What Home Addition Work Covers
Room additions encompass many different types of construction that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions mean physically extending your home's footprint — either outward. This is not the same as remodeling, which stays inside the current square footage.
These projects require a coordinated effort that brings together architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions touch so many systems, hiring a skilled construction team who can manage all of it is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. They're also a popular choice for homeowners planning to age in place. No matter the size, the process follows a clear set of phases that we have refined over many years.

A basic square addition might start around $150,000–$200,000, while larger additions can run significantly higher. During your initial meeting, we outline costs specific to your goals.
How long does a room addition take to complete?The average home addition project runs approximately four to twelve months from breaking ground to move-in. Larger or more complex additions may take longer. City review and approval can take up a large chunk 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. Skipping permits lead to fines and forced demolition. Our team takes care of this entirely so you're covered from a compliance standpoint.

A renovation works within the existing footprint without increasing total size. Room additions generally involve more extensive construction than finish upgrades.
