House at 427 West Twohig
Why it's listed
Built between about 1927 and 1931, this two-story buff brick house at 427 West Twohig in San Angelo reflects the Georgian form of Colonial Revival design. It has a side gable roof and a one-story shed-roofed addition at the rear. The centered entry has a classical broken pediment, fluted pilasters and a single door with a half-round fanlight. Above it, three round-arched windows with ironwork mark the second floor, and the other windows are one-over-one sash with wood screens, paired across the front. The house replaced two earlier houses on the site during a period of city growth and economic expansion. West Twohig was a prestigious street, and owners built as impressive a structure as their budgets allowed. The house is described as in good condition and unaltered from its original appearance. Once a residence, it now serves as offices on a street that has become commercial, and it contributes to its historic neighborhood. Its significance is local and rests on its architecture.
Significance in brief: The nomination argues the house is locally significant for its architecture. It was built during a period of economic growth on West Twohig, a prestigious street, replacing two earlier houses. It remains unaltered from the original and contributes to the historic neighborhood.

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.
