When you receive an Order To Comply (OTC) stating that your property violates Code, read the order carefully to identify which items:
- require a permit
- find contact information for the inspector or supervisor
- determine what fees maybe applied and penalties if not paid on time
- determine appeal procedures
The current property owner is responsible for complying with the Order, even if previous owners or tenants have performed the un-permitted work or created the violation.
Refer to the Obtaining Permits to Resolve Orders (.pdf) information bulletin for more detail.

LAMC 12.22 A.33(b)(3) states that a MTH shall be approved if in compliance with all of the provisions in Paragraph (c), except for those provisions that apply solely to buildings and structures (as well as all of the provisions in Paragraph (f)). This is because MTHs are not considered “structures” under the Zoning Code or Building Code. The following standards in LAMC 12.22 A.33(c) do not apply to MTHs, as they apply solely to buildings and structures (LADBS may determine that other standards do not apply to MTHs):
- Building Code regulations (LAMC Section 12.22 A.33(c)(9))
- Fire sprinkler requirements (LAMC Section 12.22 A.33(c)(10
