House at 123 Allen
Why it's listed
This small one-story frame house at 123 Allen in San Angelo was built around 1910-13 on a corner lot in the Fort Concho Addition. Its architect and builder are not known. The house has a pyramidal hipped roof with front and side facing gables, and a small inset porch in the northeast corner supported by columns on brick pedestals. Bay windows accent the plain side facades, the windows are one-over-one double-hung sash, and two entry doors from the porch have transoms above. The style is described as vernacular. The house was listed because it is one of the best and most intact houses in the old Fort Concho Addition, a middle-class neighborhood that developed after 1905. The area once held many similar houses, but nearly all have been altered. A mixed commercial and industrial section of the city adjoins the neighborhood. The property is on its original site, is in good physical condition, and covers less than one acre.
Significance in brief: The house is described as one of the best and most intact houses in the old Fort Concho Addition, which developed after 1905. This middle-class neighborhood once had many similar houses, and almost all have since been altered. Significance is claimed locally under architecture.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
