The M-Streets, officially Greenland Hills, take their nickname from street names like Mercedes, Merrimac, Monticello, and McCommas. The neighborhood is best known for rows of 1920s and 1930s Tudor cottages with steep gables, arched entries, and brick facades, along with a growing number of carefully expanded homes.
It sits in the northwest corner of East Dallas, close to Lower Greenville, Mockingbird Station, and Central Expressway, which makes it popular with buyers who want older-home character with a shorter drive to Uptown, downtown, and the Park Cities.
Much of the area is covered by conservation district zoning, so additions, second stories, and new construction must meet specific standards. That shapes both what buyers can do after closing and how renovated homes compare with original ones when pricing a sale.

M-Streets questions & answers
Where are the M-Streets, and what are the homes like?
The M-Streets, officially Greenland Hills, are in the northwest part of East Dallas, close to Lower Greenville, Mockingbird Station, and Central Expressway. The nickname comes from street names beginning with M, such as Mercedes, Merrimac, Monticello, and McCommas.
The neighborhood is best known for its 1920s and 1930s Tudor cottages: brick facades, steep front gables, arched doorways, and modest original footprints, many of which have since been expanded. Lots are generally narrow, so homes sit close together and street character is very consistent.
Buyers are often drawn by the location, the walkability to Greenville Avenue restaurants and shops, and the architecture. Because much of the area falls under conservation district zoning, expansion options depend on the specific address. Read the full M-Streets guide.
Is it worth renovating before selling in the M-Streets?
In the M-Streets, targeted updates before selling are often worthwhile, but large renovations usually aren't. Buyers here frequently compare a home against fully renovated competitors, so a home that looks tired can lose value, while a major remodel done quickly to sell rarely returns its full cost.
Projects that tend to make sense: paint, refinished hardwoods, updated lighting, repaired windows, landscaping, and fixing any inspection-level issues. Major projects, such as a kitchen relocation or an addition, require time, permits, and possibly conservation district review, and buyers who want those projects often prefer to do them their way.
Before you start, I'll pull recent M-Streets sales at different renovation levels so we can estimate what each improvement might actually change in price. See also renovating vs. selling as-is.
Much of the M-Streets area is covered by conservation district zoning, which regulates exterior changes, additions, and new construction to protect the neighborhood's Tudor cottage character. The area includes two: the M Streets (Greenland Hills) Conservation District and the M Streets East Conservation District, each with its own ordinance.
For buyers, the practical question is what you'll be able to do later. Second-story additions, rear additions, roof pitch, materials, and the treatment of the front facade can all be regulated. For sellers, it's worth knowing that buyers often price in those limits, and a well-executed, compliant addition can be a selling point.
Check the property on the City of Dallas conservation district map, then read the specific ordinance. I'm happy to help you find it. Related: adding on in a conservation district.
