Key Points
- Phoenix City Council voted to allow duplexes, triplexes, and fourplexes inside one mile of the downtown core, complying with state bill HB 2721.
- The law requires every Arizona city over 75,000 residents to adopt similar zoning changes by year-end or lose certain zoning powers.
- Historic districts (Willo, Encanto) mounted strong opposition, fearing loss of neighborhood character and long-term erosion of historic protections.
- Developers are not rushing in—high land prices, teardown costs, permitting hurdles, and economic uncertainty make infill projects slow to materialize.
- Even when built, these units likely won’t be low-income housing; instead, they function as “step-up” housing that frees up other homes in the supply chain.
- Middle housing could increase nearby property values and create more attainable options near downtown—though residents next door may be frustrated.
- HB 2721 protects historic districts with design review, size limits, and authority to delay projects up to one year.
- Mayor Gallego noted the city’s hands are tied, but said lawmakers may try revising the law next session.
Why It Matters to Phoenix-Metro Investors
- More allowed density near downtown supports long-term housing supply, aligning with free-market, pro-development principles.
- Investors holding single-family homes in the core may see appreciation potential as density by-right increases.
- BUT: infill development remains costly and slow—don’t expect rapid waves of plex construction.
- Regulatory friction (design review, historic protections) reinforces the value of professional property management to navigate compliance.
