Signs in a residential zone: twelve feet for the office, thirty-two for the "For sale"

In short

Rule 8.7.5 of Joint Regulation No. 9473 begins by closing the door: signs are not permitted in the residential district, except where a commercial, industrial, tourist, institutional, service or public use has been approved for the premises or property, in which case the norms relating to advertisements apply. And it adds two conditions: the approval of those permits is processed by the same route by which the Permiso Único was authorised, and they are not permitted if the Permiso Único is of a domiciliary or accessory character. That said, the following section lists seven signs that are permitted, each with its measure. Those identifying professional offices or home occupations, barbershops or beauty salons permitted as accessory uses: no more than twelve square feet, without lighting, affixed to the front wall and parallel to the road. Those identifying uses permitted in residential districts: up to thirty-two square feet with non-intermittent lighting, and where the affixed sign is not effective it is permitted on the ground at no more than ten feet of height. Real estate sale or rental ones: up to thirty-two square feet without lighting, one per property, and on a vacant lot on the ground up to twenty feet of height. Those for hotels and tourist hotels: up to thirty-five per cent of the area of any façade, plus another on the ground of up to four hundred square feet and fifty feet of height. Those for commercial activities permitted in R-U and R-T: up to twenty-five per cent of the area of the premises’ façade, including doors, windows and display cases. Identification ones for residential developments or apartment houses: up to thirty-two square feet without lighting, and on the ground up to twenty feet of height. And those for commercial, institutional and service activities in R-U or unzoned areas: up to twenty-five per cent of the façade, and if the building stands back from the road, on the ground up to twenty-four square feet and twenty feet of height.

What is it?

It is Rule 8.7.5 of Chapter 8.7 of Joint Regulation No. 9473, the one governing signs in residential districts. It has two sections: one of general provisions, setting the starting rule — signs are not permitted save where a use is approved — and how the permit is processed; and another listing the seven types of sign that are permitted, with their size in square feet, their maximum height where they go on the ground, and whether they may carry lighting or not.

Who can do it?

The rule applies to signs in residential districts. Signs are not permitted in the district, except where a commercial, industrial, tourist, institutional, service or public use has been approved for the premises or property, in which case the norms relating to advertisements apply; and they are not permitted if the Permiso Único is of a domiciliary or accessory character. Signs for professional offices or home occupations, barbershops or beauty salons apply to those permitted as accessory uses. Those for commercial activities under paragraph (e) apply to those permitted in R-U and R-T Districts. And those under paragraph (g) apply to commercial, institutional and service activities permitted in R-U District or in unzoned areas.

Step by step

Step 1: The starting rule: not permitted
The general provisions section says it plainly: signs are not permitted in this district, except where a commercial, industrial, tourist, institutional, service or public use has been approved for the premises or property, in which case the norms relating to advertisements apply. That is, the door opens through the approved use, not through the sign. And it adds two procedural conditions: the approval of these permits is processed by the same route by which the Permiso Único was authorised, and they are not permitted if the Permiso Único is of a domiciliary or accessory character.
Step 2: How many signs and facing where
The same section sets the count: more than one sign is permitted on the building’s or premises’ façades and one on the ground where it is permitted, and in both sitings they are installed parallel or perpendicular to the public road. The exception is this chapter’s usual one: except where the façade faces a National Highway System road.
Step 3: Twelve feet for the home office
The first of the seven permitted signs is the smallest and the one most people need. Signs identifying professional offices or home occupations, barbershops or beauty salons permitted as accessory uses, not exceeding twelve square feet in size, without lighting, affixed to the wall constituting the building’s front, parallel to the public road. That is four conditions at once: the size, the absence of lighting, the front wall, and the parallel orientation.
Step 4: Thirty-two feet for the permitted uses
The second covers signs identifying the uses permitted in residential districts, with a list of exclusions: it does not cover hotels, tourist hotels, commercial activities permitted in R-U and RT districts, nor commercial, institutional and service activities in R-I and R-U Districts or in undeveloped areas. Those it does cover shall not exceed thirty-two square feet, with non-intermittent lighting, fixed to the building’s front façade parallel to the public road. And it brings the practical outlet: where the affixed sign is not effective for identifying the activity, its siting on the ground at a height no greater than ten feet is permitted, parallel or perpendicular to the public road.
Step 5: The "For sale" and "To let"
Real estate sale or rental signs, on any of the building’s façades, not exceeding thirty-two square feet in size, without lighting. One sign per property to be sold or rented is permitted, and it must be placed affixed to the building’s wall parallel or perpendicular to the road. And for land without a house: on a vacant lot a ground sign may be installed, within the property, with a height from ground level to its highest part no greater than twenty feet and an area no greater than thirty-two square feet, parallel or perpendicular to the road.
Step 6: Hotels: thirty-five per cent and fifty feet
Identification signs for hotels and tourist hotels are the rule’s most generous. They shall not exceed thirty-five per cent of the area of any of the building’s façades in size, with or without non-intermittent lighting, affixed to the building parallel or perpendicular to the road. And another sign of a maximum size of four hundred square feet may be sited on the ground, parallel or perpendicular to the public road, identifying the hotel and its activities; that one shall have a height from ground level to its highest part no greater than fifty feet.
Step 7: The twenty-five per cent that includes the display cases
For commercial activities permitted in R-U and R-T Districts, the signs shall not exceed twenty-five per cent of the area of any of the façades of the premises they are to identify, including doors, windows and display cases. That last precision matters: the façade area on which the twenty-five per cent is computed includes the openings, not only the wall. It may have non-intermittent lighting and shall be affixed to the building parallel or perpendicular to the road.
Step 8: The development and the building set back from the road
Identification signs for residential developments or apartment houses shall not exceed thirty-two square feet in size, without lighting, affixed to any of the building’s façades or on the ground; the ground sign shall have a height no greater than twenty feet. And the last paragraph covers commercial, institutional and service activities permitted in R-U District or in unzoned areas, which shall not exceed twenty-five per cent of the area of any of the façades as determined by this chapter; where the building or structure stands back from the public road and the sign fixed to the façade is not effective for identifying the activity, its siting on the ground is permitted, not exceeding twenty-four square feet in size and at a height no greater than twenty feet, parallel or perpendicular to the public road.
Step 9: Two notes on the source
The permitted-uses paragraph excludes from its own scope the commercial, institutional and service activities in R-I and R-U Districts, while the last paragraph governs those same activities only in R-U District, naming no R-I; the text does not say which paragraph covers such an activity in an R-I district, and we do not decide it. Separately, two paragraphs use the labels "R-T" and "RT" as a district code, and that label appears nowhere else in this chapter. We reproduce both as printed.

