ADU Permit Process Made Simple

Building an Accessory Dwelling Unit (ADU) can transform your property’s value and flexibility — but understanding the permit process is essential before you begin.
As a California-licensed architect, Backyard Project helps homeowners move from idea to city-approved plans with clarity and confidence.

Step 1 – Site Feasibility & Zoning Review

Every ADU project begins with understanding what’s buildable on your lot.
Cities have different rules about setbacks, height, parking, and size limits.
A professional zoning check or our $99 ADU Fit Report shows exactly where you can build, how large it can be, and what type of ADU your city allows.

Step 2 – Design Development

Once the site potential is confirmed, design can begin.
This stage includes floor plans, elevations, and coordination with structural and energy consultants.
We balance aesthetics, cost, and permit requirements — turning your idea into a functional, code-compliant design.

Step 3 – Permit-Ready Construction Documents

Cities require a full set of stamped plans for review: architectural drawings, structural calculations, Title-24 energy forms, and site plans.
Our team prepares complete, permit-ready plans that help minimize correction cycles and speed up approval.

Step 4 – City Review & Approval

Most city reviews take two to four months depending on workload.
Plan-check corrections are common — but with a licensed architect coordinating responses, the process stays on track and predictable.

Step 5 – Building Your ADU

Once approved, you can work directly with your preferred builder or ask us to connect you with trusted ADU contractors in your area.
We recommend getting multiple quotes and comparing scope, timeline, and warranty before construction.
