Trigger predicate
When this evaluates true for a parcel, the law's preempted fields take precedence over base zoning.
project.use_type == manufactured_home_hud_codePreempted fields
4 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
jurisdiction.manufactured_home_total_exclusion | waive | — | A local government may not exclude HUD-code manufactured homes from the entire jurisdiction; MH must be permitted in at least one zoning district. |
base_districts[*].manufactured_home_appearance_standards | cap_at | site_built_standards_same_district | §6-29-1145: appearance/compatibility standards (roof pitch, siding, skirting, min width, min square footage) on HUD-code MH may not be more restrictive than those imposed on site-built homes in the same district. |
base_districts[category=res_sf].allowed_uses | add | modular_home | §27-1-60: modular homes (factory-built to the SC Residential Code) are single-family dwellings for zoning purposes and must be permitted wherever site-built SF is permitted, with no additional permitting beyond what applies to site-built. |
base_districts[*].mh_construction_standards | waive | — | Federal HUD Code (24 CFR Part 3280, NMHCSSA 1974) preempts state and local construction standards for HUD-code units; §31-17-320 / §31-17-330 set uniform statewide installation standards that further preempt stricter local installation rules. |

Research notes
Two-tier preemption: federal HUD Code controls construction; state §6-29-1145 enforces zoning parity. Pre-HUD-code mobile homes (built before June 15, 1976) are NOT protected and may be excluded outright. Local governments retain authority to designate which districts permit MH and to enforce parity-level (not stricter) appearance standards. Modular homes (§27-1-60) carry stronger protection — any ordinance requiring separate or stricter permitting for modular is preempted.
