Covina rejects an incomplete submittal at the counter, so we bring the whole package the first time.
Covina requires a complete submittal package dropped at the Building and Safety counter, and an incomplete drop off gets rejected outright. That sounds minor until it costs a week on a job where a balcony is already fenced off and unusable. We put the full package in the first time.
The city sits at the foot of the San Gabriel Mountains in the San Gabriel Valley, with about 58 percent of occupied homes owner occupied. Foothill runoff plus valley heat is a combination that works on a deck from both directions: months of thermal movement opening up the edges, then water arriving with real momentum.
