Permanent Preservation Area (APP): what it is, what the protected strips are and what can you do inside one?
Permanent Preservation Area: the 30 to 500 m strips, the 50 m radius around springs, what is allowed and fines of up to R$ 50,000/ha. A practical guide.
A Permanent Preservation Area (APP) is an area protected by the Brazilian Forest Code (Law 12,651/2012), whether or not covered by native vegetation, whose function is to preserve water resources, the landscape, biodiversity and soil stability. The most common strips: 30 to 500 meters along rivers (depending on their width) and a 50-meter radius around springs. Building or clearing vegetation in an APP, outside the legal exceptions, leads to an embargo, fines and the obligation to restore the area.
The land is yours, the deed is registered, the property tax is paid — and you may still be barred from building on that strip beside the stream. Owners find this out the hard way: with the construction embargo, the environmental infraction report and the order to demolish what took years of savings. The APP is one of the most misunderstood limits on property rights in Brazil — and one of the most expensive to ignore.
A Permanent Preservation Area is an area protected by law because of its environmental function — preserving rivers and springs, holding slopes in place, sheltering biodiversity — regardless of whether there is any vegetation on it today (art. 3, II, of Law 12,651/2012). The detail that changes everything: the protection comes from the location, not the registry; no “clean” property record (matrícula) erases an APP. In this article, we will show where APPs exist, what is allowed inside them, the regime for areas already occupied and the consequences of violations.
Where do APPs exist — and how big are they?
Article 4 of the Brazilian Forest Code establishes the main cases. The table summarizes the general strips along natural perennial and intermittent watercourses, excluding ephemeral ones, measured from the regular channel’s edge. Springs and water sources also include intermittent ones under the STF’s interpretation in ADC 42 and related cases:
| Situation | APP strip |
|---|---|
| Watercourse less than 10 m wide | 30 m on each bank |
| River 10 to 50 m wide | 50 m |
| River 50 to 200 m wide | 100 m |
| River 200 to 600 m wide | 200 m |
| River more than 600 m wide | 500 m |
| Springs and water sources, including intermittent ones | 50 m radius |
| Slopes | gradient steeper than 45° |
| Hilltops and restingas/mangroves | according to the criteria of art. 4 |
Protection applies in urban and rural areas. For consolidated urban areas, art. 4, §10 provides for different strips under municipal or Federal District legislation, subject to environmental and disaster-risk safeguards. Local law and applicable court decisions must be checked; existing buildings neither eliminate an APP nor allow an owner to reduce it unilaterally.
What are you allowed to do inside an APP?
The rule is to preserve vegetation. Intervention or removal requires a statutory ground of public utility, social interest or low environmental impact (arts. 3, VIII–X, and 8), with authorization where required. Stricter conditions protect vegetation around springs, dunes and restingas; specific exceptions also exist, including certain urgent civil-defense works. Article 9 permits access for water and low-impact activities. The competence of CETESB or another agency must be checked in São Paulo, and the legal basis and required procedures documented before intervention.
What about areas that were already occupied? The “consolidated areas” regime
For farming, forestry, livestock, ecotourism and rural tourism activities in rural areas consolidated by July 22, 2008, art. 61-A provides conditional continuation and differentiated restoration. Along watercourses, restoration strips are 5, 8 or 15 meters for properties up to four fiscal modules, depending on the size category; above that threshold, the environmental regularization program (PRA) specifies 20 to 100 meters. The area and circumstances at the statutory date, CAR registration, soil conservation and other requirements must be checked. CAR and PRA do not authorize new intervention or automatically reduce the APP: these rules concern restoration of eligible existing occupation.
What happens to those who build or clear vegetation in an APP?
Consequences can arise on three fronts: administrative, with stop-work orders and fines — art. 43 of Decree 6.514/2008 sets R$ 5,000 to R$ 50,000 per hectare or fraction for the conduct it defines, not a single tariff for all building works; civil, with repair, restoration and possible demolition as appropriate; and criminal, when an offense’s elements are established, such as art. 38 of Law 9.605/1998. STF Theme 999 concerns the absence of a limitation period for civil environmental repair claims, not every fine or criminal proceeding. Environmental liabilities may affect price and negotiations, depending on the property.
