What is an ordinary repair?

The State Building Code defines ordinary repairs as "any maintenance which does not affect structure, egress, fire protection systems, fire ratings, energy conservation provisions, plumbing, sanitary, gas, electrical, or other utilities. This has been interpreted to mean that rotted floor boards can be replaced on a deck, but the deck can not be rebuilt without a permit. Also, damaged roof shingles can be repaired, but the entire roof can not be re-shingled without a permit. If in doubt as to how much work can be done under ordinary repairs, contact the Building Department before the start of work.
