New York, Washington County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Washington County Building & Safety Division

The Building & Safety Division of Washington County, Oregon, serves as the Authority Having Jurisdiction (AHJ) for building permits and inspections. They are responsible for ensuring that construction and renovation projects comply with state and local building codes for safety and structural integrity. This includes reviewing plans, issuing permits, and conducting inspections throughout the construction process.

Permit Requirements for Unincorporated Areas

Properties located in unincorporated areas of Washington County are subject to the same building permit requirements as those within incorporated cities. The Building & Safety Division oversees all construction and remodeling activities in these areas to ensure compliance with the Oregon Structural Specialty Code (OSSC) and other relevant regulations.

Demolition Work Permit Triggers

Demolition work during a remodel in Washington County typically requires a permit. Specific triggers for demolition permits include:

Any work that involves the removal of structural elements.
Demolition of any building or portion thereof, regardless of size, if it is part of a larger renovation project.
Projects involving the removal of hazardous materials, such as asbestos or lead paint, which often necessitate specialized permits and procedures.

It is advisable to contact the Building & Safety Division directly to determine the exact permit requirements for your specific demolition scope.

Permits for Converting Non-Living Spaces

Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas in Washington County requires a building permit. This process is considered a significant alteration and involves ensuring the space meets all code requirements for:

Habitability: This includes proper insulation, ventilation, egress (windows and doors), and structural support.
Electrical and Plumbing: New or modified electrical wiring and plumbing systems must be installed to code.
Fire Safety: Compliance with fire-resistance ratings for walls, ceilings, and doors is essential.

The definition of "habitable space" generally refers to areas intended for sleeping, living, or cooking. Therefore, any conversion that results in such a space will trigger the need for a permit and subsequent inspections.

New York Remodeler Legislation, Codes, and Guidelines

New York State Building Codes for Remodelers and Residential Renovations

New York State's building codes are primarily governed by the Uniform Fire Prevention and Building Code (Uniform Code) and the State Energy Conservation Construction Code (Energy Code), which are incorporated into Title 19 of the New York Codes, Rules and Regulations (19 NYCRR). These codes are based on model codes published by the International Code Council (ICC), with New York State modifications. The 2020 edition of the Uniform Code, for example, includes amendments related to energy storage systems. As of early 2025, New York State was proposing to adopt the 2024 versions of the International Code Council's model codes, including the 2024 Residential Code of New York State and the 2024 Building Code of New York State.

It is important to note that New York City is permitted to retain its own building code, which is enforced by the NYC Department of Buildings (DOB) and the Department of Housing Preservation and Development (HPD).

Primary State Boards and Agencies

The State Fire Prevention and Building Code Council is statutorily responsible for developing and maintaining the Uniform Code and the Energy Code. The New York State Department of State's Division of Building Standards and Codes (DBSC) serves as the secretariat to the Code Council, administers statutory functions, and evaluates proposed changes to the codes. The DBSC also provides technical support and ensures the health, safety, and resilience of the built environment across New York State.

For New York City, the NYC Department of Buildings (DOB) is the primary agency responsible for enforcing building codes and issuing permits for renovation and alteration projects.

Classification of Remodels and Demolition Guidelines

Generally, the New York State Uniform Code and its incorporated International Codes differentiate between cosmetic renovations and structural alterations. Cosmetic upgrades, such as painting or refinishing floors, typically do not require permits. However, projects involving structural changes, alterations to the building's layout, plumbing, electrical systems, or changes in occupancy classification generally require permits and must comply with the code.

Converting attics or basements to habitable living spaces, moving or altering walls (structural or non-structural), and significant plumbing or electrical work are considered structural alterations and necessitate adherence to building codes and permit requirements.

Demolition guidelines are also in place to ensure safety. Before demolition begins, hazardous materials like asbestos must be surveyed and removed by licensed contractors. Utilities must be shut off and capped. Demolition sites require proper safety zones, barricades, and dust control measures. The specific requirements for demolition, including safety zones, can vary based on the scope of work and whether mechanical demolition equipment is used.
