Land use
Is a second dwelling, primary dwelling, ADU or converted accessory building allowed on this parcel? Ask about setbacks, lot coverage, parking, utilities and occupancy—not just “are tiny houses legal?”

Before you turn a shed into a tiny house.
A storage building can look like an inexpensive shell. The expensive question is whether the shell can legally and safely become a dwelling where you want to use it.
The first principle
Treat it as a change of use, not a decorating project.
Do not start with flooring, cabinets or paint. Start with the local planning/building office and the actual structure. A building sold as storage may not have been designed, permitted or documented as habitable residential construction.
The right sequence is placement → classification → structure → life safety → utilities → moisture/ventilation → finishes.
Go / no-go screen
Find the blockers before the remodel.
Answer with what you know today. “Unknown” is not a failure—it tells you what to verify before buying or converting the building.
What to inspect
Six systems matter before the finishes.
Structure
Confirm foundation/anchorage, floor capacity, roof and wall framing, wind/snow/seismic requirements where applicable, and whether alterations need engineered documentation.
Escape & fire safety
The 2024 IRC requires emergency escape and rescue openings for sleeping rooms and certain sleeping-loft conditions. Your adopted local code controls the exact requirement.
Utilities
Electrical service, potable water, wastewater, plumbing venting, heating/cooling and fuel-burning equipment all need a code-compliant path. A convenient extension cord or garden hose is not a residential utility plan.
Moisture & ventilation
Small, tightly insulated spaces can accumulate moisture quickly from cooking, showers and occupants. EPA emphasizes moisture control and adequate ventilation as core indoor-air-quality strategies.
Paper trail
Keep plans, permits, inspections, product data, photos before walls close, receipts and any engineering. That record can matter later for insurance, resale, repairs and proving what is inside the assembly.
