City of Asheville's Standard Specifications and Details Manual
The purpose of the City of Asheville's Standard Specifications and Details Manual is to provide a resource that establishes development requirements that protects the public health, safety, and welfare through the provision and maintenance of public or private infrastructure improvements related to developing, redeveloping, and subdividing land, as well as providing necessary rights-of-way, transportation, and utility services. The City of Asheville has composed an updated edition of the Standard Specifications and Details Manual that was adopted by City Council on May 13, 2014.

Before installing your sign or awning on your business please check the requirements -- it could save you valuable time and money. Not all signs require Plan Review -- if the sign is smaller than those listed on the checklist a Code Enforcement Officer can assist you in the field. Most sign installation requires a permit, please contact the Development Services Center at (828) 259-5846 before installation.
What you need to know before building an attached or free-standing deck to your home.
Dryer Duct Detail of Fire Resistance Rated Assembly
North Carolina Building Codes and North Carolina Mechanical Codes permit a metal dryer duct to penetrate a rated floor ceiling assembly. In an effort to clarify an often considered "gray area" in the code, a descriptive detail has been prepared. The common confusion comes from the fact that both the Mechanical Code and the Building Code require compliance. The wording, which allows this installation, is not found in any single location of either code.
Along with this detail, additional methods of dryer venting may be used, including providing a soffit below the rated assembly and running the dryer duct within the soffit, or providing a rated shaft within the floor system for the duct to be installed. For more information please contact Development Services at (828) 259-5846.
The North Carolina 2006 State Building Code lists particular requirements for handrails, specifically for the graspability. To assist with questions, the City offers a visual interpretation for your convenience.
Unvented Gas Heaters
Housing Code Section 4-210(g)1(a) – Mechanical/Heat – allows the use of unvented natural gas heaters having oxygen depletion sensors listed for residential use by UL, ETL, or other North Carolina recognized testing laboratory and installed in strict accordance with the manufacturer’s instructions as the primary source of heat.
The State Building Code (2006 N.C. Fuel Gas Code, Section 621.2) will no longer allow unvented natural gas heaters to be installed as the primary source of heat in a dwelling unit. New installations of unvented room heaters must comply with current code and all replacement installations must meet code requirements under which they are installed.
The use of unvented fuel-burning heaters is prohibited in any bedroom.
