Local Intelligence
What Seguin Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Seguin — Permits Department will not accept a permit application without them. Seguin's current ADU size cap is 900 sq ft — within the typical range for most floor plan configurations.
Seguin currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
Homeowners in Seguin who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,085/month.
Permit Process & Fees
Permits Department permit fees for this project type typically range from $1,943 to $2,355 depending on project valuation and scope.
Floor plans submitted to Permits 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 Permits Department ↗Construction Cost Context
Seguin's adu / renovation construction costs run $280–$420 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 Seguin
Older neighborhoods near downtown Seguin often still run on shared or undersized water lines from the 1950s, so the Permits Department will frequently require a separate water tap and meter for the ADU even if your existing line technically has capacity — that's a City Water Utility fee that can catch homeowners off guard since it's billed separately from the building permit. Because Guadalupe County still has properties on septic outside the city sewer grid, if your lot isn't tied into Seguin's sewer system you'll also need a County health department review of your septic system's capacity before the city will sign off, which can add weeks if the existing system was sized only for the main house. Also, since STRs aren't allowed here, be prepared for the reviewer to ask upfront how the unit will be used — framing it as a mother-in-law suite or family unit on the application tends to move faster than anything hinting at rental use.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that missing timeline and cost data isn't unusual for Seguin—these figures are typically state-level estimates rather than verified local numbers, so I'd strongly advise getting actual quotes from a couple of Seguin contractors and calling the Permits Department directly before penciling in a budget or schedule. With HOA coverage sitting at nearly half the market here, I've also seen plenty of projects stall not on the permit side but on architectural review committees, so don't overlook that step just because it's not reflected in this data."
Market Context
Seguin has a median home value of $260,000. Comparable renovation projects in this market typically add 20% to resale value.

Common Questions
Seguin Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Seguin? +
You need accurate floor plans for: permit applications (required by Seguin'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 Seguin? +
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. Seguin'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 Seguin? +
Our floor plan drafting packages for Seguin 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 Seguin 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 Seguin 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 Seguin 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 Seguin? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Seguin. 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 Seguin? +
In Seguin, where median home values are around $260,000, 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 Seguin? +
Yes — Seguin'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 Seguin? +
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 Seguin homes built before the 1990s.
