Los Angeles ADU Powerhouse
How to Choose an ADU Builder in Los Angeles
The best ADU builder is not the one with the slickest promise or the lowest early number. It is the team that can explain your property, identify risk, clarify scope, coordinate permits, communicate through construction, and stay accountable to the finished result. ADU Powerhouse brings that discipline from 100+ completed ADU projects.

Start with feasibility, not a sales pitch
A credible ADU builder should ask about your address, lot, existing structures, utilities, access, intended use, budget comfort, and timeline before recommending a detached ADU, garage conversion, attached ADU, or JADU.
02
Verify license, insurance, and real scope
Ask for current license and insurance information. Then ask what the proposal includes and excludes: design, engineering coordination, permit support, corrections, utilities, site work, finishes, inspections, and communication.
03
Understand who owns the permit path
If design, permitting, and construction are split across unrelated vendors, homeowners can end up managing the gaps. A design-build team should explain who responds to comments and how approval issues connect back to construction scope.
04
Look for clear communication habits
Ask how often you will receive updates, who your point of contact is, how decisions are documented, and what happens if field conditions change. Weekly updates and clear accountability are not luxuries on an LA ADU project.
05
Use the evaluation as a test
A free property evaluation lets you see how ADU Powerhouse thinks before you hire us. We will discuss the property, compare likely ADU paths, and identify the questions that should shape your next decision.
Questions homeowners ask
The practical questions first.
What questions should I ask an ADU builder?
Ask about feasibility, license and insurance, design ownership, permit support, construction scope, exclusions, communication, and how changes are handled.
Should I choose the cheapest ADU builder?
Not without understanding scope. A lower number may exclude design, utilities, corrections, site work, or finish assumptions that matter later.
Is one-team accountability important?
Yes. It helps reduce handoffs between design, permits, and construction and gives homeowners a clearer point of contact.
