Humboldt Associaton of Realtors, in conjuction with the Humboldt County Community Development Services, has made available to the public construction plans for four (4) different pre-approved Secondary Dwelling Unit (SDU) designs. Sometimes called a mother-in-law unit, a SDU can provide an affordable living unit for anyone. By providing pre-approved construction plans, the cost to build this type of housing is reduced because there are no architect/designer fees necessary.

Copies of all four pre-approved designs are kept at the Humboldt County Building Division's front counter and are available for review upon request.

How to contact the Humboldt County Building Division:

If you have any additional questions, contact the Humboldt Association of Realtors at (707) 442-2978 or email kristen@harealtors.com.
