What Pasadena Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Pasadena — Permit Department will not accept a permit application without them. Pasadena's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Pasadena 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 Pasadena who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $917/month.
Permit Process & Fees
Permit Department permit fees for this project type typically range from $415 to $565 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 Permit 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 Permit Department ↗Construction Cost Context
Pasadena's adu / renovation construction costs run $200–$350 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 Pasadena
Since Pasadena, Texas sits within Harris County but runs its own Permit Department, homeowners often get tripped up when the city's plan review requirements don't match the county's floodplain rules — and much of Pasadena falls in or near a FEMA-mapped flood zone tied to Vince Bayou and Berry Bayou drainage. That means an elevation certificate is often required before the Permit Department will even log your ADU application, adding real time if your surveyor isn't familiar with the city's specific bayou-adjacent parcels. On top of that, older sections of Pasadena still run on shared or undersized sewer laterals, so the city frequently requires a sewer tap inspection and sometimes a line upsizing before final approval — a cost and delay that catches most homeowners off guard.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Pasadena plan check, that $250/sqft and 6-week timeline read as state-level estimates rather than street-level reality — I've seen well-drawn sets clear in that window, but with 57% of properties under an HOA layering on architectural review, 8-12 weeks is more typical once you account for corrections and HOA sign-off. I'd call Pasadena's Permit Center directly and get a couple of local contractor bids before penciling in a start date, since both figures can shift once your specific lot and HOA are in the mix."

Common Questions
Pasadena Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Pasadena? +
You need accurate floor plans for: permit applications (required by Pasadena'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 Pasadena? +
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. Pasadena'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 Pasadena? +
Our floor plan drafting packages for Pasadena 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 Pasadena 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 Pasadena 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 Pasadena 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 Pasadena? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Pasadena. 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 Pasadena? +
In Pasadena, where median home values are around $165,000, 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 Pasadena? +
Yes — Pasadena'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 Pasadena? +
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 Pasadena homes built before the 1990s.
