Always ensure a contractor is fully qualified to avoid future issues.
Understanding Local Coastal Regulations for ADU Construction

Avoiding Excessive Upfront Payments for ADU Projects

Typical payment terms may include:
- A small deposit (5-10%) upon signing the contract
- Progress payments based on completed milestones

When hiring a contractor, watch out for red flags like requests for large upfront payments, pressure to sign a contract quickly, and vague contract terms.
To protect yourself, negotiate fair payment terms and ensure the contract clearly defines the scope, timeline, and costs.
Avoid large payments before significant progress is made, and always keep records of payments and correspondence.
This ensures transparency and helps safeguard against potential disputes.
