Common Questions

Home Additions in North Idaho

Do I need a permit for a home addition in Coeur d'Alene?

Yes. Any project that increases the footprint or structural envelope of your home requires a building permit. We handle the entire permitting process with the City of Coeur d'Alene, Post Falls, or Kootenai County to ensure your addition is fully compliant.

Can you add a second story to a ranch-style home?

Yes, "pop-top" additions are a great way to double your square footage without losing yard space. We perform a thorough structural analysis to ensure your existing foundation and walls can support the new load before design begins.

How do you match the new addition to my existing home?

Seamless integration is our specialty. We source matching siding, roofing materials, and windows. Inside, we match trim profiles, flooring, and paint colors so the new space feels like it was part of the original build.

Do you build Accessory Dwelling Units (ADUs)?

Yes, we specialize in building attached and detached ADUs (mother-in-law suites). These are popular in Hayden and Rathdrum for multi-generational living or rental income potential.
