ADU Tips for Los Angeles Homeowners
Building a new accessory dwelling unit in Los Angeles is a big undertaking. If you’re feeling anxious and stressed out over your project, it’s only natural. Finding the right contractor is critical. Unfortunately, the truth is that the majority of homeowners end up having a negative experience with their ADU contractor.
To increase the chances of having a satisfactory ADU experience, be sure to follow these tips when contacting a contractor:
Research. Find out what other people in your area have paid for similar ADU projects, and adjust your expectations accordingly.
Get an estimate. Contact a minimum of three contractors in your area and get a cost estimate from each.
Be wary. Look for signs that a contractor may not be right for you. “Red flags” include a contractor who takes too long to call you back or tries to pressure you into making a deal.
Don’t make a quick decision. You shouldn’t hire a contractor just because their prices seem low, or because you have a “good feeling” about them.
Make a list. Figure out what features you want to be included in your ADU. Make sure every contractor gets the same list, so every estimate is based on the same terms.
Don’t pay a large deposit. Under California law, a contractor cannot require you to pay more than $1,000 upfront.

Accessory Dwelling Unit FAQs
What does ADU mean?
An ADU is otherwise referred to as an accessory dwelling unit, additional dwelling unit, secondary suite, or granny flat. Put simply, it is a secondary structure on a residential lot in addition to the main house – this includes converting a detached or attached garage into a full living quarters. The main elements of an ADU are a kitchen, a bathroom, and a ‘living space’. An ADU garage conversion is a common form of ADU unit.
Why build an ADU on your property?
An accessory dwelling unit relieves many problems and allows for a ton of flexibility of uses. People are building them to use as extra space (an office or guest house), a music or yoga studio, a mancave or she-shed, or a home for their retired parents or grown children.
What kind of ADUs are there?
The two primary options are either building a new unit in the backyard or converting an existing garage to an ADU. It can be attached to an existing home, attached to a garage in the rear of the lot, or detached completely.
How much does an ADU cost?
An accessory dwelling unit will vary greatly in cost based on the options and size you choose. The cost for an ADU garage conversion can usually range from $95,000-$120,000 depending on the homeowner’s requirements. Costs to construct a new accessory dwelling unit will generally range from $150,000-$400,000. A safe rule of thumb is to assume any new construction costs $300-$400 per square foot – the bigger the space, the lower cost per square foot. It will also depend on the price your ADU contractor charges for their work.
How long does it take to build an ADU?
For a garage conversion, you can expect the entire process to take 3-6 months. A new accessory dwelling unit will take longer for city plancheck and require a longer construction process, so you can expect the entire process to take 6-9 months, with the construction phase lasting 3-6 months.
Who can build an ADU?
The city of Los Angeles has allowed ADUs on most residentially zoned lots regardless of their size as long as the structure meets the basic restrictions and there is an existing home already on the property. ADU’s are also allowed on multifamily properties such as duplex, triplex, four-plex, and apartment buildings.
How do I hire a good ADU contractor?
When looking to build an accessory dwelling unit or even starting to explore the idea, it’s best to search for only local, licensed General Contractors. No other contractors are qualified or equipped to do this sort of construction, and using an unlicensed contractor or handyman would be a mistake.
Can I legalize an unpermitted Accessory Dwelling Unit or garage conversion?
Yes, but you will need to bring it up to code and pay for the construction that is required. A good contractor can look at your property and give a rough estimate of the costs involved. Learn more about this specific situation here: https://www.greatbuildz.com/blog/unpermitted-los-angeles-garage-conversion/
Do I connect ADU utilities to the existing home?
It depends on which city you live in. In Los Angeles, you must connect your water & sewer directly to the water meter & main sewer lateral.
If I have DWP power lines at the back of my property, where can I build an ADU?
A new accessory dwelling unit or garage conversion which is more than 10’ away from the edge of the powerlines is acceptable. An ADU within 10’ of the powerlines must file for a DWP encroachment permit (current processing time is 3-4 months). A garage that is currently under the powerlines may not be converted to an ADU.
Can I sell an ADU without my house?
No, an ADU cannot be sold separately from the main home.
Do ADUs require pedestrian access?
Yes, walking path access of 3’ wide is required from the front yard/sidewalk to the ADU (a driveway is acceptable).
Must I live on the property?
No, you can rent both the main house and the ADU. However, if you are building a Junior ADU, then owner-occupancy is required.
What are the ADU permit costs for Los Angeles city?
There is an LA City permit fee calculator you can find here: https://www.ladbs.org/services/pay-fees/permit-fee-calculator

Is an ADU right for retired people?
An ADU housing unit becomes the optimum living arrangement in retirement in many respects. Having a house of one’s own helps a person to preserve independence and pride. And being on the same property and within a few feet of their family or support network is crucial when the need for assistance arises. This is especially true for retired individuals who opt to stop driving. Even though retirement is a delicate balance between independence and assistance, an ADU may be the best of both worlds.
Can I act as a general contractor and build my own ADU?
It is probably a mistake to save money by operating as your own general contractor. Although you believe this may save you money, it’s a horrible idea unless you are really skilled or have a vast network of subcontractors (plumber, framer, roofer, foundation, electrical, stucco, drywall, etc,). When you choose an ADU contractor (or general contractor), you are not only paying them to oversee the project, but also for their relationships with the crew, employees, and subcontractors who can complete the project successfully. It is quite difficult for you to find skilled tradespeople. And if one of these contractors performs poorly, you will have to pay twice to repair their errors.
How do I compare ADU contractor estimates?
Regardless of the specifics of your project, you should pay your ADU contractor a reasonable fee. Obtain three to five bids from various ADU contractors prior to making a final decision. If all of the bids are somewhat comparable in price, it indicates that your project is ‘clear’ to each contractor and that their pricing is likely in line with the market. However, if your estimates are inconsistent, it indicates that something is wrong. Either your project’s specifications are unclear, or your contractors’ bids are unrealistically high or cheap. In this instance, obtaining several bids will assist you determine the job’s suitable pricing.
Is an ADU a good investment?
ADU investments have become an appealing financial prospect for investors. Real estate investors or first-time investors previously chose to purchase a duplex or triplex, but now have a new alternative. The ADU investment opportunity is quite straightforward: buy a single-family house with the option to add an ADU and/or junior ADU, and construct one or both. This ADU investment has transformed the property from a single-family dwelling to a duplex or triplex. An ideal property has sufficient backyard space or a detached garage that can be transformed into an ADU. Now, the ADU investor may rent the units to numerous tenants and generate several streams of rental revenue from a single property.
