Iowa City commission approves reconstruction of front deck at 420–422 Northland Street

The Iowa City Historic Preservation Commission approved a certificate of appropriateness for reconstruction of a front deck at 420–422 Northland Street, approving an exception to the commission’s guidelines for an uncommon situation.

The decision came after staff said the house — located in the Northside Historic District and believed to appear on an 1868 bird’s-eye view of Iowa City — has been significantly altered over time. Staff recommended approval because applicants plan to reuse a substantial portion of the existing deck materials while replacing deteriorated structure members. Jessica (staff member) told the commission the structure first appears on Sanborn Fire Insurance maps in 1899 as a brick duplex and later showed wood siding and porch changes across the 20th century. She said asbestos siding was added in 1977, porch columns were replaced with wrought iron in the 1950s–60s, and porch roof and columns were removed in 1998.

Applicant Daniel Lepetka, who said he has lived in the house since about 2010, told the commission the deck has been in place for decades and the work will include tuckpointing the front foundation, replacing several boards, bolting the ledger board to the masonry wall, reusing existing flooring where possible and repainting the railings. He said the owner previously spent about $9,000–$10,000 on an interior central staircase.

Commissioners discussed how the city’s guidelines apply. Staff said handrail and balustrade guidelines normally apply to new decks; the unusual facts here — that a permit is required because of the extent of reconstruction but that many original materials will be reused — justified an exception for an “uncommon situation.” One commissioner said they would prefer removing the siding in the future to reveal brick but agreed the exception is appropriate because the property is already heavily altered.

Commissioner Celergan moved to approve the certificate of appropriateness as presented in the staff report with an exception for an uncommon situation; the motion was seconded and passed by voice vote. The commission’s approval authorizes the applicant to proceed with reconstruction under the terms described in staff’s presentation; the final building permit will reflect the specific attachment method and structural repairs.

The commission’s record includes staff photos from January and August showing existing posts, reused flooring and rubble beneath the deck. Staff noted that constructing a deck between a street and a street‑facing facade is disallowed when it detracts from the neighborhood, but judged reuse and continued attachment to the house here compatible given the house’s alterations and existing condition.
