Reading

Acquisition, demolition and rehabilitation all touch the people already living in the building, and CDBG carries two separate layers of protection for them. 24 CFR 570.606 points a grantee to the first layer, the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970, implemented at 49 CFR Part 24 and usually just called the URA. The second layer, section 104(d) at 24 CFR Part 42 Subpart C, only turns on when lower-income housing is being demolished or converted away from lower-income use, and it adds an obligation the URA does not carry on its own: replacing the housing that was lost, not just compensating the person who lost it. Both layers can apply to the same project at the same time, and a grantee that only thinks about one of them has not finished the analysis.

The replacement window under Section 104(d) A timeline showing that when a project triggers the one-for-one replacement rule under Section 104(d), replacement lower-income units must first be made available within a window that opens one year before the recipient makes its replacement information public and closes three years after demolition or rehabilitation begins. The recipient must make the location and schedule of the replacement units public before it commits funds, and the units must stay lower-income for 10 years. Window opens 1 year before replacement information is made public Window closes 3 years after demolition or rehabilitation begins Section 104(d) one-for-one replacement · units then stay lower-income for 10 years after first occupancy
Replacement units must first become available within a window that opens one year before the recipient makes its replacement information public and closes three years after demolition or rehabilitation begins, and the location and schedule must be public before funds are committed.

Who counts as a displaced person under the URA

A displaced person is someone who moves from real property permanently and involuntarily as a direct result of rehabilitation, demolition or acquisition for an assisted activity. That core definition (570.606(b)(2)) also reaches further than the obvious case of someone whose home is torn down. A permanent move counts when it follows a notice to move permanently for the assisted activity, and it can count even earlier if the grantee or HUD decides the project directly caused it. A tenant is also displaced when not given a reasonable opportunity to lease a suitable unit in the same building at an affordable rent after the project, or when required to relocate temporarily without an offer to pay all reasonable out-of-pocket expenses (or under unreasonable conditions) and then not returning. A person evicted for cause, for serious or repeated lease violations, is not counted unless the eviction was meant to evade relocation duties. The reason the definition reaches this far is that a person can lose their housing just as completely through a move a grantee never pays for as through outright demolition, and the URA does not let a grantee avoid its obligations by choosing which path a displacement takes.

A grantee may adopt an optional relocation policy that goes beyond what the URA itself requires. If it does, that policy must be written, made public, and applied equally within each class of displaced persons. An optional policy is a one-way ratchet: a grantee can promise more than the federal floor, but once it does, it has to deliver that promise consistently rather than case by case.

Section 104(d) and the one-for-one replacement rule

Section 104(d) is triggered when occupied and vacant occupiable lower-income dwelling units are demolished or converted to a use other than lower-income housing in connection with an assisted activity. When that happens, those units must be replaced, unit for unit, with comparable lower-income units. The HUD field office can excuse replacement only when objective data show an adequate supply of vacant lower-income units in standard condition in the area (42.375(d)). A lower-income dwelling unit for this purpose is one where the market rent, including utilities, does not exceed the applicable Fair Market Rent for existing housing under 24 CFR Part 888. This is a rent test, not an occupant income test, so whether a particular unit counts depends on what the unit itself would rent for, not on how much the person living in it happens to earn.

The reason this rule exists is straightforward: federal money should not be the tool that shrinks the supply of lower-income housing in a community it is supposed to be helping. Demolishing an occupied low-rent unit with CDBG funds and walking away leaves that community with one fewer affordable home than it had before the grant arrived. One-for-one replacement is the mechanism that keeps the CDBG program from working against its own purpose.

The replacement window

Replacement units have to become available within a specific window: it runs from one year before the recipient makes public its required replacement information (the activity, the units lost, and the location and schedule of replacement units, 42.375(c)), to three years after the demolition or rehabilitation actually begins. Put together, that is a window of at least four years, longer if work starts after the disclosure. The window is not measured only from the day demolition starts. It deliberately reaches backward to capture replacement housing that a grantee may have already lined up before the public even learned a demolition was coming, as well as forward to give the grantee time to build or acquire replacement units after the work begins.

Within that window, the replacement units themselves have to meet several conditions. They must be:

  • within the recipient's jurisdiction
  • in standard condition, or raised to standard from substandard if no one was displaced from the unit and it was vacant for at least three months
  • sufficient in number and size for the original occupants
  • kept as lower-income units for at least 10 years from initial occupancy

That last condition, the 10-year affordability period, is what turns one-for-one replacement from a one-time construction obligation into a decade-long commitment. A grantee has not satisfied section 104(d) just by building or acquiring a replacement unit. It has to keep that unit as lower-income housing for ten years after someone first moves in, which means the obligation is still open long after the replacement unit itself is finished and occupied, and often long after the underlying CDBG grant has otherwise closed out.

