- Collect three or more detailed bids with itemized costs and clear allowances.
- Check license, insurance, references and recent project photos.
- Confirm who pulls permits, and the schedule for inspections.
- Use a written contract with a payment schedule tied to completed work, not dates.
Questions to ask before you hire
- Are you licensed in California and insured?
- Who is on site day-to-day, and how often will you update me?
- What is included in each allowance, and how are overages handled?
- How are change orders priced and approved?
- Will you provide lien waivers as you are paid?
Red flags to watch for
- A large up-front payment far beyond a modest deposit.
- No written contract or vague scope.
- No permits for work that requires them.
- Reluctance to provide references or insurance.
Licensing and verification in California
Contractor licensing is handled at the state level in many states and locally in others, and permits are generally required for structural, electrical and plumbing work. Verify with the California licensing authority and the San Jose building department.
When to schedule
