Frequently Asked Questions About ADUs in Los Angeles


Are tiny homes allowed in Los Angeles?

Yes. The Los Angeles City Council accepted California’s Accessory Dwelling Unit (ADU) ordinance. The ordinance makes tiny houses allowable and permanent inhabitation ADUs or backyard cottages.


Where can I put a tiny home in Los Angeles?

An ADU is permitted in Los Angeles County IF:

  • The property is zoned to allow a single-family residence (SFR) or multi-family residence (MFR). For coastal areas, refer to the applicable Local Coastal Program.
  • A legal SFR or MFR exists on the property or is proposed to be built concurrently with the ADU(s).

In Los Angeles County, an ADU is defined as a unit with a full kitchen and bathroom that is accessory to a residential property. The ADU can be on a property with a home or apartment building (detached or attached).

“Extremely respectful polite and professional”

“I was looking for a really beautiful tiny house to put on my back deck for an extra bedroom. While backyard unlimited costs more than their competitors, the house has a really unique and cool design (with 7 windows and a slanted roof going up to 11 ft), they were very prompt and friendly, they delivered it 2 to 3 weeks early, and all of the people I spoke with were extremely respectful polite and professional. I cannot recommend them enough.”
