ADU Builders San Diego (2026)

How to pick the right San Diego ADU builder, what to ask, and how to avoid the costly mistakes most homeowners make. Plus — what makes us different.

What to Look for in a San Diego ADU Builder

ADU specialization. Builders who do ADUs full-time know San Diego code, plan check pitfalls, and how to keep costs under control.
Permit-first design. A builder should design to code from day one — not redesign mid-project.
Transparent pricing. Detailed written estimates, clear scope of work, and a fair change-order policy.
Local experience. Recent projects in San Diego County and references you can call.
End-to-end service. One team for design, permits, and construction — fewer gaps, fewer finger-pointing problems.
Investment mindset. A builder who can pencil out rental income and ROI alongside the build.

Verbal estimates with no written breakdown
Pressure to sign before plans are complete
Refusal to provide references or recent projects
Bids significantly below market (often signals cut corners or change-order traps)
No clear permit pathway or timeline
Unwillingness to discuss ROI or rental income

We're a San Diego-focused ADU team. We design, permit, and build — start to finish — and we treat every project like the investment it is.
