In short
The Puerto Rican Institute of Culture’s Built Historic Heritage Program issues the recommendations the Permit Management Office and autonomous municipalities need before authorizing work on historic properties, historic zones or sites, and eligible properties. Since Ley 161-2009 and the Joint Regulation, the Institute moved from Endorsing Agency to Recommending Agency in cases filed with OGPe, but remains a regulatory agency under other statutes and regulations. What surprises people is the reach: there are over 8,175 identified historic-value structures, 12 historic zones designated by the Planning Board, and on top of that the recreation plazas of all 78 municipalities with the properties in their perimeter blocks, and buildings zoned “P” or Public built before 1960, whether or not in a historic zone. The list of actions requiring a recommendation includes things nobody expects: applying exterior paint, installing awnings, signage, major cleaning, pruning or planting trees in public spaces, and mobile businesses. Billboards and murals are not permitted in historic sites or zones.
What is it?
The Program protects Puerto Rico’s built historic heritage, which includes every building of heritage and cultural value designated by the Planning Board on the Institute’s recommendation, those listed in the US Department of the Interior’s National Register of Historic Places, those on UNESCO’s World Heritage List, and Eligible properties, public and private, certified by the Institute. Its legal basis is Ley Núm. 89 of 21 June 1955, the Institute’s Organic Act, whose Section 4 imposes the duty to conserve, restore and study movable and immovable property of historic value and to advise the Planning Board. Ley Núm. 119 of 26 September 2005 authorized it to impose fines for violating or failing to comply with the regulations it administers. And La Fortaleza and the Old San Juan Historic District are part of UNESCO’s world heritage.
Who can do it?
This is where many people discover they are inside it. The Institute issues recommendations on properties officially designated and included in the Planning Board’s Register of Historic Sites and Zones, in the National Register of Historic Places, those classified as CRH, SH or R-ZH surrounding recreation plazas, those of architectural value, and Eligible ones under the criteria of the Joint Regulation, Volume XI, Chapter 51. Statewide there are over 8,175 identified historic-value structures; some 255 are in the Planning Board’s Register and some 335 in the National Register, plus the 12 designated historic zones. To those are added the recreation plazas of all 78 municipalities and the properties in their perimeter blocks, as well as buildings zoned “P” or Public built before 1960, whether or not in historic zones: former school buildings, city halls, former courthouses, former police stations, former fire stations, cemeteries, hospitals and jails. The application is made by the owners or an authorized professional.

Step by step
Step 1: Find out whether your property is inside
Do not assume it is not. Beyond the 12 designated historic zones and the properties on the state and national registers, it takes in the recreation plazas of all 78 municipalities and the properties in the perimeter blocks around those plazas, and buildings zoned “P” or Public built before 1960, whether or not in a historic zone. The Institute itself issues Historic Value Certifications precisely to confirm whether a property is within the limits of a historic zone or has been designated a Historic Site, and what its historic value is. Any person or entity can request one.
Step 2: Check whether what you plan is on the list
The Institute issues recommendations for: partial demolition; total demolition; new construction, restoration, remodelling and major or substantial intervention; construction of temporary structures, infrastructure, planting or fences; minor intervention; intervention in public spaces — infrastructure, signage, furniture, fountains, sculptures, pruning, removing or planting trees; intervention in recreation plazas; use of 1,999 square feet or less; use of 2,000 square feet or more; installing permanent or temporary signs or advertisements; installing awnings or curtains; name change on a tax exemption certification; applying exterior paint; major cleaning; relocating structures; subdividing or grouping lots; mobile business; and alcoholic beverage sales. If your job is painting the façade, yes, it is on the list.
Step 3: Three things that are simply not permitted
The Institute says it without qualification. Large billboards and pylons are not permitted in historic sites or zones. Murals are not permitted in historic sites and zones. And in the San Juan Historic Zone, alcoholic beverage sales cannot be the sole or principal activity of new businesses; any such recommendation is additionally subject to the location requirements of Subtitle E, Chapter 5, of the Internal Revenue Code, especially sections 5050.10 to 5050.12.