The Residential Antidisplacement and Relocation Assistance Plan

A recipient must certify that it has adopted, and follows, a Residential Antidisplacement and Relocation Assistance Plan (a unit of local government funded by the State certifies to the State, 42.325). That plan has to set out how the recipient will minimize displacement, provide relocation assistance under 42.350, and supply the replacement units section 104(d) requires. This certification is not a formality signed once and filed away. It is the document a grantee is supposed to actually be following at the moment a demolition or conversion decision gets made, and the plan has to already address relocation and replacement before the displacement happens, not after.

The choice belongs to the displaced person

Where both the URA and section 104(d) apply to the same displaced person, that person has a choice to make, and it is their choice, not the grantee's. A displaced lower-income person may elect either URA assistance under 49 CFR Part 24, or section 104(d) benefits: advisory services, moving expenses, security deposits, interim housing costs, and replacement housing assistance delivered as either rental assistance or cooperative purchase assistance. A grantee cannot decide on the person's behalf which package is better for them, and cannot steer someone toward the package that happens to be cheaper or easier for the grantee to administer. The grantee's job is to explain both options accurately and let the displaced person pick.

What this means in practice for GCHS

Most single-family rehabilitation at GCHS does not involve demolition, so section 104(d) will not be triggered on the majority of projects. But the moment a project does involve demolishing or converting an occupied or vacant occupiable lower-income unit, even a single unit, the one-for-one replacement obligation attaches, and it attaches at unit count one, not at some minimum project size. That makes the first practical step on any demolition-involved project the same one every time: determine, and document, whether the structure being demolished is a lower-income dwelling unit under the Fair Market Rent test, before any demolition decision is made. If it is, the replacement window and the ten-year affordability period both key off events tied to that decision, and a Residential Antidisplacement and Relocation Assistance Plan needs to already be in place, not drafted afterward.

Temporary relocation deserves the same attention even on projects that never touch demolition. A tenant who has to move out for the duration of rehab work can become a displaced person under 570.606(b)(2) if no one offers to pay the reasonable out-of-pocket costs of the move and the tenant does not return, so a rehab program that quietly expects people to find their own temporary housing during construction, without covering the cost, can create displaced persons under the URA without realizing it. Plan and budget for temporary relocation costs on every such project. And on any project where a displaced person qualifies for both URA and section 104(d) benefits, GCHS staff should present both options clearly and let the person choose, keeping the choice, and the explanation given, documented in the file. That single habit, letting the person choose and writing down that they did, is what turns a decade-long compliance obligation into a manageable one.

Practice questions

1. What federal act, implemented at 49 CFR Part 24, does 24 CFR 570.606 point to for relocation assistance to displaced persons?

  1. The Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970
  2. The Housing and Community Development Act of 1974
  3. The Fair Housing Act
  4. The Residential Antidisplacement and Relocation Assistance Plan required under 24 CFR Part 42 Subpart C

2. A GCHS rehab project requires a tenant to move out of the property temporarily during construction. GCHS does not offer to pay the tenant's reasonable out-of-pocket costs for the move, and the tenant does not return to the building. Is the tenant a displaced person under the definition in this lesson?

  1. No, because temporary relocation is never covered by the URA regardless of reimbursement or return
  2. Yes, because a tenant moved temporarily without an offer to pay reasonable costs, who does not return, is treated as displaced
  3. No, because only permanent, involuntary moves as a direct result of demolition count as displacement, and rehabilitation never displaces anyone
  4. Yes, but only if the temporary relocation exceeds a fixed dollar amount specified in 570.606

3. GCHS wants to offer relocation benefits more generous than the URA requires. What must be true of that policy for it to be valid?

  1. It only needs internal board approval and does not need to be made public
  2. It may be applied selectively, case by case, based on each displaced person's individual circumstances
  3. It must be written, public, and applied equally within each class of displaced persons
  4. It is not permitted; grantees may not offer relocation benefits beyond what the URA itself requires

4. What triggers the section 104(d) one-for-one replacement requirement under 24 CFR Part 42 Subpart C?

  1. Any demolition of residential property regardless of the rent level or occupancy status of the units involved
  2. Acquisition of real property for a CDBG-assisted activity, regardless of whether any structure is demolished
  3. Rehabilitation of a lower-income dwelling unit that does not involve demolition or conversion
  4. Demolition or conversion to a use other than lower-income housing of occupied and vacant occupiable lower-income dwelling units

5. How does this lesson define a lower-income dwelling unit for purposes of the section 104(d) one-for-one replacement rule?

