In short
Chapter 5.1 of the Joint Regulation decides whether you can carve lots out of a property and on what conditions. It starts with nine prohibitions: land in Specially Protected Rustic Soil, land of historic or cultural importance, land requiring preservation of its flora or fauna, land susceptible to flooding, landslides or storm surge, land whose topographic features have special meaning for the community, land inside the coastal zone, land forming part of a Territorial Ordination Plan that does not permit it, land incompatible with agricultural zones, and land whose direct access is through thirteen arterial roads named one by one, shall not be processed as lotificaciones. Those cases go through a Consulta de Ubicación. Then come the shape rules: side boundaries as far as possible perpendicular to the access, average depth not exceeding three times the width, and a remnant that may not be smaller than the lot you are forming. For urbanisation via exception — the simplified route — the minimum area is 600 square metres where there is no sanitary sewer, and the three-segregation count runs on the parcel as it existed on 29 June 1964, counting the remnant as one of them. And a rule that saves many old cases: de facto lotificaciones that already existed on 4 September 1944 may be considered with other requirements dispensed with.
What is it?
It is Chapter 5.1 of Joint Regulation No. 9473, titled Urbanisations and Subdivisions. Its purpose, per the text itself, is to establish the guidelines and the closest coordination between the developer and the entities responsible for the infrastructure the proposed use needs, from the earliest stages of processing, to ensure the project internalises the infrastructure provision costs inherent to its operation without affecting the quality or quantity of service available to the community or sector. In practical terms: it is the chapter governing splitting land into lots. This guide covers the general provisions, the processing and urbanisation via exception. Roads and easements, and neighbourhood facilities, have separate guides on this site.
Who can do it?
It applies to anyone proposing to subdivide or urbanise land in Puerto Rico. Urbanisation projects are filed with an Autonomous Municipality under the Convenio and the Territorial Ordination Plan; where there is no Territorial Ordination Plan or the corresponding delegations have not been transferred, they are filed before OGPe. There are nine cases that are not processed as lotificaciones and must be filed through a Consulta de Ubicación. And there are two routes with different requirements: ordinary lotificación or urbanización, and urbanisation via exception, whose express purpose is to reduce and simplify the procedures and minimum requirements needed to evaluate them. There is also a long list of exempt transactions for government entities concerned — ACT and DTOP, AAA, AEE and AFI, the Agriculture Department, ATPR, ATPR with Housing, PRIDCO, the Ports Authority, and the National Parks Company with the DRNA — each with its own conditions.

Step by step
Step 1: First, rule out the nine prohibitions
Proposals on land that: sits in Specially Protected Rustic Soil; is of importance to historic or cultural heritage; requires preservation of its flora or fauna for economic, ecological or scientific importance; is susceptible to flooding, landslides or storm surge, or sits on landslide deposits per the USGS geological quadrangles or on land with a landslide history; is an area whose topographic features or vegetation have special meaning for the community; sits inside the coastal zone as defined in the Coastal Zone Management Plan; has direct access through the arterial roads PR-1, PR-2, PR-3, PR-10, PR-17, PR-18, PR-20, PR-22, PR-26, PR-30, PR-52, PR-53 and PR-66; forms part of a Territorial Ordination Plan that does not permit it; or is incompatible with the use of agricultural zones and existing agri-livestock projects — shall not be processed as lotificaciones. Cases affected by these provisions must be filed through a Consulta de Ubicación. It is not that they are forbidden: they go through another, longer door.
Step 2: Look at the lot’s shape before drawing it
Section 5.1.2.4 sets three short rules that decide many projects. The new lots’ side boundaries shall, as far as possible, be perpendicular to the access. The lot’s average depth shall not exceed three times its width. And any lot to be left as a remnant may not have an area smaller than that of the lot being formed. That last one surprises people: you cannot keep the little corner and sell someone else the big piece. On sizes, Section 5.1.2.5 adds that where the lotificación is proposed inside a qualified area the areas adjust to the district they sit in, and that the subdivision of fractions smaller than the minimums may be authorised to be added to another lot, provided the lot or remnant it is reduced from still complies.
Step 3: Check the access and the road plans
No permit for the lotificación of lots or holdings shall be issued unless the lot has the corresponding public or private access. And there is a priority rule worth checking before buying: where roads proposed in the road plans crossing the property are included in the Highways and Transportation Authority’s Five-Year Road Construction Programme, or have been programmed for construction by the municipal authorities, they prevail and no lotificación shall be authorised within their proposed right of way. Where construction of those roads has not been programmed, lotificación and the necessary works are permitted without regard to their occupying land identified for those roads.
