Los Angeles, CA House Plans

Modern California hillside home with warm timber, large glazing and a low planted terrace at golden hour

Los Angeles has a remarkable residential design heritage, from Spanish Revival to mid-century modern, and steep land costs that make every square foot count. Hillside lots, fire zones and earthquakes all add to the challenge.

What to Plan for in Los Angeles

Check hillside rules

The city's hillside ordinances can limit size, height and grading, so check them before you assess what fits.

Design with fire in mind

Many neighborhoods are in very high fire hazard severity zones, with strict requirements for materials and vegetation.

Blur inside and out

With a mild climate, courtyards and sliding walls extend small homes outward.
