What the reviewer needs to understand quickly
A strong permit set makes the project scope obvious before the reviewer starts checking individual dimensions and details. For this project type, the drawing package commonly needs to communicate:
- ADU placement, setbacks and lot coverage
- Relationship to the main dwelling
- Sleeping-room egress and exterior openings
- Foundation and framing scope
- Electrical, plumbing and HVAC coordination
Project image is an illustrative planning visual. Permit drawings are prepared from your actual property and project information.
An ADU permit set may include
Every plan is drawn for your actual lot from your survey or plat, with the details your reviewer checks first.
- Site plan and setbacks
- ADU floor plan
- Exterior elevations
- Roof plan
- Building sections
- Foundation plan
- Wall and roof framing
- Electrical plan
- Plumbing plan
- HVAC plan

How the permit set fits together
Not every project needs every discipline. We confirm the required scope first, then coordinate the sheets that apply.
Site plan
Lot placement, setbacks, access and utilities.
Architectural
Floor plan, elevations, roof and building sections.
Structural
Foundation, framing and connection details when required.
MEP
Electrical, plumbing and HVAC sheets when included.
What can change the permit scope
Two projects with the same name can require very different drawings. These are the conditions that most often change the amount of architectural, structural, MEP or site work involved.
Zoning + placement
Setbacks, lot coverage, access and the relationship between the ADU and primary dwelling can change the required site information.
Detached vs. conversion
A detached ADU usually needs a new foundation and exterior elevations; a garage conversion needs detailed existing-condition and infill information.
Utilities
Separate or shared utility arrangements can affect plumbing, electrical and site coordination.
Habitable-space requirements
Egress, ceiling height, light/ventilation and conditioned-space details can add architectural or MEP sheets.

Texas review factors that can change the scope
Rules change from city to city. These are examples from official city permit pages, and we check the rules for your address before drawing.
Requirements change. Always confirm current rules with your permit office before you build.
Common reasons reviewers ask for corrections
These are recurring review issues we account for when preparing the agreed drawing scope.
- Existing and proposed conditions are not clearly distinguished
- Dimensions, notes or project scope are incomplete
- Required site, architectural, structural or trade information is missing
- Drawing sheets do not coordinate with one another
- Local review comments are not addressed in the resubmittal

Start with the information you already have. We identify any missing measurements, records or design inputs before drafting proceeds.
- Property addressSo we can confirm the city, county or ETJ rules.
- Survey or recorded plat when availableA PDF or clear image is fine. If it is unavailable, we confirm what source information is needed before drafting.
- Project detailsWhat you are building, its size and where it goes on the lot.
- Photos or a sketchOptional, but they help us place the work accurately.

Questions about Texas adu permit plans
Straight answers to what Texas owners and contractors ask us most.
What drawings are needed for an ADU permit?
Commonly a site plan plus architectural, structural and MEP drawings, depending on the jurisdiction and project.
Can a garage be converted into an ADU?
Often, but zoning, parking, building code and utility requirements must be checked for the property.
Do ADUs need separate utilities?
Requirements vary by jurisdiction and utility provider.
Can you prepare a mirrored or alternate layout?
Yes, design variants can be coordinated when included in the scope.
Do you provide structural engineering?
Structural drawings and Texas PE review can be coordinated when required.
Can you prepare both the ADU site plan and building plans?
Yes. The agreed scope can combine the site plan with architectural, structural and MEP drawings when the jurisdiction requires them.
What if I do not have the original house plans?
We can often work from a survey or plat, field measurements, photos and other available records. We confirm what source information is needed before drafting.
Can the ADU share utilities with the main house?
Possibly. Utility requirements depend on the jurisdiction, service provider and project design, so the permit set should reflect the selected arrangement.
Can you revise an ADU plan after city comments?
Yes. Covered drafting comments can be incorporated, while added design or engineering scope is quoted separately when needed.
