Decks & Patios in Pasadena
Cedarline Design Build probes for buried concrete and loose fill before setting piers for a Pasadena deck or patio beside an ADU, with fire zone checks.
Broken concrete from an earlier slab or footing sometimes lies just under a Pasadena lawn, right where a deck pier is meant to go. A probe bar finds it before anything is priced. If it turns up, the pier moves, the beam span changes, or the rubble gets cut out and hauled away, and each of those reshapes the framing plan for the deck or patio beside the ADU.
What the probe turns up
We drive a steel probe at every planned pier spot and along the line of any patio edge. Solid refusal a short way down usually means buried concrete or stone, while a soft spot can point to loose fill. Either one changes the footing. Old rubble can be broken out and the hole backfilled with compacted base, or the layout can shift slightly so the pier lands on native soil. Next to a new ADU we also mark the trench path for its sewer and power, since a pier dropped on that route would block the dig.
Pasadena review and fire rules
Pasadena's own building and safety staff review deck and patio cover plans for lots in the city. Some Pasadena lots fall inside mapped fire hazard zones, and one that does may face ember-resistance rules that limit which boards, cover panels and under-deck enclosures qualify. We check the lot against that map before choosing materials. The reviewer also reads footing depth, beam sizes, guard strength and the setback lines, so the drawing shows each pier where it actually landed after probing. Drawing it this way keeps the inspection from turning up a surprise the paperwork never mentioned.
Decks & Patios in Pasadena: common questions
Start with the doors. Each home gets a paved or decked spot just outside its own entry, and the space between becomes shared lawn or a planted buffer. Where privacy matters more, a low wall or a cover with a slatted side screens one patio from the other.
In Pasadena the city's building staff want drawings for a deck raised above 30 inches, a deck fastened to the house and a patio cover with a roof. A small detached platform close to the ground can fall outside that list, though setback and fire zone rules may still apply.
Yes. Adding the deck and cover to the ADU set lets Pasadena review footing locations and the unit's utility trenches together, so a pier never lands on a planned sewer route. A later deck can still be permitted on its own.
