Garage plans for permits and construction

Plan the footprint, vehicle and storage space, doors, roof, foundation, and position on the lot before construction starts. HomeCat turns those decisions into a coordinated garage drawing package.

  • Single or multi-bay layouts
  • Foundation and roof information
  • Site placement and setbacks

Resolve the garage before it reaches the job site

Detached garage plans have to coordinate the building and the property. The interior needs practical vehicle, storage, door, and circulation space, while the exterior has to fit local lot coverage, height, access, and setback rules.

A useful drawing set keeps the site plan, floor plan, elevations, foundation, and roof information aligned. That makes the permit review easier to follow and gives contractors a more consistent basis for pricing.

How it works

  1. 01

    Sign in and set the garage

    Enter the property, number of bays, vehicles, storage, workshop needs, doors, and preferred roof form.

  2. 02

    Fit the design to the property

    HomeCat checks zoning and coordinates access, setbacks, lot coverage, grading, utilities, and the house relationship.

  3. 03

    Save plans and quantities

    Save the design and export the site, floor, elevation, foundation, framing, and quantity information.

Project measurements and costs

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

Measured project details

  • Vehicle And Door Clearances

    HomeCat captures bay widths, parking depth, overhead-door sizes, turning clearance, and the path from each vehicle door to the exit.

  • Foundation And Spans

    HomeCat measures slab edges, footing runs, post locations, wall lengths, header spans, ceiling spans, and roof-bearing lines.

  • Storage And Openings

    HomeCat coordinates windows, service doors, workbenches, cabinets, equipment zones, and clear circulation around parked vehicles.

Material and cost inputs

  • Slab And Foundation

    The measured footprint and perimeter support quantities for excavation, granular base, concrete, reinforcement, forms, and anchor hardware.

  • Wide Opening Structure

    Overhead-door widths and roof spans define the headers, beams, posts, trusses, and connectors that shape structural pricing.

  • Doors And Building Systems

    The coordinated plan includes overhead doors, glazing, electrical points, ventilation, insulation areas, and interior finish quantities for estimating.

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 needed for a detached garage permit?

A typical package includes a site plan, garage floor plan, elevations, foundation or slab details, wall sections, and roof or framing information. HomeCat checks the property's zoning automatically and tailors the package to the garage size, construction, and permit scope.

Do garage plans need to show the property lines?

The building drawings do not, but the site plan usually does. Reviewers use it to check setbacks, lot coverage, access, and the garage location relative to the house and other structures.

Can garage plans include a workshop or storage loft?

Yes, but the intended use affects the layout, structure, stairs, fire separation, height, and code requirements. Describe the use at the start so it is part of the design.

Should I choose the garage door size before the plans are made?

Yes. Door width and height affect vehicle clearance, wall layout, headers, roof loads, and the exterior elevation. Standard sizes also make pricing and sourcing easier.
