HUD Section 221(d)(4)

HUD 221(d)(4) Construction Requirements: Bonds, Builders Risk, Insurance and Retainage

For Section 221(d)(4) new construction and substantial rehabilitation, the MAP Guide revision dated March 19, 2021, calls for corporate surety payment and performance bonds of 100% of HUD's estimated construction cost each, or a cash deposit or letter of credit of 15% or 25% depending on the building type. During construction it also sets a $1 million per occurrence and $2 million aggregate liability minimum with owners and contractors protective coverage, a completed value builders risk form naming the borrower with a mortgagee clause, Davis-Bacon wages, a 10% retainage and an independent CPA cost certification. Terms can change through later Mortgagee Letters or a newer guide, so confirm the current requirement with the lender and HUD before pricing the job.

Key Decision Points

  1. Section 221(d)(4) insures mortgages for the new construction or substantial rehabilitation of rental housing, and Davis-Bacon wage rules apply to both Insurance of Advances and Insurance Upon Completion.
  2. For costs over $500,000, the MAP Guide calls for 100% payment and performance bonds or a cash deposit or letter of credit of 15% (buildings of 4 stories or less) or 25% (elevator buildings of 5 or more stories).
  3. Sureties must be on the Treasury's Circular 570 list, and the performance bond names the lender and HUD as obligees.
  4. Construction-period liability starts at $1 million per occurrence and $2 million aggregate, endorsed for owners and contractors protective coverage.
  5. Builders risk is a completed value form at 100% of insurable value, with the mortgagor as insured and a non-contribution mortgagee clause.
  6. This page reflects the MAP Guide revision dated March 19, 2021; confirm the current guide and any later Mortgagee Letters.

What Section 221(d)(4) Insures and Which Guide This Page Reflects

The MAP Guide (HUD Handbook 4430.G) states that Section 221(d)(4) insures mortgages for the new construction or substantial rehabilitation of rental housing. The lender is approved by HUD under its Multifamily Accelerated Processing program, but the construction requirements that reach the developer and its general contractor come from HUD's guide and closing forms, not from a negotiated loan exhibit. That is the main difference from a private construction loan: many of the bond, insurance and retainage terms are program rules rather than credit terms.

This page reflects the MAP Guide revision dated March 19, 2021. HUD issues Mortgagee Letters that can change figures in the guide, and a newer edition may exist. Confirm the current guide and any later Mortgagee Letters with the lender before relying on a number here.

Loan sizing shapes how much equity the developer brings, which in turn shapes the surety's view of the job. Under the guide's loan-to-replacement-cost test (Criterion 3), the ratio is 90% for projects with 90% or more rental assistance, 87% for Affordable Housing and 85% for market rate. Commercial space can be up to 25% of net rentable area and 15% of effective gross income, and the guide expects absorption not to exceed 18 months from delivery of the first units. These are program facts; whether a loan is approved, and at what amount, is decided by the lender and HUD.

Payment and Performance Bonds or Cash and Letter of Credit by Building Type

Section 3.2.7.A requires assurance of completion of construction in the form of a combined performance and payment bond or cash or a letter of credit in an amount approved by HUD. Section 8.14.C.13 then sets the amounts by building type for construction or rehabilitation costs over $500,000.

  • Non-elevator buildings, or elevator buildings of 4 stories or less: corporate surety payment and performance bonds, each for 100% of HUD's estimated cost of construction or rehabilitation, or a cash deposit or letter of credit of 15% of that estimate.
  • Elevator buildings of 5 or more stories: the same 100%/100% bonds, or a cash deposit or letter of credit of 25% of HUD's estimated cost.
  • The cash or letter of credit route uses a Completion Assurance Agreement (form HUD-92450, and HUD-92450M at closing), which the general contractor funds with a cash deposit or an unconditional, irrevocable letter of credit.

HUD Bond Forms, Obligees and Circular 570 Sureties

HUD prescribes the bond forms. The Closing Guide (Sections 19.5.6.1 to 19.5.6.3) names the Performance Bond-Dual Obligee, form HUD-92452M, which must name the lender and HUD as obligees, and the Payment Bond, form HUD-92452A-M, which must name the lender, HUD and the borrower. The lender and HUD keep first priority right to call the performance bond, and no equity investor may be named as an obligee, which matters on a tax credit deal where the investor may expect bond rights.

