In recent years, Accessory Dwelling Units (ADUs) have gone from niche projects to one of the fastest-growing trends in Bay Area construction. Homeowners, investors, and developers are recognizing the value of ADUs small but powerful additions that add space, flexibility, and property value.



But while the demand is booming, many ADU projects fail to meet expectations because of one critical factor: poor framing. At Calframe Construction Inc., we know that successful ADU construction starts with a strong structural foundation, precise, code-compliant, and built to last.

Why ADUs Are on the Rise

Several factors have fueled the ADU surge across California:



• Housing shortages: Cities like San Jose, Palo Alto, and Los Altos are encouraging ADU builds to expand housing options.
• Flexible living: Homeowners use ADUs for rental income, home offices, or multi-generational living.
• Simplified permits: Recent state laws have made ADU construction faster and more affordable.

With these changes, builders and homeowners alike are rushing to take advantage but the speed of growth has also exposed gaps in quality.

The Common Framing Pitfalls in ADU Construction

ADUs might be smaller than full-sized homes, but they’re structurally complex. Tight spaces, zoning limits, and unique lot conditions require precision framing to make everything fit perfectly.

Here are common mistakes that lead to delays and rework:

• Poor layout alignment with existing structures
• Improper load distribution due to compact design
• Missed inspections because of incomplete code compliance
• Moisture control issues when site elevation isn’t properly managed

Calframe Construction prevents these issues through detailed planning, advanced framing techniques, and tight quality control at every stage.

Calframe’s Approach to High-Quality ADU Framing

Our ADU framing process combines experience, efficiency, and craftsmanship ensuring each unit is structurally sound, visually seamless, and built for long-term performance.

Real-World Example: Palo Alto ADU Project

One of our recent ADU projects in Palo Alto, CA, featured a 1,200 sqft modern accessory dwelling unit with:

• New custom framing
• Tyvek housewrap
• 1×6 Advantage shiplap siding
• Precision trimwork

The result: a clean, durable structure that matched the main residence’s aesthetic while meeting all city requirements completed on time and within budget.

This project perfectly reflects how Calframe Construction approaches ADUs: small-scale builds, big-time craftsmanship.
