How Do I Sell a Home With an ADU in Los Angeles County?
Selling a home with an ADU in Los Angeles County works best when you market the ADU as an asset, not a footnote: it commonly adds 10 to 30% to value, often a six-figure premium in LA, by appealing to house-hackers, multigenerational families, and investors. The keys are pricing it right, documenting the ADU's permits and rent so it appraises, and pre-qualifying financed buyers so offers close. LA is also an AB 1033 city, so in some cases you can convert the ADU to a condo and sell it separately. Serve First leads the sale; Ashlar Lending qualifies buyers; Ashlar LDA prepares documents at your direction.

How to sell an ADU home in LA County for full value
An ADU can be the reason your home sells higher and faster, or an overlooked feature that adds nothing to the price. The difference is how it's positioned. Here's how Serve First captures the value, with Ashlar Lending and Ashlar LDA in support:
Price the ADU as income, not square footage
A home with a rentable ADU competes with small income properties, not just neighboring houses. Serve First prices it to reflect the rent it produces (often $1,500 to $3,500/month in LA) and the flexibility it offers, so you're not leaving the premium on the table.
Document permits and rental history
This is what makes the premium stick at appraisal. Gather the ADU's permits, final inspection, and any lease/rent records. A documented, legally permitted ADU appraises and finances cleanly; an undocumented or unpermitted one invites lender pushback and price cuts. Serve First helps you assemble the package; Ashlar LDA can prepare related documents at your direction.
Market to the buyers who value it
The right buyer pays more: house-hackers who'll live in one unit and rent the other, families needing multigenerational space, and investors. Serve First markets specifically to these audiences across LA County rather than to general buyers who'd undervalue the ADU.
Pre-qualify buyers so the deal closes
An ADU home draws buyers relying on the ADU's rent to qualify, which can complicate financing. Because Ashlar Lending can pre-qualify those buyers and even credit the ADU's rental income toward their loan, Serve First can prioritize offers that will actually close, widening your effective buyer pool.
Consider the separate-sale option (AB 1033)
Los Angeles is one of the cities that has opted into AB 1033, which lets you convert an ADU into a condominium and sell it separately from the main home. It can unlock value, but it's involved, condo-plan recordation, safety inspections, an HOA under the Davis-Stirling Act, and separate utility metering, and few owners have completed it. Serve First can help you weigh whether it's worth it versus a standard sale; Ashlar LDA can prepare condominium-conversion documents at your direction.
An unpermitted ADU can cost you at the closing table. If the ADU was built or converted without permits, lenders and appraisers may not credit its value, buyers may demand price cuts, and the sale can stall. Before listing, confirm the ADU's permit status, and if it's unpermitted, Serve First can help you weigh legalizing it first (California's rules make this easier than before) against selling as-is with full disclosure.

Market the ADU as the asset it is
An ADU can add real value to your sale, if it’s marketed and documented right. The Ashlar Brands family helps you capture it:
- Serve First Realty prices and markets your ADU home to the buyers who value it, house-hackers, multigenerational families, and investors, and documents the ADU’s permits and income so the value holds up in appraisal and negotiation.
- Ashlar Lending (NMLS #2699657) can pre-qualify your buyers, including using the ADU’s rental income to help them qualify, so a financed offer closes with confidence, widening your buyer pool.
- Ashlar LDA, Inc., a bonded and registered Legal Document Assistant, can prepare deeds, disclosures, and (in cities that allow the separate sale of an ADU) condominium-conversion documents at your direction.
These are separate businesses in the Ashlar Brands family. Serve First is a real estate brokerage, not a lender or law firm. A Legal Document Assistant prepares documents at your direction and is not a substitute for an attorney.

Frequently asked questions
How much does an ADU add to my home's value?
Typically 10 to 30%, and in a high-value market like LA that's often a six-figure premium. The exact lift depends on whether the ADU is permitted, its size and condition, and the rent it can command. The premium is largest when the ADU is documented and marketed as income, which is where Serve First's pricing and marketing matter.
Does the ADU need to be permitted to sell?
You can sell an unpermitted ADU, but it usually costs you. Appraisers and lenders may not credit its value, some buyers will walk or discount, and you must still disclose it. A permitted ADU appraises and finances cleanly and commands the full premium. Serve First can help you decide whether to legalize it first or sell as-is with full disclosure.
Can I sell my ADU separately from the main house?
In some California cities, yes, under AB 1033, which lets local agencies allow ADUs to be converted to condominiums and sold separately. Los Angeles, San Diego, San Jose, Berkeley, Sacramento, and Santa Monica are among the cities that have opted in. The process involves condo-plan recordation, inspections, an HOA under the Davis-Stirling Act, and separate metering, so it's not simple. Serve First can help you weigh it.
Who buys homes with ADUs?
Three main groups: house-hackers who live in one unit and rent the other to offset their mortgage, families who need space for parents or adult children, and investors seeking rental income. Marketing to these buyers, rather than to general buyers who see the ADU as a bonus room, is what captures the premium. Serve First targets them directly.
Will an ADU make my home harder to finance for buyers?
It can, if the ADU is undocumented or the buyer needs its rent to qualify, but that's manageable. Because Ashlar Lending can pre-qualify buyers and credit ADU rental income toward their loan, Serve First can steer toward offers that will close. A well-documented, permitted ADU actually broadens your buyer pool rather than narrowing it.
