Local Intelligence
What Phoenix Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Phoenix — Planning and Development Department will not accept a permit application without them. Phoenix's current ADU size cap is 3,000 sq ft — generous enough to accommodate most project types.
Phoenix does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Phoenix who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,239/month.
Permit Process & Fees
Planning and Development Department permit fees for this project type typically range from $1,800 to $7,000 depending on project valuation and scope. Plan check runs approximately 5 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Planning and Development Department as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Planning and Development Department ↗Construction Cost Context
Phoenix's adu / renovation construction costs run $200–$300 per square foot — a moderate range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Phoenix
One thing that catches people off guard: Phoenix requires a separate electrical panel upgrade review if your existing service is under 200 amps, since most ADUs plus existing home loads push past what an old 100-amp panel can handle — and APS scheduling for the utility upgrade can take longer than the actual ADU permit review. Also, if your lot is on a septic system in unincorporated Maricopa County pockets, the Environmental Services division requires a separate septic capacity verification before Planning and Development will even accept your ADU application, which can add several weeks nobody budgets for.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that $250/sqft figure and 5-week plan check are Phoenix state-level estimates, not gospel—I'd get quotes from two or three local contractors and call the Planning and Development Department directly before you bank on those numbers. And even in the best case, 5 weeks assumes a clean, correction-free drawing set; I've seen straightforward projects stretch to 10-12 weeks once you factor in a single round of corrections."
Market Context
Phoenix has a median home value of $349,000. Comparable renovation projects in this market typically add 21.0% to resale value.
Neighborhoods in Phoenix with the strongest renovation and resale value potential include Encanto-Palmcroft, Arcadia, North Central Phoenix, Sunnyslope, Laveen. Historic large lots near downtown and hospitals with active demand make this area ideal for detached ADUs.
Permit Process
Permit applications are reviewed by the Planning and Development Department, with a plan check timeline of approximately 5 weeks. Permit fees in Phoenix range from $1,800 to $7,000 depending on project scope. Design review: Yes - in historic districts only.
Phoenix falls within Seismic Design Category Seismic Design Category A (very low) per ASCE 7 — general/default for Phoenix/Maricopa County; site-specific SDC must be confirmed using USGS/ASCE 7 hazard tools, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Phoenix Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Phoenix? +
You need accurate floor plans for: permit applications (required by Phoenix's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Phoenix? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Phoenix's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Phoenix? +
Our floor plan drafting packages for Phoenix start at $997 for a standard residential home. This includes measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my Phoenix home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Phoenix neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Phoenix building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Phoenix? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Phoenix. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Phoenix? +
In Phoenix, where median home values are around $349,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Phoenix? +
Yes — Phoenix's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Phoenix? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Phoenix homes built before the 1990s.
