Zillow Pricesqft

Every real estate investor knows the single most important metric for comparing properties: price per square foot. But Zillow doesn't show it on search results — you have to click into every single listing, find the square footage, and do the math yourself. That's dozens of clicks just to compare a handful of homes.

Zillow Price/SqFt fixes this in one install.

The extension automatically calculates and displays a color-coded $/sqft badge directly on every listing card in Zillow search results. No clicking, no math, no spreadsheets — just scan the page and instantly see which properties are great deals and which are overpriced.

**How it works:**
A content script runs on zillow.com and scans every property card for price and square footage data. It calculates price per square foot and injects a small, color-coded badge right next to the listing price. The badge updates automatically as you scroll, filter, or navigate — including Zillow's infinite scroll.

**Color-Coded Value Guide:**

- **Green (< $150/sqft)** — Great value
- **Blue ($150–$300/sqft)** — Average market rate
- **Orange ($300–$500/sqft)** — Above average / pricey
- **Red (> $500/sqft)** — Premium pricing

**Key Features:**

- **Automatic calculation** — price per sqft appears on every listing card with sufficient data
- **Color-coded badges** — instantly identify deals vs. premium listings at a glance
- **One-click toggle** — enable or disable badges from the popup without leaving the page
- **Infinite scroll support** — new listings get badges as they load via MutationObserver
- **SPA-aware** — works seamlessly with Zillow's React-based single-page app navigation
- **Multiple extraction strategies** — handles Zillow's evolving DOM structure with fallback selectors
- **Lightweight** — badges are injected inline next to prices, no overlays or z-index conflicts
- **Rental filtering** — automatically skips rental listings ($/mo) to avoid misleading calculations

**100% local. No servers. No accounts. No data collection.**
Zillow Price/SqFt runs entirely in your browser. It reads price and square footage from the page, does the math locally, and displays the result. Nothing is sent anywhere. No analytics, no tracking, no external API calls.

**Built for:**
Real estate investors, house hunters, property flippers, real estate agents, and anyone who wants to compare home values efficiently on Zillow without opening every listing individually.
