RAISED FOUNDATION 

This involves grading the ground to ensure that it is level or filling in low spots with soil to create a stable base for the house. Next, the foundation for the house was built. This involves pouring concrete footings and setting the foundation walls. The footings are 18" deep and 18" above ground.

SUBFLOOR & INSULATION

Once the foundation is complete. The next step was to build the floor system. This usually starts with installing a ledger board along the bottom of the foundation walls. The ledger board is a horizontal piece of lumber to which the floor joists will be attached. These are the horizontal structural members that support the floor. They are typically spaced 16 inches or 24 inches apart,

FRAMING

Once the floor was complete, building the wall frames was the next step. This involves standing up the wall studs and attaching them to the top and bottom plates and any intermediate plates that may be required. After the walls are framed, the roof trusses are installed. These are the structural components that support the roof, and they are usually made of wood or steel

FRAMING COMPLETED

After framing, the next step was to install the roof. This involves constructing the roof trusses, which are the structural components that support the roof, and then installing the roof decking, which is the layer of material that forms the actual surface of the roof. Once the roof is complete, the next step will be to install the rough electrical and plumbing.

ROOF

After the roof decking was in place, the underlayment was installed, which is a layer of material that goes under the roofing material and helps protect the roof from the elements. The next step was to install the roofing material itself, which could be asphalt shingles, metal, tile, or another type of material.

FIRE SPRINKLER SYSTEM

The ADU is not located near a fire hydrant; therefore, a Fire Sprinkler system must be installed. It was a requirement made by the city of Whittier before plan approval.  Each room will have two fire sprinklers, and the living room will have 4.

INSULATION 

Per title 24 the ADU features R15 on the wall and R30 on the ceiling. To install insulation for a new house construction, you need to determine the type of insulation, plan the installation, cut and install the insulation, seal gaps, insulate the attic and crawl spaces, and test the insulation. Proper insulation is crucial for an energy-efficient and comfortable home, and following these steps will ensure a well-insulated and efficient new house construction.

ASPHALT-SATURATED PAPER AND LATH

Lath is a construction material used for creating a base layer for plaster or stucco on walls. To install the lath, you need to plan the installation, prepare the surface, install the lath rows, cut and shape the lath, bend it at corners, apply the plaster or stucco, and finish the surface as desired. The process requires precision and attention to detail to ensure a long-lasting, durable finish.

DRYWALL

The drywall installation process has commenced and is anticipated to be completed in a few days' time. Prior to the mud and taping stage, a screw inspection will be conducted to ensure that the appropriate screws were used during the installation process.

2/23/2023

STUCCO

The installation process for stucco involves preparing the surface, applying a scratch coat, followed by a brown coat, and a final finish coat. The stucco is then allowed to cure before it can be painted or finished. It's important to note that the process may vary depending on project requirements and stucco materials used, and professional guidance is recommended.

Rain 

  • The historic California raining season slowed down the construction process but the ADU is almost done

KITCHEN CABINETS

The process of installing kitchen cabinets involves planning and measuring the space, installing a level base, marking the position of each cabinet, installing the upper cabinets first, then the lower cabinets, adding any additional components like drawers and shelves, and finally attaching any trim or hardware. It's important to follow the manufacturer's instructions and take appropriate safety measures while doing so. Having a helper can make the process easier, especially when lifting and positioning the cabinets.
