A. Class of work defines and categorizes construction work on existing properties that is less than substantial rehabilitation. HUD has quoted language from the International Existing Building Code (IEBC) to define classes of work in the context only of this MAP Guide for the purpose of matching appropriate construction documentation and oversight to differing levels of work.[4] The levels of work defined from the least to the most significant in scope and complexity are as follows:
3 Given that the actual expenses spent from any contingency escrow or assurance of completion escrow will not be known until the end of construction, whether the level of work and the cost contemplated for the property are appropriate for 221(d)(4) Sub-rehab or 223(f) should be determined conservatively and not aggressively close to the cost threshold limit. The Lenders should take caution that at termination of the Repair Escrow when all the additional costs incurred during construction including change orders result in the final Aggregate Cost exceeding the Aggregate Cost Limit, the Lender will be subject to enforcement action by HUD.

Repair means “the reconstruction or renewal of any part of an existing building for the purpose of its maintenance or to correct damage.” [IEBC, Section 202 General Definitions] Repairs to site features (not buildings but otherwise similarly defined) are included in this class of work.
- “Repairs,….include the patching or restoration or replacement of damaged materials, elements, equipment or fixtures for the purpose of maintaining such existing components in good or sound condition with respect to existing loads or performance requirements.” [IEBC, Section 502.1]
Repairs also include related work, which is defined as “work on non-damaged components…necessary for the required repair of damaged components.” [IEBC Section 502.3]
In addition, installation of items not previously present in a building or on a site but necessary to address safety, security, accessibility or communications needs are considered “Repairs” when such installation and related work do not require alterations. Examples of such installation include but are not limited to 1) smoke detectors added to bedrooms; 2) signage or pavement markings added to identify accessible paths; 3) panic bars added to exit doors, etc.
Level 1 Alterations: “…include the removal and replacement or the covering of existing materials, elements, equipment, or fixtures using new materials, elements, equipment, or fixtures that serve the same purpose.” [IEBC Section 503.1]. Examples include removing and replacing an existing flooring or wall finish, etc.
Level 2 Alterations: “…include the reconfiguration of space, the addition or elimination of any [exterior] door or window, the reconfiguration or extension of any system, or the installation of any additional equipment.” [IEBC Section 504.1]
Examples include 1) adding or demolishing interior walls (partition or loadbearing) to reconfigure dwelling unit layout; 2) adding another bathroom inside a unit; 3) relocating the kitchen within a unit; 4) adding a new air conditioning system that was not previously present to the existing buildings and/or units; 5) adding an elevator to the building, etc.
- Level 3 Alterations: “…apply where the work area consisting of all reconfigured spaces exceeds 50% of the building area.” [IEBC Section 505.1]
