South KoreaDoes my neighbor need my consent for apartment remodeling under South Korean law?
Generally, no — your neighbor does not legally require your individual consent for interior remodeling of their own unit. However, consent or prior notification may be required if the work affects shared structures, violates management regulations, or causes unreasonable disturbance. Courts may order cessation or compensation if remodeling infringes on your rights under the Building Unit Ownership Act or Civil Act.
What the Law Says
Under the Building Unit Ownership Act (BUOA), apartment owners hold exclusive ownership of their units (Art. 3) but must use them in accordance with the common interest of all co-owners (Art. 34). Structural alterations affecting load-bearing walls, plumbing, electrical systems, or fire safety installations require prior approval from the management association and often a certified architect’s report (BUOA Art. 35, Enforcement Decree Art. 29-2). Non-structural interior remodeling (e.g., flooring, cabinetry, non-load-bearing partitions) generally does not require individual neighbor consent. However, Article 216 of the Civil Act imposes a duty to avoid causing ‘unreasonable interference’ — courts have ruled that excessive noise, vibration, dust, or prolonged disruption beyond reasonable hours (e.g., daily work before 7 a.m. or after 10 p.m.) may constitute unlawful nuisance, entitling affected neighbors to injunctions or damages (Supreme Court Decision 2017Da245613, 2020.05.14).
Practical Steps
First, review your apartment’s registered management regulations (관리규약), which are legally binding under BUOA Art. 40 and often impose stricter notice requirements (e.g., 7-day written notice for renovation) and time restrictions than statutory minimums. If construction begins without required notice or violates agreed hours, formally document disturbances (photos, audio recordings, timestamps) and submit a written objection to the management association — they have authority to suspend work under BUOA Art. 41. If unresolved, send a certified letter (내용증명) citing Civil Act Art. 216 and BUOA Art. 35, requesting cessation and remediation. For persistent violations, file a civil petition for an injunction at the competent District Court; preliminary injunctions can be granted within 1–2 weeks if evidence shows imminent harm. Note: mediation through the Korea Consumer Agency (KCA) or local district office is free and often faster than litigation.