Step 4: If it is an urbanisation, there is a geotechnical study
For every urbanisation project, including urbanisations via exception, landslide risk and other subsoil conditions are taken into account through a geotechnical study certified by a licensed engineer. The study evaluates the land’s geology and hydrology, the presence of geological faults, the area’s landslide history, the land’s susceptibility to them, topography, the presence of landslide deposit materials as described in the USGS geological quadrangles of Puerto Rico, and the subsoil’s engineering properties, among others. And it must establish the measures that will be taken to reduce liquefaction effects, the siting of structures on sinkhole-susceptible land, reduce settlement and avoid landslides.
Step 5: Urbanisation via exception and the count from 1964
The purpose of distinguishing urbanisations via exception from lotificaciones is to reduce and simplify the procedures and minimum requirements needed to evaluate them. On areas: if proposed in non-qualified areas or in qualification districts setting no specific minimum areas but permitting segregation, the minimum areas will be 600 square metres where there is no sanitary sewer, and the alternate used-water system provisions and Chapter 9.7 on control of access to public roads must be complied with. If the proposed areas are under 600 metres, or the parcel is classified as Specially Protected Rustic Soil, a Consulta de Ubicación must be filed. And here comes the count that changes many people’s plans: to comply with the requirement of not exceeding three lots to be formed, every segregation in the parcel as it existed on 29 June 1964, the effective date of Act No. 116 of 1964, counts as one of the three segregations, bearing in mind that the remnant constitutes a segregation. That is: what was segregated sixty years ago counts, and so does the piece you keep.
Step 6: De facto lotificaciones: the door for old cases
Section 5.1.1.4 resolves many tangled titles. OGPe or the hierarchy I-III Autonomous Municipality may consider segregation applications where it is shown they already existed on 4 September 1944 and have access to a public road; or where it can be evidenced that the land is physically segregated by public roads duly registered as public use and ceded to the municipality or corresponding entity, or by any other natural element such as rivers or streams, and has access to a public road. In those cases compliance with other requirements of the Regulation or of the municipality’s Ordination Regulation is dispensed with, as applicable. The key word is "may": it is not automatic, and it has to be proven.
Step 7: The plano de inscripción governs
No building shall be built, no land disposed of in any way, and no permit issued for land use or buildings, until the corresponding Plano de Inscripción has been approved. The regulation recognises two exceptions. In urbanisations, construction of the structures may be authorised together with the urbanisation works without the planos de inscripción having been authorised. And in lotificaciones resulting from reparcelación, a limitation on use or disposition may be imposed even after the Plano de Inscripción is approved, until the urbanisation works needed for the uses contemplated in the Territorial Plan or in this Regulation are built and accepted.
Step 8: Leasing is not always subdividing
Section 5.1.1.5 expressly dispenses lease contracts that do not constitute a lotificación of the parcel or of a structure from applying for lotificación permits and the corresponding plano de inscripción, in two cases: projects that by their nature and complexity require the siting of more than one structure on the same parcel, being functionally related to the same principal purpose; and projects that on occasion require lease contracts over a portion of the parcel or of a structure for the siting of a particular use or client. It is the rule that allows, for instance, leasing a space inside a building without having to segregate it.
Step 9: The remnant and the infrastructure
Where a parcel of land is not proposed in its entirety for development, additional infrastructure capacity shall be provided, with duly dedicated public or private access, within the remnant, to supply the needs a development similar to the one proposed would generate there if the whole remnant were inside urban soil. But if the remnant is outside urban soil, or if the requested segregation completes the lotificación, providing additional infrastructure capacity for future developments is not permitted. It is the regulation’s way of preventing capacity from being installed for a development nobody has evaluated.
Where to do it
Urbanisation projects are filed with an Autonomous Municipality under the Convenio and the Territorial Ordination Plan. Where there is no Territorial Ordination Plan or the corresponding delegations have not been transferred, urbanisation projects are filed before OGPe under this Regulation. De facto lotificaciones may be considered by OGPe or the hierarchy I-III Autonomous Municipality. And cases falling under any of the nine prohibitions are filed through a Consulta de Ubicación.
