STEP 3

APPROVED 
PLANS

Once the plans are approved, the homeowner will need to pay for the city and permit fees. Fees will vary in cost depending on the city. Fees for new construction will be expencive

STEP 3

BIDS

It's best to wait until the plans are approved to get bids from contractors or subcontractors. With plans on hand, the homeowner has the power to review bids from multiple contractors. Without plans on hand, the contractor's bid will not be accurate. 

STEP 4 

Review Bids for Framing, Plumbing, Electrical

The most expensive and difficult sections of building an ADU are rough Framing, Plumbing, and Electrical. Consider hiring a Subcontractor with ADU experience. By working with a contractor with ADU experience the homeowner will eliminate a horror scenario.

HOW TO VERIFY A CONTRACTORS LICENSE

Bids should include the contractor's license in their initial estimate. Visit The Department of  Consumer Affairs Contractors State License Board to verify the current status of the contractor license.

CONTRACTOR WITH ADU EXPERIANCE

We highly recommend working with subcontractors with ADU experience. This one critical step will eliminate headaches for the homeowner, especially if building an ADU as an owner-builder. Licensed subcontractors are bonded therefore if anything happens to workers on the job site, the contractor's bond is liable, not the homeowner.
