Local Intelligence
What Port Arthur Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Port Arthur — Development Services will not accept a permit application without them. Port Arthur's current ADU size cap is 900 sq ft — within the typical range for most floor plan configurations.
Port Arthur 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 Port Arthur who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,097/month.
Permit Process & Fees
Floor plans submitted to 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 Development Services ↗Construction Cost Context
Port Arthur's adu / renovation construction costs run $280–$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 Port Arthur
Because most of Port Arthur sits within the coastal overlay, your ADU plans need a Coastal Development Permit on top of the standard building permit — this typically adds several weeks of review since Development Services has to check flood venting, elevation certificates, and wind-load details before your project even gets to the regular plan check line. Given the city's low-lying drainage and older cast-iron sewer laterals in neighborhoods like Pear Ridge, many homeowners get hit with a surprise requirement to replace or line their sewer lateral before the city will approve a new water tap for the ADU. Because Jefferson County's flood maps changed after Harvey, your finished floor elevation may need to be higher than your existing house, which can quietly turn a simple slab-on-grade ADU into a raised pier-and-beam structure.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, both the timeline and cost-per-square-foot figures here look like unverified state-level estimates rather than true Port Arthur numbers, so I'd strongly recommend getting a couple of local contractor quotes and calling Development Services directly before budgeting or scheduling. What the data also doesn't show is that with the coastal overlay in play, your CDP review will almost certainly add weeks to whatever plan check timeline you're quoted — I've rarely seen that process move quickly, even with a clean drawing set."

Common Questions
Port Arthur Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Port Arthur? +
You need accurate floor plans for: permit applications (required by Port Arthur'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 Port Arthur? +
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. Port Arthur'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 Port Arthur? +
Our floor plan drafting packages for Port Arthur 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 Port Arthur 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 Port Arthur 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 Port Arthur 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 Port Arthur? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Port Arthur. 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 Port Arthur? +
In Port Arthur, where median home values are around $120,000, 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 Port Arthur? +
Yes — Port Arthur'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 Port Arthur? +
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 Port Arthur homes built before the 1990s.