Sureties must be on the U.S. Treasury's accredited list in Circular 570, and the bonds must not exceed the limits listed there for that surety. The surety must send power of attorney confirmation on the day of closing. A letter of credit may replace cash for completion assurance at the lender's option, and the guide says HUD will neither review the letter of credit nor render an opinion on its sufficiency.

A surety bond is credit, not insurance. If HUD or the lender calls the bond, the surety performs or pays and then typically looks to the contractor and its indemnitors for recovery, subject to the terms of the bonds issued.

Liability, Auto and Additional Insured Terms During Construction

Section 3.9.1 sets the construction-period casualty and liability minimums. Section 3.9.3.A then requires HUD and the lender to be named as additional insured, with the clause loss payable to the mortgagee, its successors and assigns. It also requires carriers to hold an A.M. Best Financial Strength Rating of B+ or better. A contractor whose program is written with a lower-rated carrier may need to change markets before closing.

  • General liability: a Commercial General Liability form with limits of not less than $1 million per occurrence and $2 million in the aggregate, endorsed to include owners and contractors protective coverage.
  • Auto: the greater of the state minimum or $300,000 for one person and $500,000 for more than one person, plus $100,000 property damage, applying to owned, non-owned and hired vehicles.
  • Flood: in a Special Flood Hazard Area, flood insurance is required during construction when the property becomes insurable (see the flood section below).

Builders Risk on the Completed Value Form with a Mortgagee Clause

HUD's Property Insurance Requirements form (the edition shown is dated 07/2005) asks for a standard Builders Risk Completed Value form for fire, extended coverage and vandalism and malicious mischief, written for 100% of the insurable value of the completed building or buildings and in force by the first insured advance. The policy shows the mortgagor as the insured; the general contractor and subcontractors may be additional insureds as their interests may appear, and the policy carries a non-contribution mortgage or mortgagee clause payable to the mortgagee and the FHA Commissioner.

The MAP Guide's cost estimating guidance adds that builders risk may be placed by either the general contractor or the borrower and that the contractor commonly places it, but the borrower must be named as an insured party under the form's requirements. Where the contractor buys the policy, the declarations, insured wording and mortgagee clause are worth checking against the form line by line before the first draw. Perils beyond those the form names, along with sublimits and deductibles, can vary by carrier guidelines and programs.

Flood Amounts: Two HUD Passages That Differ

The two HUD documents state the flood amount differently, and this page does not reconcile them. The MAP Guide (March 2021, Section 3.9.1) requires flood insurance during construction in a Special Flood Hazard Area once the property becomes insurable, in an amount of at least the greater of the NFIP maximum or the replacement cost of the bottom two stories above grade.

HUD's Property Insurance Requirements form (07/2005, item 6) states the amount as at least the lesser of the outstanding principal balance or the NFIP maximum. The MAP Guide is the newer document, but which passage controls on a given loan is a question for the lender and HUD. Ask the lender to state the flood amount it will accept in writing before binding.

Davis-Bacon, Copeland Act Payrolls and Retainage Steps

Section 3.2.2 states that Davis-Bacon wage requirements apply to new construction and substantial rehabilitation for both Insurance of Advances and Insurance Upon Completion. Under Section 3.2.6.A, the general contractor and all subcontractors must comply with federal wage and reporting requirements under the Davis-Bacon Act and the Copeland Act, which requires weekly certified payroll reports. The guide excludes off-site improvements, and demolition or site work done before the federal nexus (a pre-application or firm commitment application to HUD).

Section 12.15.5 provides for a 10% holdback from the contractor's monthly payments. After 50% completion, retainage may drop from 10% to 5% until 75% completion and then to 2.5% until Final Endorsement, if the contractor has no identity of interest above a 5% equity interest, the surety consents in writing in advance and HUD approves. A contractor with an identity of interest above 5% generally cannot have retainage released until Final Endorsement, with limited exceptions. Retainage held to the end is working capital the contractor's surety typically weighs when it sets the bond line.

