“The framing-to-finish ratio on room additions confuses clients. Framing the new space is 25–30% of the project budget. Everything inside the framing — MEP, insulation, drywall, trim, flooring, painting — is the other 70–75%. Clients who see the frame go up and think the project is nearly done are usually surprised when the budget math arrives.”
For second-story additions in fire zones, confirm the fire sprinkler requirement before design begins. LADBS may require fire sprinklers throughout the entire structure — including the existing first floor — when a second story is added. This adds $8,000–20,000 to the project scope and cannot be designed around.
