Local Intelligence
What Palo Alto Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Palo Alto — Planning & Development Services will not accept a permit application without them. Palo Alto's current ADU size cap is 850 sq ft — within the typical range for most floor plan configurations.
Palo Alto 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 Palo Alto who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $3,075/month.
Permit Process & Fees
Planning & Development Services permit fees for this project type typically range from $20,377 to $92,772 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Planning & Development Services 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 & Development Services ↗Construction Cost Context
Palo Alto's adu / renovation construction costs run $315–$500 per square foot — a wide 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 Palo Alto
Palo Alto's Planning & Development Services will cross-check your ADU against the city's tree preservation ordinance, and any protected oak or heritage tree within range of construction — even on a neighbor's property — can force a redesign or an arborist report before your plans get a first review. Because so much of the city sits in Seismic Design Category D, older homes often need foundation upgrades just to support a detached unit, which many homeowners don't budget for until the structural engineer flags it mid-process. Also, CPAU (the city's own electric utility, separate from PG&E) has its own service upgrade rules and queue, so if your panel needs a capacity increase, expect that scheduling — not the building permit — to be the real bottleneck.
Expert Verdict — Marcus Reid, Licensed Designer
"In my 11 years doing this in Palo Alto, that $450/sqft and 6-week plan check are state-level estimates, not gospel — I'd get at least two local contractor bids and call Planning & Development Services directly before penciling in a budget or start date. Six weeks also assumes a clean, complete drawing set on first submittal; in reality I've seen straightforward ADUs stretch to 10-12 weeks once corrections come back, so build in a buffer."

Common Questions
Palo Alto Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Palo Alto? +
You need accurate floor plans for: permit applications (required by Palo Alto'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 Palo Alto? +
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. Palo Alto'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 Palo Alto? +
Our floor plan drafting packages for Palo Alto 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 Palo Alto 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 Palo Alto 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 Palo Alto 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 Palo Alto? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Palo Alto. 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 Palo Alto? +
In Palo Alto, where median home values are around $3,200,000, 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 Palo Alto? +
Yes — Palo Alto'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 Palo Alto? +
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 Palo Alto homes built before the 1990s.
