Compare the team around one defined ADU concept

Before comparing ADU quotes, homeowners should make sure the architect or designer and the builder are answering the same project. The useful questions cover feasibility, design responsibility, permit work, utilities, site conditions, structural assumptions, energy and fire requirements, finish level, allowances, exclusions, schedule, change control, supervision, inspections, and closeout. A low total is difficult to evaluate when each proposal defines the project differently.

Ask who is responsible for feasibility

Clarify who checks setbacks, site access, existing structures, grade, trees, utility routes, and other property constraints. If soils, structural conditions, or provider requirements need additional investigation, identify who coordinates that work and whether it is included in the proposal.

Separate design scope from permit scope

Ask which drawings, engineering documents, energy information, applications, corrections, agency responses, and revisions are included. A design fee may cover conceptual work without carrying the project through permit approval, while another proposal may include a much broader service.

Knowing where one professional’s responsibility ends prevents gaps later.

Normalize the construction definition

Compare foundation, framing, roofing, windows, exterior finishes, insulation, drywall, cabinets, appliances, plumbing fixtures, electrical fixtures, HVAC, utilities, site restoration, cleanup, and final inspection responsibilities. If owner-purchased items are excluded, list them separately so the total project budget remains visible.

Question allowances before they become change orders

For every allowance, ask what quantity and quality level it assumes, whether tax and delivery are included, whether installation is inside or outside the allowance, and what markup applies if the owner selects something different. Test the allowance against real products before signing.

Review staffing and communication, not only credentials

Ask who will be the day-to-day contact, who manages subcontractors, how often the schedule is updated, how questions are documented, and how decisions are escalated. A builder’s project-management system affects the homeowner experience after the sales conversation ends.

Compare change and payment rules before comparing final totals

Ask how unforeseen conditions are documented, when a change order requires approval, how allowances are reconciled, and what evidence supports progress payments. A transparent contract makes future cost changes easier to evaluate.

Choose the team that makes responsibility visible

The best comparison is one where the homeowner can see who owns each major decision from feasibility through final inspection. DreamPrint’s ADU and JADU guide provides the broader planning framework.
