Siding in St. Louis

What's different about siding in the City of St. Louis

The first thing to understand is that the City of St. Louis is not part of St. Louis County. The 1876 home-rule split severed the city from the county, and the two jurisdictions have run separate governments ever since. A re-siding project inside the city limits — zip codes 63101 through 63147, roughly — is permitted by the City of St. Louis Building Division through the Office of the Building Commissioner. A re-siding job in Kirkwood, Webster Groves, Maplewood, Clayton, University City, or any other municipality outside the city line is permitted by that municipality or by St. Louis County. Contractors quoting city addresses sometimes default to county paperwork; that is the most common permitting error we see.

The second distinction is the building stock. Central and south St. Louis neighborhoods — Soulard, Lafayette Square, Compton Heights, Shaw, Tower Grove East, Benton Park, Dutchtown, Holly Hills — are defined by load-bearing red brick masonry, where exterior cladding work is concentrated on rear additions, dormers, gables, porches, and detached frame structures rather than the full envelope. The classic St. Louis gable-front brick cottage, often called a flounder or a two-flat depending on plan, typically carries painted-wood or vinyl cladding only on the wood-frame portions. Re-siding one of these is a masonry-coordination conversation as much as a siding conversation. Lafayette Square and Compton Heights also carry a meaningful population of Second Empire homes with decorative wood trim and ornamental fascia that ordinary vinyl crews should not quote.

The third factor is peril. The Lower Missouri and Mississippi confluence sits in a convective-weather corridor that NWS St. Louis tracks year-round. Large hail, damaging winds, and periodic tornadoes drive claim cycles, and the Missouri Department of Commerce and Insurance recognizes impact-resistant exterior products under its property-protection rules at 20 CSR 500-6.100. Many admitted carriers in the metro extend a wind-and-hail premium credit on impact-rated siding that meets ASTM D4226 and recognized hail-resistance ratings. The economic case pencils differently here than in suburban Missouri because many city properties are brick-walled and carry siding only on limited frame elements in the first place.

City of St. Louis permits: Building Division + Preservation Board

Siding work inside the City of St. Louis is permitted through the Building Division under the Office of the Building Commissioner. In a locally designated historic district, the Cultural Resources Office and, for larger or exterior-material changes, the Preservation Board must sign off before the Building Division will issue the permit.

The Building Division handles residential siding permits for the city and enforces the locally adopted International Residential Code with amendments. Like-for-like re-siding on a non-historic property is typically an administrative permit pulled by a city-licensed contractor. Contractors working in the city must carry a City of St. Louis occupancy permit and a Class A or B contractor registration on file; county-only registration does not authorize city work, and addresses on the city side that read as Kirkwood or Webster through a mailing ZIP occasionally confuse even experienced crews.

Historic review runs in parallel. The Cultural Resources Office staffs the Preservation Board, which administers local historic-district standards. Local designation — separate from the National Register — triggers review for exterior changes including siding material, profile alterations, and visible trim changes. Like-for-like wood, fiber-cement, or vinyl replacement on a contributing building is usually approved at staff level in a week or two. Proposed material swaps on a frame addition (vinyl over original wood lap, for example) or on a street-facing elevation route to full Preservation Board, which meets monthly and can add 30 to 60 days to the timeline.

• Building Division online permit system
  Residential siding permits issue through the city's Citizens' Service Bureau and the Building Division's online application portal on stlouis-mo.gov. Payment, inspection scheduling, and final sign-off are tracked in the same system. Contractors must have an active city occupancy permit and current contractor registration before the portal accepts an application under their name.
• Cultural Resources Office and Preservation Board review
  Local historic districts — Lafayette Square, Soulard, Compton Heights, Central West End, Shaw, McKinley Heights, Benton Park, Holly Hills, The Ville, and portions of Tower Grove East among others — require Cultural Resources Office review before a Building Division permit issues. Like-for-like work is reviewed at staff level; material or visible configuration changes go to the Preservation Board.
• Missouri building code — municipal adoption by the city
  Missouri has no statewide residential code, so enforcement is municipal. The City of St. Louis has adopted the IRC with local amendments. A continuous water-resistive barrier behind cladding, proper flashing at openings, and IRC fastening schedules are enforced at inspection. On masonry-wall assemblies the amendments also address J-channel termination and counter-flashing into reglets, which are common inspection sticking points.
• City is not county — confirm jurisdiction before any permit
  ZIP code mailing addresses in the metro routinely span the city and county. A Dogtown address sits inside the city; a Clayton address does not. Contractors who quote a St. Louis County permit for a city parcel — or vice versa — will see the permit rejected and the inspection fail. Confirm parcel jurisdiction on the city or county GIS before the contract is signed.

