Can you DIY part of a retaining wall construction in San Francisco?

Retaining Wall Construction sits in the middle ground: some parts of the job (demo, prep, finish work) are DIY-feasible, while the technical core is best left to a licensed pro, particularly given San Francisco's permitting requirements. A hybrid approach — self-performing demo and finish work while hiring out the specialized portion — can capture a meaningful share of the roughly 30% potential labor savings without taking on the riskiest part of the job.
