Code Requirements for Calfornia Handrails and Guardrails
When referring to handrail code requirements it’s important to initially establish the differences between handrails and guardrails. Handrail is a term most often used within stairway railings and angled applications like ADA ramps where a graspable “handrail” is required. Guardrails more often refer to level rail applications and “barrier” railing applications.
Residential stairway handrail requirements state that handrails are required on at least one side of stairways with four or more risers. Handrail height must be set between 34 and 38 inches measured vertically from the sloped plane of the stair tread nosing or finished surface of a ramp. Residential applications refer to group one private residences, single family use cases.
When is a handrail not required?
Stairways with fewer than 4 risers do not require handrails in residential applications. Deck surfaces that are less than 30″ in height above natural grade do not require guardrails; however if any railings are installed they must meet current code requirements.
Lateral Force and/or Loading Requirements
Handrails must be able to withstand a minimum force of 200 pounds applied in any direction at any point along the top rail. During a handrail inspection; the building inspector may select a point on the railing midspan and push or lean outwards to measure the lateral loading ability of the railing frame. He will also inspect the height of the railing at different locations to ensure uniformity and establish that the entire railing falls within code compliant height requirements. Installers and DIYer’s alike should keep this in mind when calculating post and top rail spans, vertical picket spacing and horizontal cable tensioning. Sturdy rails = easy inspections and code compliance.
How do I figure out my railing height?
Railing height should be measured from the top of the deck surface to the top of the railing cap member. A good rule of thumb is to measure from multiple locations to ensure uniformity across the surface. Decks and patios can vary, especially when dealing with slopes so it’s best to check height in multiple locations.
Commercial Handrail Code Requirements
Commercial handrail code is a bit more stringent than that of residential applications. Most notably, commercial stairways require handrails on both sides of the stairs and both sides of ramps in commercial buildings. The entire differences between residential and commercial code can be found HERE.
Commercial stairs and ramps will be subjected to constant traffic in public settings and people of all ages and sizes. Examples of commercial railing applications : parks, restaurants, hospitals, office buildings, warehouses, docks, and piers.
Products and Services for Safer Handrails
Many people choose to hire a stairway contractor or railing professional to guarantee handrail code requirements are safely met. Selecting a vendor like S.D.C.R. that is versed in California building codes and hiring a licensed contractor can help satisfy any code requirements. For low level rails and non commercial applications our DIY products and solutions are very popular and effective ways to easily construct cable railings with professional results.
High rise multi unit complexes, HOA’s, and municipalities are often required to use professional contractors for construction projects. Additionally, insurance claims often require the use of a professional.
