Aaron's take

ADUs are a newer search than most home improvement work, and many homeowners are still learning what they are. "ADU" and "accessory dwelling unit" each get around 90,500 searches a month in the US, but "ADU builder" only about 9,900. Most people are still researching rules, costs and options, such as detached units, garage conversions and prefab ADUs, before they look for a builder.

The ADU builders that win online answer those early questions well: what is allowed locally, what an ADU costs, how long it takes and how permits work. I found no ADU category on Google Business Profile, so builders rely on Home builder or General contractor categories and clear descriptions.

Your website

Pages your website needs

In the order I would build them. Each page targets one group of searches.

  1. What is an ADU page

    Many homeowners are still learning. A clear guide brings them in early.

  2. Local ADU rules page

    Rules vary by city. Explain what is allowed where you build.

  3. ADU cost page

    Cost is the biggest question. Explain ranges and what drives them.

  4. A page for each ADU type

    Detached units, garage conversions and in-law suites each have their own searches.

  5. Process and permits page

    Explain the steps from design to move-in, and how long each takes.

  6. Project gallery

    Finished ADUs, with size and type, help homeowners picture their own.

What to get right

  • I found no ADU category in Google's listings data. ADU builders I found used Home builder or Custom home builder, often with General contractor.
  • Say "ADU" and "accessory dwelling unit" clearly in your description and services.
  • Add Architecture firm only if you have licensed architects on staff.
  • Upload photos of finished ADUs, inside and out.

Reviews

Reviews that matter for ADU and addition builders

Where reviews count

  • Google
  • Houzz
  • Yelp
  • Nextdoor
  • Ask every customer, not only the happy ones, right after the job is done.
  • Send one short message with a direct link, so leaving a review takes a single tap.
  • Reply to every review, good or bad, calmly and specifically.
  • Never pay for reviews or offer anything in return. It breaks Google's rules.

Ads and SEO

Local Services Ads, Google Ads and SEO

ADU And Addition Builders can't use Local Services Ads, so paid search means Google Ads. Ads bring leads within days but stop the moment you stop paying. SEO takes months to build, then keeps working. Most businesses run ads for the most valuable searches while SEO grows, then shift budget as organic rankings take over.

For context, Google search ads in the Home & Home Improvement category average $90.92 per lead (LocaliQ, 2026). That is a search ads benchmark, not a Local Services Ads lead price.

Mistakes

Mistakes ADU and addition builders make

  1. Assuming people know what an ADU is

    Many are still learning. Start with the basics.

  2. Ignoring local rules

    Rules vary by city. Explaining them shows real local knowledge.

  3. No cost guidance

    Cost is the biggest question. Ranges help homeowners decide.

  4. Vague profile

    With no ADU category, your description must say exactly what you build.

FAQ

Adu Builder SEO questions

How do homeowners search for ADU builders?

Mostly by researching first. "ADU" and "accessory dwelling unit" each get about 90,500 searches a month in the US, but "ADU builder" only about 9,900. Guides on what an ADU is, local rules and costs bring homeowners in before they start comparing builders.

Can ADU builders use Local Services Ads?

ADUs are not a separate Local Services Ads category on Google's US list, so most ADU builders use regular Google Ads. SEO matters even more as a result, especially content that answers early questions about rules, costs and timelines. Reviews that mention the type of ADU you built also help your profile match more searches.

What Google Business Profile category should an ADU builder use?

I found no ADU category in Google's listings data. The ADU builders I found used Home builder or Custom home builder, often with General contractor. Say "ADU" and "accessory dwelling unit" clearly in your description and services, so Google understands what you build.

Should ADU builders explain local rules?

Yes. Rules on size, setbacks, parking and permits vary by city, and homeowners search for them. A clear page on what is allowed where you build shows real local knowledge, and brings in homeowners at the start of their research.

How much does SEO cost for an ADU builder?

That comes down to three things: the competition where you work, how many services and cities you want to target, and the state of your website today. For most ADU builders, a monthly arrangement works best, because local rankings build over time. I start by looking at your site and your rivals, then send a fixed quote.
