What the 21st Century ROAD to Housing Act Changes for Buyers and Owners

The 21st Century ROAD to Housing Act became federal law on July 11, 2026, without President Trump's signature. The House cleared the final version 358-32 on June 23, 2026, a day after the Senate approved it 85-5. The bill was presented to the President on June 29, and he said he would not sign it, tying his refusal to the Senate's failure to pass the SAVE America Act. Because he neither signed nor vetoed it within the 10-day window while Congress was in session, it took effect as Public Law 119-101.

The law spans 12 titles and nearly 60 sections. Most of it does not change anything for a buyer on day one. Much of the work falls to HUD, the Federal Housing Finance Agency (FHFA), the Treasury and the states, on deadlines that stretch from a few months to several years. What follows sorts the provisions buyers and owners are most likely to notice, and when each one actually starts.

The short version: what starts when

One caveat applies across the board. Section 1202 states that no additional funds are authorized to carry out the law. The grant programs it creates, including the Innovation Fund and several pilots, depend on Congress providing money through the regular appropriations process.

Building more homes: incentives, zoning and environmental review

Rewards and penalties for local housing growth

The piece with the most bite for local governments is the Build Now Act section. HUD will measure how fast each large Community Development Block Grant (CDBG) recipient, meaning a metropolitan city or urban county, is adding housing units compared with its own past growth, using Census Bureau address data. Recipients at or above the median improvement rate, plus any place growing at 4% a year or faster, share a bonus. Those below the median lose 10% of their CDBG allocation, and that money funds the bonuses. Lower-cost areas, places with above-average rental vacancy, recent federal disaster areas and governments without zoning authority are exempt. The adjustments do not start until the third full federal fiscal year after enactment.

A separate Innovation Fund lets HUD award competitive grants to local governments that have measurably increased their housing supply. The initiatives the law lists as qualifying include allowing duplexes through fourplexes by right, trimming off-street parking requirements and easing lot-size and setback rules.

Zoning guidance, not a federal mandate

The law does not override local zoning. It directs HUD to publish voluntary guidelines and best practices for state and local zoning codes, covering ideas such as reducing parking minimums, allowing accessory dwelling units (ADUs) and permitting small multi-unit buildings by right. HUD must publish a draft for public comment within two years and the final version within three. Cities and states decide whether to use it.

Faster environmental reviews

Several sections narrow how the National Environmental Policy Act applies to housing. Many HUD-assisted housing activities, including new construction and rehabilitation of residential buildings that do not materially alter environmental conditions, become categorical exclusions. Most Rural Housing Service-funded infill projects are exempted. HOME-funded infill construction, property acquisition for affordable housing and certain rehabilitation projects are also exempted from further review. These changes mainly affect subsidized and federally assisted projects rather than privately financed subdivisions, so their effect on the typical resale market will be indirect.

Manufactured and modular homes

The law changes the federal definition of a manufactured home from one built "on a permanent chassis" to one built "with or without a permanent chassis." The steel chassis requirement had made it hard for factory-built homes to look and finance like site-built houses. HUD must write standards and labeling for chassis-free homes, and each state must certify within one year that its laws treat those homes the same as traditional HUD-code homes for financing, title, insurance, taxes and installation. States whose legislatures meet every two years get two years. A state that does not certify must bar the manufacture, installation or sale of new chassis-free homes within its borders.

HUD also becomes the only federal agency whose energy-efficiency standards for manufactured homes can take legal effect. It must adopt minimum standards within a year and update them at least every three years.

The FHA Title I program, which insures loans for manufactured homes and home improvements, gets new maximum loan amounts written into the statute:

• $106,405 for a single-section manufactured home, or $149,782 with a developed lot
• $195,322 for a multi-section home, or $238,699 with a lot
• $43,377 for a lot alone
• $75,000 for improvements to an existing single-family home, including a manufactured home
• An amount HUD sets for building an ADU, which becomes an eligible Title I purpose

HUD must choose a new annual indexing method within a year, and HUD may now set loan terms of up to 30 years. For modular homes, HUD must review FHA construction-loan rules and then begin a rulemaking on an alternative draw schedule.

Mortgage, appraisal and financing changes

Small-dollar mortgages

HUD may launch an FHA pilot program within a year to make loans of $100,000 or less easier to get on owner-occupied one- to four-unit homes. Options in the law include incentive payments to lenders, adjusted FHA costs, and grants to borrowers for down payments, closing costs, appraisals and title insurance. The pilot would end four years after it starts. The law also orders the Consumer Financial Protection Bureau to study how loan officer pay and the caps on points and fees discourage small loans.

Appraisals

The FHA, FHFA, the Department of Veterans Affairs and the Department of Agriculture must each require lenders on federally backed mortgages to have a process for handling a borrower's request for a reconsideration of value or a second appraisal. FHA work also opens to state-licensed as well as state-certified appraisers, and appraisers newly approved for FHA work must complete training on FHA requirements. HUD has 240 days to issue the guidance.

Veterans

Within six months, the FHFA must require Fannie Mae and Freddie Mac to add a line to the Uniform Residential Loan Application telling borrowers who answer "yes" to the military service question that they may qualify for a VA home loan. FHA's existing informed-choice disclosure will also have to show how a VA loan compares.

Investor limits and other provisions

Title X limits purchases of single-family homes by investors that control 350 or more of them, starting January 7, 2027, with a long list of exceptions. That provision has its own rulemaking under way at the Treasury and deserves a separate look. The law also bars the Federal Reserve from issuing a central bank digital currency until December 31, 2030, and includes a set of community bank and deposit-insurance changes that have little direct connection to home buying.

What buyers and owners should watch

• Manufactured-home shoppers: whether their state certifies chassis-free homes on time, and when lenders begin offering financing for them.
• FHA borrowers: HUD mortgagee letters putting the appraisal, Title I and small-dollar changes into practice. Readers weighing an FHA loan can review the basics in this FHA loan guide.
• Homeowners near growing cities: local zoning debates, since block-grant money will eventually ride on housing growth.
• Veterans: the updated loan application form in early 2027.
