Planning and Design

• • Determine the location (side of house, backyard, or through garage)
  • Decide on above-grade or below-grade entrance
  • Create architectural drawings and plans

Obtain Permits

• • Submit drawings and application for a building permit
  • Secure all necessary approvals from local authorities

Site Preparation

• • Conduct initial survey and inspection of the area
  • Mark utilities and ensure safety measures are in place

Excavation

• • Dig the area for the new entrance
  • Excavate to the required depth (typically not less 4 feet below grade for frost protection)

Foundation Work

• • Pour concrete footings
  • Install drainage systems (weeping tile and sump pump)
  • Construct foundation walls using poured concrete or cinder blocks

Waterproofing

• • Apply waterproofing membrane to new foundation walls
  • Install insulation (minimum 30 PSI, typically 50mm thick)

Structural Modifications

• • Cut opening in existing foundation wall for new door
  • Install steel lintels for structural support

Stairway and Landing Construction

• • Build concrete stairs and landing
  • Ensure proper dimensions (e.g., 3×3 landing, wide enough for 34″ entry door)

Finishing Work

• • Install door and frame
  • Add railings and guards for safety
  • Complete any necessary landscaping around the new entrance

Inspections

• • Schedule and pass all required municipal inspections throughout the process

Final Touches

• • Clean up the construction site
  • Ensure proper grading for water drainage away from the entrance
