Renovation and DIY: Costs, Permits, Tools and Viral Builds — 2026-09-17
This week, German DIY retail law shifted significantly as the Federal Court of Justice ruled that Obi cannot trademark its signature orange color, ending a long-running dispute with competitors Hornbach and Globus. Meanwhile, Japanese home center giant Cainz launched its 2026 autumn/winter product line focused on "relaxing interiors" and opened a new small-format renovation specialty store in Tokyo. In the US, professional remodeling indices showed slight cooling, while new battery technology from major tool brands continues to redefine cordless performance standards.

German court ends Obi’s exclusive claim to "Obi Orange"
On September 16, 2026, the German Federal Court of Justice (BGH) ruled that the DIY chain Obi cannot hold a trademark on its characteristic orange color. The court determined that the shade lacks sufficient distinctiveness to serve as a brand identifier, effectively allowing competitors like Hornbach and Globus to use similar orange hues in their branding. This decision concludes a years-long legal battle and reshapes visual identity strategies across the European DIY retail sector.
Cainz launches autumn/winter collection and opens small-format renovation store
Japanese home center leader Cainz announced its focus products for the 2026 autumn/winter season on September 15, 2026, centering on the theme "Relaxing Interiors" with new offerings in food, gardening soil, and system kitchens. Concurrently, on September 16, 2026, Cainz opened a new small-format specialty store, "Cainz Reform," inside the Odakyu Department Store in Machida, Tokyo. This move signals a strategic shift toward integrating renovation services directly into high-traffic urban retail spaces rather than relying solely on large suburban warehouses.
US Remodeler Index cools as costs and uncertainty temper growth
The U.S. Remodeler Index fell three points from the first quarter to 57 in Q2 2026, according to data reported by Qualified Remodeler. The decline reflects shorter project backlogs and increased consumer caution regarding costs. While still above the break-even level of 50, this slowdown aligns with broader economic indicators suggesting that while remodeling activity remains robust compared to new construction, the pace of spending growth is easing.
"Collected-over-time" aesthetic replaces pristine minimalism in home design
A survey of 50 design professionals by Houzz indicates a major shift away from perfect, minimalist interiors toward a "collected-over-time" look for Fall 2026. This trend emphasizes personal history, mixed textures, and lived-in comfort over sterile perfection. The shift impacts material choices and renovation scopes, favoring restorative work and vintage integration over full-scale modernization, which may alter the demand for certain high-end finish materials.

Local view
Germany: Media outlets including Der Spiegel and Zeit Online covered the BGH ruling extensively, framing it as a victory for competition and a blow to Obi's long-held marketing strategy. The decision is being discussed as a precedent that could affect other color-based trademarks in retail.
Japan: Local business news from Ryutsuu Biz highlighted Cainz's expansion into department store formats, noting how the retailer is adapting to urban density constraints by offering specialized renovation services in smaller footprints.
Context & numbers
- Renovation Costs: Average spending among top-percentile homeowners rose approximately 77% in recent years, increasing from $85,000 to $150,000 per project, indicating a significant widening of the gap between standard and luxury renovations.
- Cost Per Square Foot: Current 2026 estimates for renovation costs range widely from $15 to $300+ per square foot depending on scope and location.
- NAHB RMI: The NAHB Remodeling Market Index stood at 61 in Q2 2026, down one point from the previous quarter but remaining solidly above the break-even level of 50.
On the radar
- DeWalt Battery Platform Update: DeWalt has announced changes to its battery platform expected in summer 2026, promising full backwards compatibility with existing FlexVolt and 20V MAX tools, though specific dates and pricing remain unconfirmed.
- Tabless Battery Rollout: Major brands including Milwaukee, DeWalt, Ryobi, Makita, and Bosch are aggressively rolling out tabless Li-ion cell technology (e.g., Bosch EXPERT, DeWalt POWERPACK, Makita XGT) which claims up to 96% more power output in some cases, potentially rendering older battery stocks less competitive in the coming months.
