Summary
Rio Rancho prohibits converting a home's private garage to living space unless the homeowner builds a replacement garage: every dwelling unit must keep an attached or detached garage under the city's design standards.
These overhang, roof pitch and private garage requirements shall not apply to any dwelling unit, building or structure constructed or installed prior to December 23, 1999. Notwithstanding the above, conversions of preexisting or post-December 23, 1999, private garages are prohibited unless another private garage is constructed to replace the converted private garage.
(4) Each single-family dwelling unit shall have exterior siding and roofing which, in color, materials and appearance, are comparable to the predominant materials in use on surrounding dwelling units, or, if there is no predominance, are similar to the exterior siding and roofing material commonly in use on residential dwelling units in the community as a whole.
(5) All dwelling units must face the address street or create a presence on the address street. Street presence can be created by including elements such as windows, site walls, gates, portals, courtyards and landscaping in the architectural design or site plan.
(6) All front steps necessary for access due to a difference in grade between the front door and/or the floor of the dwelling unit and finished grade shall be permanently installed and shall be constructed of stone, concrete or masonry materials.
(7) An all-weather driveway shall be constructed from the property line to the private garage or carport, or to any other area designated for off-street parking in accordance with Section 154.76.

Full Breakdown
City Code's residential design standards require every dwelling unit to have an attached or detached private garage sized to park automobiles or light trucks, finished to match the house, and completed within 12 months of occupancy. Converting an existing private garage, whether built before or after December 23, 1999, into living space or any other non-garage use is prohibited unless the homeowner constructs another private garage to replace it. Only the roof-pitch and overhang design standards in the same subsection exempt structures built before December 23, 1999; the garage-replacement requirement applies regardless of when the garage was built.
Violations & Fines
Converting a private garage to living space without building a replacement garage violates § 154.60(A)(3)(c) and can be cited by Code Enforcement, requiring restoration of usable garage space or construction of a new one.
