Understanding Accessory Dwelling Units (ADUs) in Santa Monica
Accessory Dwelling Units (ADUs), often called granny flats, in-law suites, or backyard cottages, are self-contained living spaces located on the same property as a primary residence. ADUs have gained popularity across Santa Monica and Southern California due to their ability to provide additional housing, generate rental income, and increase home value.
Benefits of Building an ADU in Santa Monica
- Increased Property Value – An ADU can raise your home’s market worth, making it a smart long-term investment.
- Rental Income – ADUs offer a lucrative opportunity to generate passive income by renting out the unit.
- Multigenerational Living – Homeowners can provide a comfortable space for aging parents or adult children while maintaining privacy.
- Sustainable Housing Solution – With California’s push for more housing, ADUs are an eco-friendly way to increase housing density without major urban sprawl.
Types of ADUs You Can Build in Santa Monica
- Detached ADUs – A standalone structure, typically in the backyard.
- Attached ADUs – An expansion of the main home, sharing at least one wall.
- Garage Conversions – Transforming an existing garage into a fully functional living space.
- Basement or Internal ADUs – Converting part of an existing home into a separate unit.
Pro Tip: Before choosing an ADU type, assess your property’s size, zoning regulations, and intended use. FTR Renovation & Build specializes in helping homeowners determine the best ADU option for their property.
A Deep Dive into Santa Monica’s Zoning Laws
While California law encourages ADU development, Santa Monica maintains specific zoning regulations that determine where and how ADUs can be built.
Key Zoning Regulations for ADUs in Santa Monica
- Lot Size Requirements – While Santa Monica allows ADUs on most residential lots, specific size restrictions apply.
- Setback Rules – ADUs generally need a 4-foot setback from side and rear property lines.
- Height Limits – Detached ADUs are often limited to 16 feet in height, but exceptions exist for two-story units.
- Parking Requirements – Santa Monica typically waives additional parking requirements if the ADU is near public transit.
- Owner-Occupancy Rules – As of recent state laws, owner-occupancy requirements for ADUs have been lifted until at least 2025.
Pro Tip: Zoning laws can be tricky, but an expert can help simplify the process. Schedule a consultation with FTR Renovation & Build to ensure your ADU meets local regulations.
The Role of California State Laws in Shaping ADU Regulations
Santa Monica’s zoning laws must align with California state laws, which have evolved to promote ADU development.
Key California ADU Laws That Affect Santa Monica
- Senate Bill 9 (SB 9) – Allows homeowners to split lots and add multiple units, making ADU development more accessible.
- AB 68 & AB 881 – Reduce ADU approval times and eliminate minimum lot size requirements.
- SB 13 – Prevents excessive local fees and eliminates owner-occupancy requirements until at least 2025.
State vs. Local ADU Regulations
While California laws override restrictive local zoning codes, cities like Santa Monica still set regulations on setbacks, height limits, and architectural design requirements.
Did You Know? Homeowners in Santa Monica can now build both an ADU and a Junior ADU (JADU) on the same lot, allowing for increased rental potential and multi-generational housing solutions.
Navigating the Permit Process for Building an ADU in Santa Monica
Building an ADU requires approval from the City of Santa Monica, and obtaining permits is a crucial step in the process.
Steps to Getting Your ADU Permit Approved
- Check Zoning Laws – Ensure your property qualifies for ADU construction.
- Develop ADU Plans – Work with an experienced builder to design your ADU while meeting zoning requirements.
- Submit Permit Application – File your ADU permit application with Santa Monica’s Planning and Development Department.
- Provide Required Documentation – Typically includes architectural plans, site surveys, and environmental impact reports.
