Manufactured (HUD-Code) or Modular (IRC-CODE) - also referred to as Site-Built Code
A Broad Overview

We can and will build your home to either HUD (Manufactured) Code or IRC-Code (Modular). Please see our floor plan section for a better understanding.

You may have heard of each, but not know the difference between HUD code and IRC-Code. Let us give you a brief explanation

HUD Code -- (Manufactured Homes) A national "performance" code. This code preempts all local, county and state codes. After initial and final inspections at the factory, no additional inspections need to be made on the home itself, only a footing and final inspection for occupancy.

IRC-Code -- (Modular Homes) A "specific" code that needs to conform to state and local codes. Each home is modified to comply with specific state and local requirements. Multiple inspections are usually required during the construction phase as well as the installation stage. This is the code that all “site-built” homes are built to.

An example of a "performance" code vs. a "specific" code would be a rated 40 lb. Roof. HUD (performance) code simply states it requires a 40 lb. roof; construction technique is left to the builder. IRC-CODE (specific) specifies 2x6 engineered trusses every 16".

What does this mean to you?

Cost -- Due to the fact that each individual home needs specific engineered plans, multiple inspections, and somewhat different construction in order to comply with local codes, IRC-Code homes are $8 to $14 per square foot more expensive than HUD-Code homes.

CC&R’s -- Codes, Covenants and Restrictions (also called Restrictive Covenants). Typical of privately owned subdivisions. In certain instances only IRC-Code homes are accepted by developers in an attempt to limit manufactured housing in that area. In rare instances local conditions may require specific construction options that can not be accomplished with either HUD-Code or IRC-Code homes that are built off-site.

Construction -- Both HUD-Code and IRC-Code homes are built to perform the same function, but because they are different codes, one home may be built differently than another. For example, HUD-code homes are built with 2x6 floor joists on 16" centers, with twin metal I-beams supporting the floors under each section. IRC-Code homes have 2x10 floor joists and no supporting I-beams.

Time -- HUD homes take approximately 3 weeks to complete the factory construction process (initial planning, ordering, scheduling and building). IRC-Code homes take approximately 10 weeks to complete the same process. The actual building process takes the same for both. The other items take longer for IRC-Code homes than for HUD-Code Homes.
