The City of San Diego accepts the County's plans with a 30-day review and asks you to contact the plan's provider first.
The County's plan sets are about 85% complete: the owner adds the plot plan (PDS 090), the stormwater forms, Title 24 energy calculations, truss calculations and the fire district's approval. Printed on every sheet: "By using these standard plans, the user agrees to release the County of San Diego from any and all claims, liabilities, suits, and demands … arising out of the use of these construction documents."
