Room additions are a broad category that span everything from building an attached garage to large-scale family room builds. At their heart, room additions involve expanding your home's footprint — either horizontally click here or vertically. This is distinct from remodeling, which reconfigures the existing walls.

What should I budget for a room addition?Room addition pricing in San Jose range considerably based on what's being built. A basic square addition might start around $150,000–$200,000, while complex custom expansions can reach well into the six-figure range.

How many months does a room addition project take?The average home addition project spans four to ten months from permit approval to final inspection. Larger or more complex additions can extend the timeline. City review and approval typically represents a noticeable share of that overall timeline.

How does an addition differ from remodeling?A home addition physically expands your home's total square footage by constructing new space outside the existing floor plan.

Can you blend the addition with the existing home style?Matching the existing home is one of our core goals on every room addition project.