Step 4: Submit the service request
The ICP publishes a PPHE Service Request form that comes combined with the invoice and evidence of payment, which tells you the procedure has a cost even though the page publishes no amount. The application is made by the owner or an authorized professional. If your case goes through OGPe, the Institute acts there as a Recommending Agency since Ley 161-2009; if it goes through an autonomous municipality, the recommendation is issued to that municipality too. Some items — signage, awnings and major cleaning — are filed through OGPe when combined with a Use Permit.
Step 5: If you restored: the tax exemption
Ley Núm. 7 of 4 March 1955, the Historic Sites and Zones Tax Incentives Act, allows owners of properties in historic zones and sites who have restored, rehabilitated or conserved them wholly or partly to obtain certifications for tax exemption benefits. Ley 187-2015 added a requirement worth handling before you leave the house: the Department of Treasury asks that every Compliance Certification request be duly sworn before a notary. And in the Municipality of San Juan, the Historic Value Certification is issued to reduce the amount payable in construction excise taxes, but in those cases its issuance requires the Institute’s favourable recommendation or endorsement prior to the works.
Step 6: Ask for advice before buying or before breaking ground
Among the functions the Program publishes is advising and guiding on best intervention practices anyone interested in acquiring, or already owning, a property within a historic zone or site or an eligible property. It also issues Advisory opinions: when asked to evaluate a property’s potential for restoration, conservation or rehabilitation, it responds setting out the parameters under which works would be carried out, according to the property’s style, its condition, the materials and construction methods used and the historic and proposed uses. Asking first costs nothing; finding out afterwards is expensive.

How long it takes
What to do if something goes wrong
If your property faces your town’s recreation plaza, check before touching anything: the plazas of all 78 municipalities and the properties in their perimeter blocks are within the Program’s reach. If the building is zoned “P” or Public and was built before 1960, so is it, whether or not in a historic zone. If you already did the work without a recommendation, bear in mind that Ley 119-2005 authorized the Institute to impose fines for violating or failing to comply with the regulations it administers. If your filing is combined with a Use Permit, signage, awnings and major cleaning are filed through OGPe. This guide does not say what the application costs or how long the recommendation takes: the ICP publishes a form that includes an invoice and evidence of payment, but publishes neither the amount nor a term, and PRFácil does not invent them. Nor does it reproduce the intervention criteria of the Joint Regulation, Volume XI, Chapter 51, which is where the technical rules of what is and is not allowed live. PRFácil gives no legal or architectural advice.
Common mistakes
- Believing “historic zone” means only Old San Juan.
- Painting the façade without a recommendation: applying exterior paint is on the list.
- Putting up a sign, an awning or a curtain without going through the Institute.
- Pruning or planting a tree in a public space of a historic zone without a recommendation.
- Painting a mural in a historic zone, where they are not permitted.
- Installing a billboard or pylon in a historic site or zone, where they are not permitted.
- Bringing the Compliance Certification request without swearing it before a notary.
- Doing the work first and asking afterwards for the Historic Value Certification for the San Juan excise discount: the prior favourable recommendation is needed.
Frequently asked questions
Do I need permission to paint my house?
If the property is in a historic zone or site or is eligible, yes: “Applying Exterior Paint” appears expressly on the list of actions for which the Institute issues recommendations.
How do I know if my property is in a historic zone?
The Institute issues Historic Value Certifications precisely for that: they confirm whether a property lies within the limits of a Historic Zone or has been designated a Historic Site by the Planning Board, along with its historic value. Any person or entity can request one.
My house faces the town plaza. Does it count?
The Institute expressly includes the recreation plazas of all 78 municipalities and the properties in their perimeter blocks within the Program’s reach, along with buildings zoned “P” or Public built before 1960, whether or not in historic zones.
Can I paint a mural?
Not in historic sites and zones. The Institute says it literally: murals are not permitted in historic sites and zones. Large billboards and pylons are not either.
Is there a tax benefit for restoring?
Yes. Under Ley Núm. 7 of 4 March 1955, owners of properties in historic zones and sites who have restored, rehabilitated or conserved them wholly or partly can obtain certifications for tax exemption benefits. Since Ley 187-2015, Treasury asks that the Compliance Certification request be sworn before a notary.
