According to Stanley Kurtz, writing at National Review:
With the introduction of his massive, $2.3 trillion "infrastructure" bill, President Joe Biden
...... 46th president of the U.S. Sleazy Dem mschine politician, paterfamilias of the Biden Crime Family......'s campaign to end suburban single-family zoning has begun. If you think this issue was debated and resolved during the 2020 presidential campaign, you are mistaken. It's true that Biden's campaign platform openly and unmistakably pledged to abolish single-family zoning. As soon as President Trump made an issue of that pledge, however, Biden went virtually silent on the issue and the Democrat-supporting press falsely denied that Biden had any designs on single-family zoning at all. Now that he's president, Biden's infrastructure bill openly includes programs designed to "eliminate" single-family zoning (which Biden calls "exclusionary zoning").
Kurtz's account is a total green-eyeshade number made easily readable, explaining that Biden's plan is to abolish single-family zoning by holding out the carrot of federal funding to suburban towns.
The wildly overreaching Obama-Biden era Affirmatively Furthering Fair Housing (AFFH) regulation — which Biden has pledged to revive — works in a similar fashion. The difference is that by adding another gigantic pot of federal money to the Community Development Block Grants that are the lure of AFFH, Biden makes it that much harder for suburbs to resist applying — and that much more punishing to jurisdictions that forgo a share of the federal taxes they've already paid so as to protect their right to self-rule.
In other words, take the king's penny, do the king's bidding. The Biden plan would nationalize zoning in the hands of the feds (just as the feds would take over elections with the congressional Democrats' despicable H.R. 1), meaning that anyone who would like the peace of living in the suburbs, and might enjoy seeing his kids go out and ride bikes without supervision, is s[ooo] out of luck. The feds would take over in what they claim is the name of racial "balancing."
