Custom Designed Accessory Dwelling Units (ADU) fitting within your site and family needs. Douglas has individually designed and managed over 60 homes (Including many Accessory Dwelling Units and Small Homes/Cabin Retreats) throughout Southern California in his over 20 years of experience. Many of these homes have been featured in Publications and received Design Awards.  Douglas also lived in an ADU during his graduate studies, and lived in a 400 SF Unit for 10 years and an 800 SF Unit for over 10 years as well.  This allows him to understand the unique challenges and opportunities in small living.

guide:

Below is a guide to frequently asked questions.  Please note these are generic and your indivual project, site, State or Jursidiction may differ

OVERVIEW (STATE OF CALIFORNIA):

....................................................................................................

Two new Accessory Dwelling Unit (ADU) State bills, Assembly Bill (AB) 2299 and Senate Bill (SB) 1069 that amended the State’s existing second unit law (Government Code Section 65852.2). These amendments to the existing second unit law went into effect on January 1, 2017. The new version of State law makes clear that City ordinances which do not align with State law shall be “null and void” and that, until which time a jurisdiction adopts its own ordinance, in accordance with State law, the state standards specified in section 65852.2 shall be enforced.

LOCAL CODES:

....................................................................................................

Many local Jurisdictions have enacted their own ordinances further defining the development standards and where or if Accessory Dwelling Units (ADU) are allowed.  Please refer to your local Planning/Building Departments or contact Douglas Peters>architect for an overview of the restrictions for your home.

GENERAL STATE OF CALIFORNIA LAW REQUIREMENTS:

  • Single-Family Residence must exist on the Property.
  • ADUs must provide their own dedicated entrance, bathroom, and kitchen.
    • (Check with your local jurisdiction as to minimum requirements for a kitchen's set of appliances are required, such as using a mini-fridge and cook-top.  However Microwaves as the only heating source has been rejected in the past.)
  • ADUs that are attached to an existing single-family dwelling cannot be larger than 50% of the existing living areas.
  • Both attached and detached ADUs cannot exceed 1,200 square feet.
    • Though local jurisdictions further restrict this size
  • No passageway shall be required in conjunction with the construction of an ADU.
  • No setbacks shall be required for an existing garage that is converted to an ADU.
  • An ADU that is constructed above a garage will need to provide no more than five feet from the side and rear lot lines.
  • Existing accessory structures, with side and rear setbacks sufficient for fire safety, and with their own exterior entrance shall be permitted to become ADUs.
  • Parking:  The state legislation limits the required parking for an ADU to one parking space per unit or per bedroom and permits the parking space to be a tandem space in an existing driveway. When a garage, carport or covered parking structure is demolished in conjunction with the construction of an ADU the replacement spaces may be located in any configuration on the same lot as the ADU, including, but not limited to, as covered spaces, uncovered spaces, or tandem spaces, or by the use of mechanical automobile parking lifts.  Additional Parking may not be required based on your proximity to major Transit Stop, 1/2 mile.

....................................................................................................

DEVELOPMENT RESTRICTIONS  TO CONSIDER:

....................................................................................................

  • SHORT-TERM RENTAL (Airbnb):  California State rules leave it up to local governments to decide whether ADUs can be listed on short-term rental sites like Airbnb. Some, like Santa Monica, Long Beach, and Los Angeles County, have chosen to ban ADUs from short-term rental use in order to encourage owners to lease them out for longer periods of time.  Homeowners aiming to build a rental unit for vacationers should definitely check local rules in their area before starting on the project.
  • HEIGHT LIMITS: Local jurisdictions define the allowable height of Accessory Structures, and ADUs.
  • HILLSIDE/HIGH-FIRE:   Many jurisdictions have created restrictions for ADUs in Hillside/High-Fire Zones.
  • CONVERSIONS:  Depending on the age and permit history of the structure being converted into an ADU, you may have to complete foundation, framing, and Mechanical/Electrical/Plumbing upgrades adhering to the current codes.  Garage Conversions will likely require demolition of the slab and reinforcing the foundations with a new slab poured along with framing upgrades.  Consult a licensed Structural Engineer.
  • CONSTRUCTION COSTS: An ADU is essentially building a small home.  Meaning it has all the components that make building one expensive.  Every trade is required.  Therefore construction costs are much higher than one would expect as there is typically very little "economy of scale", as labor is still required.
