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
3 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
base_districts[*].mh_zoning_siting_authority_status | override | no_state_preemption_local_control | Alabama has no broad statute preempting municipal zoning of manufactured housing. Cities may exclude MH from single-family districts, require HUD-Code compliance, foundation/skirting, or limit MH to designated districts. |
base_districts[*].mh_taxation_classification_basis | override | ala_code_40_12_255 | §40-12-255 governs MH taxation/registration only (real-property ad valorem on owner-occupied land; annual registration decal on rented land) — not zoning. |
base_districts[*].mh_construction_standards_basis | override | federal_hud_code_24_cfr_3280_plus_alabama_mh_commission_anchoring | Federal HUD Code (24 CFR Part 3280) preempts construction standards; Alabama Manufactured Housing Commission and Title 24 anchoring rules govern installation safety. Local zoning controls siting only. |

Research notes
Tracked as explicit non-preemption for clarity. Federal HUD Code preempts construction standards (federal_conflict_check on), but state has not preempted municipal zoning of where MH may be sited. Cities routinely restrict MH to designated MH-park districts or require design-equivalence with site-built housing. Industry-blog claims of a 2024 Alabama STR-style MH preemption could not be confirmed against ALISON; treat any such citation as unverified.
