ADU Contractor in Pasadena
Build Construction Corporation is a licensed ADU contractor serving Pasadena homeowners. We design, permit, and build backyard ADUs, garage conversions, and home additions that match Pasadena's architectural character.

Pasadena's charming Craftsman and Spanish Colonial neighborhoods provide a great setting for well-designed ADUs. Whether you want a backyard cottage to rent or a guest house for family, we'll help you create a unit that fits your property and meets Pasadena's design standards.
We've worked on multiple ADU projects in Pasadena and understand the City's permitting process, design guidelines, and inspection requirements. From the first feasibility call to final sign-off, we manage every step so you don't have to deal with the red tape.
Pasadena is one of LA County's stronger ADU rental markets. Units typically rent for $2,600 to $3,500 per month — making the investment recoup faster than in many other parts of the region.
