Accessory Dwelling Unit - Rural

Rev 6.3.24

What is a rural accessory dwelling?

A rural accessory dwelling unit (RADU) is an additional smaller, subordinate dwelling unit on a lot with an existing or new house.  An RADU is an attached dwelling unit that provides a greater range of housing types in Rural and Resource lands while maintaining rural community character and ensuring the conservation, enhancement, and protection of resource lands.

An attached RADU means sharing a common wall or walls. A rural accessory dwelling unit that meets the requirements of this code section may be allowed in the R-20, R-10, R-5, RC-1, RC-2.5, AG-20, FR-40, FR-80, and AG-WL zones, except as noted in the code.

What conditions will allow for the establishment of an RADU?

A rural accessory dwelling unit may be created through the following:

  • Internal conversion within an existing dwelling;
  • Additions to an existing house or attached garage;
  • Conversion of an attached existing garage; or
  • Inclusion as part of construction of a new single-family dwelling.

Does a rural accessory dwelling need a building permit?

Yes. An RADU shall comply with applicable building, fire, and health and safety codes. An RADU cannot be occupied until a Certificate of Occupancy is issued by Building Safety.

Do I have to connect to water and septic?

Yes. A rural accessory dwelling unit shall connect to water and a septic system. A Clark County Public Health Septic System Release/Water Adequacy Verification form needs to be completed by Public Health prior to the issuance of the building permit.  If you have access to Clark Public Utilities Water, then you must visit the utility and have them document the availability of water prior to the issuance of the building permit. A fire flow letter may be required.