How long it takes
What to do if something goes wrong
The costliest mistake is drawing the lots before reading the prohibitions. If your land falls under any of the nine cases in Section 5.1.2.3 — and the seventh, direct access through PR-1, PR-2, PR-3, PR-10, PR-17, PR-18, PR-20, PR-22, PR-26, PR-30, PR-52, PR-53 or PR-66, catches many people — the case is not processed as a lotificación and must go through a Consulta de Ubicación. The second mistake is the count: for urbanisation via exception, the three segregations are counted on the parcel as it existed on 29 June 1964, and the remnant counts as one. If your grandfather already segregated twice, you have one left. The third is shape: average depth may not exceed three times the width, and the remnant may not be smaller than the lot you form. The fourth is sequence: without an approved plano de inscripción nothing is built, no land is disposed of and no permit is issued, save the two exceptions the regulation names. And if your case is an old one, look at Section 5.1.1.4 before giving up: lotificaciones that already existed on 4 September 1944, with access to a public road, may be considered with other requirements dispensed with. Five caveats. First: we publish no cost or processing time; the chapter fixes no fee and estimates no duration. Second: we did not read the Coastal Zone Management Plan, the USGS geological quadrangles, Act No. 116 of 1964, the Land Act or its Title V, Chapter 9.7, the Consulta de Ubicación chapter, the qualification districts of Chapter 6.1 or the Territorial Ordination Plans; we name them because the chapter sends readers to them. Third: the list of exempt transactions in Section 5.1.2.7 is long and very agency-specific; we summarise its principal numbers and do not reproduce it whole. Fourth, on source defects: Section 5.1.5.2 is headed "Prohibitions" and its paragraph (c) is a loose line about municipalities in a metropolitan statistical area with fifty thousand inhabitants or more, without saying what is prohibited in them; and in Section 5.1.2.7 the list under ACT and DTOP jumps from b) to d), leaving a paragraph without its letter. We reproduce both as printed and do not resolve them. Fifth: this same chapter’s roads, easements and grading, and the neighbourhood facilities, have separate guides on this site. And a note on the link: the file the Board publishes is named "Reglamento Conjunto de Emergencia", but the document inside is Joint Regulation No. 9473 of 16 June 2023.
Common mistakes
- Drawing the lots before checking the nine prohibitions in Section 5.1.2.3.
- Not checking whether direct access is through one of the thirteen arterial roads the regulation names.
- Counting only recent segregations: the count of three runs from the parcel as it existed on 29 June 1964.
- Forgetting that the remnant counts as one of the three segregations.
- Leaving a remnant with a smaller area than the lot being formed.
- Projecting lots with a depth greater than three times their width.
- Building or selling before the Plano de Inscripción is approved.
- Assuming 600 square metres where the qualified district sets a different area: in a qualified area the district governs.
Frequently asked questions
How many lots can I segregate?
For urbanisation via exception, the regulation refers to the requirement of not exceeding three lots to be formed, and explains how they are counted: every segregation in the parcel as it existed on 29 June 1964, the effective date of Act No. 116 of 1964, counts as one of the three segregations, bearing in mind that the remnant constitutes a segregation. Outside that route, areas and numbers depend on the qualification district the land sits in.
Why was I sent to a Consulta de Ubicación?
Because the land falls under one of the nine cases in Section 5.1.2.3, which are not processed as lotificaciones: Specially Protected Rustic Soil, historic or cultural importance, preservation of flora or fauna, susceptibility to flooding, landslides or storm surge, topographic features with special meaning for the community, coastal zone, direct access through thirteen named arterial roads, a Territorial Ordination Plan that does not permit it, or incompatibility with agricultural zones and agri-livestock projects. Urbanisation via exception also goes through a Consulta de Ubicación where the proposed areas are under 600 square metres or the parcel is Specially Protected Rustic Soil.
What is the minimum lot area?
It depends. Where a lotificación is proposed inside a qualified area, the proposed areas adjust to the district they sit in. In urbanisation via exception in non-qualified areas, or in districts setting no specific minimum areas but permitting segregation, the minimum is 600 square metres where there is no sanitary sewer. And in several of the exempt transactions in Section 5.1.2.7 the regulation sets 350 square metres for parcels in rustic soils and in urban-soil communities, and 400 square metres with sewer or 600 without for bona fide agregado lots.
Can I segregate if the access is a main road?
Proposals on land whose direct access is through the following arterial roads shall not be processed as lotificaciones: PR-1, PR-2, PR-3, PR-10, PR-17, PR-18, PR-20, PR-22, PR-26, PR-30, PR-52, PR-53 and PR-66. Those cases must be filed through a Consulta de Ubicación.
What is a de facto lotificación?
It is the segregation that already existed physically before permits were required. OGPe or the hierarchy I-III autonomous municipality may consider segregation applications where it is shown they already existed on 4 September 1944 and have access to a public road, or that they are physically segregated by public roads duly registered as public use and ceded to the municipality or corresponding entity, or by any other natural element such as rivers or streams, and have access to a public road, with other requirements dispensed with.
Do I need a subdivision permit to lease part of my property?
The regulation dispenses lease contracts that do not constitute a lotificación of the parcel or of a structure from applying for subdivision permits and the corresponding plano de inscripción, in two cases: projects that by their nature and complexity require more than one structure on the same parcel, functionally related to the same principal purpose, and projects requiring a lease over a portion of the parcel or of a structure for the siting of a particular use or client.
Can I build before the plano de inscripción is approved?
The general rule is no: no building shall be built, no land disposed of in any way, and no permit issued for land use or buildings, until the corresponding Plano de Inscripción has been approved. The exception is in urbanisations, where construction of the structures may be authorised together with the urbanisation works without the planos de inscripción having been authorised.
