Foothill Decks Between the Mountains and the Wash
Duarte is bounded to the north by the San Gabriel Mountains, with Bradbury and Monrovia to the west and Irwindale and Azusa on the other sides. Foothill property means slope, and slope means the water coming off a deck has somewhere to go and gets there fast. Drainage detail matters more here than the brand of coating does.
About six in ten occupied homes in Duarte are owner occupied, 4,581 of them, against 2,934 rented. So most of what we do is homeowner work: a back deck over living space, an entry stair that has gone soft, a balcony that has started staining the stucco below it.
Tear-off is where a deck job stops being clean. A balcony rebuild produces old coating, magnesite or lightweight topping, plywood, framing offcuts, edge metal, railing and sometimes concrete, and all of it leaves the site. In Duarte that is not a background detail, because the debris has to be sorted, weighed and documented, not just hauled.
We plan the debris side at the same time as the work. Separating wood, metal and inert material at the source is far easier than trying to reconstruct diversion paperwork after everything went in one bin. Doing it in that order is what gets a deposit back rather than quietly written off.
On the technical side, foothill decks fail at the same three places: the ledger where the deck ties into the house, the base of every post that penetrates the surface, and the drain or scupper that cannot take a real storm. We rebuild those details rather than covering them.

Permit Experts detailsPulling a Permit in Duarte
Duarte does not do plan check in house. Building and plan check services are provided under a contract with Charles Abbott Associates, managed by the city's Community Development Director. Budget for one more item as well: the city collects a construction and demolition deposit and refunds it on completion with verification of 65 percent diversion, so debris has to be documented rather than just hauled away.

Waterproofing in Duarte: Your Questions
Who actually does the plan check in Duarte?
Building and plan check services here are provided under contract by Charles Abbott Associates, with the contract managed by the city's Community Development Director. It is not an in-house counter, which catches out contractors who have not worked here before.
What is the construction and demolition deposit about?
The city collects a deposit and refunds it on completion once 65 percent diversion is verified. A deck tear-off is mostly wood, metal and inert material, all of it divertible, so we separate at the source and keep the documentation as the job runs.
The balcony is only staining the wall, nothing is dripping inside. Is it urgent?
Staining means water is already getting behind the surface and running somewhere. Nothing is dripping yet because the framing is absorbing it. That stage is a repair. The stage after it, when the ledger has lost its fasteners, is a rebuild.
