Common questions
Can I add a second story to my Costa Mesa home?
Often yes, but it depends on your lot, existing foundation, and height limits. Your free report tells you whether a second-story addition is realistic for your specific property.
What usually slows down an addition permit?
Missing engineering, like structural or soils reports. Because we provide every discipline in-house, we keep your Costa Mesa permit moving without surprise delays.
Do you design and build the addition too?
Yes. We handle design, engineering, permitting, and construction — so your addition blends with your home and gets approved faster and for less.
