Baldwin Park

Baldwin Park permits ADUs and JADUs on residential properties and processes them through ministerial review (no discretionary approval required) when standards are met. ADUs are allowed on lots with an existing or proposed residential dwelling. 

‍

The city allows one ADU and one JADU on single-family lots, with additional allowances for multifamily properties. ADUs must comply with building, fire and design standards and cannot be sold separately from the primary dwelling.

Baldwin Park aligns with California’s broader ADU legislation but has its own requirements for height, setbacks and design review.

• Detached ADU: New detached units are permitted as separate structures on the same lot.
• Attached ADU: New attached units are allowed and connected to the primary dwelling.
• Conversion ADU: Conversion of existing space (such as within the primary residence or existing structures) is permitted, with no maximum size for converted ADUs.
• Junior ADU (JADU): Allowed within an existing or proposed single-family residence, limited to 500 sq. ft.

• Maximum Size:
  
  • Detached: 850 sq. ft. (1 bedroom or less) or up to 1,000-1,200 sq. ft. depending on lot size.
  • Attached: 850 sq. ft. (1 bedroom or less) or up to 1,000-1,200 sq. ft. depending on lot size and bedroom count.
    
    
• Setbacks:
  
  • Minimum 4 feet side and rear setbacks for new detached ADUs; no setback required for conversions unless needed for fire/safety
    
    
• Height Limits:
  
  • Detached: Maximum 18 feet and limited to one story
  • Attached: May match the height and stories of the primary dwelling
    
    
• Parking Requirements:
  
  • One off-street parking space per ADU is generally required
  • Parking may be exempt if the property is within ½ mile of public transit or meets other state exemption conditions
  • No replacement parking is required when converting a garage, carport, or existing structure into an ADU
  • Required parking (if applicable) may be provided as tandem parking or within a driveway

• Ministerial approval required (no discretionary review)
• Building permit required along with electrical, plumbing and mechanical permits
• Submission of site plans and construction documents required
• Deed restriction must be recorded prior to construction stating unit cannot be sold separately
• ADU must comply with California Building Code and local development standards

ADUs are reviewed ministerially, meaning approval is processed administratively without discretionary hearings when all requirements are met.
