Key Considerations for New Home & ADU Construction

1. Planning and Design

• Determine Purpose: Define the purpose of the home or ADU—primary residence, rental unit, or guest space.
• Maximize Space: Optimize layouts to make the most of available square footage.
• Aesthetic Harmony: Ensure the ADU complements the style of the main home.

2. Budgeting

• Cost Estimates:
  • New homes: Average costs range from $150–$500+ per square foot, depending on materials, design complexity, and location.
  • ADUs: Costs range from $100,000 to $400,000 for detached units; conversions may be less.
• Hidden Costs: Include fees for permits, utilities, and landscaping.

3. Permits and Regulations

• Local Zoning Laws: Research height restrictions, setbacks, and occupancy limits.
• Utility Connections: Ensure proper water, sewage, and electrical connections.
• Permit Process: Follow steps for plan approval, inspections, and final sign-offs.

4. Construction Methods

• Traditional Build: On-site construction for fully custom designs.
• Prefabricated Construction: Pre-built components assembled on-site for faster builds (common for ADUs).
• Sustainable Practices: Use eco-friendly materials and energy-efficient designs.

5. Key Features to Include

• For New Homes:
  • Open floor plans and natural lighting.
  • Smart home technology (lighting, security, and HVAC control).
  • Energy-efficient systems (solar panels, double-glazed windows).
• For ADUs:
  • Separate entrances for privacy.
  • Compact but functional layouts (kitchenettes, bathrooms, storage).
  • Flexible designs (home offices, guest suites, or rentals).

Step-by-Step Guide to Construction

New Home Construction Process:

1. Land Acquisition: Choose a location and ensure the plot is build-ready.
2. Site Preparation: Clear the site, grade the land, and lay utilities.
3. Foundation Work: Pour concrete or install piers/slabs for the foundation.
4. Framing: Construct the frame for walls, floors, and roof structures.
5. Systems Installation: Add plumbing, electrical, and HVAC systems.
6. Interior and Exterior Finishes: Paint, flooring, cabinetry, and siding.
7. Inspections: Schedule inspections at various stages (framing, electrical, final).
8. Final Walkthrough: Ensure all details meet specifications before moving in.

ADU Construction Process:

1. Planning and Design: Develop a layout that meets ADU size limits (typically 500–1,200 sq. ft., depending on local codes).
2. Permit Acquisition: Submit site plans and get approval from local authorities.
3. Site Preparation: Clear and prepare space for new construction or conversion.
4. Construction: Follow similar steps as new home construction but on a smaller scale.
5. Finalization: Add landscaping and utilities to integrate the ADU with the primary residence.

Challenges and How to Overcome Them

For New Homes:

1. Budget Overruns:
   Solution: Stick to detailed cost estimates and avoid mid-project changes.
2. Delays:
   Solution: Account for weather and supply chain disruptions in your timeline.
3. Regulatory Compliance:
   Solution: Work with experienced architects and contractors familiar with local codes.

For ADUs:

1. Space Constraints:
   Solution: Use multi-functional furniture and vertical storage solutions.
2. Utility Hookups:
   Solution: Hire licensed contractors for proper connections and inspections.
3. Zoning Restrictions:
   Solution: Research local laws or consult professionals during the planning stage.
