Planning your project
What Inglewood's homes mean for your room addition
Most homes in Inglewood are older. The Census reports that 78.1% of housing units were built before 1980, and the median year built is 1960. Plan your addition with that age in mind.
Check the existing foundation, bracing and connections before new framing ties into the house. Ask about electrical panel capacity, and ask whether lead-based paint testing or asbestos checks are needed where old walls will be opened. These are things to check, not certainties for every house.
The Census also reports that 36.2% of occupied housing units are owner-occupied, so many homes are rented. If you own a rental, plan the work around your tenants and keep them informed about schedule and noise.
The median value of owner-occupied homes is $792,800. Use that figure only as a general guide when you decide how much to put into your home relative to its value.

The typical path for a room addition in Inglewood
Check what your lot allows
Confirm your setbacks, height limit and lot coverage with the city before you design anything. Older lots can have unusual conditions, so ask early.
Plan the design and engineering
Work with the builder on a layout that fits the existing house. Ask how the new space will connect to the current structure and roofline.
Submit for plan check and permit
Your plans go to the city for plan check. Ask the builder what documents they will prepare and what the city will review.
Foundation and framing with inspections
Before pouring, the builder checks the foundation and connections in an older house. Framing follows, with inspections at the stages the city requires.
Roofing and mechanical work
Roofing and mechanical work come next. Plan how the new roof will match the older roof and exterior of the house.
Electrical and plumbing rough-in
Electrical and plumbing rough-in happen before walls close. Ask whether your panel has capacity for the new space, and schedule the required inspections.
Finishes and final touches
Once inspections pass, finish walls, floors, paint and fixtures. If you rent the home, keep tenants informed about work near their space.
Final inspection and closeout
Complete the final inspection with the city. Keep your permit and inspection records with your home documents.
Room addition questions for Inglewood homeowners
Is a room addition harder to build in an older Inglewood home?
Possibly. The U.S. Census Bureau reports that 78.1% of Inglewood housing units were built before 1980, and the median year built is 1960. Older homes often need checks on the foundation, bracing, electrical panel capacity and older materials before a new room is tied in. Ask the builder what they would inspect in your house before design starts.
What should I think about if I rent out my Inglewood home?
The Census reports that 36.2% of occupied housing units in Inglewood are owner-occupied, so many homes are rented. If you rent out the property, plan the work around your tenants, keep them informed about dates and noise, and ask the builder how they will protect their space during construction. Confirm your own obligations with the city before you start.
How should I think about budget compared with home value?
The Census reports a median value of $792,800 for owner-occupied homes in Inglewood. Use that only as a general guide. Think about how much you want to put into your home relative to its value, and set a budget range before you ask for a quote.
What older-home questions should I ask a builder?
Ask the builder to explain the foundation, bracing and how the new framing will connect to the existing structure. Ask about electrical panel capacity, and whether lead-based paint testing or asbestos checks are needed where old walls will be opened. These are things to check, not certainties for every house.
What should I check before I request a quote?
Start by confirming what your lot allows, including setbacks, height and lot coverage, with the city. Then ask the builder to check the license status of any contractor you consider with the CSLB, the Contractors State License Board.