Where to do it

The sign permit is processed by the same route by which the premises’ or property’s Permiso Único was authorised, before OGPe or the municipality of the corresponding hierarchy. If the Permiso Único is of a domiciliary or accessory character, the rule does not permit the sign. And where the sign corresponds to a commercial, industrial, tourist, institutional, service or public use approved in a residential district, the rule itself refers to the norms relating to advertisements, which are in another rule of the chapter.

What to do if something goes wrong

The question to answer first is not how big the sign is but what use is approved at the premises. In a residential district signs are not permitted, and the exception comes in through the approved commercial, industrial, tourist, institutional, service or public use; if the Permiso Único is domiciliary or accessory, there is no sign. With that answered, find the corresponding paragraph and take its exact measure, because each is different: twelve square feet without lighting for the professional office or beauty salon as an accessory use; thirty-two with non-intermittent lighting for permitted uses generally; thirty-two without lighting for the "For sale"; twenty-five per cent of the façade for commerce in R-U and R-T; and thirty-five per cent plus a four-hundred-square-foot ground sign for hotels. Two details change the calculation: in commerce’s twenty-five per cent, the façade area includes doors, windows and display cases; and in several paragraphs the ground sign is permitted only where the affixed one is not effective or the building stands back from the road, with height caps of their own — ten, twenty or fifty feet as the case may be. And if the façade faces a National Highway System road, there is no sign.

Common mistakes

Installing a sign in a residential district without a commercial, industrial, tourist, institutional, service or public use having been approved for the premises.
Installing a sign where the Permiso Único is of a domiciliary or accessory character, in which case the rule does not permit it.
Processing the sign permit by a route other than the one by which the Permiso Único was authorised.
Exceeding twelve square feet, or adding lighting, on a professional office, barbershop or beauty salon sign permitted as an accessory use.
Adding lighting to the real estate sale or rental sign, or installing more than one per property.
Installing the "For sale" sign on the ground on a lot with a building, when the rule permits it on the ground on vacant lots.
Exceeding twenty feet of height on the ground sign of a vacant lot or of a residential development.
Computing the twenty-five per cent of a commercial premises’ façade without including doors, windows and display cases.
Exceeding four hundred square feet or fifty feet of height on a hotel’s ground sign.
Placing a permitted use’s sign on the ground without the affixed sign having proved ineffective for identifying the activity.
Exceeding ten feet of height on that ground sign, or twenty-four square feet and twenty feet of height on that of a building set back from the road.
Installing a sign where the façade faces a National Highway System road.

Frequently asked questions

Can I put a sign at my house if I work from there?

Signs identifying professional offices or home occupations, barbershops or beauty salons permitted as accessory uses are allowed, not exceeding twelve square feet in size, without lighting, affixed to the wall constituting the building’s front and parallel to the public road. That said: the general rule says signs are not permitted if the Permiso Único is of a domiciliary or accessory character, so check which permit you hold before installing.

How big can a "For sale" sign be?

No more than thirty-two square feet, without lighting, one per property to be sold or rented, affixed to the building’s wall parallel or perpendicular to the road. On a vacant lot it may be installed on the ground, within the property, with a height no greater than twenty feet and an area no greater than thirty-two square feet.

What sign may a hotel have in a residential district?

An affixed one not exceeding thirty-five per cent of the area of any of the building’s façades, with or without non-intermittent lighting. And another sign may be sited on the ground of a maximum size of four hundred square feet identifying the hotel and its activities, with a height no greater than fifty feet.

Are display cases included when computing the façade area?

In signs for commercial activities permitted in R-U and R-T Districts, yes: the twenty-five per cent is computed on the area of any of the façades of the premises the sign is to identify, including doors, windows and display cases.

Can I put the sign on the ground instead of on the wall?

Only in the cases the rule provides for. For permitted uses, where the affixed sign is not effective for identifying the activity, it is permitted on the ground at a height no greater than ten feet. For commercial, institutional and service activities in R-U or unzoned areas, where the building stands back from the public road and the affixed sign is not effective, it is permitted on the ground not exceeding twenty-four square feet and at a height no greater than twenty feet.
