What Homeowners Ask About Room Additions

People planning room additions usually bring up the same important concerns. Here are honest answers to the most common ones:

Room addition investment levels in San Jose range considerably based on what's being built. A basic square addition might start around $150,000–$200,000, while second-story builds can reach well into the six-figure range. During your initial meeting, we give you a clear breakdown specific to your goals.

A typical room addition build spans four to twelve months from start of construction to completion. Larger or more complex additions can extend the timeline. City review and approval can take up a noticeable share of that total schedule.

Always — any room addition that adds square footage requires permits from the city in San Jose. Skipping permits can result in serious problems at resale. Our team handles all permitting so you don't have to worry about it.

A new-room build physically expands your home's total square footage by extending the structure outside the existing floor plan. A interior update stays inside your current square footage without adding new area. Room additions are typically more extensive construction than a standard remodel.

Matching the existing home is a central focus on every room addition project. Our team sources finishes and architectural details to complement your home's existing style. The finished product is an addition that looks cohesive rather than tacked on as an afterthought.
