OGUC Accessibility Guide for Residential Buildings

What Is the OGUC?

The Ordenanza General de Urbanismo y Construcciones (OGUC) is Chile's primary regulatory framework governing the design, construction, and modification of buildings. It is issued under the Urban Planning and Construction Law and is administered by the Ministry of Housing and Urban Development (MINVU).

The OGUC contains specific chapters and articles addressing accessibility — the physical conditions that allow people of all abilities to access, use, and navigate buildings and their common areas. These provisions apply to both new construction and, in many respects, to existing buildings undergoing modifications or subject to compliance obligations.

Note: This page provides general informational context about OGUC accessibility requirements. It is not legal advice. The specific requirements that apply to any given building depend on its characteristics, construction date, and any modifications made. A professional assessment is the appropriate way to determine your building's specific obligations.

Key Areas

What OGUC Addresses for Residential Buildings

Accessible Routes of Travel

OGUC establishes requirements for accessible routes connecting building entrances to all common areas and facilities. These routes must be continuous, unobstructed, and meet specific dimensional requirements for width, surface material, and slope. Ramps are a key element, with specific requirements for gradient, landing dimensions, handrail specifications, and edge protection.

Corridor and Doorway Dimensions

Common corridors and doorways must meet minimum clear-width requirements to allow passage by wheelchair users and people using other mobility aids. These requirements specify both the minimum corridor width and the minimum clear width of doorways — which is measured differently from the nominal door width and often requires attention in older buildings where standard door sizes were narrower.

Vertical Circulation

For multi-story buildings, OGUC addresses requirements for elevators and other means of vertical access. This includes minimum cab dimensions, door width requirements, control panel heights and specifications, and signage requirements. In buildings where elevators were installed before current standards, modifications may be required to bring them into compliance.

Signage and Wayfinding

Accessible signage requirements address visual contrast, character size and font, mounting height, and the inclusion of tactile elements including braille. These requirements apply to signage identifying rooms, floors, exits, and hazards throughout common areas — essential for people with visual impairments to navigate independently and safely.

Accessible Sanitary Facilities

Common-area bathrooms must meet specific requirements for turning radius, grab bar placement and specifications, fixture mounting heights, door clearance and swing direction, and floor surface characteristics. These requirements ensure that people who use wheelchairs or other mobility aids can use shared bathroom facilities independently.

Accessible Parking

Buildings with parking areas must provide accessible parking spaces that meet specific dimensional requirements — wider than standard spaces to allow door opening and transfer. These spaces must be located close to accessible building entrances, clearly marked, and connected to the building by an accessible route. The required number depends on the total parking capacity.

Law 20.422 and the Right to Universal Access

Chile's Law 20.422, which establishes standards for equal opportunities and social inclusion for persons with disabilities, reinforces and complements the OGUC accessibility requirements. This law affirms the right of all persons to access the physical environment without barriers and establishes the principle of universal design as a guiding framework for built environments.

For building committees, Law 20.422 is relevant because it frames accessibility not merely as a technical building code requirement but as a matter of equal rights. This framing is increasingly reflected in how regulatory authorities approach compliance and how disputes related to building accessibility are resolved.

The Principle of Universal Design

Universal design refers to the design of environments, products, and communications that can be used by all people, to the greatest extent possible, without the need for adaptation or specialized design. In the context of residential buildings, universal design means common areas that are accessible to residents and visitors regardless of age, ability, or disability status.

This principle is relevant to building committees because it shifts the framing of accessibility from "accommodating people with disabilities" to "designing spaces that work for everyone" — which includes elderly residents, parents with strollers, people recovering from injuries, and many others who benefit from accessible design.

Phased Compliance in Existing Buildings

Both OGUC and Law 20.422 recognize that bringing existing buildings into full compliance with current accessibility standards may not be achievable immediately or without significant cost. The regulatory framework allows for phased compliance in existing buildings, provided that there is a documented plan for achieving compliance over time and that the most critical safety-related gaps are addressed as a priority.

This is the regulatory context in which our phased action plans operate — designed to be consistent with the phased compliance approach recognized by Chilean law, while providing the documentation that demonstrates good-faith progress toward full compliance.

Assessment Context

How OGUC Requirements Are Applied in Practice

Understanding how OGUC requirements are applied in practice — as opposed to how they read in the regulatory text — is one of the most valuable things an experienced accessibility assessor brings to the process.

The OGUC is a technical document written for professionals. Its requirements are expressed in technical language, reference other standards, and require interpretation in the context of specific building conditions. What reads as a straightforward requirement in the text may have significant practical implications for an older building with structural constraints.

Our assessors work from direct experience with how these requirements are interpreted and applied in the context of existing residential buildings in Chile. This practical knowledge — not just theoretical familiarity with the regulatory text — is what allows us to produce action plans that are genuinely implementable, not just technically correct on paper.
