Important: This is an all-in budget estimator only and is not a binding quote or contract. Final pricing depends on
structural scope, tie-in complexity, utilities (HVAC/electrical/plumbing), inspections, and material selections.
Material sourcing: If finish materials must be purchased by CMP General Contracting, pricing may increase.
Concealed conditions: If hidden conditions are discovered—including electrical wiring deficiencies, plumbing issues, termite damage, moisture intrusion, rot, or structural concerns—additional costs may apply.
Engineering & permits: Additions often require engineering, permit fees, and inspections. These can vary by city and site conditions.
