Building permit drawings for your home project

Move from an idea to a clear drawing package. HomeCat helps you plan the project, document the site, and produce the drawings a permit reviewer and builder need to understand the work.

  • Plans and elevations
  • Construction details
  • One coordinated package

Drawings that explain what you are building

A permit package has to do more than show a finished design. It needs to communicate size, location, structure, materials, and the relationship between the proposed work and the existing property.

HomeCat brings those views together so the site plan, floor or framing plan, elevations, and details describe the same project. HomeCat checks the property's zoning automatically and flags the permit or professional-review items that apply to the work.

How it works

  1. 01

    Sign in and add the project

    Enter the project type, property, approximate size, budget, and the features you want HomeCat to plan.

  2. 02

    Review the coordinated design

    HomeCat checks zoning and coordinates the site, plans, elevations, structure, and project details in one model.

  3. 03

    Save and export the package

    Save the project and export coordinated drawings for permits, contractor pricing, material planning, and construction.

Project measurements and costs

HomeCat keeps the project dimensions connected to material quantities and cost inputs as the plan changes.

Measured project details

  • Complete Building Envelope

    HomeCat captures the footprint, floor elevations, wall heights, roof slopes, and overall building height used across the permit set.

  • Openings And Circulation

    HomeCat measures every door, window, stair, landing, hallway, and exit path so plans, elevations, and sections stay coordinated.

  • Site And Structure

    HomeCat records setbacks, foundation extents, floor spans, bearing lines, and roof geometry needed to position and describe the work.

Material and cost inputs

  • Structural Material Quantities

    Coordinated foundation, floor, wall, and roof geometry supports takeoffs for concrete, lumber, sheathing, connectors, and roofing.

  • Envelope And Openings

    Door and window schedules combine with wall and roof areas to organize pricing for assemblies, finishes, flashing, and insulation.

  • Permit Scope Clarity

    A consistent drawing package exposes the full construction scope so estimators can price the same dimensions, details, and quantities.

What homeowners usually ask

Does HomeCat check my property's zoning requirements?

Yes. HomeCat automatically checks the property's zoning requirements and uses them to guide the project. It also flags permit or professional-review items that still need attention.

What drawings are usually needed for a residential building permit?

The package often includes a site plan, plan views, elevations, sections, and project-specific structural or construction details. HomeCat selects the applicable sheets from the project, property, zoning check, and permit scope.

Are building permit drawings the same as architectural renderings?

No. A rendering communicates appearance. Permit drawings communicate measurable information such as dimensions, location, assemblies, structure, height, and code-related details.

Can HomeCat update the drawings after permit comments?

Yes. Reviewer comments can be incorporated into the coordinated plans so the site plan, plan views, elevations, and construction details stay aligned for resubmission.

Can I use the same drawings to get contractor quotes?

Yes. A clear, coordinated scope helps contractors price the same project and reduces the assumptions hidden inside each quote.
