Stunning from the curb, mature olive trees and lush landscaping frame the welcoming porch and timeless, crisp white facade. Inside, the four-bedroom, three-bathroom main home opens into a light-filled great room beneath a vaulted, wood-planked ceiling, where a cozy fireplace anchors the living space. The gourmet kitchen is a natural gathering place, featuring white shaker cabinetry, classic subway tile, and a large eat-at island. Just off the kitchen, a generous dedicated dining area is bathed in natural light beneath a bespoke chandelier. An additional room with a bar and beverage refrigerators is ideal for dining or lounging and opens through accordion doors to the private backyard. A walk-in pantry with integrated laundry keeps everyday life beautifully organized. The primary suite is a true sanctuary, with folding glass doors that open directly to the pool, plus an en suite bathroom and generous closet space. Additional bedrooms offer flexibility for family, guests, or a dedicated home office. Step outside and the resort experience comes to life. Set on an 8,600+ sf lot and enclosed by mature hedges, the backyard provides complete privacy around a pool, spa, and fire pit. An outdoor dining area, thriving garden, and plenty of room for lounge seating and an outdoor television make this a setting to enjoy from sunny afternoons to evenings under the stars. Across the patio, the former garage has been transformed into a fully equipped ADU with a full kitchen, full bathroom, vaulted beamed ceiling, and a bright, airy feel. Folding glass doors and a pass-through window to an outdoor bar counter connect it seamlessly to the yard. Use it as a guest house, a poolside entertaining space, a studio, or a private suite for visiting family. Beyond your own backyard escape, enjoy the best of Eastside Costa Mesa living with all that Newport Beach has to offer right at your fingertips. The boutiques, coffee shops, and restaurants along 17th Street are just moments away, along with neighborhood parks and the Back Bay trails. The beach, Newport Harbor, and the OC Fair & Event Center are a short drive away, with convenient access to the 55 and 405 freeways. ## Location - **Address:** 259 E 21st Street, Costa Mesa, CA 92627 - **County:** Orange - **Neighborhood:** Eastside Central (ECCM) ## Listing Agent - **Name:** Mark Taylor · **License:** 01877391 - **Brokerage:** Compass - **Broker Phone:** (949) 438-4340 ## Photos ![259 E 21st Street - Photo 1](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f231300562r.jpg) ![259 E 21st Street - Photo 2](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f893215854r.jpg) ![259 E 21st Street - Photo 3](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3294233334r.jpg) ![259 E 21st Street - Photo 4](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f2197246367r.jpg) ![259 E 21st Street - Photo 5](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f4045730581r.jpg) ![259 E 21st Street - Photo 6](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3178741890r.jpg) ![259 E 21st Street - Photo 7](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f2820994854r.jpg) ![259 E 21st Street - Photo 8](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3391875391r.jpg) ![259 E 21st Street - Photo 9](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f953132561r.jpg) ![259 E 21st Street - Photo 10](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f566336052r.jpg) ![259 E 21st Street - Photo 11](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3998862752r.jpg) ![259 E 21st Street - Photo 12](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f1221004291r.jpg) ![259 E 21st Street - Photo 13](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f697475570r.jpg) ![259 E 21st Street - Photo 14](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f1242116118r.jpg) ![259 E 21st Street - Photo 15](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f203281168r.jpg) ![259 E 21st Street - Photo 16](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f845654568r.jpg) ![259 E 21st Street - Photo 17](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f615230492r.jpg) ![259 E 21st Street - Photo 18](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3126915894r.jpg) ![259 E 21st Street - Photo 19](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f420586072r.jpg) ![259 E 21st Street - Photo 20](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3481744026r.jpg) ![259 E 21st Street - Photo 21](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3079482212r.jpg) ![259 E 21st Street - Photo 22](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f2902249760r.jpg) ![259 E 21st Street - Photo 23](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f1968273628r.jpg) ![259 E 21st Street - Photo 24](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f4179029722r.jpg) ![259 E 21st Street - Photo 25](http://lh.rdcpix.com/9a4a2120c664f438d51268a8a0d85c9el-f3414132786r.jpg) --- **MLS#:** NP26230733 | **Updated:** 2026-10-30 **Source:** listhub *Copyright © 2026 California Regional Multiple Listing Service, Inc.
