Local Intelligence
What San Angelo Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in San Angelo — Building Permits & Inspections will not accept a permit application without them. San Angelo's current ADU size cap is 899 sq ft — within the typical range for most floor plan configurations.
San Angelo 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 San Angelo who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $996/month.
Permit Process & Fees
Building Permits & Inspections permit fees for this project type typically range from $1,978 to $3,229 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 Building Permits & Inspections 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 Building Permits & Inspections ↗Construction Cost Context
San Angelo's adu / renovation construction costs run $182–$255 per square foot — a moderate 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 San Angelo
Many older neighborhoods near downtown and Fort Concho still run on undersized water lines and clay sewer laterals from decades ago, so San Angelo's Building Permits & Inspections office will often require a licensed plumber to verify the existing service line can handle a second unit before they'll sign off on your permit. This can mean digging up part of the yard to inspect or replace the lateral, adding real cost and a few weeks homeowners don't expect. Since Tom Green County groundwater can shift clay soils seasonally, inspectors also tend to scrutinize ADU foundation plans closely even though the area sits in low seismic risk Zone A, so don't assume a simple slab will sail through review without extra soil compaction details.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that $260/sqft and 6-week timeline are San Angelo state-level estimates rather than verified local figures, so I'd get a few contractor quotes and call Building Permits & Inspections directly before penciling in a budget or start date — and even at 6 weeks, I've seen first-time submittals with incomplete drawing sets stretch well past that once corrections come back. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
San Angelo Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in San Angelo? +
You need accurate floor plans for: permit applications (required by San Angelo'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 San Angelo? +
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. San Angelo'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 San Angelo? +
Our floor plan drafting packages for San Angelo 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 San Angelo 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 San Angelo 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 San Angelo 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 San Angelo? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in San Angelo. 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 San Angelo? +
In San Angelo, where median home values are around $160,000, 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 San Angelo? +
Yes — San Angelo'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 San Angelo? +
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 San Angelo homes built before the 1990s.