A hypothetical example: Mr. Joaquim’s smallholding in Ibiúna
Imagine Mr. Joaquim buying an 8-hectare smallholding in Ibiúna crossed by a 4-meter-wide natural stream, with a general 30-meter strip on each bank. If pasture has existed since the 1990s, fiscal modules, the property’s configuration at the statutory date, CAR and agency requirements must be checked before specifying restoration. Fences and native planting may form part of a technical plan, without a promise of completion in two years. A new kiosk built in 2023 does not automatically benefit from the old rural use and may attract sanctions if unlawful. This is a fictional example, not a firm case outcome.
The most common (and costly) mistakes
- Trusting that a “clean” property record (matrícula) authorizes building. An APP need not appear as an encumbrance in the registry. Risk: embargo and demolition of a project licensed only on municipal paper.
- Buying rural property without reviewing the CAR and the environmental liabilities. Risk: inheriting the obligation to restore — it follows the property without releasing the person responsible for the damage.
- “Clearing” the riverbank to make the land more valuable. Risk: a fine per hectare, an environmental crime and the obligation to replant.
- Intervening first and asking for authorization later. Risk: facing sanctions, without an automatic right to regularize the later intervention.
An actionable checklist before buying or building near water
- Identify watercourses, springs and slopes on the property (and on the immediate neighbors’ land);
- Measure the strips of art. 4 from the regular channel — with a topographic survey, not “by eye”;
- For rural property: check the CAR, the occupation date (before/after July 22, 2008) and the declared liabilities;
- Before any intervention: check whether the case fits public utility, social interest or low impact, and obtain the environmental agency’s authorization;
- When buying: deduct from the price (or require the seller to resolve) any restoration liability.
Frequently asked questions
What counts as a Permanent Preservation Area?
It is an area protected under art. 3, II of Law 12.651/2012 for its environmental functions, whether vegetated or not. General strips of 30–500 m apply to natural perennial or intermittent watercourses, and a 50 m radius to springs and water sources, including intermittent ones under the STF’s interpretation. Slopes and other locations defined in art. 4 are also protected. Urban and rural areas are covered, subject to special rules and technical delimitation.
Can I build in an APP on my own land?
As a rule, no. Intervention requires a legal ground of public utility, social interest or low impact and the procedures required by the competent agency. Specific conditions, restrictions and authorization exceptions must be checked before work starts. Private ownership does not waive environmental protection; unlawful works may lead to stop-work orders, fines, restoration and possible demolition.
What is the fine for clearing or building in an APP?
Article 43 of Decree 6.514/2008 sets a fine of R$ 5,000–50,000 per hectare or fraction for specified conduct affecting APP vegetation. Other offenses have their own criteria, and work may be halted. Civil repair and criminal liability are assessed separately. STF Theme 999 removes the limitation period for civil environmental repair claims, not for all sanctions.
I bought a property with an APP degraded by the previous owner: is the obligation mine?
The civil restoration obligation may be enforced against the current owner or possessor even for earlier damage because it attaches to the property (STJ Theme 1204). This neither releases the polluter nor automatically transfers personal fines. The STJ excludes a former owner whose right ended before the damage and who did not contribute to it. CAR, liabilities and enforcement notices should be reviewed before purchase.
When should I see a lawyer about APP issues in São Paulo?
Before buying land with a watercourse or beginning work near a river, stream or spring, and promptly after a notice or stop-work order. Counsel coordinates technical delimitation, checks agency competence, possible exceptions and consolidated-area rules, and examines enforcement grounds, deadlines and restoration plans. Authorization or the lowest cost cannot be guaranteed.
An APP restricts use without itself changing property boundaries
Treating the strip along the stream as “the back of the yard” is the origin of embargoes, fines and demolitions that no deed can prevent. Those who map the APPs before buying or building turn the restriction into a design input — and environmental liabilities into a negotiated discount.
