There is no universal cutoff for a “small” house: the plan collections reviewed here use under 1,000 square feet as a small- or tiny-home boundary, while Houseplans.com identifies plans under 500 square feet as a subset. Because the exact 40-plan article named in the original title could not be verified, this guide does not invent or reproduce its list. Instead, it explains how to compare small-house plans by their actual area, footprint, room arrangement and build requirements before choosing one.
What counts as a small house?
“Small” and “tiny” are catalogue labels, not standardized categories. AmazingPlans uses under 1,000 square feet for its small-plan collection, while Houseplans.com describes tiny plans as often under 1,000 square feet and identifies a subset under 500 square feet. Those are provider conventions, not an official definition. For a useful comparison, decide what area range works for your household, then check the stated square footage on each individual plan page. AmazingPlans’ small-house collection and Houseplans.com’s tiny-house collection illustrate why it is better to compare actual figures than rely on the label.

Why a 40-plan list cannot be reliably reproduced here
A page matching the “40 best small house plans” concept appeared in search, but it could not be accessed to confirm its plans, specifications, publication date or attributions. A reliable roundup needs current individual plan pages for every entry; without them, presenting 40 model names or specifications would risk passing off unverified details as fact.

The article presents those designs as relevant to ADUs, garage apartments or tiny homes, but it is an illustration of one footprint—not a verified inventory of 40 plans.

Compare the plan, not just the square footage
Two homes with similar area can serve households very differently. Bedrooms and bathrooms matter, but so do how the living spaces connect, where storage sits and whether circulation consumes useful floor area. Before settling on a plan, inspect the catalogue specifications and floor plan together.
- Conditioned area: Record the stated interior area and check what the provider includes or excludes.
- Footprint: Compare the exterior width and depth with the usable building area on your lot, including setbacks and access.
- Room arrangement: Check bedroom and bathroom count, shared or separated sleeping areas, and whether the kitchen, dining and living areas suit daily use.
- Stories and circulation: A multi-story layout may use less ground area, but stairs take space and may not suit every household.
- Storage and parking: Look for closets, utility space and storage needs as well as any garage, carport or off-street parking arrangement.
- Foundation and plan options: Confirm which foundation types are offered and whether the plan can be reversed or modified.
- Intended use: A plan marketed for a primary home, ADU, vacation property or garage apartment may make different assumptions about daily use and site conditions.
These are comparison prompts, not guarantees that a plan will suit a particular property. AmazingPlans specifically advises buyers to consider total area, footprint dimensions, garage arrangement and foundation type when narrowing choices. Review its small-plan collection for the provider’s category and catalogue filters.
Check lot fit and local requirements before ordering
A plan’s stated dimensions do not establish that it will fit your parcel or comply with local requirements. Compare the footprint with a current survey or site plan and account for applicable setbacks, easements, access, utilities and any site constraints. Then contact your local building or planning department and the plan provider about zoning, permits, code requirements, engineering and any adaptations needed for the site.
An Oregon document from 1997 includes narrow-lot designs and notes that some dimensions may be approximate. It can illustrate why narrow-lot layouts and dimension checks matter, but it is historical material—not current legal, price or compliance guidance. Read the historical Oregon narrow-lot guide only as a design reference.
Ask what the plan package includes
Before purchase, read the plan provider’s package description and confirm which drawings and specifications you will receive, whether the plan is suitable for your intended jurisdiction, and what changes or professional review may be necessary. Ask the provider directly about modification and reversal options rather than assuming every plan can be adapted in the same way.
For construction planning, do not treat a smaller floor area as a dependable promise of a lower cost per square foot. Houseplans.com says costs depend on location, materials, size, layout and footprint; it also notes that tiny homes may cost more per square foot even when the total cost is lower. Its guidance is general and does not estimate the cost of a particular design or site. Houseplans.com’s tiny-house collection discusses that trade-off.
