So, you're thinking about adding an ADU to your property here in Beaverton. Smart move. Whether it's for family, rental income, or just extra space, an ADU can be a game-changer. But picking the right contractor? That's where a lot of folks stumble. You don't want to end up with a half-finished job or, worse, a shoddy build that costs you more down the line.

I've been in this business a long time, seen a lot of good work and a fair bit of bad. Here's what you need to know to protect yourself and make sure you hire someone who knows what they're doing.

What to Ask Potential Contractors

When you're talking to contractors, don't be shy. This is your money and your property. You need to feel comfortable with who you're letting onto your land. Here are some key questions I'd ask:

  • "How many ADUs have you actually built in Beaverton or the surrounding area?" You want someone with specific experience with these types of projects, not just general home remodels. ADUs have their own set of rules and challenges, especially with local permitting.
  • "Can I see your license and insurance?" Don't just take their word for it. They should be able to provide proof of an active CCB (Construction Contractors Board) license and general liability insurance. No license, no deal.
  • "Who will be my main point of contact throughout the project?" You need to know who to call when you have questions or concerns. A good contractor will have a clear communication plan.
  • "How do you handle changes to the scope of work?" Things can change during a build. You need to understand their process for change orders, how they're priced, and how they're approved. This prevents nasty surprises.
  • "What's your typical timeline for an ADU of this size?" They should give you a realistic timeframe, not just what you want to hear. Building an ADU isn't a weekend job.
  • "Can you provide references from recent ADU clients?" And then actually call those references. Ask them about communication, quality of work, adherence to budget, and how problems were resolved.
  • "How do you manage subcontractors?" Most ADU projects involve plumbers, electricians, roofers, etc. You want to know that the general contractor has a good working relationship with their subs and manages their schedules effectively.

Decoding the Quote: What to Look For

Getting a quote isn't just about the bottom line. It's about understanding what you're getting for your money. A good quote should be detailed, not just a single number.

  • Detailed Breakdown: Look for an itemized list of costs. This should include materials, labor, permits, site preparation, foundation, framing, plumbing, electrical, HVAC, finishes (flooring, cabinets, paint), and anything else specific to your project. If it's just a lump sum, walk away.
  • Clear Inclusions and Exclusions: What's included? What's not? For example, does it include landscaping or just rough grading? Does it cover all utility hookups or just bringing them to the property line? Make sure there are no ambiguities.
  • Payment Schedule: A legitimate contractor won't ask for 50% or more upfront. Typically, you'll see an initial deposit (often 10-20%), then progress payments tied to specific milestones (e.g., foundation complete, framing complete, rough-ins complete, etc.), with a final payment upon project completion and your satisfaction.
  • Allowances: For things like light fixtures, flooring, or cabinets, a contractor might include an "allowance." This is an estimated budget for those items. Make sure these allowances are realistic for the quality you expect. If you go over, you pay the difference.
  • Permit Costs: These should be clearly outlined. In Beaverton, getting through the permitting process can take a bit, and the fees aren't trivial. Make sure they're accounted for.

Red Flags You Can't Ignore

There are some signs that scream "trouble." Pay attention to your gut feeling, but also look for these concrete warnings:

  • High-Pressure Sales Tactics: "Sign today or lose this deal!" Good contractors are busy and don't need to pressure you.
  • Cash-Only Requests: This is a huge red flag. It often means they're trying to avoid taxes or operate outside the law.
  • No Written Contract: Never, ever proceed without a detailed, written contract. Verbal agreements are worthless when things go south.
  • Unusually Low Bid: If one bid is significantly lower than all the others, be very wary. They might be cutting corners, using cheap materials, or planning to hit you with a ton of change orders later.
  • Lack of References or Poor References: If they can't provide references, or the references you call sound hesitant, that's a problem.
  • Requests for Large Upfront Payments: As I mentioned, a huge deposit is a no-go.
  • Contractor Shows Up in an Unmarked Vehicle with No Business Info: Professional contractors usually have branded vehicles or at least some indication of their business.
  • Can't Answer Your Questions Clearly: If they're vague or evasive when you ask about their process, timeline, or costs, that's a sign they might not be as experienced or transparent as you need.

How to Verify They're Legitimate

Before you sign anything, do your homework. It takes a little time, but it's worth it for peace of mind.

  • Check Their CCB License: Go to the Oregon Construction Contractors Board website (oregon.gov/ccb). You can search by license number or business name. Make sure their license is active, and check for any disciplinary actions or complaints. This is probably the most important step.
  • Verify Insurance: Ask for a certificate of insurance directly from their insurance carrier, not just a copy from the contractor. This confirms their coverage is active.
  • Look Up Their Business Online: A quick Google search can tell you a lot. Do they have a website? Do they have reviews on Google, Yelp, or other platforms? While not all reviews are perfect, a pattern of extremely negative reviews or no online presence at all can be concerning.
  • Check with the Better Business Bureau (BBB): While not foolproof, the BBB can sometimes show if there's a pattern of unresolved complaints.
  • Ask for Proof of Workers' Comp: If they have employees, they need workers' compensation insurance. You don't want to be liable if one of their workers gets hurt on your property.
  • Visit a Current Job Site (if possible and with permission): If a contractor offers or agrees to let you see a project they're currently working on, take them up on it. See how organized the site is, how the crew works, and talk to the homeowner if they're around.

Building an ADU is a big investment, especially with the specific soil conditions we often see around Beaverton, like the heavy clay that can impact foundation work. You want a contractor who understands these local nuances and has a solid reputation. Don't rush the hiring process. Take your time, ask the tough questions, and trust your instincts. Here at Coastal ADU, we believe in transparency and doing things right the first time. Good luck with your project!
