California Regulations - Clean Water Act - Residential Appetite?

Thought I would quiz the panel, to try and find out if their is much of a residential “market” with the extensive regulations, litigious clientele, and minimal barrier to entry and expand my existing Home Improvement company ( I am licensed General Contractor for past 13 years), into more of a recurring service-based business arena with Power-washing/window washing/ and hauling services. What would be the pros/cons of expanding out right now?
