Step-by-Step Home Addition Timeline

1. Planning & Design (2-4 Months)

Before construction begins, a detailed plan is essential. This phase includes:

  • Initial consultation to understand your goals and budget
  • Architectural design and structural planning
  • Zoning & building code compliance
  • Permit applications

2. Site Preparation & Foundation Work (1-2 Months)

Once permits are secured, the site is prepared. This involves:

  • Demolition (if needed)
  • Excavation & foundation pouring
  • Structural reinforcements for second-story additions

3. Framing, Roofing & Exterior Work (2-4 Months)

At this stage, the structure takes shape. Key tasks include:

  • Framing walls, floors, and roof
  • Installing windows and doors
  • Roofing and exterior cladding

4. Electrical, Plumbing & HVAC (1-2 Months)

With the structure complete, interior systems are installed:

  • Electrical wiring, plumbing, and HVAC
  • City inspections to ensure code compliance

5. Interior Finishing & Final Touches (2-4 Months)

The last phase involves insulation, drywall, flooring, and finishes. This is where your new space truly comes to life!
