From single-family additions and ADU permit plans to garage conversions and whole-home remodels, CADTRI produces complete residential permit drawings that help contractors, architects, and property owners move through plan check with fewer delays.

Overview

Residential construction drafting requires careful coordination between design intent, zoning requirements, and jurisdiction-specific permit standards. CADTRI prepares complete residential construction documents for single-family homes, accessory dwelling units, garage conversions, room additions, pool and spa installations, and interior remodeling projects.

Common Challenges

Where residential projects stall.

These are the documentation and permitting issues that consistently delay residential projects. CADTRI addresses each one at the production stage, before the set reaches the plan checker.

Setback and Zoning Compliance

Every city and county applies different setback requirements, lot coverage limits, and floor area standards. We review zoning requirements during intake to confirm feasibility before production starts, helping avoid costly revisions during permit approval and residential permit coordination.

Title 24 Energy Code

California residential projects require certified Title 24 documentation alongside the architectural residential drawings. We coordinate energy compliance as part of the full construction drawing package so the permit submission is complete from day one.

ADU Regulations

California ADU regulations override many local restrictions, but every jurisdiction applies them differently. Our ADU permit plans are researched for the applicable city before drafting begins, including setbacks, parking exemptions, height limitations, and owner occupancy requirements.

Plan Check Resubmittal

Residential permit drawings frequently receive correction comments during the initial review cycle. Our response packages include clouded revisions, updated residential construction documents, and formal response letters organized for efficient re-review and faster permit workflow completion.
