Do I need a permit for window or exterior door replacement in Lakewood?
It depends. Whether window or exterior door replacement needs a permit in Lakewood comes down to the details of your project.
Simple like-for-like replacement may not need a permit in some Colorado jurisdictions, but cutting a new opening, enlarging one, or altering a bedroom egress window usually does. Rules vary because each city or county adopts its own code edition. Bedroom and basement sleeping-room windows must meet emergency escape and rescue (egress) sizing under whichever residential code edition your jurisdiction adopted. Colorado sets no statewide edition, so verify the local requirement before ordering units. Lakewood's exemptions handout treats simple like-for-like window and door replacement as a minor cosmetic change that generally does not require a permit. A permit is typically needed if you enlarge or add an opening, change a structural header, or affect egress in a bedroom or basement. Replacement units in sleeping rooms and basements must still meet emergency escape and egress requirements, so confirm your scope with the Permit Counter. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule.
