Interior and Exterior House Painting in Los Angeles and Across Southern California

House painting is the washing, scraping, sanding, repair, priming and coating of a home’s interior and exterior surfaces so the finish protects the building and holds up under the sun for years rather than seasons. Green Design and Build is a licensed, bonded and insured general contractor (CSLB #1110975) based in Van Nuys, serving homeowners across Los Angeles County, Orange County, Ventura County, western Riverside County and western San Bernardino County. A full exterior repaint of a typical single-story stucco house in Southern California usually runs about a week on site, and most interior rooms take a day or two.

What we paint

• Interior painting — walls, ceilings, trim, doors and built-ins, with drywall repair and texture matching.
• Exterior painting — stucco, wood and fiber-cement siding, trim, fascia, eaves, garage and front doors, railings and gates.
• Surface prep and repair — pressure washing, scraping, sanding, caulking, stucco patching, wood rot replacement, rust treatment and priming.
• Cabinet and trim refinishing — de-glossing, sanding, priming and spraying cabinets, vanities, doors and trim.
• Specialty coatings — elastomeric coatings for cracked stucco and direct-to-metal enamels.

Prep is the job

Paint does not fail at random; it fails where washing, sanding, priming or caulking was skipped. Our exterior sequence is the same on every house:

1. Wash. Pressure wash the whole exterior to remove chalk, dust and loose paint, at lower pressure on old stucco and wood so water is not driven behind the finish.
2. Scrape and sand. Take every loose, peeling or alligatored area back to a sound edge, then feather sand so the edge does not show through the new coat.
3. Repair. Fill and texture stucco cracks, replace rotted fascia, trim and siding, re-flash where water got in, and treat rust on metal.
4. Caulk. Seal gaps at windows, doors and trim joints with an exterior-grade, paintable caulk, not a bathroom silicone paint will not stick to.
5. Prime. Spot-prime every bare, repaired or stained area; full-prime chalky stucco, bare wood, a much lighter color change, or a surface with a history of peeling.
6. Coat. Two finish coats of the exact product and sheen in your contract, back-rolled on stucco so the paint is worked into the texture.

Interior work follows the same logic: patch, sand, match texture, prime repairs and stains, caulk trim, and mask everything else.

Stucco, wood siding and trim behave differently

Most houses in our area are stucco, and most stucco from the 1950s through the 1980s carries hairline cracks from settling and seismic movement. A 100 percent acrylic exterior paint handles hairlines well and lets the wall breathe. Where stucco has a dense network of cracks, or takes wind-driven rain, an elastomeric coating makes sense: it goes on several times thicker than paint and stretches over cracks as the wall moves. The trade-off is that it traps moisture if the wall behind it is wet, so we do not put it over stucco with active water intrusion from a bad roof edge, a missing weep screed or an unflashed window; the leak gets fixed first.

Wood fascia, siding and trim are where exterior paint jobs are won or lost. Wood moves more than stucco, end grain wicks water and nail heads rust through, so rotted boards are replaced rather than filled, primed on all faces including cut ends, and painted with a flexible acrylic trim enamel. Metal gates and railings get rust removal, a rust-inhibitive primer and a direct-to-metal enamel.

Sun, color and fade

South- and west-facing walls fade and chalk first, dark colors fade fastest, and a deep charcoal or navy on a west-facing wall in Woodland Hills or Corona will look noticeably lighter within a few years whatever is used. When a client wants a dark exterior we recommend a premium line with UV-resistant pigments, say so if the color is likely to fade unevenly, and test it on the actual house at a size large enough to judge. Flat and low-sheen finishes hide stucco flaws and fade more gracefully; satin and semi-gloss belong on trim and doors.

Pre-1978 homes: lead-safe practices under the EPA RRP rule

Much of the housing in the San Fernando Valley, Pasadena, Glendale, Long Beach and older Orange County was built before 1978, when lead-based paint was still legal in homes. Under the federal EPA Renovation, Repair and Painting (RRP) rule, paid work that disturbs painted surfaces in a pre-1978 home has to follow lead-safe work practices. The only exemption is minor work that disturbs six square feet or less of paint per interior room, or 20 square feet or less on the exterior; a full scrape-and-repaint is well past that.

