ADU Construction in Lakewood
Lakewood ADU construction drawn for plan check: shear wall nailing, hold-downs and the footing under each wall end shown in full on the set.
Shear wall nailing, hold-down sizes and the footing under each wall end are what a plan checker traces on a Lakewood ADU set, following the load from roof to soil and stopping wherever the drawings leave a gap. If the lot is flat and open, the reviewer also confirms the distances to the side and rear lines and the space kept between the unit and the house. We draw those numbers clearly so the first round of comments stays short.
What the structural reviewer traces
A complete structural set shows the roof framing, a shear wall schedule, every hold-down with its model and anchor, and a foundation plan with footing sizes and rebar. The reviewer checks that the calculations match the drawings and that each shear wall has a footing under it deep enough to keep the hold-down from pulling out. Missing details come back as corrections. We answer each one on the sheet and in a short written response, then resubmit, and the approved set becomes the document every inspector compares the work against.
Setbacks, roof and slab
Side and rear setbacks for a detached Lakewood unit can be as small as 4 feet under state ADU law, and the reviewer measures the drawn distances against the survey lines. Walls that close to a line may need fire-rated construction and limits on openings, which the wall drawings show. For roofing on an inland lot we choose a light, reflective covering over solid insulation. On the ground, a level and firm pad usually takes a slab with a perimeter footing, with the bolts and hold-downs from the structural sheets cast into it.

ADU Construction in Lakewood: questions
On a level, firm pad, a concrete slab poured monolithically with a deepened perimeter footing. Softer soil may call for wider footings or a raised wood floor on stem walls. Either way, the anchor bolts and hold-downs are cast in where the structural sheets place them, so frame and foundation act together.
Possibly. Inspectors and engineers look for a real footing at the slab edge, sound concrete and a sill that can be bolted down. A thin edge pour with little depth means new footing sections under the shear walls. We find out by cutting a small test opening at the edge before pricing the conversion.
Its scope is one story and 500 square feet at the most, and a bigger or two-story design gets its price after a look at the lot. The structural sheets are where a Lakewood plan checker spends time, so we draw the shear walls and hold-downs on them in full.
