Questions to Ask Before Hiring a Custom Builder

Use current California contract and license guidance to evaluate a custom builder, compare scope, and recognize hiring red flags.

By Corey Abrams, owner of Jencor Construction, Inc. Published October 25, 2026.

The most useful hiring questions reveal how the project will be controlled after the proposal is accepted. A portfolio shows finished work. It does not show the contract, payment schedule, supervision plan, documentation process, or response to changed conditions.

Start with current public records and a written scope. Then test how the builder communicates about the work that cannot yet be known.

Verify the license record

Use the California Contractors State License Board license-check service. Confirm that the business name and license number match the proposal. Review the displayed license status and classification for the proposed work. Do not rely on a number printed in marketing material when the current state record is available.

Ask for current insurance documentation and discuss coverage questions with the appropriate professional. A license lookup and an insurance certificate answer different questions.

Require a detailed written contract

CSLB states that California home improvement projects over $500 require a written contract. The contract should describe the work and materials, include a payment schedule, identify permit responsibility, provide required business and license information, and address completion and warranty terms.

CSLB also states that the down payment for a home improvement job cannot be more than $1,000 or 10 percent of the contract price, whichever is less, and that there is no exception for special-order materials.

Read the full agreement. A polished proposal is not a substitute for the required contract terms and notices.

Ask these operating questions

Who owns the project?

Ask who prepared the scope, who will supervise the site, and who can make decisions when the unexpected appears. Get names and roles.

What is included and excluded?

Ask for a written list covering demolition, protection, temporary conditions, permits, structural work, building systems, finishes, cleanup, and closeout. Identify allowances and owner-supplied items.

How are changes handled?

CSLB says changes to contract price or scope must be made through a written change order signed before the changed work. Ask how the builder describes the change, cost effect, schedule effect, and approval.

How do payments follow progress?

The written payment schedule should connect payments to work or materials. Ask how completion of a milestone will be documented and what remains before the next payment.

How are permits and inspections managed?

Ask who obtains permits, who schedules inspections, and how corrections are tracked. The answer should match the written contract.

What evidence is comparable?

Ask for a project similar in scope, site, and level of coordination. Confirm the builder's role instead of inferring it from photographs.

Red flags that deserve a pause

  • The business name or license information does not match the proposal.
  • The contractor resists a detailed written agreement.
  • Important promises are kept outside the contract.
  • The proposal cannot explain allowances, exclusions, or permit responsibility.
  • Payment requests are disconnected from completed work or delivered materials.
  • The contractor proposes undocumented changes after work begins.
  • No one can identify the accountable site and project lead.
  • The contractor pressures you to sign before you can review records and terms.

One concern may have an explanation. A pattern of unclear answers is itself useful information.

Before signing

Compare contractors on the same scope. Verify the license record. Read every contract term and notice. Put agreed changes in writing. Keep copies of the contract, plans, specifications, payment records, change orders, and correspondence.
