Decks & Patios in Sunland-Tujunga
Sunland-Tujunga decks and patios detailed so rain drains off the frame, with ember-resistant choices checked for lots in mapped fire hazard zones.
Rain that slips between deck boards lands first on the tops of the joists, and that narrow strip is where a Sunland-Tujunga deck starts keeping water on the move. A self-sealing tape along each joist and beam stops it soaking into the screw holes. Gaps between boards let it fall through, and the ground below is shaped so it drains away from the footings and the house.
From the boards to the ground
Under the frame, the soil is graded to fall away from the foundation and covered with gravel over a weed barrier, so splashback stays off the posts and nothing grows up into the joists. Downspouts that would empty under the new deck are tied into a solid pipe that carries roof water out to a safe outlet. Where the yard tilts toward the house, a shallow swale or a trench drain at the high side catches runoff before it reaches the footings. Post bases hold the wood clear of the concrete so its end grain can dry.
Fire hazard mapping and the underside
Some of Sunland-Tujunga lies inside mapped fire hazard zones, and an address in one of them may have to meet ember-resistance rules. The same gaps that let rain fall through can let embers fall too, which is why the space below a deck on a mapped lot may be enclosed with noncombustible skirting or fine metal mesh. Boards with a fire rating, metal flashing at the ledger and a cover in noncombustible material round out the list. We check the mapping for the address and show the drainage and ember details together on the drawings for LADBS.
Decks & Patios in Sunland-Tujunga: what people ask
Given enough height under the door sill for the framing and a drainage gap, with the surface tipped gently away from the house, the boards can finish just below it. A low sill points toward a landing with a drain at the threshold, so water has somewhere to go besides the door.
Solid roofs throw full shade and send rain to a gutter, which keeps the deck below drier. Louvered panels open for light and can close against a passing shower. Open slats filter sun but let embers and leaves through, so on a mapped lot a noncombustible cover is the stronger choice.
LADBS handles plan review and permits in Sunland-Tujunga for a deck lifted above grade or a patio roof framed into the house. Lots inside fire hazard mapping carry extra material requirements, and those go on the drawings. We confirm the parcel details, prepare the set and see it through filing.