Typical siding replacement cost in St. Louis

City of St. Louis pricing runs close to the Midwest median on straightforward vinyl work, but the housing stock pushes an unusually large share of city siding jobs into partial-elevation frame work, masonry-coordinated detailing, and restoration-grade wood or fiber cement on contributing buildings. Directional 2026 bands for the city side — not bids.

Ranges synthesized from 2025-2026 St. Louis metro contractor quotes, Missouri DCI impact-resistant product filings, and regional trade reporting. Real quotes vary with wall height, stories, access, sheathing condition, masonry condition, and any Preservation Board outcome.

Neighborhoods where siding looks different

A Lafayette Square restoration is a completely different job from a Holly Hills bungalow or a Dutchtown two-flat. A few neighborhood specifics worth knowing before quoting work:

• Lafayette Square
  The oldest platted park neighborhood west of the Mississippi, rebuilt after the 1896 tornado with a dense collection of Second Empire townhomes. Brick masonry with ornamental wood trim, fascia, and decorative cornices dominates the streetscape. Designated a local historic district — all exterior cladding and trim work routes through the Cultural Resources Office, and material changes go to the Preservation Board. Plan for a specialty restoration carpentry crew and a longer review timeline.
• Soulard and McKinley Heights
  Brick rowhouse and flounder stock south of downtown, much of it 1860s to 1890s. Load-bearing masonry party walls are standard; visible frame elements are limited to rear additions, dormers, and porches. Local historic district. Tuckpointing and masonry repair are almost always coordinated alongside a frame-element re-siding here.
• Compton Heights
  The Julius Pitzman street plan south of Tower Grove Park is one of the metro's most intact collections of late-Victorian mansions, with turrets, decorative gables, and complex trim geometries. Local historic district with strict Preservation Board oversight on material changes. The neighborhood has a long history of restoration-quality wood and millwork.
• Central West End
  Gilded Age mansion territory along Lindell, Kingshighway, and the Portland and Westmoreland private places. Cut stone, brick, stucco, and ornamental wood trim are common. Local historic district. The Preservation Board takes an active interest in any visible cladding or trim changes on contributing and landmark-rated buildings.
• Shaw and Tower Grove East
  Late-Victorian and early-twentieth-century brick housing south of Tower Grove Park, a mix of two-flats, four-families, and single-family gable-front cottages. Portions are locally designated. A significant share of cladding work here is on frame additions and detached garages; vinyl and engineered-wood lap are common on those simpler elements.
• The Hill
  The historically Italian neighborhood south of I-44, famous for its red-brick gable-front cottages on small lots. Not a formal local historic district, so permit review runs through the Building Division on the ordinary administrative track, but visually the neighborhood reads as a preservation zone and owners often voluntarily match traditional materials on porches and frame additions.
• Dutchtown, Holly Hills, and Bevo
  Dense south-city brick neighborhoods of two-flats, gable-front cottages, and bungalows. Dutchtown and Holly Hills both contain locally designated historic areas; large stretches fall outside formal designation. A very common St. Louis re-siding profile — vinyl or engineered-wood lap on frame additions, dormers, and detached structures, with masonry repair as a common add-on.
• The Ville and north-side historic districts
  The Ville is a locally designated historic district with deep African American architectural and cultural significance. Building stock runs from shotgun cottages to larger civic buildings. Preservation Board review applies to contributing structures; staff-level review handles most like-for-like work.

St. Louis metro storm events siding contractors still reference

The city's peril signature is severe thunderstorms, periodic tornadoes, and a newer generation of historic flash-flood events. Claim cycles that shaped current underwriting:

• 2022
  July 25-26 historic flash flooding

  An approximately 1-in-1,000-year rainfall event dumped more than nine inches on parts of the metro in a few hours, overwhelming storm sewers and flooding low-lying neighborhoods from University City through parts of south city. Wall-adjacent damage — water-resistive barrier failures, wind-driven rain intrusion behind cladding, and saturated sheathing on frame elevations — drove a second wave of claims after the initial interior-flood surge.
• 2021
  December 10 tornado outbreak

  The late-season outbreak that produced the Mayfield, Kentucky tornado also spawned confirmed tornadoes across the St. Louis region, with damage scattered through the southern and western suburbs. Mostly a wind event for siding in the city proper — blown-off vinyl panels, cracked boards, and tree impacts — but an outlier date on the metro storm calendar.
• 2023
  June 29 severe weather

  A derecho-style wind event moved across the region with widespread straight-line winds, localized large hail, and significant tree damage in Forest Park, Tower Grove, and the central corridor. Claim volume booked metro crews for weeks and surfaced a large population of brittle older vinyl as total losses.
• 2011
  April 22 Good Friday tornado

