“The contractor selection criterion that matters most and is evaluated least: communication style and responsiveness. Construction projects generate questions daily. A contractor who responds to emails and calls within 24 hours during bidding will do the same during construction. A contractor who takes a week to respond during bidding will take longer when you have a problem mid-project. Test communication patterns before signing.”
Specify a 'substantial completion' date and a daily liquidated damages rate in your construction contract. Liquidated damages ($500–1,500/day is typical for residential) create a financial incentive for the contractor to stay on schedule. Without this provision, schedule delays have no contractual consequence for the contractor.
Go to cslb.ca.gov and search by license number or business name. Verify: the license is current and active, the license class matches the work type (B-General for structural work; C-specialty for trades), insurance and bonding is current, and there are no disciplinary actions or formal complaints on the license record. This 5-minute check should be done before signing any contract for work in Stevenson Ranch.
Based on current Stevenson Ranch market data, the highest-ROI renovation projects are: ADU construction (rental income often achieves 100%+ cost recovery in 7–10 years), kitchen remodeling (60–75% cost recovery at sale), bathroom remodeling (55–70% cost recovery), and outdoor living space additions (very high demand in the Valley's climate). Fire hardening upgrades also provide insurance rate value and market differentiation.
California law (B&P Code 7159) caps home improvement deposits at $1,000 or 10% of contract value, whichever is less.
