction depending on the property. Plan review covers building, structural, flood and site requirements. A Notice of Commencement is recorded before the first inspection (§713.13). Expect comments and revisions—normal on custom homes.
Stage 4: Foundation
Site work, compaction, foundation forming, inspections and the slab come first. An elevation certificate documents the floor elevation for flood compliance and insurance.
Florida building code: wind and flood
The Florida Building Code is among the strictest in the country for wind. For Southwest Florida homes, that affects:
- Wall construction, reinforcement and tie-downs
- Roof structure and connections that resist uplift
- Impact protection for windows and doors
- Flood-resistant materials and elevated equipment
These requirements are inspected at multiple stages, so the builder schedules inspections at the right moments.
Stage 5: Construction
A typical sequence:
- Foundation and slab
- Walls and structure
- Roof framing and dry-in
- Windows and exterior doors
- Rough-ins and inspections
- Insulation, drywall and exterior finishes
- Cabinetry, trim, flooring and interior finishes
- Site work, driveway, landscaping and pool if included
Throughout construction, your builder should provide regular updates, manage change orders in writing and keep the site organized.
Closeout and final walkthrough
Final inspections lead to the certificate of occupancy. Before you move in, walk the home with your builder, create a punch list, and receive warranties, manuals and closeout documents.
How long does it take?
Design and permitting can take months on their own, and construction of a custom home typically runs most of a year or more depending on size, complexity and weather. Your builder should give you a realistic schedule for your specific plans.

Common questions about custom home construction
Should I buy the lot before choosing a builder?
Involving a builder before you buy can help. A builder can review flood zone, elevation, setbacks, soils, and access to estimate how the lot will affect cost—before you commit.
Why are so many Florida homes built with concrete block?
Concrete block (CBS) construction is widely used in Southwest Florida because it performs well in high winds, resists termites and moisture, and is familiar to local trades and inspectors. Framed construction is also allowed when engineered to meet the same wind requirements.
What is an elevation certificate?
An elevation certificate documents the elevation of a building relative to the base flood elevation. It's used to show compliance with floodplain rules and to rate flood insurance.
Can I make changes during construction?
Yes, through written change orders that document the change, cost and schedule impact. Changes are easiest and least expensive early, before the work they affect is built.