  An EF4 tornado tracked through the northwest metro and scored a direct hit on Lambert-St. Louis International Airport's main terminal, with additional damage through Maryland Heights, Bridgeton, and parts of north county. Primarily a suburban event rather than a city event, but the Missouri benchmark for metro tornado risk alongside Joplin and the reference for post-2011 wind-and-hail underwriting.
• 2011
  May 22 Joplin tornado (statewide context)

  Not a St. Louis event — the EF5 was 250 miles southwest — but the Missouri baseline for catastrophic tornado loss and the anchor point for how Missouri insurers approach wind-and-hail underwriting, long-tail supplemental claims, and impact-resistant exterior adoption across the state.
• 2011
  January 31 to February 2 ice storm and blizzard

  A major multi-day winter event that combined heavy ice accretion with follow-on snow. Ice loading on trim, tree impacts, and gutter-and-fascia failures drove a winter claim wave and reinforced the freeze-thaw durability concerns that city inspectors still treat seriously on exterior assemblies.

St. Louis siding FAQ

• Do I need a permit to re-side my City of St. Louis house?
  Yes. The City of St. Louis Building Division requires a building permit for siding replacement. A city-licensed contractor pulls it through the Office of the Building Commissioner. If your property sits in a local historic district, the Cultural Resources Office must sign off — and for material or visible configuration changes, the Preservation Board must approve — before the Building Division will issue the permit.
• My address shows St. Louis on my mail — is that a city or county permit?
  Mailing addresses are misleading here. The City of St. Louis and St. Louis County are separate jurisdictions — the city left the county in 1876. Kirkwood, Webster Groves, Maplewood, Clayton, and University City are all in St. Louis County, not the city. Confirm the parcel on the city GIS (stlouis-mo.gov) or the county GIS before signing any contract; a permit pulled under the wrong jurisdiction will fail inspection.
• I'm in Lafayette Square or Compton Heights. Who reviews my siding and trim work?
  The Cultural Resources Office staffs review for local historic districts, and the Preservation Board rules on material or profile changes to cladding and trim. Like-for-like wood or matching fiber-cement replacement is typically handled at staff level in one to two weeks. A proposed material change — vinyl over original wood lap, for example — routes to full Preservation Board and can add 30 to 60 days. Hire a specialty restoration crew; suburban vinyl installers routinely botch the trim detailing on these.
• Does Missouri offer a discount for impact-resistant siding?
  The Missouri Department of Commerce and Insurance addresses impact-resistant exterior building products under its property-protection rules at 20 CSR 500-6.100, and many admitted carriers writing homeowners policies in the St. Louis metro extend a premium credit on the wind-and-hail portion of the policy when siding carries a recognized impact rating (ASTM D4226 or a manufacturer hail-resistance class). The percentage varies by carrier. Keep the manufacturer certificate and contractor installation documentation on file to claim it at renewal.
• My south-city two-flat is brick — do I even need siding work?
  Often only on the frame portions. Most south-city two-flats are load-bearing masonry, so the cladding conversation is limited to rear additions, dormers, gables, porches, and detached garages. Where those frame elements have failing paint, rotted wood lap, or brittle old vinyl, re-siding them with vinyl, engineered wood, or fiber cement is straightforward. Either way, expect the adjacent masonry parapet or wall cap and the counter-flashing into the brick reglets to be re-detailed at the same time; skipping that step is the single most common water-intrusion source where brick meets cladding on St. Louis homes.
• Should I tuckpoint my brick walls when I re-side the frame portions?
  Almost always, yes. Masonry walls take weather year-round and the mortar joints take freeze-thaw cycles nine months a year. Re-siding the frame elements without addressing failed mortar joints in the adjoining brick is how water keeps getting into the wall cavity even after brand-new cladding goes up. Most reputable city contractors either tuckpoint in-house on these jobs or sub it to a dedicated mason and quote it line-item. A quote that replaces cladding without even inspecting the adjacent masonry is an incomplete quote.
• How long does a City of St. Louis building permit take for a re-siding job?
  For a like-for-like re-siding job on a non-historic property submitted by a city-licensed contractor, the Building Division typically issues administratively within several business days. Inside a locally designated historic district, add Cultural Resources Office review — staff-level approval for like-for-like work generally runs one to three weeks, and a full Preservation Board review adds 30 to 60 days because the board meets monthly.
• When is the best time of year to schedule work in St. Louis?
  Severe-hail and tornado season peaks from late March through early June, with a secondary peak in September and October. Late summer (late July through early September) and mid-to-late autumn are the most reliable scheduling windows for complex work. Winter cold can complicate fiber-cement and vinyl installation, so leave margin on any frame-elevation or trim repair that will not survive another freeze-thaw cycle.
