Framing Services for Accessory Dwelling Units

Structural Framing Solutions

Our framing covers every step from the foundation up. We build all walls, floors, and roofs according to your design and local building codes. Our team ensures the structure withstand weather and daily use. We pay attention to details like load-bearing walls and support beams to keep your ADU stable.


We work closely with architects and engineers to follow the exact plans or make adjustments if needed. This helps avoid delays and expensive changes later. Throughout framing, we conduct inspections to meet safety standards and pass permits smoothly.

Materials Selection for ADU Framing

We typically use wood because it is flexible, affordable, and easy to work with. For added durability, we select treated lumber that resists moisture and pests.


In some cases, steel framing may be an option. Steel offers extra strength and fire resistance. We help you decide which material fits your budget and local code requirements the best.


We also pick materials that fit the size and purpose of your ADU. Lightweight materials can speed up construction without sacrificing quality.

Modern Techniques for Efficient Framing

Our team uses the latest framing methods to save time and reduce waste. For example, we employ precision cutting tools that allow us to assemble wall panels off-site. This means less time on your property and faster progress.


We also use advanced fastening systems that improve the frame’s strength while making the build cleaner and safer. Our process minimizes errors and keeps everything aligned for a perfect fit.



By combining skilled craftsmanship with modern techniques, we ensure your ADU framing is done right the first time.

Types of Roofing Systems Offered

We provide several roofing systems so you can pick the best fit for your ADU’s design and location. Common choices include:

  • Asphalt shingles: Affordable and easy to install. They work well in most climates.
  • Metal roofing: Known for strength and long life. Good for heat reflection and resisting rain.
  • Clay or concrete tile: Offers a classic look. Durable and fire-resistant, but heavier.
  • Flat roofs: Ideal for modern ADUs. We use materials like TPO or EPDM for water resistance.

Siding Options and Installation Services

We focus on materials that stand up to weather and provide options to match your style while helping keep energy bills down.

Popular Siding Materials for ADUs

You have several good siding choices for your ADU. Vinyl siding is common because it is low-cost, easy to install, and needs little maintenance. Another option is fiber cement, which looks like wood but resists rot, insects, and fire. It requires less upkeep over time.


For a natural look, wood siding offers beauty and warmth but needs regular painting and sealing. Metal siding, like aluminum or steel, is durable and modern but can be pricier.


We help you pick siding based on your budget, appearance goals, and how much upkeep you want.

Aesthetic Customization and Finishes

Siding says a lot about your ADU’s style. You can choose textures like smooth, rough, or wood grain. Colors range widely, and paint or stain finishes let you customize the look.


We guide you through color matching to ensure your ADU blends or contrasts nicely with the main home or neighborhood. Options like vertical, horizontal, or shiplap siding profiles add distinct visual touches.


Our installation process focuses on clean lines and tight seams to create a polished, durable finish.

FAQs on ADU Framing, Roofing, Siding, and Drywall Service

Hi there! Have some questions about our service? Find the answers below. 

  • What are the critical factors to consider when choosing ADU framing materials?

    When choosing ADU framing materials, structural integrity and local building code compliance are paramount considerations that will determine the overall safety and legal status of your project. Cost-effectiveness must be balanced with long-term durability, as investing in quality materials like engineered wood products or steel can reduce maintenance expenses over time. 


    Environmental conditions, including moisture exposure, termite risk, and seismic activity in your region, should directly influence your material selection to prevent premature deterioration. Finally, construction timeline constraints may favor certain materials, with traditional lumber offering familiarity to crews while alternatives like structural insulated panels (SIPs) can significantly reduce build time.

  • How does the climate impact roofing options for accessory dwelling units?

    In hot, sunny climates, reflective roofing materials like metal with high solar reflectance index (SRI) values or specialized "cool roof" products minimize heat absorption and reduce cooling costs. 


    Cold weather regions benefit from roofing systems with excellent insulation properties and snow-load capacity, with asphalt shingles remaining popular due to their thermal mass and relative affordability. 


    Coastal areas exposed to high humidity and salt air require corrosion-resistant options like stainless steel, aluminum, or certain composite materials that won't deteriorate prematurely. Areas prone to wildfire should prioritize Class A fire-rated roofing materials such as concrete tile, clay tile, or metal to improve structure survivability during ember storms.

  • What are the most durable siding materials for constructing an ADU?

    Describe the item or answer the question so that site visitors who are interested get more information. You can emphasize this text with bullets, italics or bold, and add links.

  • What are the latest drywall installation techniques for ADUs?

    Advanced moisture-resistant drywall products featuring mold-inhibiting technologies are increasingly popular for ADUs, particularly in bathrooms and kitchens where water exposure is common.


    Acoustic optimization techniques like resilient channel installations, double-layer drywall with dampening compounds, and specialized sound-attenuating drywall products enhance privacy between spaces without significant space loss. 


    Prefabricated corner beads and factory-mixed joint compounds with extended working times allow for cleaner installations with fewer callbacks for repairs. Digital measuring tools and laser levels have revolutionized the layout process, ensuring perfectly square corners and eliminating the wavy walls that plagued earlier construction methods.

  • How do building codes affect the construction of ADUs by regional builders?

    Building codes set rules for safety, materials, and size. They vary by city and county. You need a builder familiar with local codes to avoid delays and extra costs. We always ensure your ADU meets all requirements.
