Local Intelligence
What Hillsboro Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Hillsboro — Community Development Department will not accept a permit application without them. Hillsboro's current ADU size cap is 900 sq ft — within the typical range for most floor plan configurations.
Hillsboro 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 Hillsboro who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,800/month.
Permit Process & Fees
Community Development Department permit fees for this project type typically range from $750 to $8,000 depending on project valuation and scope. Plan check runs approximately 7 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Community 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 Community Development Department ↗Construction Cost Context
Hillsboro's adu / renovation construction costs run $200–$490 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 Hillsboro
Permit reviews generally take roughly 60 to 90 days in Hillsboro, and while state law prohibits requiring off-street parking for ADUs, it's always wise to confirm specific requirements with the planning department before investing in full permit drawings.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience working Hillsboro permits, that $280/sqft and 7-week timeline are Hillsboro state-level estimates, not local quotes, so I'd call the Community Development Department directly and get at least two local contractor bids before budgeting; I've also seen plenty of 7-week projections stretch to 10-12 weeks once corrections come back on an incomplete drawing set."

Common Questions
Hillsboro Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Hillsboro? +
You need accurate floor plans for: permit applications (required by Hillsboro'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 Hillsboro? +
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. Hillsboro'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 Hillsboro? +
Our floor plan drafting packages for Hillsboro cover 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 comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Hillsboro 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 Hillsboro 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 Hillsboro 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 Hillsboro? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Hillsboro. 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 Hillsboro? +
In Hillsboro, where median home values are around $508,000, 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 Hillsboro? +
Yes — Hillsboro'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 Hillsboro? +
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 Hillsboro homes built before the 1990s.
