Parcel Feasibility: Can You Build on This Land?

APN, jurisdiction, parcel size, road access, zoning, setbacks, utilities, septic, fire, flood, slope, and easements.

Start with the legal category

A small home can be reviewed very differently depending on whether it is a primary dwelling, accessory dwelling unit, junior ADU, manufactured home, modular home, park model, RV, or movable tiny home. Before buying or designing, ask the planning department which category applies to your exact proposal.

Then check the land

Zoning, lot size, setbacks, easements, road access, fire access, flood zones, slope, utilities, sewer, septic, wells, and overlays can matter more than the size of the structure. A beautiful tiny home cannot solve a parcel that lacks a permitted pathway.

State rules do not replace local review

California ADU law creates strong statewide rights, but local objective standards and site conditions still affect design. Tiny homes on foundations can use residential building-code concepts, while tiny homes on wheels often face separate local occupancy and vehicle rules.

  • Confirm whether the parcel is inside a city or unincorporated county.
  • Ask for the zoning district, overlays, setbacks, and allowed residential uses.
  • Verify sewer, water, electric, gas, fire flow, and any connection fees.
  • If septic or well is needed, contact environmental health before assuming feasibility.
  • Document every answer with department names, dates, links, and code references.

Educational estimate only. Tiny home, ADU, zoning, utility, septic, and building-code rules vary by parcel, city, county, zoning district, overlays, and utility provider. Always confirm with the local planning department, building department, environmental health department, fire authority, and utility provider before buying land, designing, permitting, or building.
