How to research an ADU rent scenario in Los Angeles

A cautious way to compare long-term, mid-term and short-term rental assumptions using current local evidence and a complete operating-cost model.

Key takeaways

  • 1-bed 600 sq ft, west side: pull current comparable listings for the exact submarket — west-side rents typically run above eastside/valley comps for the same unit size.
  • 1-bed 600 sq ft, eastside / valley: check comparable listings and HUD Fair Market Rents for the specific ZIP code.
  • 2-bed 900 sq ft, west side: compare against active listings for detached 2-bed units near your address.

The honest answer to 'what does an ADU rent for in LA' is: it depends on neighborhood, rental strategy, and how realistic your operating costs are. Pull current comparable listings for the specific neighborhood and unit size, or check HUD Fair Market Rents for the LA metro area as an area-wide reference point, not an ADU-specific figure. Stress-test your numbers against your specific lot in the ROI calculator.

Long-term rentals (12-month leases)

  • 1-bed 600 sq ft, west side: pull current comparable listings for the exact submarket — west-side rents typically run above eastside/valley comps for the same unit size.
  • 1-bed 600 sq ft, eastside / valley: check comparable listings and HUD Fair Market Rents for the specific ZIP code.
  • 2-bed 900 sq ft, west side: compare against active listings for detached 2-bed units near your address.
  • 2-bed 900 sq ft, eastside / valley: compare against active listings and note how proximity to transit and schools shifts asking rent.

Mid-term rentals (30+ day stays)

Furnished, 30-day-minimum stays may serve traveling professionals, relocating households or people displaced during repairs. Compare current furnished and unfurnished listings for the same neighborhood and unit type, then account for furniture, utilities, turnover and vacancy. Confirm the proposed lease structure and local rules before treating this as a viable use.

Short-term rentals

LA's Home-Sharing Ordinance restricts short-term rentals to a host's primary residence. An ADU on the same parcel can qualify under specific conditions, but enforcement is active and getting stricter — short-term should never be the only model your pro forma supports.

What the marketing pro formas leave out

  1. Property management — get current management fee quotes from local property managers before assuming you'll self-manage.
  2. Vacancy — build a vacancy assumption from your own rental strategy and turnover expectations, not a single citywide average.
  3. Maintenance reserve — budget an annual reserve sized to the unit's finishes and systems; a property manager can help set a realistic figure.
  4. Property tax reassessment — California Prop 13 protects the existing improvement, but the new ADU is reassessed at market. The reassessment guide shows the exact math.
  5. Insurance — get a landlord policy quote for the specific address and unit before finalizing your pro forma.