On a repaint that means the paint is tested or assumed to contain lead; open-flame burning is prohibited; heat guns run only below 1,100 degrees; power sanding is allowed only with HEPA dust collection at the tool; the ground is covered out to 10 feet from an exterior wall and floors out to six feet from interior work; and the area is cleaned with HEPA vacuums and wet methods, then verified. Homeowners must receive the EPA’s pre-renovation pamphlet before work starts. This adds time and cost, which is why an estimate that promises to “just wipe down” a 1955 ranch house is not a bargain.

Low-VOC coatings under SCAQMD Rule 1113

Paint sold for use in Orange County and the urban portions of Los Angeles, Riverside and San Bernardino counties is regulated by South Coast Air Quality Management District Rule 1113, which caps the volatile organic compound (VOC) content of architectural coatings. The current Table of Standards limits flat and nonflat paints to 50 grams per liter of VOC; primers, sealers, stains, rust-preventative coatings and waterproofing sealers to 100 grams per liter; and lacquers, varnishes and sanding sealers to 275 grams per liter. Ventura County sets its own limits under Ventura County Air Pollution Control District Rule 74.2. The professional lines sold here already comply; for bedrooms and nurseries we use zero-VOC interior lines on request, which also lets families sleep in the room the same night.

Permits and HOA color approval

Painting by itself does not require a building permit; Los Angeles County Building and Safety and the other building departments in our service area list painting, papering and similar finish work among the jobs exempt from one. Painting comes under a permit only as the last step of a permitted remodel, addition or ADU.

What does need approval in many Orange County neighborhoods, and in many Santa Clarita, Simi Valley and Corona communities, is the color. Master-planned communities across Orange County have CC&Rs that require architectural committee sign-off on exterior colors, often from an approved palette. California Civil Code section 4765 requires the association to follow a fair, reasonable and expeditious written procedure, give you a written decision, and explain any denial and offer reconsideration by the board. We prepare the color submittal with manufacturer, product and color codes for each surface and do not schedule exterior work until the written approval is in hand.

Where we do this work

Across Los Angeles County the work is dominated by 1950s–70s stucco ranch houses in the San Fernando Valley and older wood-trimmed homes in Pasadena, Glendale and the Los Angeles flats, where pre-1978 lead-safe practices apply to most exteriors, hillside lots add scaffold planning, and HPOZ historic zones in the City of Los Angeles can restrict exterior changes. In Orange County the houses are newer and CC&R architectural review drives the schedule more than the building department does. Ventura County brings coastal moisture in Ventura, Oxnard and Camarillo that pushes exterior work later in the day and favors mildew-resistant coatings, while Thousand Oaks and Simi Valley sit in and near fire hazard zones where clients often pair a repaint with vent and eave upgrades. Western Riverside County, from Corona and Eastvale to Murrieta, has the hottest summers, the strongest fade on dark colors, and newer housing largely under HOA color control.

How long does a paint job take?

Job	Typical duration on site
Single interior room	1–2 days
Whole-house interior, 1,500–2,500 sq ft	1–2 weeks
Exterior, single-story stucco in good condition	About a week
Exterior with significant stucco or wood rot repair	2–3 weeks
Kitchen cabinet refinishing	4–7 days, plus cure time before heavy use

Exterior work also waits on weather: stucco must dry after washing, acrylic coatings should not go on below about 50 degrees or on to a wall that is hot to the touch, and we do not paint into rain. Valley summer work starts early and follows the shade around the house.

How much does house painting cost in Southern California?

Painting is priced by the amount of surface, its condition, the number of coats and the product line, and on most homes the repair and prep line moves the number more than the paint does. The ranges below are typical Los Angeles budgeting ranges, not a quote; your written estimate itemizes every surface, repair, product and sheen.

