Accessory Dwelling Units (ADUs), also known as granny flats, in-law suites, or backyard cottages, are becoming increasingly popular across California. With rising housing demand and legislative support, many homeowners are looking to maximize their property's potential through ADU construction. However, before diving into any project, it's crucial to understand ADU zoning regulations—especially in specific areas like Temecula.

At Trust Company, we specialize in navigating local zoning laws and delivering expert ADU construction services in Temecula. Let's break down the basics of ADU zoning regulations and how they affect your property.

What Are ADU Zoning Regulations?

ADU zoning regulations refer to the local rules and guidelines that govern the construction and use of accessory dwelling units on residential properties. These rules are established by city or county governments and ensure ADUs are safe, functional, and compatible with the neighborhood.

Zoning regulations cover various aspects, including:

  • Lot size requirements

  • Maximum ADU size

  • Setbacks from property lines

  • Height limits

  • Parking requirements

  • Utility connections

  • Occupancy rules

Key ADU Zoning Considerations in Temecula

While California has passed state laws to encourage ADU development, local municipalities like Temecula can still establish specific regulations. Here are some key zoning factors to keep in mind if you're considering an ADU project:

  • Lot Size & Zoning Designation

Not all residential lots are eligible for an ADU. Your property must fall within a zoning district that allows residential use. In Temecula, most single-family and multi-family zones now permit at least one ADU per lot, regardless of size.

  • ADU Size Limitations

Temecula allows detached ADUs up to 1,200 square feet, though this can depend on the lot size and existing structures. Attached ADUs must generally be less than 50% of the main home's floor area.

  • Setbacks & Height Restrictions

Typically, ADUs must meet minimum setbacks from rear and side property lines (e.g., 4 feet). Height is usually limited to two stories or 16 feet, but exceptions may apply based on design and lot layout.

  • Parking Requirements

While state laws have relaxed parking requirements, some properties may still be required to provide parking for the ADU, especially if the unit is not within walking distance of public transit or built within an existing structure.

  • Owner-Occupancy

Recent state updates have removed the owner-occupancy requirement through 2025, allowing greater flexibility for investment and rental opportunities.
