What This Type of Project Covers
Room additions encompass many different types of construction website that include everything from adding a single bedroom to full second-story additions. At their foundation, room additions require adding to your home's existing structure — either outward. This is distinct from remodeling, which works within the existing walls.

How long does a room addition take to complete?Most room additions spans four to eight months from permit approval to final inspection. Custom or specialty additions can extend the timeline. City review and approval typically represents a large chunk of that total schedule.
