05 / WHAT IS INCLUDED IN YOUR BUILD

Every construction trade we handle under one contract.

You never have to hire or coordinate separate roofers, framers, or drywallers. Below is the complete structural and finish work our licensed team manages on your ADU or garage conversion.

CLICK ANY CONSTRUCTION PHASE BELOW TO READ DETAILS
C01

Garage Conversion Foundation

Your foundation is one of the most important parts of your ADU. Often overlooked, it supports the entire framing of your property and holds your garage conversion securely in place as the anchor between your walls, ceilings, and the ground below. Our team engineers and pours foundations built to Los Angeles seismic standards so your structure remains level, dry, and structurally sound for decades.

C02

Garage Conversion Framing

Framing is where your garage conversion begins to take shape and your architectural blueprints come to life. We build precision wood and structural steel framing that supports all of your drywall, doors, windows, and roofing, reinforcing existing garage structures or erecting brand new backyard frames to exact engineered specifications.

C03

Garage Conversion Roofing

A roof serves as the top layer of protection for your ADU, guarding against the weather while improving safety, security, privacy, and insulation. We install durable roofing systems, flashing, gutters, and California Title 24 cool roof materials tailored to match your main house and garage conversion structure.

C04

Garage Conversion Insulation

Quality thermal and acoustic insulation keeps your garage conversion at a comfortable temperature all year round, protecting against winter cold and summer heat while blocking outside street noise. A properly insulated ADU is highly energy efficient, meets California Title 24 requirements, and needs very little additional heating and cooling.

C05

Garage Conversion Flooring

The flooring in your ADU provides essential structural support while setting the look and comfort of the entire living space. We install moisture resistant subfloors, luxury vinyl plank, engineered hardwood, and tile designed to withstand heavy daily use, heat, and sound while creating a warm, welcoming home environment.

C06

Garage Conversion Drywall

Professionally hung and finished drywall provides a tight seal against outside air, dust, pests, and moisture, making it much easier to heat and cool your garage conversion. Our crew installs, tapes, textures, and shapes smooth drywall across flat walls, vaulted ceilings, custom arches, and curved architectural details ready for primer and paint.

C07

Garage Conversion Windows & Doors

Windows and doors are essential features of every ADU and must be planned and installed carefully to maximize natural light, cross ventilation, privacy, and curb appeal. We install energy efficient dual pane windows, sliding glass patio doors, and secure entry doors that expand visibility and connect your indoor living space to the yard.

C08

Garage Conversion Painting

Interior and exterior painting defines the finished look of your garage conversion while protecting your structure against UV rays, moisture, mold, wind, stains, and pests. We prep, prime, and apply architectural grade coatings inside and out for long lasting surface durability and a clean, modern finish.

APPROVALS

Turnkey planning & approval coordination

Review property feasibility, 2D/3D architectural plans, structural coordination and Title 24 energy calculations as part of the design package. The appropriate authority reviews the applicable zoning and building requirements for the address. In the City of Los Angeles, LADBS Standard Pre Approved Plans can simplify review of a repeated design, while site specific zoning and foundation matters still require review.

Confirm the proposed plan, material selections and detailed onsite estimate before construction. Discuss the approval submissions, inspection stages, trade responsibilities, schedule and communication arrangements. This connects the service checklist to the actual project and makes the path from first drawing to finished home easier to understand.
