Several local factors push Cambridge bathroom remodel pricing above or below the national baseline:
Is Cambridge stricter than Boston on energy code?
Cambridge adopted the Specialized Opt-in Stretch Code in 2023, which means new construction in Cambridge faces higher energy performance targets than the statewide base code, similar to but separate from Boston.
What triggers Cambridge Historical Commission review?
Exterior changes, demolitions, and new construction in a local historic district or on a designated landmark property all trigger review. Interior work is usually exempt unless it affects protected interior features.