  1. A unit whose market rent, including utilities, does not exceed the Fair Market Rent under 24 CFR Part 888
  2. A unit occupied by a household whose income falls below the area's low and moderate income limit on the date demolition is announced
  3. A unit located in a census tract where at least 51 percent of residents are low and moderate income
  4. A unit that received CDBG assistance for rehabilitation at any point in the past

6. GCHS plans to demolish a lower-income dwelling unit. The recipient makes its required replacement information public on a given date, and demolition itself begins eight months later. Within what overall window must replacement units become available?

  1. A four-year window running entirely forward from the date demolition begins, with no period before the information is made public counted
  2. A window running from one year before the information is made public to three years after the demolition or rehabilitation begins
  3. A two-year window running from the date demolition begins to two years afterward
  4. A ten-year window running from the date the replacement unit is first occupied

7. A replacement unit under section 104(d) is occupied for the first time on a given date. For how long after that date must it be kept as a lower-income unit?

  1. At least 4 years from initial occupancy
  2. At least 5 years, matching the real property use restriction under 570.505
  3. At least 10 years from initial occupancy
  4. There is no minimum period once the unit is initially occupied by a lower-income household

8. Besides the 10-year affordability period, what other conditions must a section 104(d) replacement unit meet?

  1. It must be located within the same census tract as the demolished unit and owned outright by the recipient
  2. It must be a newly constructed unit; acquisition of existing standard housing does not satisfy the requirement
  3. It must rent for no more than the demolished unit's prior rent, regardless of Fair Market Rent
  4. It must be within the recipient's jurisdiction, in standard condition or raised to standard from substandard if vacant at least three months with no one displaced, and sufficient in number and size for the original occupants

9. What must a recipient certify before undertaking an activity that could trigger section 104(d)?

  1. That it has adopted and follows a Residential Antidisplacement and Relocation Assistance Plan covering minimizing displacement, relocation assistance, and replacement units
  2. That it has obtained written approval from the state historic preservation officer for the demolition and for any replacement units
  3. That the demolished units were vacant for at least three months prior to demolition and were never assisted with CDBG funds
  4. That no displaced person qualifies for both URA and section 104(d) benefits on the same project, so no election is ever needed

10. A displaced lower-income person qualifies for both URA assistance and section 104(d) benefits on the same GCHS project. Who decides which set of benefits the person receives?

  1. GCHS, which selects whichever package costs less to administer and explains its choice to the household afterward
  2. The displaced person, who may elect either URA assistance under 49 CFR Part 24 or section 104(d) benefits
  3. TDA, as the state administering agency, based on the project's overall budget
  4. HUD, through a written approval required before either package can be offered

11. Which of the following is included among section 104(d) benefits a displaced lower-income person may elect instead of URA assistance?

  1. A cash payment equal to the Fair Market Rent of the demolished unit multiplied by 10 years
  2. A guaranteed unit in any GCHS-owned property within the recipient's jurisdiction, regardless of size or condition
  3. Advisory services, moving expenses, security deposits, interim living costs, and replacement housing assistance
  4. Reimbursement limited strictly to moving expenses, with all other relocation costs covered only under the URA

12. GCHS demolishes a single occupied lower-income dwelling unit as part of a small rehabilitation project. Does the one-for-one replacement requirement apply only to larger demolition projects, or does it attach at any unit count?

  1. It only applies once five or more lower-income units are demolished in a single project
  2. It does not apply to single-family rehabilitation projects at all, regardless of unit count
  3. It applies only if the demolished unit was already CDBG-assisted prior to demolition
  4. It attaches at any unit count, including a single unit, once an occupied or vacant occupiable lower-income dwelling unit is demolished or converted away from lower-income use

13. Besides someone whose home is physically demolished, which of the following also falls within the URA's definition of a displaced person?

  1. Someone who sells their home voluntarily at market value with no CDBG involvement whatsoever in the sale
  2. A tenant who moves permanently after a notice to move for the assisted activity
  3. Someone who chooses to move for reasons unrelated to the project
  4. Only someone who receives a formal condemnation notice from the recipient

14. Can the URA and section 104(d) both apply to the same GCHS project at the same time?

  1. Yes, both can apply to one project, and a grantee that checks only one has not finished the analysis
  2. No, section 104(d) automatically supersedes the URA whenever both could apply to the same displaced person
  3. No, a project is always classified under only one of the two frameworks
  4. Yes, but only if HUD issues a written determination that both apply
