How do we repair cracked stucco on our HOA's condo or townhome buildings?

By OurHOA · General information · Revised September 27, 2026

How an HOA board repairs cracked stucco: find the water first, sound the walls, choose patch or re-clad, check weep screeds and lead paint, then bid by unit price.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

Treat the cracks as a symptom and go looking for the water. Have a building envelope consultant or engineer tap every elevation for hollow spots, take moisture readings and open a few inspection holes. Fix the leaks they find first: gutters, flashing, sprinkler overspray, stucco buried in soil. Then patch what is sound, re-clad what is not, and paint the whole elevation if the patches will show. Bid the repair with unit prices, because nobody knows how much stucco is loose until the crew starts removing it. Some cracking is normal. The Department of Energy's Building America Solution Center says stucco will always crack, even when installed perfectly, and relies on the drainage layer behind it. Your job is to sort cosmetic cracks from the ones letting water into the framing. Rules vary by state, by city and by your governing documents, and this guide is general education, not legal advice.

Whose wall is it

Settle who pays before you hire anyone. In a condominium the exterior walls are usually common elements. Texas Property Code 82.107(a) makes the association responsible for maintaining, repairing and replacing the common elements, except as the declaration provides. Florida Statutes 718.113(1) says the same for Florida condos, with an exception for limited common elements the declaration assigns to owners. Colorado's 38-33.3-307(1) follows the same pattern and also requires each owner to give the association access through the unit when a repair reasonably needs it. Townhome declarations vary more. Some put every exterior surface on the association, some put walls on owners, and some split it so the association paints and the owner repairs. Read the maintenance section and any maintenance chart before you send one notice, and if the wording is unclear, get the attorney's reading in writing.

Read the cracks, then find the water

The National Park Service brief on stucco repair was written for historic buildings, but its diagnosis fits any stucco wall. Most deterioration, it says, comes from water getting in through the roof, around openings, or up from the foundation, with leaking gutters and downspouts among the usual causes. Fix those before touching the stucco. Water rots or rusts the lath, and the stucco eventually loses its bond and pulls away. Fine hairline cracks spread across a wall are usually shrinkage. Diagonal cracks from window corners, rust stains below a crack, bulges and hollow-sounding areas point to a wall that needs opening. The NPS brief describes the test: loose areas that have lost their key echo with a hollow sound when tapped gently with a wooden or acrylic mallet. Check the base of every wall too. Soil, mulch or a patio slab against the stucco buries the weep screed, and water inside the wall has nowhere to go. Ask the consultant for a marked-up elevation of each building showing hollow areas, moisture readings and inspection openings, with a recommendation for each area: seal, patch, or remove and re-clad. Include the interior stains and soft drywall owners have reported. If the building is less than about ten years old, call the association's attorney before any demolition. Failing stucco on a young building may support a construction defect claim, and tearing the evidence off the wall can weaken it.

Patch, recoat or re-clad

The NPS brief says small hairline cracks can be sealed with a thin slurry of the finish coat ingredients, or even a coat of paint. It also says commercial caulk is the wrong material for them, because it weathers differently, collects dirt and leaves a visible stripe. Keep caulk for the joints where it belongs, around windows, doors and penetrations. Our guide on replacing failed sealant and caulking on HOA buildings covers those joints. Larger cracks and hollow areas get cut out down to the lath or masonry, squared off, and rebuilt in coats matching the original thickness. On a scored wall, square the patch to the score lines. On smooth stucco, scattered patches rarely disappear, so budget to paint or recoat the whole elevation. Match the patch mix to the old stucco's strength and makeup. A much harder mix moves differently from the wall around it and can crack at the edges. Re-clad a wall when the report finds wet or rotted sheathing, rusted lath, a failed or missing water-resistive barrier, or hollow areas across most of an elevation. Patching over any of those hides the problem until the next inspection.

