Do l have to pay the full cost of the ADU upfront?

August 5, 2025

You don’t have to pay the full ADU cost upfront with Apex Homes. Instead, Apex uses a milestone-based payment schedule that spreads costs across different phases of the project.

How Payments Work

  • $1,000 – Initial non-refundable retainer
  • Initial Deposit (5%) – When you sign the proposal and retainer, covering feasibility studies and site analysis.

  • Permit Submission (5%) – Paid once the design package is submitted to the city for permits.

  • Construction Start (5%) – When on-site building begins.

  • Foundation (15%) – After the foundation is completed.

  • Framing (20%) – Once the structural framing is in place.

  • MEP (20%) – After Mechanical, Electrical, and Plumbing installations are complete.

  • Rough Finish (20%) – Covers drywall, flooring, cabinetry, and interior finishing.

  • Completion (10%) – Final payment upon project completion and cleanup (not dependent on utility activation).

This adds up to 100% of the total project cost, but payments are broken into installments tied to progress .
