Structure Classification Index
Structure types we track.
Ten alternative structure classifications, each cross-referenced against every jurisdiction's setback, occupancy, and eco-compliance code.

— CLASSIFICATIONS
All Structure Types
A permanently sited, single-occupancy dwelling operating without a mandatory utility grid connection — the most commonly permitted alternative structure class.
A secondary permanent dwelling on a parcel with an existing primary residence, subject to minimum floor-area and setback rules distinct from the main structure.
A tiny house on wheels — regulated in most counties as either an RV/park-model or a permanent dwelling, depending on foundation and hookup status.
Composting Toilet System
A waterless waste system permitted as an alternative or supplement to a conventional septic system, subject to state and county health-code approval.
Earthship / Rammed Earth
Passive-solar structures built from rammed earth, tires, or other dense thermal-mass materials — frequently subject to specialized structural review.
Rainwater Catchment System
A collection and storage system for domestic or agricultural water use, regulated under state water-rights and plumbing code frameworks.
Yurt / Gerdome
A circular, fabric-walled seasonal or permanent structure, treated in most codes as a hybrid between a tent and a permitted dwelling.
Shipping Container Home
Repurposed ISO shipping containers converted to habitable structures, frequently requiring supplemental engineering review for insulation and egress.
Cordwood / Strawbale Construction
Natural-building methods using stacked cordwood or compressed straw-bale walls, permitted under alternative-materials provisions in a growing number of counties.
Solar Micro-Grid Installation
Ground- or roof-mounted photovoltaic systems with battery storage, evaluated against each jurisdiction's grid-tie mandate and interconnection rules.
