*Permits Are Required & Can Be Obtained By Homeowner Or MOUNTAINPEAK CONSTRUCTION
California Has Passed Several Laws To Make Building ADUs Easier For Homeowners. While Local Cities & Counties May Have Additional Guidelines, State Law Sets Minimum Rules That All Jurisdictions Must Follow.
🚫ADU LAWS
Key Laws
-
California Law Allows ADUs On Most Properties That Contain An Existing Or Proposed Residential Home.
• Single-Family Homes Can Usually Build At Least One ADU On The Property.
• Cities Cannot Prohibit ADUs In Residential Zones As Long As The Project Meets State Requirements.
This Law Makes ADUs One Of The Easiest Ways For Homeowners To Add Housing Or Rental Space On Their Property.
-
California Sets Minimum & Typical Maximum Sizes For ADUs.
• Many Cities Allow Up To 1,200 SQ FT For Detached ADUs.
The Final Allowed Size Can Depend On Lot Size, Existing Structures, & Local Development Standards.
-
Setbacks Determine How Close The ADU Can Be Built To Property Lines.
• New Detached ADUs Typically Require 4-Foot Side & Rear setbacks.
• Converting An Existing Garage Or Structure Into An ADU Usually Requires No Additional Setback Changes.
These Reduced Setbacks Make It Much Easier To Build ADUs In Backyards.
-
Recent California Legislation Removed Many Owner-Occupancy Requirements.
• Homeowners Are Generally Not Required To Live On The Property To Rent Out An ADU.
• This Allows ADUs To Be Used As Long-Term Rental Units Or investment Properties.
This Change Has Made ADUs More Attractive For Homeowners Seeking Rental Income.
-
Development Fees Are Limited To Keep ADUs Affordable.
• ADUs Under 750 SQ FT Are Usually Exempt From Impact Fees.
• Larger ADUs May Have Reduced Development Fees Compared To Full Homes.
These Reduced Fees Help Lower The Overall Cost Of Building An ADU.
-
All ADUs Must Comply With California Building & Safety codes.
This Includes:
• Structural Engineering Requirements
• Electrical, Plumbing, & HVAC Systems
• Energy Efficiency Standards (Title 24)
• Fire Safety Requirements Such As Smoke Detectors & Proper Exits
Meeting These Standards Ensures The ADU Is Safe, Durable, & Legally Approved.
