PDM de Viana do Castelo: zonamento e o que pode construir

O Plano Diretor Municipal de Viana do Castelo define onde e o que se pode construir no município. Esta página resume o zonamento da carta de uso do solo (CRUS), as condicionantes com expressão em Viana do Castelo e o que diz o regulamento do PDM, a partir dos dados analisados pelo Yonder.

Construir em Viana do Castelo: perguntas frequentes

Posso construir em terreno rústico em Viana do Castelo?

Cerca de 79% das parcelas classificadas na carta de uso do solo (CRUS) de Viana do Castelo estão em Solo Rústico. Em regra geral, o PDM restringe a edificação em solo rústico; a viabilidade depende da categoria de solo e das condicionantes aplicáveis. A resposta definitiva depende sempre da parcela concreta e do regulamento em vigor.

Que condicionantes afetam mais terrenos em Viana do Castelo?

Nos dados do Yonder para Viana do Castelo, as condicionantes com mais parcelas abrangidas são: Reserva Agrícola Nacional (RAN) (31 540 parcelas), Domínio hídrico e margens (6855 parcelas) e Rede Natura 2000 (6463 parcelas). Os números referem-se apenas às parcelas já avaliadas por camada.

O que diz o PDM

Classificação da áreaNatural/forest areas (producción, recreation and landscape enhancement, silvopastoral uses, hunting and fishing in inland waters); urban infill/continuity, transition and types I and II zones for housing, commerce, hospitality and equipment (with compatibility constraints); Industrial Zones (existing and proposed); Coastal Protection Area APC with specific prohibitions and APA oversight; urbanization-programmed zones; Rede Primária infrastructure zones (Nível 1 e 2) requiring on-site parking; environmental overlays (REN, RAN, Natura 2000); coastal non-aedificandi barriers; risk zones (erosion, floods, etc.).
Limite geral de alturaTypically ground floor + 1 floor (R/C + 1); maximum of 2 floors in some contexts; for block-type buildings up to 3 floors; exact limits depend on typology and Annex II of the PDM.
Pontos-chave
  • Observe REN, RAN and Natura 2000 regimes where applicable.
  • APC restrictions and need for binding APA opinions for coastal/APC projects; some forest-related actions must comply with PROF‑EDM and may require authorization.
  • Permits must note when lands lie in risk zones; projects in risk/barrier zones require favorable APA opinions.
  • Slope >30% areas are delimited and governed by special provisions.
  • Riparian protection strips and water margins require a minimum protected distance of 25 m (subject to edaphic conditions); coastal protection barriers are non-aedificandi and may be removed progressively where threatened by the sea.
Planos futuros
  • Plans of Detailed Planning (Planos de Pormenor) and Urban Operation Plans (UOPG), including PP1, PP2, UP3, UP8, etc., are planned/required; transitional regimes apply until approval (e.g., PPP1 limits buildability to conservation works).
  • Plans for expanding existing Industrial Zones (industrial/proposed zones) to accommodate growth.
  • Coastal APC areas require binding APA opinions; APC-related developments are subject to APA oversight and regulatory constraints.
  • Infrastructure planning including road/traffic studies for access to terminals, intermodal centers, warehouses, and industries when significant changes are proposed.
  • Municipal land concessions for green spaces and equipment within subdivisions/impact areas are regulated, with compensations if the concession area is under 500 m2.
NotasGeneral parameters (heights, setbacks, occupation and density) depend on space category defined in the Planning Map and Annex II; exact values for heights, COS, indices and setbacks are in the Regulation and Annexes. Annexes count toward the construction index; maximum annex area is 25 m2 per dwelling/unit. Parking and access rules vary by use: e.g., minimum parking ratios (1 space per dwelling/unit; for commerce/services 1 space per 50 m2; industry around 10 m2 per 100 m2 or alternate rules such as 1 light vehicle per 120 m2 or 1 heavy per 500 m2); Type II zones specify 3 parking spaces per 2 dwellings and 1 space per 50 m2 of commerce/services. Conditional buildability applies in many areas pending approved PP/UOPG; required studies include context/urban studies and traffic studies; binding APA opinions apply in coastal/APC areas and for certain forestry activities under PROF‑EDM. Municipal land concessions for green spaces/equipment are regulated with possible compensation if the ceded area is small (under 500 m2).