What the code expects on a re-clad wall

A wall stripped to the framing has to go back to the code your city adopted, so ask the building department about permits and whether an inspector wants to see the barrier and lath before the first coat. For reference, the 2021 International Residential Code, which covers most townhomes, and the 2021 International Building Code, which covers most condo buildings, use the same weep screed rule in sections R703.7.2.1 and 2512.1.2. The screed sits at or below the foundation plate line, at least 4 inches above the earth or 2 inches above paved areas, and it has to let trapped water drain out. The water-resistive barrier laps its flange. Over wood-based sheathing, IRC R703.7.3 calls for two independent barrier layers or an equivalent, plus a drainage gap in moist and marine climate zones, and IBC 2510.6 has a similar rule. The IRC also makes the finish coat of three-coat work wait at least seven days after the second coat, unless the work follows ASTM C926, so plan on a week or more per wall. Your city may be on a different edition, so confirm the numbers with the building official. Many Florida condos are concrete block with stucco bonded straight to the masonry and no drainage layer at all, so the engineer should say which kind of wall each building has.

Lead paint and silica dust

Painted stucco on a building built before 1978 falls under EPA's Renovation, Repair and Painting rule. EPA's 2026 small entity compliance guide exempts minor exterior work that disturbs 20 square feet or less of painted surface, and the exemption does not apply to demolition or window replacement. Anything larger needs an EPA-certified firm and lead-safe practices. The rule covers painted surfaces only, so ask the consultant which walls were ever painted. Chipping stucco also puts crystalline silica in the air. OSHA's construction standard, 29 CFR 1926.1153, lists jackhammers and handheld chipping tools in Table 1 with water at the point of impact or a shroud and dust collector, plus a respirator with an assigned protection factor of 10 when a worker uses the tool outdoors for more than four hours a shift. The duty is the contractor's, as employer. Write 'contractor follows 29 CFR 1926.1153 Table 1 controls' into the scope anyway, and add that no dry chipping or cutting happens beside open windows, patios or entries.

Write a scope bidders can price

Build the scope from the consultant's elevations so every bidder prices the same walls. Lines to include: crack sealing by the slurry method, per linear foot; patch removal and replacement, per square foot, lath included where needed; full re-clad by elevation, per square foot, including barrier, lath and weep screed; sheathing replacement at a unit price per sheet, photographed before it is covered; a test patch in an out-of-the-way spot that the board approves for color and texture after it dries; and the finish, either a matching finish coat or a named coating over the full elevation. Hollow areas grow once removal starts, so set an allowance on top of the base price and require written approval from the board's contact before the crew goes past it. Bid thresholds: in Texas, services over $50,000 go through a bid process under Property Code 209.0052(c). Florida HOAs bid anything over 10 percent of the annual budget including reserves (720.3055), condos anything over 5 percent (718.3026), and neither has to take the low bid. Colorado follows your documents. Florida condo buildings of three or more habitable stories must include waterproofing and exterior painting in the structural integrity reserve study under 718.112(2)(g), so fund a large stucco job from that line.

A sample timeline, motion and owner notice

A sample order: month 1, consultant walk and sounding; month 2, report and maintenance chart review; month 3, fix gutters, grading and sprinkler heads; months 4 to 5, scope and bids; month 6, contract, permits and test patch; then one building at a time in dry weather, with the consultant checking each opened wall before it is closed. Sample motion: 'Motion to approve the contract with [contractor] for stucco repair at Buildings [numbers] under the [consultant] report dated [date], for a base price of $[amount] plus unit-price work up to an allowance of $[amount], paid from the exterior reserve, and to authorize [director] to sign.' Sample notice, sent two weeks before each building starts: 'Stucco repair at Building 3 starts Tuesday, May 4, and should take about [number] working days, weather permitting. By May 3, please move grills and furniture four feet from the walls and take down anything mounted on the stucco. Expect chipping noise on weekdays from 8 a.m. to 5 p.m., and keep windows on the work side closed. Patched areas will look darker until the finish coat goes on. Questions go to [contact], not to the crew.'

Mistakes boards make

Hiring a painter to caulk every crack and calling it fixed. Patching before the gutters and grading are corrected, so the same walls crack again. Letting new mulch or pavers bury the weep screed a year later. Patching smooth stucco without budgeting to recoat, then fielding complaints about a checkerboard wall. Skipping the lead question on a 1970s building. Signing a lump sum for work nobody can measure until the stucco is off. File the consultant's elevations with the permanent records and send the final costs to the reserve study provider. Our guide on planning an HOA exterior repainting project covers the recoat that usually follows.
