Kenwood's Renovation Challenges: What's Behind These Walls
1. Cast Iron Plumbing — Universal in Every Pre-1975 Kenwood Home
Every 1912–1945 home in Kenwood has cast iron drain, waste, and vent piping. Cast iron has a functional lifespan of 50–70 years. The oldest Kenwood homes are now over 110 years old. The pipes are not aging — they're past the end of their designed service life.
Here's the silver lining specific to Kenwood: most bungalows have pier-and-beam foundations — the house is raised off grade, with accessible space underneath. A plumber can reach the drain lines from below without cutting concrete. That makes cast iron replacement significantly less invasive and less expensive than in slab-on-grade construction. Replacement typically runs $10,000–$30,000 depending on home size and access conditions.
2. The Galley Kitchen Wall — Load-Bearing by Design
The wall between your Craftsman bungalow's kitchen and dining room is almost certainly load-bearing. The right approach: pull structural drawings, engineer a proper replacement beam (typically a laminated veneer lumber beam or steel), install the beam with proper point loads to the foundation, and then do the finish work around it.
In a 1920s bungalow, the original framing was true-dimension lumber: a 2x4 was actually 2 inches by 4 inches, not the 1.5x3.5 of modern lumber. That affects how modern cabinets, trim, and millwork align with the original structure. Our carpenters measure everything in-field; they don't assume standard dimensions in a hundred-year-old home.
Per Jeremy Wharton on the typology we see across Kenwood and the rest of pre-1945 St. Pete: “A lot of the times in St. Petersburg, where we do most of our work, we see small cramped kitchens, old galley kitchens that sit on the back of the house. A lot of times, we saw one today that had the kitchen stuffed onto what used to be, I think, a sleeping porch, so it was part of an addition with a sloped floor, and the kitchen itself was an afterthought.” That sleeping-porch pattern shows up in Kenwood specifically when an early addition pushed the kitchen out the back of a Craftsman bungalow before air conditioning made screened porches obsolete.
3. Historic District Navigation — Four LHDs, One Process
Kenwood was listed on the National Register of Historic Places in 2003. The National Register designation is honorary — it carries no exterior modification requirements for most residential properties. The four local historic districts within Kenwood are different. These areas, including the Southwest Central Kenwood LHD designated in April 2021, require a Certificate of Appropriateness (COA) from the City's Historic Preservation Board before any exterior building permit can be issued.
The honest timeline, from Jeremy Wharton: “That department is really bad at any level of timeliness or accountability, so it very easily adds two to four months.” The board does not rubber-stamp; submissions that come back with requests for more information add weeks. We have run COA-required work in Historic Kenwood and St. Petersburg's other historic districts for years without an outright rejection on a Kenwood scope. We know what the board expects and how to prepare a submission that does not come back with second-round requests.
On the build side, per Jeremy Wharton: “The historic preservation board is just an added level of oversight in the application and permitting process. They do come out at some point when we call them out during the project to check and make sure that we have complied with all of the things that we said we would do in terms of the historical work.” That mid-project on-site verification cadence is the difference between a clean COA close-out and a punch list of board callbacks at the end of construction.
4. Knob-and-Tube Wiring and Lath-and-Plaster
Every Kenwood home built before the late 1930s was wired with knob-and-tube — separate hot and neutral conductors suspended on ceramic knobs, no grounding, 60-amp service panels. Modern kitchens and bathrooms require significantly more power. Many insurers won't write policies for homes with active knob-and-tube wiring, which forces the issue when new buyers finance a purchase.
Those walls are lath-and-plaster: narrow wood strips nailed to studs, covered in three coats of plaster. Original plaster walls are actually excellent — more durable than modern drywall, with better acoustic and thermal properties. They're also harder to repair invisibly. Our tradespeople can patch plaster to match original finishes without making every rewired room look like a drywall patch job.
