Room Additions in Canoga Park
Canoga Park room additions run in a fixed order: permit, marked utilities, inspected footings, framing, then the opening into the house once it is dry.
Footings set the pace on a Canoga Park addition, since nothing above them can start until their concrete has cured enough to carry load. Before that dig, LADBS has to issue the permit and underground lines get marked. The trench is then inspected with its steel in place and poured. Framing, roof and the joint to the old house follow in that order, and the opening into the existing rooms comes last.
Before the first footing
LADBS issues the permit once the plans clear review, since Canoga Park lies inside the City of Los Angeles. Then underground utilities are located and marked, the work area is fenced, and floors and walls of the house near the joint are covered. The footing trench is dug to the depth on the drawings, steel and anchor bolts are set, and the inspector signs off before concrete arrives. If the new roof will tie into the old eave, shoring goes in under it before any rafter is cut.
From framing to the opening
With the concrete cured, the sill, floor framing, walls and roof go up and the new shell is wrapped and flashed. The opening into the old house waits until the new room is sheathed, roofed and dry, and shoring carries the old roof while the header goes in. Rough plumbing, wiring and ducts are inspected before insulation, and drywall waits for that sign-off. The quote follows this order line by line, so each cost sits beside the step it pays for.

Room Additions in Canoga Park: questions
Measurement settles it. A test hole reveals the old footing's size and reinforcement, and the engineer runs those against the second floor's weight. A lighter roof covering and wall finish can reduce the demand. Where the footing still falls short, new concrete goes in under the bearing walls as the first construction step.
Order matters here as well. The new floor framing is set to the old floor height and bolted through a ledger, the walls are framed and sheathed, and the roof is tied in and flashed. Only then is the old wall opened, with a header carrying its load and straps joining the top plates.
Yes, when the footing work already has the crawlspace open. Anchors and cripple-wall plywood go in ahead of the new framing, under the same permit, and the inspector sees them at the footing stage. Doing it in that slot avoids reopening the floor at some later date.
