How We Work

Our process keeps you informed at every step. We start with your vision, manage permits, then build with precision and care.

Plan and Assess Your Space

We begin by understanding your property and Riverside zoning requirements. Most sites in Riverside allow ADUs on single-family lots up to a certain square footage.

This phase covers site review, utility line mapping, and preliminary design concepts. Clear planning prevents costly revisions later.

Secure Local Permits

Riverside's permitting process demands detailed drawings, parking plans, and setback compliance. We prepare all submissions and manage back-and-forth with city planners.

Our experience with Riverside code speeds approval. You get clear documentation and peace of mind before breaking ground.

Build to Code and Your Standards

Construction begins with a solid foundation and framing. We follow all Riverside building code, energy standards, and accessibility rules.

Daily communication keeps you aligned with progress. You'll see the structure rise and systems go in on schedule.

Inspect and Hand Over

Final inspections ensure every detail meets code. We coordinate city inspectors, resolve any punch-list items, and deliver you a complete, functional unit.

You receive all permits, warranties, and as-built documentation. Your ADU is ready to use or rent.

Why It Matters

An ADU unlocks property value and housing flexibility. Building it right protects your investment and ensures legal compliance.

Maximize Property Value

A properly built ADU increases property value and rental income potential. Riverside's strong housing demand makes ADUs an attractive investment.

A permitted, code-compliant ADU appraises higher and qualifies for financing. Unpermitted units risk fines and resale complications.

We ensure full compliance so you can confidently rent, sell, or refinance your property.
