Canyon Country is a community of the City of Santa Clarita, so most Canyon Country homes follow Santa Clarita’s building, planning and code rules, although a few nearby pockets may be unincorporated county land. This guide explains how those rules apply and what to check before you sell.

Who governs a Canyon Country home

Santa Clarita runs its own Building and Safety Division and Planning Division. For a house inside city limits, those two offices decide permits, inspections, zoning and ADUs. Because some addresses with a Canyon Country mailing area sit outside the city, confirm the jurisdiction for your parcel first.

If it is unincorporated, Los Angeles County Public Works and Regional Planning apply instead, as described in our Los Angeles County page and the Ladera Heights and Alondra Park guides.

Our full city guides cover building permits, code enforcement and zoning and ADUs in detail. This page focuses on what a Canyon Country seller should do.

ADUs in Santa Clarita

Santa Clarita’s planning FAQ states that the city has adopted an ADU ordinance with which all ADUs and junior ADUs must comply.

The city publishes ADU and JADU building plan requirements, which note that approval from agencies such as Santa Clarita Planning may be required before a building permit issues, and it publishes a JADU deed restriction form.

A JADU is considered legal only while the owner lives in either the main unit or the JADU, which matters for resale.

The city’s planning hearing records also show that an accessory structure that is not permitted as an ADU is not permitted as living space, so a converted shed or casita without approval is a real risk for sellers.

Permits and unpermitted work

The city’s Building and Safety Division enforces the 2022 CALGreen residential measures, which the city publishes for homeowners, and builders must follow the current California codes. A common Canyon Country issue is an older garage conversion, patio enclosure or backyard unit done without a permit.

Those items show up when a buyer’s inspector or a lender compares the home with city records. See our statewide as-is guide for how disclosure works.

What to check before selling

  • Confirm the parcel is inside the City of Santa Clarita.
  • Request the city’s permit history for the address.
  • List any converted space, enclosed patio or backyard unit without a permit.
  • If you have an ADU or JADU, find the approval and any recorded deed restriction.
  • Check the seller closing costs guide so you know what comes out of proceeds.
