Frequently Asked Questions
Huntington Beach offers a mix of coastal luxury homes, suburban single-family residences, and modern condos, with a median home price exceeding $1.2 million. The market caters to upscale living, featuring Spanish-inspired and contemporary designs, often with proximity to the beach driving premium values.
Families thrive in Huntington Beach thanks to top-rated schools like Huntington Beach High, safe neighborhoods, and abundant outdoor activities, from surfing to community events like the US Open of Surfing. However, the high cost of living can be a challenge for some households.
Yes, Huntington Beach is one of California’s most expensive coastal cities, with a median home price around 1.2million and average rents surpassing 3,000 per month. The cost of living is roughly 40% higher than the national average, driven by high demand and limited inventory.
Oceanfront rentals in Huntington Beach and other California coastal cities are extremely scarce and expensive, with fierce competition and waitlists common. A one-bedroom near the sand often costs over $4,000 per month, making beachside living a luxury.
Yes, California’s Housing Accountability Act and laws like SB 9 penalize cities that resist state-mandated housing plans. For example, Huntington Beach faced legal action in 2023 for refusing to approve affordable housing developments.
Los Angeles is tackling its affordability crisis through innovative measures like streamlined approvals for backyard ADUs, transit-oriented density near metro lines, and voter-approved funding for affordable housing. The city has fast-tracked over 1,200 affordable units in 2024 alone, while new state laws now require cities to permit multifamily housing in formerly single-family zones. Community land trusts and “missing middle” housing projects are creating below-market options, with some new micro-unit developments offering studios under $1,500/month—30% below traditional rents. Though challenges remain, these reforms are slowly bending the cost curve while preserving LA’s neighborhood character.
Orange County’s high prices result from limited coastal land, affluent buyers with high wages, luxury demand in cities like Newport Beach, and Prop 13’s tax incentives reducing turnover of existing homes.
Single-story homes dominate due to earthquake safety concerns, mid-century ranch-style trends, and zoning laws that restrict building heights in some areas, though newer suburbs are increasingly incorporating two-story designs.
