Hawthorne Sunrooms & Patios is a sunroom contractor serving Manhattan Beach, CA with custom sunrooms, patio enclosures, and sunroom additions built for the city's tight lots and salt-air conditions. We have been working in the South Bay since 2019 and know the Sand Section, Tree Section, and Hill Section properties that make Manhattan Beach unlike anywhere else in the region.

Manhattan Beach homes range from compact 1940s cottages to large three-story new builds, and the right sunroom design for each is completely different. Our custom sunrooms are designed from scratch around your property - lot dimensions, setback requirements, existing roofline geometry, and the coastal exposure your specific address receives - so the finished room looks like it belongs on your home rather than a catalog item dropped onto it.
Manhattan Beach homeowners who want a room they can use any morning - including June Gloom mornings when the marine layer sits low and damp over the city - benefit from a fully conditioned four-season room with low-E insulating glass and a ductless mini-split system. The investment holds up well in a market where high-quality home improvements retain value at above-average rates.
Manhattan Beach patios often go underused because salt air and coastal wind make sitting outside less comfortable than it looks. A glass patio enclosure captures the light and views while blocking the wind and keeping moisture off the furniture. For flat-roof homes with a rear terrace or deck, an enclosure can turn a rarely used outdoor deck into a year-round room.
Older Manhattan Beach homes sometimes have enclosed aluminum patios from the 1970s and 1980s that are drafty, poorly lit, and built with framing that was never specified for coastal salt-air exposure. Sunroom remodeling replaces the aging structure with current framing, insulating glass, and properly sealed perimeter details that hold up against the coastal moisture this city sees every year.
Vinyl framing is a practical choice for Manhattan Beach homeowners who want low long-term maintenance in a coastal environment. Vinyl does not corrode, does not need repainting, and does not react to salt air the way steel or untreated aluminum does. It works well in the Tree Section and Hill Section where lots are a bit larger and the homes tend toward classic residential profiles rather than modern flat-roof designs.
A screen room gives Manhattan Beach homeowners a way to enjoy the ocean breeze on comfortable evenings without sitting in direct wind. Powder-coated aluminum screen frames hold up to the salt air far better than painted steel, and for compact Sand Section lots where a full glass enclosure would crowd the rear yard, a screen room achieves a good balance of weather protection and outdoor feel.
Manhattan Beach packs enormous variety into under 4 square miles. The Sand Section near the Pier has lots as narrow as 27 feet, many with homes built right up to the property lines and virtually no side-yard staging area. The Tree Section a few blocks inland has tree-lined streets and a mix of original bungalows and newer builds on somewhat larger lots. The Hill Section further inland has the most space and the largest custom homes, but it still sits close enough to the ocean that salt air is a factor on every exterior project. These three neighborhoods are not interchangeable, and a contractor who treats them the same will produce work that does not fit the site.
The city's building department processes a high volume of permits relative to its size because renovation and new construction activity in Manhattan Beach is steady. The Manhattan Beach Building and Safety Division has specific requirements for sunroom and enclosure projects, and plan check times reflect the department's workload. We account for that timeline in every project schedule we give homeowners here. Santa Ana wind events in fall also put stress on roofing, glazing seals, and perimeter caulking - materials and installation details matter more in Manhattan Beach than in more sheltered cities.
Our crew works throughout Manhattan Beach regularly, and we understand the local conditions that affect sunroom contractor work here. The Sand Section near The Strand is the most logistically demanding part of the city to work in - narrow lots, limited street parking, and homes where the only path for materials runs through the front door or a side gate just wide enough for a two-wheel dolly. We account for that access challenge in our project planning before we ever show up with a crew. The Tree Section and Hill Section give more room to work, but the older homes in those neighborhoods often have original framing dimensions or roofline details that require custom modifications to match properly.
Manhattan Beach Boulevard runs from the Hill down to the Pier, and Sepulveda Boulevard is the main north-south commercial artery through the city. The Strand - the famous paved beachfront path - defines the western edge of the Sand Section and is a daily gathering place for the neighborhood. The Manhattan Beach Pier at the foot of Manhattan Beach Boulevard is the most recognized landmark in the city. Marine Place and Highland Avenue neighborhoods near the pier are among the most active renovation areas in the South Bay.
We also serve homeowners in El Segundo, which sits just north of Manhattan Beach and has its own compact, well-established residential neighborhoods. Homeowners in Hermosa Beach, immediately south of Manhattan Beach, call us for patio enclosures and screen rooms on the same type of compact beachside lots.
Call or fill out the contact form and we follow up within one business day. Knowing which neighborhood you are in and whether your lot has rear alley access or tight side access helps us prepare before the site visit.
We come to your property, measure the space, review the roofline and existing structure, and identify any access or staging constraints specific to your lot. The written estimate covers all costs - materials, labor, permits - so there are no surprises when the project starts.
We prepare and submit the permit application to the Manhattan Beach Building and Safety Division. Plan check typically runs 4 to 6 weeks. We handle the follow-up so you do not need to track the process yourself.
Once permits are in hand, construction typically runs 4 to 10 weeks depending on scope and site access. We coordinate city inspections as required and walk you through the completed room before we close out the project.
We know the Sand Section, the Tree Section, and the Hill - and we plan every project around the specific lot and home we are working on. Call or contact us for a free on-site estimate in Manhattan Beach.
(424) 307-8485Manhattan Beach is a small, dense city of about 35,000 people sitting directly on the Pacific Ocean in the South Bay area of Los Angeles County. It covers just under 4 square miles and is known for some of the highest real estate values in California. The city has three well-defined neighborhoods that locals refer to by name: the Sand Section, which runs closest to the beach and has the smallest lots and the most tightly packed homes; the Tree Section, a few blocks inland with tree-lined streets and a mix of older and newer builds; and the Hill Section, further inland with larger lots and more room between homes. The historic wooden Manhattan Beach Pier sits at the foot of Manhattan Beach Boulevard and is the city's most recognized landmark. According to the city's history, Manhattan Beach incorporated in 1912 and grew steadily through the postwar decades alongside the South Bay's aerospace industry.
The housing stock in Manhattan Beach is dominated by single-family detached homes, though teardown-and-rebuild activity has been high for two decades. Original beach cottages dating to the 1920s and 1930s still exist in the Sand Section alongside three-story custom builds that go right to the lot line. The Strand - the paved beachfront path along the sand - is a defining feature of daily life for Sand Section residents. We regularly work in both Manhattan Beach and neighboring Hermosa Beach to the south and El Segundo to the north, giving us a clear picture of how the coastal South Bay's building stock and permit requirements compare across cities.
We work throughout Manhattan Beach - Sand Section, Tree Section, Hill Section - and understand what each part of the city requires. Contact us today and we will follow up within one business day.
