DIY vs contractor?
DIY savings: 40–70% of contractor cost on labor. Realistic skill threshold: painting, basic plumbing, simple electrical, drywall, flooring. Pro required: structural, gas, complex electrical, HVAC, roofing (warranty + insurance), permits. Permitted work without license risks insurance and resale. Time: hobby DIYers 3–5x slower than pro. Tools and learning curve real.
Permit and code compliance?
Permits required for: structural changes, additions, electrical service changes, plumbing rough-in, HVAC replacement, roof replacement (varies), fence (varies). Cost: $50–2,000+ depending on scope. Skipping permit risks: stop work order, fines, forced removal, insurance denial, resale title issues. Always pull permit; cost is small relative to compliance friction.
