Are building permits necessary?
Yes! Before starting construction of a new building or structure—or changing the use or occupancy of an existing one—you must obtain a building permit.
Routine maintenance and ordinary repairs generally do not require a permit. However, a permit is required if the work involves:
Removing or altering walls, beams, or structural supports
Changing exits or altering how people leave the building
Adding, replacing, or relocating plumbing, gas, electrical, or mechanical systems that affect health and safety
If you’re unsure whether your project requires a permit, please review the list below and Contact Us for further guidance.
