How Much Does a Parking Garage Cost to Engineer Per Space?
Parking garage engineering typically costs $800 to $2,000+ per space, depending on the type (surface, above-grade, below-grade) and the systems. The per-space metric normalizes the 200-stall and the 2,000-stall: the engineering intensity following the structure (the below-grade's — the excavation) and the systems (the EV, the lighting). Expect engineering at 5-8% of construction.

What the per-space covers
The structure (the PT — the slabs'; the precast — the double-tees; the durability — the corrosion's), the below-grade (the excavation — the shoring; the waterproofing), the MEP (the ventilation — the CO's; the lighting — the LED's; the EV — the charging), and the circulation (the ramps — the geometry; the wayfinding).
Type effects
The surface (the lot's — the $/space lowest; the grading's), the above-grade (the structure's — the standard; the openness — the ventilation's), and the below-grade (the excavation's — the $/space highest; the waterproofing's). The mixed-use (the podium's — the liner's).
Durability and delivery
The corrosion (the chlorides' — the protection; the sealers'), the maintenance (the 50-year — the design's), and the speed (the precast's — the erection's). The per-space engineering — the 5-8% — is the parking's design investment.
The bottom line
Budget $800-$2,000+/space for parking garage engineering (5-8% of construction) — PT/precast durability, below-grade waterproofing, CO ventilation, and EV charging drive intensity.
