Grow Your Rental Income with ADUs

What if you could increase your rental income without buying a new investment property? What if you could add units to your current property, attract new residents, and manage the project seamlessly and cost-effectively? ADUs are a great way to add rentable units to your existing property quickly and without breaking the bank.

What is an ADU?

ADU stands for Accessory Dwelling Unit. They’re sometimes called granny or in-law units. They can be up to 1,200 sq. ft. and can be built on single-family or multi-family residential buildings depending on local permits. An ADU is required to provide facilities for living, sleeping, eating, cooking, and sanitation.
With some relatively simple changes, you could transform unused spaces around your property into ADUs or split existing units into 2 or more ADUs depending on size.

How to Get Started

  • Step 1: Identify space or location to build or remodel your ADU
  • Step 2: Check with all local, state, and federal laws governing ADUs to make sure your project is in compliance.
  • Step 3: Construction. Choose an experienced resource to help bring your project to life.
  • Step 4: Rent your new ADU building at market value to see the highest ROI

The Cost-Benefits of Building ADUs on Multifamily Properties

  • While the cost of building new accessory dwelling units in your existing multifamily property may be in-line with a larger-scale renovation or construction, the short and long-term benefits can be substantial.
  • Short term, as soon as your new units are finished, they can be rented quickly and start adding income.
  • Long term, if you decide to sell your property, it will fetch a higher price with the additional units and the increased rental income.

Frequently Asked Questions(FAQs)

While the cost of building new accessory dwelling units in your existing multifamily property may be in-line with a larger-scale renovation or construction, the short and long-term benefits can be substantial. As soon as your new units are finished, they can be rented quickly and start adding income. Long term, if you decide to sell your property, it will fetch a higher price with the additional units and the increased rental income.

An ADU must have at least 150 square feet of living space. The maximum squarefootage for a one-bedroom ADU is 850 or 1,000 for a two+ bedroom unit. Some cities and counties in CA will allow up to 1,200 square feet for a multi-bedroom ADU.

You can build up to 2 detatched ADUs. Or, you can covert existing, internal space into ADUs up to 1 for every 4 existing units you currently have.

You cannot sell an ADU separately from the rest of the property. However, if or when you do sell the whole property, an ADU can add value.

California laws supercede HOA rules. So in many cases, HOAs cannot prevent homeowners from building an ADU on their poperty. However, it's important to comply with HOA policies on paint colors, etc. and follow rules about where ADUs can be placed with the property line.
