As-Built Drawings in Arizona
Residential Design provides measured as-built drawings for existing homes when accurate documentation is needed before remodels, additions, or permit review. These drawings establish what actually exists so projects can move forward with clarity.
Next Step
Start by clarifying what needs to be documented
As-built work is most useful when the purpose is clear: remodel planning, missing records, permit corrections, or documenting what currently exists.
Good fit projects
- Homes with missing, outdated, or unreliable plans
- Remodels and additions that need an existing-condition base
- Permit corrections where prior work needs documentation
- Existing work that a city, county, buyer, or contractor needs clarified
Helpful to send first
- Property address and reason the drawings are needed
- Photos of the areas that need to be documented
- Old plans, permit records, or city comments if available
- Any deadline, submittal need, or next design step

Remodel Planning Support
Accurate existing-condition drawings used as a base before designing additions, layout changes, or structural work.
Permit Corrections
As-built documentation for prior work, enclosed spaces, or additions that need clarification during review.
Pre-Design Verification
Establishing what exists before planning begins to reduce surprises during design and permitting.

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.

As-Built FAQ
Frequently Asked Questions
What are as-built drawings?
As-built drawings document what currently exists. They are created by measuring the home and producing floor plans that reflect the actual layout, rather than relying on outdated or missing plans.
When do I need as-built drawings?
They are commonly needed before remodels, additions, or permit corrections, especially when original plans are not available or do not reflect current conditions.
Do cities require as-built drawings?
Some projects require existing-condition documentation to clarify what is currently built. This is especially common when prior work was done without permits or when changes are being reviewed.
Can as-built drawings be used for future design?
Yes. As-built drawings are often the starting point for remodels, additions, and other design work because they establish a reliable base to work from.
