The Revitalizing America's Housing Act tackles housing affordability through multiple approaches. First, it pushes local governments to adopt policies that make housing easier and cheaper to build—things like allowing duplexes and apartment buildings in single-family neighborhoods, reducing parking requirements, streamlining building permits, and allowing smaller lot sizes. Communities that receive federal housing grants must report on whether they've adopted these policies or explain why not, though they're not required to actually implement them.

The bill also helps specific groups buy homes more affordably. Police officers, firefighters, and emergency medical technicians living in public housing pay reduced rent (5-15% of their income instead of the standard amount). These first responders, including volunteers, can also buy discounted homes through federal programs regardless of neighborhood. Veterans' disability payments won't count against them when applying for housing assistance, and the bill creates a new tax credit for developers who build affordable homes in low-income neighborhoods, offering credits up to 35% of development costs.

On the tax side, the bill doubles the capital gains exclusion when you sell your home—from $250,000 to $500,000 for single filers and $500,000 to $1,000,000 for married couples filing jointly, with these amounts increasing annually for inflation. It also expands tax incentives for investing in opportunity zones to include regular business income, not just investment gains. The bill directs the government to study why middle-class families are being priced out of housing and to recommend ways federal programs can better serve them. Additionally, it protects energy efficiency standards for transformers and includes various technical changes to homeless assistance programs.
