Home Addition Cost in Los Angeles

Adding square footage is a great way to gain space without moving. Here is what Los Angeles homeowners should expect.

Types of additions

What drives cost

Additions are usually priced by square footage, but foundation work, roofline changes, and tying into existing systems all affect the total. A second-story addition costs more per square foot than a ground-floor one.
