Pasadena permitting at a glance

ADUs are permitted on most single-family and many multifamily parcels, though approval is site-specific. Key factors include setbacks, height limits, lot coverage, utility connections, and required parking. Properties in historic districts or neighborhood overlay zones may involve additional steps. Our feasibility review identifies these considerations early and outlines the clearest path to approval. (This is general information; final eligibility depends on your parcel and current city regulations.)

What the process looks like

  1. Assessing Feasibility & Parcel Fit – We start by reviewing your parcel for slope, access, utilities, and septic capacity. Then we recommend the best-fit prefab ADU model along with an order-of-magnitude budget.

  2. Design Choices & Scope Planning – Choose finishes and design options while we document site-work requirements, including foundation type, trenching, retaining, and drainage.

  3. Permitting & Regulatory Approvals – Our team prepares a permit-ready package and coordinates with the city/county, including any Coastal or fire authority reviews.

  4. Site Work & Installation – We manage grading, foundation work, trenching, and delivery/assembly logistics—even for narrow or steep access roads—followed by interior finishes and inspections.

  5. Final Walkthrough & Handover – After construction, we conduct a final walkthrough and provide documentation and care guidelines for rental, guest, or family use.
