Permit drawings translate the existing property and proposed work into a coordinated set of plans and details that can be reviewed before construction begins.
A complete submission may need existing and proposed layouts, construction assemblies, structural details, plumbing or mechanical information, site information and designer documentation. The required scope depends on the project.
Permit Drawing Components
The drawings should be accurate enough to guide both municipal review and field construction.
Existing Conditions
Document current rooms, walls, openings, stairs, structure and building systems.
Proposed Floor Plan
Show rooms, dimensions, fixtures, doors, windows and unit boundaries.
Construction Details
Describe walls, insulation, fire separation, ceilings and service penetrations.
Exterior Work
Show entrances, windows, wells, drainage, guards and property relationships.
Structural Information
Provide support, lintel, framing or engineering details where required.
Designer Documentation
Include the applicable designer information and schedules for the project.
From Site Measure to Submission
- Define the projectClarify the current use, proposed use and complete construction scope.
- Collect property informationGather surveys, builder plans, previous permits and relevant notices.
- Measure existing conditionsRecord the basement and affected areas accurately.
- Develop the designCoordinate layout, structure, services and required assemblies.
- Review the drawing setResolve conflicts and confirm owner decisions before submission.
- Respond to review commentsRevise or supplement the application as required.
Information to Gather Before Design
Better source information reduces assumptions and revisions.
- Legal property survey
- Previous building permit drawings
- Current basement measurements
- Photos of mechanical and electrical equipment
- Existing inspection notices or orders
- Desired rooms, unit use and future plans
What Shapes the Project Scope and Cost?
A responsible estimate follows the property assessment and proposed scope. Important cost drivers include:
- Project type and number of affected floors
- Accuracy and availability of existing records
- Exterior or structural work
- Engineering involvement
- Number of revisions caused by owner changes
- Complexity of existing legalization work
Use the correct professional title.
A qualified designer, BCIN designer, professional engineer and architect have different scopes and credentials. The person preparing or reviewing documents should be identified accurately.
Frequently Asked Questions
Can I submit hand-drawn plans?
Submission standards and designer requirements depend on the project. Professional drawings are generally valuable for coordinated legal basement work.
Do drawings include construction pricing?
Drawings define scope but do not automatically include a contractor quote. The approved design supports more meaningful pricing.
What if construction needs to change from the plans?
Changes that affect the approved design may require revised drawings or approval before proceeding.
Can drawings legalize work that is already finished?
Drawings document the existing and proposed condition, but concealed construction and deficiencies still need to follow the required inspection and correction path.
