Nucave Construction: A 100-Page Custom Website Built to Sell ADUs

Nucave Construction has been building across San Diego County since 2016 - CSLB licensed, with 100+ projects delivered. The projects, photos, and story were all there on their old website - but the aging build was hard to update and sold the work short, and it gave homeowners no way to explore what an ADU project would actually involve or cost.

An ADU is one of the biggest purchases a homeowner ever makes. Buyers research for months - costs, regulations, feasibility, financing - before they ever call a builder. The old site couldn't answer the biggest of those questions, what a project would cost and whether a property was even a fit, so that research happened on other people's websites.

There was also a real risk to manage: the old site had rankings Google took years to assign. Replace a website carelessly and those rankings vanish. The move to the new site had to be handled as carefully as the new build itself.

Built a custom website of roughly 100 pages, designed page by page around how homeowners actually research an ADU project.

Created an interactive ADU Cost Planner: a 5-step tool that gives homeowners an instant estimate range and a project readiness score, and sends Nucave the lead right away.

Added free homeowner lookup tools, including a sewer lateral lookup and a fire zone lookup, so the site answers questions homeowners can't easily answer anywhere else.

Wrote 7 city-by-city ADU regulation guides in plain English, turning county-level legal complexity into pages a homeowner can actually use - and search engines can rank.

Rebuilt 8 project pages with organized photo galleries and job-site video, with video also featured on the service pages.

Set up lead emails that arrive organized: every inquiry lands in Nucave's inbox laid out like an intake sheet, so follow-up calls start informed.

Migrated the blog preserving the owner's voice, plus floor plans, testimonials, and financing pages - nothing the old site did well was lost.

Handled the switch from the old site to the new one with care at launch, to protect the Google rankings the old site had spent years earning.

The site launched August 30, 2026 at nucave.com. PageSpeed Insights after launch: 87 performance on mobile, 96 accessibility, 100 best practices, and 100 SEO - the report is one click away at the top of this page.

Independent Semrush audits tell the before-and-after story: drag the comparison further down this page to see both audits side by side. The old site: 78% site health, 74 crawl errors, 271 warnings. The new site at launch: 94% site health - above the 92% average Semrush reports for the web's top-10% websites - with errors down to 1 and 100% scores for HTTPS, site performance, and markup.

AI Search Health rose from 87% to 97%, with every major AI crawler able to read the site - built for the era where buyers ask AI assistants for builder recommendations.

The entire build was delivered by a small team working directly with the owner - no account managers, no handoffs, and nothing lost between feedback and fixes.

The first SEO numbers since the switch are in, straight from Google Search Console. The Page indexing report counts 109+ indexed pages, and its chart steps up sharply right after the new site went live in late August: the pages built to be found are being found.

AI visibility climbed after the launch too. In the Generative AI features report, nucave.com recorded 1.47K+ impressions inside Google's AI features across 78 pages over three months. That window includes the old site's final weeks, and the daily line mostly stayed low through the summer; it turns upward after the late August launch and stays well above its summer level into September.

The engagement continues as a monthly SEO retainer: new content, more city guides, and a close watch on the site's Google rankings after the move. The Search Console reports above are the first post-launch read; a fuller SEO update follows once more data is in.
