Tiny Home on Foundation Property Feasibility Pathway
A small permanent structure reviewed through a recognized dwelling, ADU, manufactured, modular, or factory-built path.
What this project type usually means
A foundation, building-code path, utility connections, inspections, zoning category, and site plan review.
Why this path can be easier or harder
A foundation can make the review more recognizable than wheels, but the parcel still controls the pathway.
First jurisdiction question
Which local department confirms the structure category and use for the parcel?
Zoning questions
- Is the unit a primary dwelling, ADU, manufactured home, or another category?
- Do minimum size, setbacks, lot coverage, and design standards apply?
Utility questions
- Can permanent utility connections be made?
- Are public sewer/water or electric upgrades realistic?
