The McCandless Building is a historic building located in Mount Pleasant, Iowa, United States. This three story brick Italianate structure was built in 1862 by local builder William McCandless. With the arrival of the railroad in 1856, Mount Pleasant was in need of new commercial buildings to house businesses and services that were opening in the expanding town. They were built on the north and east side of the town square. The Italianate was a prominent style used in the city at this time having been used by about a dozen buildings. This buildings features three round arch windows on the second and third floors with brick patterned hood molds. The storefront has been altered slightly, and the heavy wooden cornice that graced the top of the main facade was removed some time ago. The building was listed on the National Register of Historic Places in 1991.

The Masonic Temple Theater (subsequently the Temple Twin Theaters, and in 2013 the Main Street Cinemas) is a historic building located in Mount Pleasant, Iowa, United States. Built in 1923, it combined both commercial and fraternal functions in one building. The theater company paid for the construction of the lower level, and the Masons paid for the upper level. The Masons continued to occupy the space until 1989 when they moved to another facility. The building was designed in the Neoclassical style by Owen, Payson & Carswell, and K.A. Bergdahl was the contractor who built it. Neoclassical features include the balustrade, the medallion with the Masonic insignia, volutes above the windows, the parapet roof, and the ornamental frieze and cornice. The building was listed on the National Register of Historic Places in 1991.

National State Bank is a historic building located in Mount Pleasant, Iowa, United States. Because this two story, brick Italianate structure was built specifically as a bank, it features a chamfered corner, which was commonly used to designate a bank in the last quarter of the 19th century. However, it combines other features typical of an Italianate commercial building in an unusual way. The secondary facade has segmental arched windows that are regularly spaced, while the primary facade has the windows in a sophisticated arrangement that one would expect of an architect-designed building. (The potential architect of this building, or even its builder, are unknown.) The metal cornice has widely spaced brackets on the primary facade and more typically spaced on the secondary facade. It also lacks an identification pediment on the corner, which is typical of the style. The building was listed on the National Register of Historic Places in 1991.

First National Bank is a historic building located in Mount Pleasant, Iowa, United States. The bank was first located on this corner in the 1860s. Its first building was a small, brick Italianate structure. This building replaced it in 1923. It is a two-story stone structure designed by Chicago architect Paul V. Hyland in the Neoclassical style. It is unique in Mount Pleasant in that it is the only stone building facing the square, and it reflects more of a public building instead of a commercial building. It is similar in style to the Henry County Courthouse, which is diagonally across the square. The exterior of the primary and secondary facades is composed of ashlar limestone and features paired pilasters on the corners of the primary facade, and a single column in the Corinthian order that flank the main entrance. It is capped with a simple classical cornice and parapet roof. The alley side of the building is composed of red brick. The building was listed on the National Register of Historic Places in 1991.

The Budde–Singer Building is a historic building located in Mount Pleasant, Iowa, United States. This three story, brick Italianate structure was built in 1882. It replaced a similar building that had been built in 1856 and destroyed in a fire. Its early Italianate style is unusual for this time period, but it fits into its streetscape with similarly designed buildings, including the neighboring Brazelton House Hotel. The Budde–Singer Building features round arched windows with brick patterned hoodmolds on the second and third floors, and a bracketed wooden cornice. The first floor storefront has been somewhat altered, and the exterior of the building has been painted since about 1909. It was listed on the National Register of Historic Places in 1991.

The Former Mount Pleasant Public Library is a historic building located in Mount Pleasant, Iowa, United States. The library here was established in 1875. The community applied to Andrew Carnegie for a grant to build a new building, which was accepted on January 13, 1903. They were initially granted $10,000 and then were given a further $2,500. The Chicago architectural firm Patton & Miller designed the Romanesque Revival structure. They adapted Henry Hobson Richardson's Thomas Crane Public Library (1882) for this building. Unlike the Crane Library, this building is primarily brick with rough stone used for a short tower on the main facade and for the trim. It also features an asymmetrical grouping of intersecting gables. The building opened on Wednesday, February 22, 1905. An addition was built onto the rear of the building in 1926. It was designed by the Des Moines architectural firm of Dougher, Rich & Woodburn. The building was listed on the National Register of Historic Places in 1983. The library has subsequently moved to another facility and this building now houses a branch of Southeastern Community College.

