Our ADU Framing Services

We focus on strong, custom framing tailored to fit your space perfectly. Our work uses the right materials and methods to build solid structures. We also make sure everything meets safety standards and local codes.

Custom ADU Structural Design

We create framing plans that match your ADU's size and purpose. Our designs consider your property's layout and zoning rules in Orange County. This ensures the ADU fits well on your lot and complies with local regulations.


We work with engineers when needed to address load-bearing walls, roof lines, and openings for doors and windows. This helps avoid problems during construction.


Our design process includes reviewing blueprints with you to confirm dimensions and features. We tailor each plan to balance function and style.

Materials and Techniques for Framing

We use quality wood and metal materials suited to California’s climate. For most projects, we prefer kiln-dried lumber to prevent warping and pest issues.


Our framing techniques include platform framing for efficiency and strength. This method builds each floor separately and supports the levels above.


To improve durability, we apply moisture barriers and use engineered wood products in critical spots. These choices increase longevity and reduce maintenance needs.

Ensuring Structural Integrity

Our team follows strict safety codes and building regulations for all frames. We inspect joints and connectors to make sure every part is secure.


We use hurricane ties and brace walls to resist seismic and wind forces common in Orange County. This provides added protection against natural events.


Regular site inspections during framing guarantee quality control. If we spot weaknesses, we fix them before moving on to the next step.

Our Roofing Solutions for Accessory Dwelling Units

Roofing Materials We Use

We use a variety of roofing materials that suit ADUs well. Common choices include asphalt shingles, which are affordable and easy to install. They work well in the local climate and offer good protection against rain.


Another option is metal roofing, known for its durability and long lifespan. Metal reflects heat, which helps keep the interior cooler during hot summers.


Clay or concrete tiles are ideal for a strong, fire-resistant roof. They also suit California’s architectural look but require careful framing because they are heavier. We help you pick the best roofing material based on your specific ADU design and budget.

Weather-Resistant Installation

Proper installation is key to making roofs last longer under weather stress. We seal edges and joints to stop water from leaking inside. Flashing around vents and chimneys prevents water damage in vulnerable areas.


Our team ensures the roof slope allows quick water runoff. This reduces the risk of pooling water and leaks. We use weather-resistant underlayment as an extra barrier against moisture. This protects both the roof decking and the interior walls below.


In Orange County, where we can have heavy rains and strong sun, these steps protect your ADU from early roof wear and improve its safety.



Energy Efficiency

Energy savings start with choosing materials that reflect sunlight and keep heat out. We recommend light-colored or reflective roofing to reduce cooling costs in the summer.


Proper roof insulation also keeps your ADU comfortable year-round. It prevents heat loss during winter and heat gain during summer. This reduces the need for extra heating or air conditioning.


We install vent systems to help regulate attic temperatures and improve air circulation. These measures increase energy efficiency, lower utility bills, and create a better living environment for your ADU occupants.

Our Expert Siding and Drywall Services


Exterior Siding Options


We offer a variety of siding materials to fit your ADU’s style and needs. These include hardie board, vinyl siding, and wood siding. Each option has different levels of durability, maintenance, and cost.


Hardie board is fire-resistant and lasts long with little upkeep. Vinyl siding is affordable and easy to clean. Wood siding provides a natural look but needs regular care to avoid weather damage.


We handle all siding installation steps. This means preparing the surface, installing siding carefully for a weather-tight seal, and adding trim for a clean finish. Our work helps protect your ADU from moisture and pests.



Professional Drywall Installation


Our drywall services create smooth, even walls inside your ADU. We hang drywall sheets precisely to reduce seams and cracks. Then, we tape, mud, and sand each joint to achieve a perfect surface.


We use drywall types that match your room’s purpose, like moisture-resistant drywall for bathrooms or kitchens. This prevents mold and keeps walls strong over time.


We also clean up thoroughly after installation. This saves you time and keeps your workspace safe and neat as your ADU project moves forward.
