(1) Privately owned buildings and improvements for residential purposes; improvements to a single-family residential property which is also used as a place of business, which are required in order to operate the business, need not be considered to be rehabilitation of a commercial or industrial building, if the improvements also provide general benefit to the residential occupants of the building;

(2) Low-income public housing and other publicly owned residential buildings and improvements;

(3) Publicly or privately owned commercial or industrial buildings, except that the rehabilitation of such buildings owned by a private for-profit business is limited to improvement to the exterior of the building, abatement of asbestos hazards, lead-based paint hazard evaluation and reduction, and the correction of code violations;

(4) Nonprofit-owned nonresidential buildings and improvements not eligible under § 570.201(c); and

(5) Manufactured housing when such housing constitutes part of the community's permanent housing stock.

(3) Loans for refinancing existing indebtedness secured by a property being rehabilitated with CDBG funds if such financing is determined by the recipient to be necessary or appropriate to achieve the locality's community development objectives;

(5) Improvements to increase the efficient use of water through such means as water savings faucets and shower heads and repair of water leaks;

(6) Connection of residential structures to water distribution lines or local sewer collection lines;

(7) For rehabilitation carried out with CDBG funds, costs of:

(c) Code enforcement. Costs incurred for inspection for code violations and enforcement of codes (e.g., salaries and related expenses of code enforcement inspectors and legal proceedings, but not including the cost of correcting the violations) in deteriorating or deteriorated areas when such enforcement together with public or private improvements, rehabilitation, or services to be provided may be expected to arrest the decline of the area.

(d) Historic preservation. CDBG funds may be used for the rehabilitation, preservation or restoration of historic properties, whether publicly or privately owned. Historic properties are those sites or structures that are either listed in or eligible to be listed in the National Register of Historic Places, listed in a State or local inventory of historic places, or designated as a State or local landmark or historic district by appropriate law or ordinance. Historic preservation, however, is not authorized for buildings for the general conduct of government.

Any substantial rehabilitation, as substantial rehabilitation is defined by 24 CFR 5.100, of a building with more than 4 rental units, for which CDBG funds are first obligated by the recipient on or after April 19, 2017, must include installation of broadband infrastructure, as this term is also defined in 24 CFR 5.100, except where the recipient determines and, in accordance with § 570.506, documents the determination that:

(1) The location of the substantial rehabilitation makes installation of broadband infrastructure infeasible;

(2) The cost of installing broadband infrastructure would result in a fundamental alteration in the nature of its program or activity or in an undue financial burden; or

(3) The structure of the housing to be substantially rehabilitated makes installation of broadband infrastructure infeasible.
