Our Step-by-Step Home Addition Process

1. Planning and Design
   We start by meeting with you to understand your goals, site conditions, and budget. Our team prepares detailed architectural plans, including floor plans, elevations, engineering specs, Low Impact Development (LID) compliance, and Title 24 energy documents. Once your plans are approved through the City of West Hollywood’s Planning Division and HPOZ Board, we pull the necessary permits and prepare to break ground.

2. Site Preparation and Foundation Work
   Before digging begins, we obtain 811 DigAlert utility clearance. We clear, grade, and prepare the site, then excavate and pour a foundation inspected and approved by city and engineering officials to ensure safety and stability.

3. Framing and Structural Work
   Using high-quality lumber and engineered beams (LVL, PSL, Glulam, or steel), we frame your new addition. We install shear walls, structural hardware, and ensure all elements pass West Hollywood Building & Safety inspections before moving to the next phase.

4. Mechanical, Electrical, and Plumbing (MEP)
   Our licensed professionals install HVAC, electrical, and plumbing systems according to city-approved plans, ensuring seamless integration into your existing home. (In West Hollywood, the Building Safety Division requires separate permits and inspections for each trade discipline.)

5. Rough Inspection
   At this stage, city inspectors verify that framing and MEP installations meet local building codes. Passing the rough inspection allows us to proceed with insulation, drywall, roofing, and exterior applications.

6. Roofing Installation
   We install durable, weather-resistant roofing systems to protect your new space. From waterproof underlayment to custom shingles or TPO flat roofing, every detail is completed with precision. We will coordinate obtain all the clearances with LA City  Planning to approve the color and style of the roof  to meet HPOZ guidelines and release permits. 

7. Window Installation
   Energy-efficient, Title 24–compliant windows are installed to fully weatherproof your structure and optimize energy savings.

8. Exterior Wall Applications 
   We install exterior finishes to match features from the  Craftsman and Period Revival architecture from the 1910s–1930s, while  using modern materials, including:

   • Stucco (e.g., La Habra finishes)

   • Fiber Cement Siding (e.g., Hardie Board)

   • Natural Wood Siding (e.g., LP siding)​

9. Interior Finishes
   Drywall installation, texturing, painting, flooring, doors, and trim bring your space to life. Every detail is installed with craftsmanship and care.

10. Final Inspection and Certificate of Occupancy
    Once construction is complete, we schedule final city inspections. Upon approval, you receive a Certificate of Occupancy (CofO)—making your addition officially ready to enjoy.
