Questions
Room Additions questions
Does a room addition need a permit?
Yes. Additions always need plans and city approval, and Karp handles the drawings, engineering, permit application and inspections as part of the job.
Can you match the addition to my existing house?
Yes. Roofing, siding, windows and paint are matched to the existing home so the new space reads as part of the original house, inside and out.
Can you add a second story?
Yes. Second-story build-outs are part of the work, with the structural engineering coordinated by us and reviewed by the city.
Will an addition disrupt the rest of the house?
Some, honestly. We explain at the consultation which walls come open and for how long, and the crew keeps the work area contained and leaves it clean each day.
What happens at the first consultation?
We visit, walk the house with you and explain the realistic ways to add the space you want. It is free, takes about 30 minutes, and a written estimate usually follows the next day.
