Remodels & Additions
Remodel & Addition Plans in Arizona
Residential Design provides permit-ready plans for remodels, additions, garage conversions, carport enclosures, and layout changes where drawings are needed for city review. This service is focused on projects that affect the structure, layout, exterior, or permitted use of an existing home—not cosmetic-only upgrades.
What This Service Covers
Remodel plans for projects that require documentation
We are usually involved when a remodel needs plans for permitting, review, construction coordination, or clarification of existing conditions. The goal is to document what exists, define what is changing, and prepare drawings that help the project move forward.
Home Additions
Plan sets for expanding existing homes, adding rooms, extending living space, or tying new construction into the existing structure.
Wall Removals & Layout Changes
Drawings for remodels that change the floor plan, remove or modify walls, or require structural coordination and city review.
Garage & Carport Conversions
Permit drawings for converting or enclosing existing garage and carport areas into conditioned or usable space.
Existing Work & Permit Corrections
Documentation support for prior additions, enclosed patios, converted spaces, or other work that needs a clear path for review.
What's Included
Built around existing conditions and permit needs
Remodel and addition work is different from designing on a blank lot. Existing walls, roof conditions, foundations, utilities, prior modifications, and city records can all affect the plan set. Accurate documentation early helps reduce surprises later.
- Existing-condition review and as-built coordination
- Proposed floor plan and layout updates
- Permit-ready remodel and addition drawings
- Wall removal and layout-change documentation
- Garage and carport conversion planning
- Coordination points for structural engineering when needed
- Site and zoning awareness for additions
- Plan review support when corrections are issued
Our Design Process
A clear, collaborative approach from initial concept to construction-ready documents.
Initial Fit & Project Review
We start by reviewing the property, project type, goals, and any existing information to understand the scope and whether the project is a good fit.
Existing Conditions & Site Information
If needed, we work from prior plans, site information, photos, or measured as-built drawings so the design starts from accurate existing conditions.
Design & Layout Development
Floor plans and layout ideas are developed around the lot, the project goals, and how the space actually needs to function.
Permit Plans & Revisions
Once the design is dialed in, the drawing set is prepared for permitting and updated as needed to respond to plan review comments.
Remodel & Addition FAQ
Frequently Asked Questions
Do you design cosmetic remodels?
Not typically. This service is focused on remodels and additions where plans are needed because the project affects the structure, layout, exterior, use of space, or city permit requirements. Cosmetic-only kitchen, bath, cabinet, countertop, or finish updates are usually outside the scope of what we provide.
When do remodels usually need plans?
Plans are commonly needed when walls are moved or removed, rooms are added, garages or carports are converted, exterior openings change, structural work is involved, or the city requires drawings to review the scope of work.
Do you document existing conditions first?
Often, yes. Remodels and additions usually depend on accurate existing information. When prior plans are unavailable or unreliable, measured as-built drawings can help establish what exists before proposed work is designed.
Do you provide structural engineering?
Structural engineering is typically handled by a licensed engineer when required. We prepare the architectural/residential design drawings and coordinate the plan set so engineering information can be incorporated when needed.