Cost Certification and Latent Defect Assurance at the End of the Job

Section 3.2.5 requires the borrower to submit a cost certification prepared by an independent Certified Public Accountant, and the final mortgage can be reduced after HUD reviews it. General contractors and subcontractors must submit their own cost certification if a cost-plus construction contract is used or there is an identity of interest with the borrower.

Latent defect assurance is stated in two passages with different bases. Section 12.16.S, for Insurance Upon Completion, requires a builder's warranty and a latent defect agreement plus either a cash escrow deposit of 2.5% of the total cost of construction held for 15 months or an irrevocable letter of credit for 2.5% of the cost of construction. The Closing Guide's list for Insurance Upon Completion closings (Section 19.6.5.4.B, item 6, Escrow Agreement for Latent Defects, form HUD-92414M) describes a cash escrow of 2.5% of the principal amount of the Security Instrument held 15 months, a letter of credit or a surety bond on form HUD-3259 from a Circular 570 surety for 10% of the construction contract, effective for two years after Project Substantial Completion. Ask the lender which base it will apply.

Before You Ask for a Quote

What to Gather

  • The lender's statement of which MAP Guide edition and Mortgagee Letters it applies
  • HUD's estimated cost of construction and the building type and story count
  • Your surety's Circular 570 listing and the bond amount it can write
  • Current liability, auto and builders risk declarations with carrier ratings
  • Flood zone determination for the site
  • Any identity of interest between the contractor and the borrower

What to Ask the Insurer or Surety

  • Will the contractor post 100% bonds or a cash deposit or letter of credit?
  • Which flood amount will the lender accept in writing?
  • Who places builders risk, and does it name the borrower with the mortgagee clause?
  • Does the retainage reduction schedule apply to this contractor?
  • Which latent defect assurance and base will the lender require?
  • Are any off-site or pre-nexus site work items outside Davis-Bacon?
Quick Answer

Under the March 19, 2021, MAP Guide, a 221(d)(4) general contractor typically posts 100% payment and performance bonds from a Circular 570 surety, or cash or a letter of credit of 15% or 25%, and carries $1 million/$2 million liability with owners and contractors protective, a completed value builders risk and Davis-Bacon payrolls.

Common Mistake

Assuming a private-lender insurance exhibit carries over. HUD sets the bond forms, obligees, carrier rating and builders risk wording, and a contractor's existing program may not match them at closing.

Broker Perspective

We map the contractor's bonds and policies against the MAP Guide and the HUD forms the lender names, then flag gaps such as carrier rating, insured wording or flood amount before the closing package is assembled.

Coverage Impact

Builders risk and liability respond only as written; the forms, endorsements and limits issued decide what applies, subject to underwriting and the terms of the bonds and policies issued.

Questions Buyers Ask

Does a 221(d)(4) loan require payment and performance bonds?

Under Section 8.14.C.13 of the March 2021 MAP Guide, for costs over $500,000 the contractor provides 100% payment and performance bonds or a cash deposit or letter of credit instead: 15% of HUD's estimated cost for buildings of 4 stories or less and 25% for elevator buildings of 5 or more stories. Confirm the current guide with the lender.

Which sureties can write HUD 221(d)(4) bonds?

The Closing Guide requires a surety on the U.S. Treasury's Circular 570 list, and the bond must not exceed the limit listed there for that surety. The surety sends power of attorney confirmation on the day of closing.

Who is the named insured on 221(d)(4) builders risk?

HUD's Property Insurance Requirements form shows the mortgagor as the insured, with the contractor and subcontractors as additional insureds as their interests may appear, and a non-contribution mortgagee clause payable to the mortgagee and the FHA Commissioner. The contractor commonly places the policy.

What liability limits does HUD require during construction?

Section 3.9.1 calls for a Commercial General Liability form of at least $1 million per occurrence and $2 million aggregate, endorsed for owners and contractors protective coverage, plus auto at the greater of the state minimum or $300,000/$500,000 with $100,000 property damage. HUD and the lender are named as additional insured.

Can retainage be reduced on a 221(d)(4) job?

Section 12.15.5 starts at a 10% holdback and allows steps to 5% after 50% completion and 2.5% after 75%, if the contractor has no identity of interest above 5%, the surety consents in writing and HUD approves.
