ADU Permit Package

Building an ADU means navigating a maze of zoning rules, setback requirements, height limits, owner-occupancy rules, impact fees, and utility connections — all of which vary by city and county. Many homeowners get stuck at the planning department, lose months to revisions, or have applications rejected for missing engineering stamps or incomplete site plans. ADU regulations also change frequently, and many jurisdictions added streamlined ADU approval processes that most people don't know how to use.

QuiPermit handles the entire ADU permit package from start to finish. Our licensed engineers prepare the construction documents, sealed structural plans, site plan, energy compliance forms, and all jurisdiction-specific ADU paperwork. We know which cities offer streamlined ministerial ADU approval and we package your application to qualify. We coordinate with local engineering partners who understand your specific ADU ordinance and submit, track, and expedite your permit through approval.

1) Free consultation — we review your lot, zoning, and ADU goals. 2) Design and engineering — we prepare construction documents and sealed structural plans tailored to your local ADU ordinance. 3) ADU-specific paperwork — setback analysis, owner-occupancy affidavit, utility plan, and impact fee forms. 4) Submission and expediting — we submit to your building department, respond to corrections, and secure your permit approval.

What's Typically Required

Typical ADU permit packages require: site plan showing setbacks, floor plans, elevations, structural engineering plans and calculations (sealed), foundation plan, energy compliance (Title 24 in CA or local equivalent), electrical/plumbing/mechanical plans, and ADU-specific forms (owner-occupancy, exemption affidavits where applicable).
