Yes. You can complete your purchase as a guest. However, creating an account makes it easier to access your downloads in the future. We recommend creating one.

We accept all major credit cards (Visa, Mastercard, American Express, Discover), PayPal, Apple Pay, and Google Pay through our secure Shopify checkout.

Because plan sets are digital downloads, all sales are final once the download link has been accessed. If you have not yet downloaded your plan and believe you purchased in error, contact us immediately at info@infillplans.com and we will review your request. We want every buyer to make a confident, informed purchase — please
review all plan specifications carefully before checkout.

Yes. Our plans are drawn to the International Building Code (IBC) and are designed to be submitted directly to most U.S. building departments for a permit. However, every
jurisdiction has its own local amendments, zoning overlays, and administrative requirements. We cannot guarantee approval in any specific jurisdiction. We
strongly recommend confirming local requirements before purchase.

This depends on your state and local jurisdiction. Some states require that construction documents for residential buildings be stamped by a locally-licensed architect or engineer. Check with your local building department or ask your general contractor — they will know the requirements in your area. If a local stamp is
required, our partner architects or a local architect can typically provide a plan review and stamp for a fee significantly lower than drawing new plans from scratch.

Yes, modifications are common and expected. Our plans are starting points — our partner architects, a local architect, or a structural engineer can adapt them for your specific site conditions, local code amendments, or personal preferences. We do not provide modification services directly, but contact us if you need a referral. Note: all modifications must be performed by a licensed professional and do not affect the validity of your single-build license.

Each plan lists a minimum lot width and depth. If your lot is slightly smaller than the minimum, the plan may still work with minor modification — but this should be confirmed by a licensed designer before purchase. If your lot is significantly smaller, we recommend filtering for plans with a lower minimum dimension or contacting us for guidance.

Our plans are based on the International Building Code and are designed for use throughout the United States. However, California, Florida, New York, and a few other states have significant state-specific code amendments that may require plan modifications. Always verify with your local building department.

A single-build license permits you to construct one structure using the purchased plan. You may print as many copies of the plan as you need for your build team. You may not share, resell, or use the plan to construct additional homes without purchasing a multi-build license.

We offer multi-build and developer licensing for builders who want to use the same plan for more than one structure. Contact us at [your email] with the number of builds you're planning and the plan(s) you're interested in. We'll provide a custom quote.

Yes. You are licensed to share the PDF files with your contractor, architect, engineer, and any other members of your build team for the purpose of constructing the single permitted structure. You may not distribute the files to third parties outside your project team or create copies or derivatives for resale purposes.

All plans are delivered as PDF files. Sheets are sized at 24" × 36" — the standard size for professional print shops and most building department permit desks. Some plans also include an 11" × 17" reduced set for reference.

CAD files (.dwg or .dxf) are available for select plans at an additional cost. If you need CAD files, contact us before purchasing to confirm availability and pricing for the specific plan you're interested in.

Yes, if the plan is designated as an ADU plan. Check the plan's specifications for 'ADU Eligible: Yes.' Note that ADU regulations vary widely by city — maximum size, setbacks, owner-occupancy requirements, and design standards all differ. Confirm your city's ADU ordinance before purchasing.

A site plan shows the position of the building on the specific lot, including property lines, setbacks, utility connections, and landscaping. Our plans include a site plan template — a pre-drawn building footprint at the correct scale — but the lot-specific data (your property lines, dimensions, and survey information) must be added by a licensed surveyor, builder or civil engineer. Most building departments require a completed site plan with the permit application.
