Homeowners considering room additions typically come to us with the same recurring topics. These are direct answers to the most common ones:
What should I budget for a room addition?Room addition costs in San Jose depend on several factors based on size, complexity, and finish level. A basic square addition might run from $150,000–$200,000, while second-story builds can reach well into the six-figure range. During your consultation, we provide a detailed estimate specific to what you're planning.
How long does a room addition take to complete?The average home addition project runs approximately four to eight months from start of construction to completion. Multi-room or second-story additions may take longer. The permit process can take up a significant portion of that overall timeline.
Are permits required for home additions?Always — any room addition that adds square footage requires permits from the city in San Jose. Unpermitted additions create serious problems at resale. Our team manages every filing so you don't have to worry about it.
