Residential
Permit-ready documentation for residential projects.
From single-family additions to ADU packages and whole-home remodels, CADTRI produces the complete drawing sets that residential contractors, architects, and property owners need to clear plan check.
Overview
Residential permit documentation requires precise coordination between design intent, local zoning rules, and jurisdiction-specific submittal standards. CADTRI prepares complete drawing packages for single-family homes, accessory dwelling units, garage conversions, room additions, pool and spa installations, and interior remodels. Every set is built to the applicable building department's checklist before a single sheet is drafted, so the package arrives at the counter ready for review, not revision.

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 rules, floor area ratios, and lot coverage limits. We calculate these constraints at intake to confirm feasibility before production begins, preventing corrections that would otherwise come back from the plan checker.
Title 24 Energy Code
California residential projects require a certified energy compliance package alongside the architectural set. We coordinate Title 24 documentation as part of every permit set so the submittal package is complete from day one.
ADU Regulations
State ADU law overrides many local restrictions, but the specific implementation varies by jurisdiction. Our ADU packages are pre-researched for the applicable city before drafting begins, covering setbacks, height limits, owner-occupancy requirements, and parking exemptions.
Plan Check Resubmittal
Residential plan checkers frequently issue corrections on initial submittal. Our correction response packages include clouded revisions, a formal response letter addressing every comment, and updated sheets organized for efficient re-review.