The Brazelton House Hotel is a historic building located in Mount Pleasant, Iowa, United States. William P. Brazelton was an early leader in the city's development. He owned the Brazelton Banking House and he was one of the directors of the Brazelton House Company, which built the hotel. It is not clear, specifically, why the hotel bears his family name. The construction of the hotel in 1856 coincided with a building boom in Mount Pleasant with the extension of the Burlington and Missouri River Railroad into town. It was built with the belief that Mount Pleasant would need a large first class hotel, but it had financial problems from the beginning and went through a series of owners until it no longer functioned as a hotel about 1970. The building was listed on the National Register of Historic Places in 1986. In 2015 the upper floors were converted into apartments while the main floor continued to house retail businesses. At four floors it is the tallest building in the central business district. It was originally an "L" shaped building, but a 1911 renovation covered the courtyard and created a two-story lobby. The building exhibits elements of the Italianate style, notably found in the bracketed eaves.

Henry County Savings Bank is a historic building located in Mount Pleasant, Iowa, United States. Because this two story, brick Italianate structure was built specifically as a bank, it features a chamfered corner, which was commonly used to designate a bank in the last quarter of the 19th century. Other features typical of an Italianate commercial building include segmental arched windows, a corbeled brick frieze, and a bracketed metal cornice. The building was listed on the National Register of Historic Places in 1991.

The Masters Building is a historic building located in Mount Pleasant, Iowa, United States. Completed in 1937, this two story, brick structure is an adaptation of the commercial Art Deco and Art Moderne styles. The decorative elements are found in the brick patterning and cast concrete panels on the facade. There are three other buildings on this same block that were built about the same time and use the same decorative techniques, with the Masters Building being the best example. This area was an expansion of the central business district after the construction of city hall across the street in 1936. A plumbing business, for which this building was constructed, was located on the first floor. There are three apartments on the second floor. The building was listed on the National Register of Historic Places in 1991.

Mount Pleasant City Hall is the official seat of government of the city of Mount Pleasant, Iowa, United States. This 1½-story stone structure was designed by Burlington, Iowa architect William Weibley, and constructed by local builder K.A. Bergdahl. It is an eclectic combination of Colonial Revival styles. For the most part it reflects Georgian Revival aesthetics with its symmetrical facade and the pilasters that flank the main entrance. The stepped ends of the gable roof and the projecting gable above the main entrance reflect the Dutch Revival influence. The random ashlar stone used in its construction was salvaged from the Seeley Memorial YMCA-high school that was destroyed in a 1932 fire. The city hall's construction in 1936 was a Works Progress Administration project. The east wing, which has been altered from its original appearance, originally housed the city's police and fire departments before they moved to their own buildings. City hall was listed on the National Register of Historic Places in 1991.

The Union Block of Mount Pleasant, Iowa, was built by William McCandless in 1861. Historically it was used as offices and by the county courts. In the Union Block in 1869, Arabella A. Mansfield became the first woman in the United States awarded a license to practice law. The third floor housed the Opera House or Union Hall, a gathering place for the community. Early supporters of women's rights and civil rights spoke there, including Frederick Douglass, Bronson Alcott, Anna Dickinson, and possibly Elizabeth Cady Stanton.Preservation Iowa had listed Union Block on its most endangered buildings list because of its poor condition and lack of preservation plan. The building was badly damaged by an early morning fire on Jan. 25, 2011.

The Timmerman–Burd Building is a historic building located in Mount Pleasant, Iowa, United States. The previous building on this lot was destroyed in a fire in 1883 and Henry Timmerman had this building constructed to replace it the same year. The two story brick structure is one of several building facing the town square in the Italianate style. This building features a single storefront, and four segmental arch windows on the second floor with simple brick patterned hood molds. The bracketed metal cornice at the top of the main facade was mass-produced and likely ordered from a catalog. Burd worked for Timmerman and took over the business. This building housed a shoe store as late as the 1990s. It was listed on the National Register of Historic Places in 1991.
