   C.   Continuation of an Existing Land Use. An existing land use is lawful and not in violation of the Municipal Code only when operated and maintained in compliance with all applicable provisions of these Regulations. However, the requirements of these Regulations are not retroactive in their effect on a land use that was lawfully established before these Regulations or any applicable amendment became effective. See Chapter 19.08 (Nonconforming Structures, Uses, and Parcels) for provisions applicable to nonconforming uses.
   D.   Alteration or Expansion of an Existing Land Use or Structure. Alteration, expansion, or modification of an existing land use or structure shall comply with all applicable provisions of these Regulations, specifically including Chapter 19.08 (Nonconforming Structures, Uses, and Parcels). New construction which increases the square footage of an existing structure or a new or changed land use which would increase the required number of parking spaces by three or more additional parking spaces shall comply with applicable standards within Title 19.
   E.   Effect of Amendments on Projects in Progress. The enactment or amendment of these Regulations may have the effect of imposing different standards on new land uses than those that were applied to existing development. For example, these Regulations or a future amendment could require larger building setbacks for a particular land use than former provisions. This subsection determines how the requirements of these Regulations apply to development projects in progress at the time requirements are changed.
      1.   Projects With Pending Applications. Any land use entitlement and subdivision application that has been determined by the director to be complete before the effective date of these Regulations or any amendment will be processed in compliance with the requirements in effect when the application was accepted as complete. Applications for land use entitlement time extensions (see Chapter 19.30 - Permit Implementation, Time Limits, Extensions) shall comply with these Regulations as they exist on the date when the time extension application is accepted as complete.
      2.   Approved Projects Not Yet Under Construction. Any approved development for which construction has not begun as of the effective date of these Regulations or any amendment may still be constructed as approved, as long as required building permits have been obtained before the expiration of any affected land use entitlement or, where applicable, before the expiration of any approved time extension. (See Chapter 19.30 - Permit Implementation, Time Limits, Extensions.)
      3.   Approved Land Uses Not Yet Established. Any approved land use that has not been established as of the effective date of these Regulations or any amendment may still be established in compliance with its approved permit, as long as establishment occurs before the expiration of the permit or, where applicable, before the expiration of any approved time extension. (See Chapter 19.30 - Permit Implementation, Time Limits, Extensions.)
      4.   Projects Under Construction. A structure that is being constructed under a valid building permit on the effective date of these Regulations or any amendment need not be changed to satisfy any new or different requirement of these Regulations.
   F.   Nuisance Prohibited. Nothing in these Regulations shall be construed to authorize the use of any real property for the creation or maintenance of a nuisance.
   G.   Other Requirements May Still Apply. Nothing in these Regulations eliminates the need for obtaining any other permits required by the City, or any permit, approval, or entitlement required by other provisions of the Municipal Code, or any regional, state, or federal agency.
   H.   Conflicting Permits and Licenses to be Void. All permits or licenses shall be issued by the City in compliance with the provisions of these Regulations, after the effective date of these Regulations or any applicable amendment. Any permit or license issued in conflict with these Regulations shall be void.
   I.   Conflicting Requirements:
      1.   Other Municipal Code Provisions. If conflicts occur between requirements of these Regulations, or between these Regulations and any other applicable statute, ordinance, rule, or other regulation of the City, the more restrictive shall apply.
      2.   Private Agreements. It is not intended that the requirements of these Regulations are to interfere with, repeal, abrogate, or annul any easement, covenant, or other agreement that existed when these Regulations became effective or were amended. These Regulations apply to all land uses and development regardless of whether it imposes a greater or lesser restriction on the development or use of structures or land than a private agreement or restriction. The City may not enforce any private covenant or agreement unless it is a party to the covenant or agreement.
