Frequently Asked Home Addition Questions

How Much is an Addition in the Bay Area?

The cost varies based on the type of addition and materials used but generally ranges from $250 to $500 per square foot.

By this metric, the cost of a home addition is heavily dependent on what side of the room you add to your home, followed by what finishes you add and the actual design of the room.

How Much Does It Cost to Add an Addition to a House in California?

In California, room additions, on average, cost between $200 and $400 per square foot. These averages are state-wide, and in the Bay Area, we are on the higher end due to the high-demand area we live in.

Is It Cheaper to Add On or Build Up?

Building up is a great option if you lack space. However, building out tends to be more cost-effective and simpler. If you have the space, we recommend building out first.

Is a Home Addition a Good Investment?

With today’s interest rates and real estate costs, a home addition allows you to stay in the home you love but more readily change it to suit your family’s needs.

Is an Addition Cheaper Than Moving?

It depends where you move! Moving is considered one of the most stressful situations we can go through. Adding an addition to your home allows you to skip moving costs and invest that money into making the home you love more dynamic for your family.