Separate guides break each side down further: interior painting cost (per room and whole-house ranges, paint tiers, cabinets, wallpaper removal) and exterior house painting cost (stucco versus wood, prep, elastomeric coatings, two-story access).

Painting job	Typical Los Angeles budgeting range	What moves the price
Single interior room, walls only (about 12 x 12 ft)	$500–$1,500	Ceiling and trim, wall repairs, dark-to-light color change
Whole-house interior, 1,500–2,500 sq ft (walls, ceilings, trim, doors)	$6,000–$18,000	Ceiling height, doors and windows, texture repair
Exterior, single-story stucco, 1,500–2,000 sq ft	$6,000–$14,000	Stucco repairs, wood trim, one coat vs two, gates and garage doors
Exterior, two-story or wood-siding house	$12,000–$30,000	Height, siding condition, wood rot, lead-safe containment
Elastomeric coating instead of standard acrylic	Adds roughly $2,000–$6,000	Low coverage per gallon; cost climbs with wall area
Kitchen cabinet refinishing, average kitchen, sprayed	$3,500–$9,000	Door and drawer count, existing finish, color change
Stucco crack and patch repair before painting	$500–$2,500	Number and width of cracks, texture matching
Wood rot replacement (fascia, trim, siding)	$500–$3,000	Linear feet, height, flashing or sheathing damage

Two rules shape how we quote. California limits the down payment on a home improvement contract to $1,000 or 10 percent of the contract price, whichever is less, and a contractor may not collect for work not yet done; a painter who asks for half up front is asking you to ignore state law. And hidden damage found after washing or scraping, most often dry rot behind fascia, becomes a priced change order for your approval before we repair it. Our post on what to ask before hiring an exterior painter covers the contract questions in detail.

Frequently asked questions

How much does it cost to paint a house exterior in Southern California?

Painting the exterior of a typical single-story stucco house in Los Angeles usually falls in a budgeting range of about $6,000 to $14,000, and a two-story or wood-sided house runs roughly $12,000 to $30,000. The condition of the stucco and wood, the number of coats and the product line move the number more than the color does. These are typical ranges, not a quote.

How long does it take to paint the outside of a house?

An exterior repaint of a single-story stucco house in Southern California usually takes about a week on site when the surfaces are in good condition. Homes that need extensive stucco patching, wood rot replacement or lead-safe containment can take two to three weeks, and rain or heat can add days.

Do I need a permit to paint my house in Los Angeles?

Painting a house in Los Angeles does not require a building permit; Los Angeles County Building and Safety and other local building departments classify painting and similar finish work as exempt. Painting falls under a permit only as the finish stage of a permitted remodel, addition or ADU, and even then no separate painting permit is issued.

Does my pre-1978 house need special painting precautions for lead?

A house built before 1978 is presumed to contain lead-based paint unless tested, and paid work that disturbs paint on it falls under the EPA’s Renovation, Repair and Painting rule. The work has to follow the rule’s lead-safe practices: no open-flame stripping, no power sanding without HEPA dust collection, ground and floor containment, and HEPA and wet cleanup. The minor-repair exemption covers only six square feet of paint per interior room or 20 square feet on the exterior, far less than a repaint disturbs.

What is low-VOC paint and is it required in Southern California?

Low-VOC paint is a coating with a limited amount of volatile organic compounds, the solvents that evaporate as paint dries and contribute to smog. In Los Angeles, Orange and western Riverside counties, South Coast AQMD Rule 1113 caps flat and nonflat house paints at 50 grams per liter and most primers at 100 grams per liter, so any professional paint sold in the region already meets the limit. Zero-VOC interior lines go further and suit bedrooms and homes with young children.

Should I use elastomeric paint on my stucco house?

Elastomeric coating is worth it on stucco with widespread cracking or on walls that take wind-driven rain, because it goes on far thicker than paint and stretches over cracks as the wall moves. It is the wrong choice over stucco with an active leak from a roof edge, a window or a missing weep screed, since it can trap moisture in the wall. On sound stucco with only hairline cracks, a quality 100 percent acrylic paint is usually the better value.
