A construction boundary touching a neighbouring household’s land is the site dispute most prone to escalation: excavation encroaching by a few dozen centimetres, vibration cracking the house next door, and residents blocking the site gate. This article handles three layers — encroachment, property damage and prevention through surveying and boundary marking — within construction activity, unlike pure land-boundary disputes between land users (EXP-6054) and general land-boundary disputes (EXP-2377): here one side is a live construction project and damage accrues in real time.
Construction encroaching onto residents’ land: the handling sequence
On discovering encroachment, first stop the works at the disputed location and verify the boundary using the cadastral file, the land allocation or lease decision and the extract survey map, against the physical boundary under the rules on boundaries between immovable properties in Article 175 of the Civil Code 91/2015/QH13 and boundary markers in Article 176 of that code. If the survey shows the project is within its boundary, the survey record signed by the neighbouring household and the commune authority is the shield against later complaints. If encroachment is real, the project must restore the boundary or agree compensation and lease or purchase of the affected land through proper land procedures. As to dispute sequence, the Land Law 31/2024/QH15 requires self-mediation or mediation at the commune people’s committee where the land lies before court suit for a pure land dispute; the property-damage claim can be separated and resolved through ordinary civil procedure.
Damage to residents’ houses: compensation and the condition survey
Vibration from excavation and pile driving cracking neighbouring houses is the most common scenario. Non-contractual compensation liability arises on the general basis in Article 584 of the Civil Code 91/2015/QH13 where construction activity damages another’s property; compensation covers restoration cost or the value of the damaged part, actual lost income and reasonable loss-prevention costs. The decisive point in every case is causation: cracks caused by construction or pre-existing cracks, and the evidence answering that question is the pre-construction condition survey of neighbouring houses, with detailed photographs of every old crack. A project that skips the condition survey falls into a weak position: unable to prove the house was already cracked, it can hardly resist a claim for full compensation. Where the parties disagree, an independent construction survey of the damage cause is the necessary step before court.
When residents block construction, and the prevention equation
Residents blocking the gate and hanging banners is a common reaction when a compensation claim goes unanswered. Legally, unlawful obstruction of construction may be administratively handled, but calling in enforcement without parallel negotiation rarely resolves the root, because the household’s compensation right remains and the case easily escalates into a collective petition to the province. The wise sequence is: the commune authority records the event and mediates immediately; the project suspends the contentious work front but maintains unrelated works; and a written compensation timeline is offered. Prevention from the start comprises three things that cannot be skipped: boundary surveying and marking confirmed by the neighbouring household before site fencing; a condition survey of surrounding houses within the vibration influence radius; and notice of the construction plan with a complaint contact point for the neighbourhood. These take a few days, while a construction-boundary dispute lasting several months is entirely normal.
Frequently Asked Questions
How to handle construction encroaching onto residents’ land?
First stop the encroaching work, record the site status with the commune authority and the household present, and re-check the boundary against the cadastral file and the land allocation decision. If encroachment is real, agree boundary restoration or compensation and adjusted land use; a land dispute must go through mediation at the commune people’s committee under the Land Law 31/2024/QH15 before suit, unless the parties choose arbitration by agreement.
How to compensate for damage to residents’ houses?
Compensation covers repair or rebuilding costs for the damaged part based on a causation survey, property losses and income lost during repair. Article 584 of the Civil Code 91/2015/QH13 sets the general basis of non-contractual liability; the pre-construction condition survey of neighbouring houses is the decisive evidence separating construction-caused damage from pre-existing damage.
Residents block the construction?
Nobody may lawfully obstruct by force, but blocking the gate and holding equipment escalates the case and may draw administrative handling. The right response is to have the commune people’s committee record the event and mediate on the spot, suspend only the disputed work front while keeping others running, and put the household’s compensation claim into a written negotiation track instead of physical confrontation.
Surveying and boundary marking before construction?
It is close to mandatory in risk terms: survey and fix the boundary under Article 175 of the Civil Code 91/2015/QH13 on boundaries between immovable properties, set markers with the neighbouring household’s signed confirmation, and survey and photograph the condition of surrounding houses before excavation. The cost of this step is trivial next to the cost of one encroachment or cracked-house dispute.
