City of Flagstaff (inside city limits, no HOA on recent listings)

A short-term rental here needs the City of Flagstaff's annual license, an Arizona TPT license, neighbor notification, and the City's insurance, smoke alarm, and fire extinguisher rules. With no HOA showing on recent sales, the City's rules are the main layer, but a subdivision can still carry recorded deed restrictions, so we check the exact rules for the lot before you write.

Getting around

Butler Avenue to I-40, Fourth Street and downtown

Sinagua Heights Drive meets Butler Avenue, which runs west past Fourth Street to the I-40 interchange and on toward downtown and NAU. Foxglenn Park is nearby on Butler, and from several back lot lines the Flagstaff Urban Trail System heads into the forest.


Sinagua Heights is one of the smaller subdivisions on Flagstaff's east side: Sinagua Heights Drive, which turns south off Butler Avenue, and Kokopelli Lane, its one cross street, both ending in cul-de-sacs. There are about 40 addresses, nearly all built in the mid-1990s, with a few homes from the 2000s. Many lots back undeveloped forest and the Flagstaff Urban Trail System, and listings often note forest and mountain views.

We like Sinagua Heights for buyers who want a larger in-town home on a quiet dead-end street with the forest out back.

Homes rarely come up. From October 2023 through October 2026 the MLS shows five sales, all single-family, from $875,000 to $1,300,000 with a median of $1,100,000. Only one closed in the twelve months ending October 2026, at $1,140,000. These are sizable homes: the typical sale was about 3,400 square feet, built in 1995, on 0.29 acre, and median days on market was 50. No homes were listed for sale as of October 2026, so comps here lean on a handful of sales and nearby east-side neighborhoods.

Day to day, it is simple city living: City water and sewer, natural gas, City-plowed streets, and no HOA dues on recent listings. Many homes have lower levels or basements and decks facing the trees, so we look closely at drainage, decks, and roof age. The forest edge means defensible space matters, and we check the flood map and any recorded restrictions for the specific lot. Butler Avenue is the way in and out, and the City's widening project ends right at Sinagua Heights, so plan on construction in the next few years.

Butler-Fourth project ends at Sinagua Heights

The City's Butler-Fourth Improvements Project would widen and rebuild Butler Avenue from the I-40 interchange east to Sinagua Heights, and Fourth Street from Warm Springs Trail to Butler, with separated bike lanes, sidewalks, mid-block crossings, and a new roundabout at Herold Ranch Road. As of September 2026 the design was about 60 percent complete, with construction anticipated to start in 2027.

What makes this neighborhood unique

Sinagua Heights gives you a large mid-1990s home on a dead-end street inside the city, with City water and sewer, no HOA dues on recent listings, and the forest and trail system out the back door on many lots. Because fewer than two homes a year sell, pricing takes care. Before you write, we pull the recorded documents for the lot, look at drainage, decks, and lower levels, check defensible space and the flood map, and walk you through what the Butler Avenue construction could mean for getting in and out.
